Stance Stance Revolution 2 at Motorama 2024: Yes, It Did Happen!

Quick note: I re-organized how the individual project threads were categorized on the left sidebar. Yeah, “Done!” and “Not Done!” stopped being useful some time in 2009… But hey, the best time to make a change was 15 years ago and the second best time is now. Everyone’s grouped by type of build, whether it be van or robot or silly scooter. My next insurmountable multi-year sit down for an hour challenge is to update the static pages and make new ones.

Many moons ago, I finished a Stance Stance Revolution. I did in fact go to Motorama right after the fact, even if I’m years late with the event update! In fact, another entire Motorama is happening right this moment, but I’m sitting this one out due to having focused too much on Real Life and the Robot Trap House, not getting around to putting either SSR or Susquehanna Boxcar back together yet.

So, after Vantruck’s “redemption trip” in 2022, and doing a clean in-and-out with Coronavan in 2023 due to surrounding life and work obligations, it was obviously time to debut Operation IDIoc….

Nope, guess who hasn’t been above the Mason Dixon line since 2019? I decided it was Mikuvan’s turn to make the run back up to my weird culturally adopted second home (as my friends joke all the time that I’m a closeted central Pennsylvanian).

At this point in time, I hadn’t yet trusted Vantruck enough to make the long trip to Harrisburg. In retrospect? It would have been just fine. But I decided risking it at the time wasn’t worth the cascading costs – see, at least the Tail of the Dragon was within one AAA tow radius, and with Mikuvan they don’t have to send out a different truck after finding out the first one was too small despite me telling them exactly what it is.

Somewhere north of Roanoke, stopping both for lunch and to peruse the hardware store for stuff I forgot to bring, such as….

… a weapon lock for Stance Stance. I grew fond of using these big D-style hitch pins after doing it for Sadbot for Comicpalooza. I just got one big enough to thread through both discs at once. Bringing it into the store and test fitting pins one by one definitely drew a lot of conversation, and there were even some BB watchers!

The rest of the trip was completely uneventful, which is an abnormality given Mikuvan’s history of enjoying the Shenandoah Valley scenery just a bit too much. I cruised into Harrisburg around dinner time and got my usual hotel room at “whoever still has vacancy and not bugs”.

Here we go! It’s Saturday morning and everything’s passed inspection. I got to drive it in the real arena surface it’ll be on, and I confirmed that the worm drive was a surprisingly good idea. Weapon spinup was rapid, a consequence of me designing more for torque than raw speed because I’ll likely be using these things as reaction wheels often.

The only issue was the roughly 3mm of ground clearance. That was not something I could make better on the fly here, but I figured I’d use the weapons as said reaction wheels if it got hung up briefly.

The first fight was against a two-part multibot, two little TPU bricks working together named BDT. Not to be confused with Jamison’s legendary DDT. The fight is at 1:54:40 in the day 1 beetle stream.

This was an endurance fight, and SSR didn’t endure that well. It spent much of the time (as designed) bouncing around the arena on the blades, but either that or one of the hits caused a weapon motor shaft to break off.

If I had to guess, something bent just enough that the gear’s hub got caught on the disc. This was something I had thought may happen because the gear hub sits outside of the swept circle of the blade’s hub, so it could in principle hit the spokes. A lot of gear-driven weapons make sure the blade hub is a little larger than the center axis of the pinion for this reason, but I didn’t have the weight this time around to make the blade hub larger in diameter. Something else will have to give here.

The other weapon broke down because one of the motor wires got loose and was minced by the gear drive or blade. That’s just first-fight debugging finding all the ways you didn’t zip tie everything like you thought you did.

Knocking down the weapon drive system was quick, allowing me to assess the roots of the damage. I think the two-piece motor and weapon shaft mount (that bracket) might still be just a little too flexible, so maybe I can redesign it with the carbon fiber plate also covering part of the area to increase rigidity and unify things more too.

Because I didn’t want to sacrifice a spare weapon motor yet, I simply retrieved the shaft from one of the spare drive motors (of which I had more) and smashed it together again and sent it.

And send it did. SSR died a valiant warrior’s death against Mulsanne, a P1 beetle with a scorpion’s tail style spinning disc. This video is at 4:36:32 in the stream capture. This was a fight full of knocking chunks off each other until Mulsanne lined up the best possible killshot and cut through the 1mm carbon fiber baseplate and 3 out of 4 cells of the battery!

I honestly think I hit him more off-kilter and upside-down than driving on all 4 wheels. One of the weapons died about midway through, leaving me to actually take myself seriously and use the remaining disc as a reaction wheel to turn and drive for the last 30 something seconds.

Oof. What a way to go through. SSR skating around identifying as an undercutter or gyro walker for much of the time somehow made the whole affair worth it. I have enough spares to put this thing back together as-is, but am going to make some mods to the weapon designs as I mentioned earlier.

Not too sure what as of yet, since the thing is so packed full of gear that there is scant little to just remove weight from. Plus, I’m not sure how much thicker of a baseplate could have stopped that weapon anyway. It might be better to just trim some beef from the weapon hubs and go for reliability changes. Just don’t get hit, duh.

On my way back down, I decided to detour after staying a night near Roanoke again. This time, I went back through a different portion of western North Carolina to explore some roads that I wanted to visit, but because the east-of-Asheville area is a little long for a day trip, haven’t gotten to.

I do need to just spend a week wandering the whole place. I keep saying that, but am very bad at actually putting things down and doing it. Hence my recurring mention of day trips here and there.

It turns out the ass end of Route 197 isn’t paved, but no big deal. With excellent sightlines down the mountain, I just played some Rally Van Simulator.

A friend somewhere at the bottom of the mountain before I found my way back to US 74.

The ship landed some time after midnight Monday into Tuesday, upon which I neglected to unload any of the robots or gear for a solid week. No issues at all out of Mikuvan this time (which I again emphasize how unnatural this is and may indicate a credit line building for a future epic road trip explosion), except maybe the new radiator I installed the year before was too effective. I may have to check the thermostat and see if it’s stuck open some.

These events transpired right before I turned my attention to Vantruck to finish “Patch 1.1” and hit the Tail of the Dragon in April. So I spent a bunch of time after that in post project hangover mode, not touching a robot again until August in preparation for Dragon Con.

i bought a mill

Yep, finally. After selling the Benchmaster, Master of Benches last January, I have finally picked up another one. The same points I made then still stand, really. The hangar isn’t wired up for 240 power (or meaningful amounts of power in general) yet, so having a Bridgeport would largely mean having a 2000 pound paperweight. I don’t believe in round column mill-drills. This meant waiting for one of the relatively few numbers of square/box column bench machines to show up on the used market… and those things keep their value.

I decided to sell on the Benchmaster because while it’s very cute and collectible, it was missing “modern mill” features I cared about. Mostly, that little thing didn’t have a quill. It was probably the most annoying thing about using it, since a drill chuck took up much of the Z axis travel and only the bed/knee feed was available. It’s patterned on American milling machines of the early 20th century, and most of them did not have quills or heads set up for Z travel either. Back then, drilling was considered much more of a separate operation from milling.

Luckily, a local antique machine collector responded to my sale ad. That’s really the best possible outcome for the thing, as it’s 100% a rock solid vintage machine that weighed probably thrice as much as a typical modern “mini mill” and would be at home with bulky cast iron friends of similar vintage!

Twenty ice ages later, I finally made a move when a Grizzly G0704 mid-sizer came up for sale locally at what I call “regret pricing”

Here it is, mounted to the heavy bench I built just for such a machine all the way back in November of 2023… and which had been used largely to pile unsorted tooling and cutters since then, because there’s been no mill.

This one came from middle Georgia, and the seller had bought it a few years ago to convert to a CNC mill. That’s a fairly common reason people buy the G0704, as it turns out, since it is a fairly basic machine that comes with a DC spindle motor, rudimentary controller, and no digital scales.

In the sale was also the entire CNC conversion kit; it’s a generic Chinese package with big stepper motors and pulleys/belts, and the Linux CNC computer to run it. And finally, a set of metric R8 collets and a kit of (carbide, as it turns out) endmills from 3mm to 12mm.

Basically, dude got in a bit over his head, ran out of time due to life obligations, and the project never materialized. Completely reasonable decision to sell it upriver to me, and I’m not gonna dunk on that. After all, “Got in over my head” is my M.O. and only because I don’t have life obligations. Above, we’re preparing to pull the thing out of his basement with a baby excavator (which was later used to sling load everything into Vantruck)

I want a baby excavator now. I mean, I always wanted one after seeing them in catalogs and on websites, but witnessing one in real life was another thing completely. This was a well constrained little day trip after all was settled.

When I got home, I craned the mill out of Vantruck’s bed onto my handcart, then set the crane up again inside the minishop to pluck it back off the handcart and onto the bench. I marked the holes in the base onto the bench when I pushed the thing to where I thought I liked it. Then I craned it up out of the way just a bit so I could drill the holes, and made the final bolted attachment. I’m not using the stand it came with, but I might turn it into something later on like a grinding/sanding station with wheels that lives in the hangar.

Well… now I have a mill on a bench. The big problem is, I had to kick much of my collection of mill tooling and other as-of-then unconstrained tooling and cutters off that bench onto the lathe bench. I now was forced to finally do something about organizing all that!

I made another Pegwall using called-up reserve materials, purchased from the first time around last year. This one is just a half size, 44 inches wide, to fill the space up to the “bedroom closet” which is still kind of an unallocated space (The floor drill press migrated into the hangar as part of this effort).

The Huot dispenser drawers I bought long ago were emptied out and repurposed. I resold as packs/sets basically all of the taps and endmills in them, as the majority were sizes I already owned in some way. I kept only a handful of duplicates and ones I didn’t own yet (like thread-forming taps).

Basically I just relabeled by hand the drawers I needed based on the sizes of tooling I owned. I am not a job shop, I don’t need 3 different drawers each of Plug/Taper/Bottoming type taps, per size. Just the sizes I need to use with some spare empty spots for future expansion.

Somehow I had collected enough 1/2″ reduced-shank (Silver & Deming) drills to make a full 33/64″ to 1″ set by 1/64″ increments… with a bunch to spare, and several larger than 1″ drills! I decided to make wood block organizers like I’ve seen a bunch of times. Some “nice” wood from Home Depot (I’m not even sure what wood it is, besides Nicer Than The Usual 2×2) and some marking and drilling later, and they were done.

The hanger brackets attached to them are for use with plastic organizer bins. I just screwed 2 of them onto each drill bit forest.

One can think of this as kind of the “drilling and tapping” wall. The tooling I had enough of to be annoying, but not enough of to make a comprehensive organized drawer in a tool chest, all got homes in little labeled plastic bins. Drills, taps, countersinks, counterbores, and miscellaneous hole-making implements like my stash of spot weld cutters, and so on all live here. There’s plenty of space on this pegwall for things to grow and evolve, even though it looks a bit barren right now.

The little pink drawer block contains Dremel accessories, because why be boring and buy just the black drawers!?

Of course, with a labeling and organizing spree comes the way I prefer to label and organize things.

I decided to get a new set of “the basics” for the mill just to make sure I have everything I needed besides cutters. Like, I’ve had an odd edge finder here and there, and lost my DTI many moons ago (it’s probably still in a tote or basket somewhere, and I’ll find it immediately after sorting stuff).

This was a fun chance to see if anyone else has invented machine shop goodies too. I found this R8 collet rack that would fit all the metric and inch ones I had accrued. There were more “creative” designs for racks and holders as well, but I’m more a simplicity guy. Some times, people going ham making 3D printed organizers and shadowboxes for everything feels more like making a set for a Youtube channel – which, quite honestly, many of those are.

A long time ago, I designed up a small tray to hold something (it was in the Robot Trap House CAD folder) and so I just changed some dimensions and pattern multiples to turn it into general purpose endmill and cutter holders.

Thoughts about making up a Gridfinity system or something did cross my mind, but again… making it useful for me first. I wasn’t in the mood to plan out that far.

As long as it fills up my toolbox drawers and I can scribble on it. There’s an additional tray set, miniaturized, on the top deck to hold things like the edge finders. Rapid access up top, more esoteric as we move lower. The next drawer under this one currently just has a R8 drill chuck and fly cutter/face mill in it, but it’ll probably be where the R8 tooling will live.

So now the only thing the mill is missing is digital scales, which I’ll attend to at some point. For now, driving it by eyesight and Sharpie scratch marks is sufficient. At least I can readily shave parts down, make keyways and motor shaft flats, and more complex bolt patterns again, and now with a quill and Z feed too!

Funny enough, the very first job I needed the mill for didn’t strictly require a mill but the rigid, dial-able setup made things much easier. I wonder what it is…
