The Belated Motorama 2023 Recap: Return of the Susquehanna Boxcar

Somehow in the midst of the most unscoped, sprawling big-integration project I’ve ever found myself in, I managed to pop out yet another dumb robot! Last² year for Motorama, I spawned the Susquehanna Boxcar, which was a quick-build 30lb Sadbot using pretty much only on-hand components (I mean…. I allowed myself a trip to the hardware store and some random bolts from McMaster). So, for 2023, as I was seeking to distract myself from constantly wrenching on the ven, I decided to bring the bot back. In terms of actual timeline, this build occurred some time between The Stuffening’s conclusion and The Driveshaftening.

While the original build was conceptually sound and drove alright, the mild-wound brushed 550 motors with the spur gearing ended up being prone to burning out. Even with the RageBridge current limiting set rather low, the windings were fine enough that prolonged pushing (or binding in the drive side) would begin cooking them. By the end of the event and in the rumbles, it could barely move.

The easier way out was to just go brushless. This is a statement that, about 10-something years ago on this very website, was almost an absurdity to hear… but that’s the march of technological progress and Chinese meme manufacturing! I had a large stash of SimonK-flashed AfroESCs left over from those days, as well as a few other random SimonK/BLHeli enabled controllers. Nowadays, the new hotness is AM32 which is very promising so far for a couple of builders, but I don’t own any of that hardware yet. This build of Susquehanna Boxcar will help me draw down my existing stash of parts and equipment even further, so it’ll make sense to take the jump to something more modern later on.

The plan was pretty much the same as the first build. Just four motors with a single open spur gear stage to the wheel. The motors I picked were some NTM Propdrive 2836s from HobbyKing, probably destined originally for some kind of Roll Cake or Colsonbot. I had three of the same motors, so I decided to get an extra few from another builder. Next, to give these motors even more of a leg up on the world, I specified 6 tooth pinions, to be custom-made from cold-drawn “pinion wire” (gear on a stick) to be purchased from SDP-SI.

Yes, within the first half hour, I’d already broken my “No spending money” rule. It’s now… No Spending Money™

The smaller pinions allowed a total reduction of 10:1 to the 60 tooth drive gears. This thing will be quick, but I had no doubt it would drive well.

One of the issues (of many) that plagued Susquehanna Boxcar last time was that the four motors were independent from each other. To do this effectively in a 4WD chassis, each motor really needs a lot of torque and power overhead in case you get tilted up (which WILL happen) by an opponent or engage in a pushing match which tends to load the back set of wheels. The little mild-wound 550s….. did not have this.

In lieu of figuring out how to re-engineer a chain or belt drive onto the thing, I decided to just plop a giant bull gear in the middle. With some geometric massaging, I found that I could fit a 73 tooth gear in between the two wheel gears, offset slightly, while keeping the motor pinions from barely touching it.

Oh, yeah, the other constraint was that I wanted the motors as far inboard, towards the center of the bot, as possible. This was to make them less obvious targets as well as to let me have more volume for electronics and batteries. So, all together, this design path ended up working out quite well.

The construction method will be the exact same as version 1, using literally the same bars of UHMW. This is the generated left frame rail. Like before, I’ll be using a 3D printed template/pattern to spot the holes before drilling them, in lieu of having a milling machine with a readout or doing it High School Charles style with all-manual layout.

The drill gearbox for the Multifunction Poking Implement is mounted identically, but pushed forward a little more. There were two reasons here. One, to give me more space for electronics, as the motors are spread farther apart than before and so the contiguous space at the very back has changed in shape. And two, because I wanted to be able to run a larger sprocket on the poker hub. Having the motor directly underneath limited the sprocket selection significantly.

The poker hub this time uses a #35 sprocket instead of a #25 for greater durability. I wrote off using this #35 sprocket (from my big basket of random sprockets) last year because it was larger than the #25 I ended up going with. But now, with the motor moved, it can fit.

I went ahead and modeled the bull gear that bridges the front and rear drive wheels. It’ll spin on two FR6 type ball bearings and be unceremoniously suspected on a single shoulder bolt with a locknut. I’ll have to see if I can even make the tolerance stackup of manually drilling these holes work with it!

I generated the template that is to be used for the frame rails, and made sure to design it so it’s as hard to look at as possible. There’s no real reason for the many unrelated holes, just an aesthetic choice. If anything, it made the print process longer and made it less rigid.

The template aligns with the UHMW stock using three dowel pins. Two on the bottom side for the parallelism, and one touching the upper corner.

The Makening

The first step is to take apart the old and salvage what I can for the new! It wasn’t that much, sadly. The only things I could really reuse from this chassis is the outer steel frame itself which left the event mostly intact, and the four axle bolts.

Using the template to pilot drill the holes did work well enough, but I still needed to use the Benchmaster, Master of Benches for a counterboring operation to make pockets for the drive motors. I didn’t have a good means of ensuring that a Forstner bit (to make the flat-bottomed hole) started aligned with the pilot hole if I did this on a drill press, so I just sucked it up and spent a few hours counting dial revolutions. Still, this was more of a “close enough” operation, as the motor’s mounting axis is determined more by their countersunk mounting screws. As long as they didn’t touch the side of the pockets…

All the parts are labeled with their orientations because I will definitely mess up making the correct side otherwise!

Going back to construction methods I haven’t really utilized in a bunch of years, really dating back to my pre-machining era. These frame rails were just squared up and clamped together, with the holes laid out by hand.

In a day and age where most people default to 3D printing frames, and it’s common for newbies to think you have to have a 3D printer to get started building, I still think there is value to a frame banged together from UHMW blocks. It’s workable with almost all tools, and is a solid contiguous mass for you to zip things together wherever you want (versus 3D printed hollow infills… reminds me of drilling into drywall trying to mount something at the house)

I expect this mod to go very poorly.

That’s a 35mm class outrunner motor which shares a bolt pattern with the RS-550 sized drill motor. I was going to cram this into the drill gearbox after boring the pinion out to 5mm. Putting something like 3-4x the power of the drill motor through that gearbox is most likely going to make it very angry. My guess is the output stage pins will shear or I’ll start blowing gear teeth.

I went ahead and prepared both of the 3536 motors I had for drill gearboxes. It’s easy to keep making parts in the same sitting once you get rolling and all the tools are already out and set up.

Test fitting the bull gear here. “Shoulder bolt” decayed very quickly into “well, i’m too lazy to remove this cap screw and nut”. I found that I had the tiniest amount of axis position adjustment because the threads on the screw are a very slightly smaller diameter than the hole.

To my utter surprise, the gear mates all worked! Only a small amount of backlash was present and the bull gear didn’t really need any special treatment, like forcing off to one side of the tolerance/slop distance. Now, I used to do 32-pitch gear mates by hand on the drill press back in high school, so if I can’t even manage 24-pitch nowadays that would be quite the blunder.

Moving onto the Multifunction Poking Implement, it’s put together the same as last time: Just a square tube, appropriately drilled through, welded to the sprocket

As I touched upon before, I started with a #35 sprocket this time and turned it down (very painfully – this was a lot of sitting there cranking Tinylathe 0.5mm of feed at a time) to the thickness I needed. Then I just apply some quick blasts with Limewelder using a steel tube as a locating dowel in the center.

Now, for the drill gearbox sprockets, I had to get a bit creative. The smallest #35 sprockets I owned were these 8-toothers… but they already had a bore of 3/8″. The drill gearboxes have a 3/8″-24 threaded output shaft. There’s too little meat on the hubs to bore it out and sleeve it (I’d basically cut the sprocket bit off the hub if I tried boring it out).

The solution: Well, the welder is already out and warmed up. I just filled the hole up with Weld™. It’s like a Direct Edit button, but for real life.

Next, I chucked the sprocket up and treated it like I would any other! Drilling a center hole, then successively larger holes (the weld alloy is harder than whatever this is made of), then finally running the 3/8″-24 tap through it.

That worked amazingly. So that’s pretty much all the mechanical work going into this bot. Conceptually very simple, using techniques I’ve second-natured for years now, and not much to go wrong. Perfect zero-brain-cells-left build for a time I was mostly preoccupied with planning the L.E.W.D.

I even went and purchased a new Harbor Freight Multishovel to complement the slightly beat up (but serviceable) one from last year. All I do to these is remove the handle and stuff the stump into the adapter sleeve that sits in the hub tube. The folding telescoping sleeve thing still works. Unless destroyed, I can transform it back into a Multishovel.

Top and bottom lids for the rear section are once again made from 1/8″ G-10 grade Garolite laminate, a pleasant and multipurpose material. Pleasant, except the part where it slowly consumes your HSS/carbon steel tools from abrasiveness and also leaves little fiberglass splinters everywhere. The top and bottom screws got an upgrade to 3/8″ lag bolts. No particular reason here besides unifying the tools needed to fix this thing.

Between then and now, I grew a reel of TPU filament that was only used a little. I decided to expend more of it making the electronics cave for this thing. It’s just sandwiched in place between the top and bottom plates, then retained on one side by the steel box frame and on the other by the protruding axle bolt heads.

It’s designed to fit a 4S 1.8Ah battery, compared with the 7S flat battery last time. Nothing wrong with that battery per se, but I was using the smaller AfroESCs which weren’t rated for that voltage input. Keeping the voltage lower also kept the bot’s calculated top speed from being comically high (like 30+mph, unrealistic to achieve in the box) and makes blowing everything up much less likely.

The power “switch” and power distribution was kept simple with a single gigantic squid assembly. The big solder joint in the middle brings together four 18 gauge drive motor controller wires, a single XT-60 on 14 gauge for the poker, and an auxiliary JST-RCY (literally “a JST Connector” when left unspecified, by the way… not many people know the actual product line name) for whatever else I want, like gaudy LEDs.

This was not fun to solder together, but I was in no mood to design some kind of bus bar or power distribution terminal block system.

After some more massaging and fineries, here is the Susquehanna Boxcar for 2023! I was highly pleased with how this bot drove, actually. The four SimonK-based drive ESCs were put into reversible mode with non-synchronous PWM (they can both add power, but not regenerate from each other – no fighting through the gears) but idle-throttle braking enabled. That way the bot still stopped quickly when I centered the transmitter stick and didn’t keep coasting.

The Motoramming of 2023

For the Motorama, I was in charge of making the trophies once again using asslaser69. I got creative this time and changed the design to use a lighted base, which we liked and so the organizers commissioned a boatload of them from Amazon. This was an cute little change from the rushed-together laser cut trophies of 2022 which were made because AAAAAAAAAHHHHHHH WE DIDN’T DO IT

And so, once again, we deal with the consequences of having me be in charge of something. IYKYK, IYDK,DGI.

I elected to do a “clean trip” this time. Vantruck was obviously not available for the job like it was in 2022. Plus, at this point, I was beginning to cull my random van buying and breakdown related expenses, appraising my resources in preparation for the New Robot Trap House. So, the soulless-but-least-likely-to-explode van it is.

My first (and only) real tournament match was against EVA (stream archive link), which used a pushy configuration for the match. Right around halfway through, I lost a motor on the left side, and later on the mutual pounding also (like I suspected) sheared off the planet gears inside the ol’ crusty drill gearbox that had been brushless-swapped. It was trapped upside-down :(

I was slated for two fights that day, and taking the thing apart to get at the motor and the drill gearbox took longer than I counted on. It turns out the extension cable I made to get to the ESC had pulled out of a connector joint I thought was well-taped, but I had to take the bot apart enough to get to that point to find out. The drill gearbox and motor just needed outright replacement.

You’re only guaranteed 20 minutes turnaround at most of these events, Motorama included, and that can come to haunt you really quickly if the matches ahead of you move fast due to knockouts, or if people forfeit fights. The usual 2-ish hours I was hoping to have turned into only 45 minutes or so. So with my time having come and gone, I decided to just prepare Boxcar for a series of really funny rumbles.

And no Susquehanna Boxcar moment would be complete without a comically sized vegetable hanging off the end of it. Behold, the Papaya of Redemption. As I promised, I headed out to the only Asian grocery within like 50 miles or something and picked up a couple of dumb… uhh, end effectors.

Here’s the stream link for that rumble! It didn’t do that much during the rumble because the Papaya of Redemption almost immediately broke the spare drill gearbox, and then became stuck against the frame.

Once that was very rudely and inconsiderately removed by Phenomenon, I guess it ripped something completely apart inside with the toss from its weapon (maybe turning a stripped gear or two into powder), and I had some vestigial function left on the Multifunctional Poking Implement. Upon which I got promptly stuck sideways on the wall.

I also agreed to a grudge fight afterwards against Big Cookie, which is a bristlebot using the purposefully unbalanced shell to wiggle around on a series of tilted wire brushes. It demonstrates translational movement like behavior under some circumstances, but hits crazy hard because it’s basically entirely weapon.

For this fight, the Danger Potato made a return, because… why not.

I assembled a composite drill motor out of the wreckage of the two I brought, so I can swing the Danger Potato. This was 100 percent not a good idea, just as I suspected. And I think I understand why I usually spend money on robot parts.

By the end, both of the robots were thoroughly painted in taro starch. Here’s the stream archive time link so the erotic taro-grinding action can be witnessed!

I said Cookie hits hard. Look at the frame on this thing. It’s turned completely into a parallelogram!

Well then… that basically retires this Susquehanna Boxcar because I’ll need to remake the frame entirely to get it back in working order. So, if I bring it back again, I might be forced to… you know, spend money on it or something. Maybe I can use one of the leftover P61 gearboxes I have from 30Haul. Sadly, the days of competitive bots being made from power tool particles is mostly done for except the local back yard stuff, like my very own near-and-dear Robot Battles at Dragon Con. There’s just better gearboxes to handle the power of brushless and lithium.

Boxcar basically lives in a pile of its own wreckage in a tote to this day, because immediately after returning from Motorama, I went into Operation IDIocracy rescue mode. I scrapped the parallelogram along with about 700 pounds of other random metal detritus before the big move. Now that the New Robot Trap House is functional, I am certainly considering bringing it back for said Dragon Con this year!

Motorama 2022: Susquehanna Boxcar and Justice for Vantruck

On a somewhat rainy Thursday evening before the weekend of Motorama, after Susquehanna Boxcar was all put together, I began loading my Pelican cases decade-old Harbor Freight aluminum suitcases (who can afford Pelican cases??) of robot gear into Coronavan so everything was ready to hit the road in the morning. The plan was to get there over the course of Friday and unload everything so I don’t need to rush on Saturday morning, and maybe help with some setup as well.

Friday morning, I woke up and pulled everything out of it… because shit’s about to go down.

That’s it, we’re doing this now.

The last time I tried to have you do something useful, you randomly broke down on I-81 in Virginia. Vantruck had not wandered north of the Mason Dixon since the very last week of 2019. Of course, after replacing the fuel injectors and harness inside the FiTech throttle body unit, it’s been just fine for everything I’ve had it do, including pulling Murdervan, Snekvan, and several jeeps back home.

Still billowing blue smoke and missing a cylinder, but what else is new. We’re just going to dive right into this after an inspection of fluids, belts, whistles, and dingles.

But before that, over the course of the week, I was making Motorama trophies! I took on this responsibility after the original maker had Personal Problems come up. They were going to be laser cut and engraved. It just so happened in the months prior to this that I had picked up a 18×18 75W laser cutter on the cheap.

As with everything else lately, I owe a post on the process of getting that junker up and running again with replacing the tube, squaring the gantry, and so on. But, trophies.

I made a few test cuts in different colors of acrylic I had hanging around, then had the organizer order a few sheets to me through McMaster. Design three was what we ended up going with, though I personally prefer the clear plastic. The stands were already made, so I just had to supply the display panels.

asslaser69 (as it’s named in the print driver selection box) handled this first major job exceedingly well. Before this week, it had only cut random little trinkets as tests. To prepare, I bought a hydroponic weed growing aeration pump as the forced air blast source and it was running an aquarium pump submerged in a 5 gallon car wash bucket.

Look, all the pieces are there. Even if they’re wrong.

One of the upgrades I want to do eventually is a long-focus (100mm) lens and a gas lens, so it can get through some thicker stuff. It’s honestly just fine right now for basically everything you’d use a CO2 laser cutter for, but muh scope creep.

Of course, when you let me make visual products, you are going to have shit like this be part of it.

Common rule of thumb for being my co-worker: If you know, you know. If you don’t know, don’t Google it. Especially not on the lab’s network.

With Vantruck given the green light and my Extremely Large Miku print strapped in the back seat, it was time to ship off northward!

immediate regret

The journey was uneventful (good… misbehave and the methy junk man will come for you), and it was quite pleasant to be heading to a familiar haunt of mine. Motorama had been canceled for 2021, and I wasn’t in any position to turn around a trip back in 2020. I romance the I-81 corridor a little in my personal make-believe TVTropes page in my head, but it does form an axis between me and the friends and adventures I left behind up north.

It would be nice for it to hurt a little less though.

Just a little bit less, please.

Remember, this was the weekend before Russia really lit off World War III. Gas, while post-economic reopening expensive, wasn’t Summer of 2022 tier expensive. I can’t imagine making this trip at all if it was even a month later.

12 hours after leaving, I rolled into the Pennsylvania Farm Show Complex. Not a peep along the way, though the oil usage was on the order of 1/2 quart or so (Hard to tell if it’s just that I didn’t give it an hour or so to meet back at the bottom).

This should be more of a 9-10 hour trip (having made the run to Norwalk using the same route a few times) but Vantruck’s preferred speed is more 65mph instead of the 85mph+ I keep trying to pull with Coronavan.

I unloaded everything and went around to help set up the arena and said hello to everyone. But, before I could leave, I had to attend to a Vantruck thing:

It just wouldn’t be a van trip without me fixing something in the parking lot somewhere. On the way in the gates, a security guard let me know that my right side brake light was out. Odd, since I hadn’t noticed the turn signal blinker acting up. It turns out the running light filament was out, so the turn signals using the main filament would still be good. I did manage to break the bulb apart while extracting it from the socket, though.

In a stroke of … well, typical luck, someone at the event just had a few 3157 bulbs sitting in their car, and at a robot event we all have pliers and grabby tools of some sort, so this was otherwise a fast repair. Makes me wonder how long it’s been out – it was dark at least since northern Virginia, and I don’t hit the brakes on the highway. Vantrucks do not have to follow laws.

And that, kids, is how I found myself holding an inflated 6S lithium battery pack, standing in a Waffle House in Harrisburg, PA.

It’s the next morning and time to get serious. Everyone’s here now and going through inspection and testing!

Been a good long time since I’ve seen any of the bots or the builders. This is “Starfather”, a 30lber from the P1 team and the larger version of “Starchild” which is right next to it. It won’t be the last time I see this thing either.

One thing I can appreciate is that Norwalk’s multiple tournaments per year, all full-contact in nature, has really pushed the evolution of the 3lb through 30lb classes. Designs were on point this Motorama. A lot of bots were very clean and professional looking, some from builders that were just starting out with their first kitbots or 3D printed 3lbers in 2019 when NHRL really kicked off.

A small 12 pound tribute to Poison Arrow.

The rise of more on-demand machining services in the past few years has really let robot builders leverage the competitive pressure and creative use of materials/processes. It’s way easier to achieve robots that “look like a thing” nowadays – 5-10 years ago I could easily see this being a square aluminum bar frame, for example.

A Sportsman class flipper with some serious machine and welding work on it.

Hell, even bots that are “traditionally built” are on point nowadays. This thing – appropriately named Pipe Bomb – is a full body drum spinner with mostly 3D printed internals but hand-cut UHMW plastic wheels and endcaps. The giant ring bearings supporting the drum had all the grease washed out of them and replaced with some light oil for less drag. It spent much of the tournament sideways trapped on its wheel faces, but took an absolute beating and kept running.

This ultra-stanced conical wheel drive flipper named Pigeon was interesting. It let the bot be very low sloped on the sides without compromising wheel track spacing and wheelbase.

Some high quality machine work coming out of Wedge Industries (who has since stopped machining things in order to machine more epic things) this is Crunch Time, a scaled down tribute to Quantum/Spectre from Battlebots and King of Bots.

It turns out when your load case is that of a skull, it’ll generate you a skull

– alex, maybe

Told you this wasn’t the last time you’d see Starfather. It turns out that’s my first match. The only top-attack robot in the bracket and I somehow drew it, with the robot that has the most exposed shit going on up top. For giggles, I obtained a Brandon Sign from the dealer hall (this is a rural motorsports event, there is plenty of Brandon Signage) and bolted it to the Multishovel to give Brandon Zalinsky, the builder/driver, something to think about.

Well there wasn’t much thinking he had to do, because it didn’t end well for Susquehanna Boxcar. Starfather pretty much nuked everything on top. I left the arena functional, but with one dysfunctional motor and more possibly smoked, but still moving.

The weapon got in a direct hit on the pokey stick shaft, which is hollow and so folded like a lawn chair. It also nicked the sprocket and bent it sideways. This bend was unable to get straightened out and compressed again to to the point where the chain could wrap around it, so it was eventually cut out.

Starfather’s weapon also put some clean gashes into the Multishovel. Amazingly, it did not break off its mount, but just backed the locking collar off its thread.

The most important damage was to the drive motor, where it cleaved through the UHMW mount and completely broke (and bent) the motor. I only had 1 spare 555 mild-wound motor with me, and it was going to replace this one. The other three motors all smelled kind of interesting too, so they were not long for the world.

My next matchup was against Pigeon – the ultra-stanced face-wheel drive flipper seen above. This was a pushing match that I could not win, so I just drove around to the best of Boxcar’s ability. No damage sustained in this fight, but between the 4 drive motors I think I had 2.5 left by the end.

The next day, I stopped by the local Asian grocery tore to pick up some snacks and a new weapon for it since I was planning to enter as many rumbles as I could:

Nicknamed “Danger Potato”, it was a taro root that we impaled on the end of one of the pokey-sticks and wrapped in caution tape to prevent it from coming apart.

Danger Potato in action in the 30lb rumble (Starting at 04:38:40 or thereabouts, if the time link doesn’t work). I basically ran around like a dumbass until the motors all smoked, and then just sort of flailed around.

So what lessons have I learned from Susquehanna Boxcar? Nothing. It served its purpose beautifully: Be basically free to build and be an entertaining meme. The mild-wound 550 printer motors were a bit of a wash, but I knew that going in. I’ll definitely just change them to some equivalently-powered brushless motors and bring it back next year. The top side could use some work, but hey, it’s all stuff I found in piles in the garage. The drivetrain itself took no damage, nor did the internals beyond the chunk taken out by Starfather.

This was a nice break from van-related work and reminded me that robots can still be fun. Between BattleBots and having to take myself seriously, and NHRL’s focus on the prize, robots have more and more seemed like a chore as of late. Honestly, besides this coming BattleBots 2022 season, I think I’ll only stick to Sportsman-ish events like Motorama 30lbers and Dragon Con from here on.

After everything was wrapped up and done, I was presented with a prize for Vantruck. The Jeep Bros that I keep fetching wreckage in Alabama sheds for found this pickup truck roof wing at an estate auction. I’ve been looking for something like this for a good while since buying new ones is expensive, and mildly considered building my own.

Largely just to completely The Look – it’s not like I will ever regularly tow a Portable Convention Center & Hotel which could use a forward-mounted wind deflector.

Of course, it wasn’t time to go home quite yet. In another “This isn’t a van trip without fixing something in the parking lot”, early on Sunday morning I went to pick up a part that I suspected was giving me some trouble on the way up, and definitely confirmed it once I arrived.

That’s the mechanical, viscous-coupling fan clutch at the front of the engine. I began to suspect it had seized up because during the trip northward, as temperatures fell, I noticed the coolant temperature never going above 150-160 degrees, dropping some times as low as 145 degrees.

140 degrees is the threshold for the FiTech control unit going back into warmup mode. The fuel mixture became richer, and my gas mileage dipped to even more horrifying levels. If the fan clutch seizes, then the engine fan will always be turning and therefore overcooling significantly in the cold winter night air at highway speed.

This was a quick enough fix, and I could reach in behind the radiator to undo the fan hub nuts, then unbolt the fan from the clutch.

I finished this in about 15 minutes in the Motorama back parking lot, and as you’d expect of a gearhead motorsports event, about a dozen people stopped by to ask if I needed help or supplies. I’m sure I’m far from the only one trying to resuscitate a patient on the ground here. After installation, I caught up with some people for dinner and started bombing it southbound…

Only to encounter more pain I stopped for the night near Roanoke, VA and continued Monday morning on a little detour.

Alright, I’m conveniently positioned to cross the Blue Ridge and Smokies at some point, and somebody hasn’t been back here since Dragon Con 2019. So we know what this means…

It was a very quiet morning on the Tail of the Dragon. Being in the middle of winter, the resorts were all shut down and the photographers were not out in force (though you can still beckon and commission them for a fee, ahead of time, if you so desired), and I took my time with the mountain crossing.

In all, the trip was completely reasonable (for me, anyway – reasonable implies at least one or two wrenching oopsie moments are designed in from the start) and it was a good way to recast a hobby that had, in recent days, felt more like an unpaid internship *ahem* Battlebots than bashing it up with friends and onlookers.

From my return, I focused more on getting the 7.3 IDI engine from Snekvan rebuilt; it had already been extracted from the van by New Year’s Day 2022 and I was halfway into tearing it all apart. I had an eye for getting Vantruck swapped and ready for Dragon Con 2022; this also means I’m like 11 Operation IDIocracy posts behind.
