Operation RESTORING BROWN 5: The Road to Reassembly

Alright, so the most labor-intensive drudgery part of this whole process is now behind me – namely, the actual painting of the thing. Everything from here on will be a breeze again, right!?

Ideally all my going above-and-beyond just removing something for reinstallation later, paired with front-loading a lot of the interior repair work (mostly trying to delay the inevitable painting!), means the whole thing will all collapse back into itself and stop taking up so much floor space.

I hope. What takes more space to park than a vantruck? A vantruck which is disassembled into two halves and a pile of itself! Well, guess I’ll find out!

But first, the travelling and growing index:

  1. Episode 1 – the initial teardown of the house of horrors
  2. Episode 2 – Welding and repairing the major roof seam holes
  3. Episode 3 – Wrapping up electrical loose ends, some times literally
  4. Episode 4 – Actually painting the cab… using a Harbor Freight paint cannon

The first item to be remounted was the visor… which was also the first painting experiment with its attendant errors and imperfections, so naturally I wanted to get it above my eye level quickly.

One of my overcompensating fixes was buying ArmorCoat screws for everything exposed to the elements – also some times called zinc-aluminum coating. We use these aplenty at the #VapeShop, and I picked up a bunch of different sizes I needed in sheet metal/threadforming style as well as regular hex cap screws.

Where I couldn’t get Armorcoat, I went for 400-series stainless steel to maximize compatibility with plain steel.  The entire rest of the thing will rust away around my new screws!

Also in the same series of tasks was re-installing the windshield trim. Just like when I had to get Mikuvan’s windshield replaced, all of the little clips that hold this trim piece on all broke away as I removed them. But there was a twist!

These weren’t plastic clips, but actually steel ones in a plastic insert. The plastic inserts themselves were almost completely turned to powder, so I obviously wasn’t gonna save them. The steel clips themselves were almost rusted through or deformed beyond repair as I pulled on them. I hunted around for a while and found what is basically just the steel insert for them, but sold as the complete part.

Geometrically it made sense, but these things took a lot of insertion force. I obviously (looking at that photo) bought these clips before painting – in fact I got them almost immediately after discovering the windshield frame rust hole – but did not open the package and actually think about it until now.

There’s probably a specialized plier that splits them open or something, but I wasn’t about to take chances with a deadblow hammer and a chisel right near the windshield. So, I actually flattened them a little in a vise to allow for gentle tapping installation.

It was finally time for the custom center stop light module to be mounted. This exercise was quick – just tighten the screws into the well nuts and stop when you feel some resistance, which is when the rubber has flared out behind the pilot hole.

This is the replacement Sparton airhorn I got on eBay. New old stock hanging out in someone’s basement for a while, so absolutely perfect for my needs.  The chrome trumpets on my existing ones are completely pitted and chipped with zinc/bronze casting rot, and the internals of the sounding unit/flappy bits had also deteriorated. In fact I thought the air line was broken all this time, but after taking the roof liner inside off, I found that it was fine.

Finding a fitting for this assembly was an adventure. It seemed to exist in a size directly between 1/8 NPT and 1/4 NPT threads. 3/16 NPT doesn’t seem to be a real size, and I measured the thread minor diameter at about 0.41 inches, which was too big to be a M10, yet too small to be a M12.

In fact, the thread pitch lined up suspiciously with a 1/4-20″ size bolt I swirled in there as a makeshift thread gauge to check if my eye-crometers were miscalibrated. They were also non-tapered, and didn’t seem to have a conical seat or anything that would indicate it’s a modern standard.

 

After asking around some, I discovered that 7/16-20 hydraulic fittings are a thing. I literally took the drawbar out of our Bridgeport mill and threaded it in there to check – perfection!

Except… what?  How about I just drill and tap this thing for 1/4″-NPT and have it exist in a future supported ecosystem with easy to find parts? That’s exactly what I did – blew these threads right off, then drilled and tapped for 1/4-NPT.

With NPT fittings installed, I had fun testing this thing (and cleaning it out) using an air compressor. Sadly, it wants about 30 PSI before it will even sound, which puts it out of the realm of most of the cheap “direct drive” air horn compressors which are small single-stage vane pumps.

At the full 120 PSI, this thing is quite a….. hoot, you might say. It’s lower in pitch than I expected after Alex Horne and I found out his were very high pitched.

As I’d have to actually rig up high pressure air, these are likely going to remain decorative for the foreseeable future.

I suppose the intention of a straight-threaded fitting is because it’s also supposed to help mount the thing. That’s how the old one came off – I unscrewed (read: sheared) the old fitting and off with it came a thin panel nut. The idea being you put this on the outside of the roof and thread the combined fitting + locknut in from the bottom, tighten the fitting, then jam the locknut against the bottom of the roof panel.

Well, you can technically do this with NPT threads too, just the taper might make for a looser fit on one end for the nut, but they do exist.

I found out after a test fit that the stock NPT nut was too tall, so lacking a lathe quickly on hand, I just reduced its height by some manual surface grinding.

The next step was to cut out a gasket. I bought a big roll of EPDM foam rubber which will continually make an appearance from here. It was easy to use a marker, knife, and scissors to make whatever sheet with a hole in it I needed.

Here’s the upper side install of the new horns!

And from the inside, after the fitting was crunk and the jam nut tightened!

This operation occurred synchronously with re-installing the “Hello I am a large truck of some sort” lights – I purchased brand new Truck-Lite Model 25 series units to replace the old faded and weathered ones.

Pictured ahead: The “portable shop” van of a friend who makes the best of having large metal object hobbies without a permanent parking spot, or a Big Chuck’s Auto Body. A shop van in my van shop, you say!

I decided to not reinstall the tacky single bulb holder in the “Courtesy i am a pimp van Lights “, but instead just bonded a segment of the “Ice Blue” LED strips to the existing baseplate. This would give a more even glow with the white plastic diffuser over it.

It does look good, but I wish it were more Miku-colored and less very high color temperature white – these Ice Blue leds are really just white LEDs with a purposefully skewed phosphor mix to make them emit like a blue star.

Maybe some time I will come back here and run more 5-wire RGBW cable so I can have varying colors!

The handles are next to be remounted, again with a custom-cut EPDM gasket on the the underside.

I’m now quickly reaching where the interior roof panels had to go back in. Here’s where I decided to divert quickly and make a more permanent mount for the roof console, one that is possibly removable or *gasp* serviceable later. I found which 4 holes were originally used to hold the shitty wood screws, and drilled them out for #8 sized tee-nuts for wood, then pounded them in from the backside. Not as secure as rivet nuts, perhaps, but it’ll do for now!

Operations moved outside the next day as the shop van friend committee was borrowing the garage for their own vehicle shenanigans. I’m definitely happy that I labeled every side and every screw that came out of these panels, because they really do fit on one-way only; all of the screws were drilled-in-place #BuildToPrint

After a few hours, we’re back inside to finish installation of the interior plastic trim and window frames. I decided spuriously one day that these should all be repainted in black bedliner. The motivation was more to have them all a uniform, deterministic color instead of shades of decaying gray and beige. I think they turned out quite well – the conversion window frames were painted first, then I decided to continue and also paint up the OEM van interior panel pieces.

There’s some lower trim pieces that I left gray simply because at the time they took more effort to remove; this is what we call “High production value”. Maybe I’ll do those later!

More post-painted trim pieces are going back in, as well as final cable pulls through the center mouse hole.

The shop van is lurking in the background – yes, we stuffed both of these damn things inside Big Chuck’s Auto Body for a while. Vantruck’s bed is behind me on stands in this photo, taking up the personnel entrance doorway. There was very little room to do stuff in this state! Luckily, they only needed the garage for a few days.

I somehow neglected to take any more photos of the center console, so here’s the only poorly-lit and exposed one I have. It now attaches using four #8-32 bolts into the tee-nuts I installed earlier. Since this photo, I’ve removed and reinstalled it a half dozen times to add or change things, so I know this worked out swell!

Alright, so this thing is still just a frame and hoses in the back. Before I put the bed back on, I still needed to do a bit of mechanical work. This included running some new fuel hoses where I thought the existing ones were rigid and beginning to dry rot, and replacing both fuel filler neck vent houses (which were DEFINITELY rigid and dry rotted).

Next, I decided to mount the new spare step bumper that I bought at a steep discount a long time ago (the vendor’s logic being who the hell else would buy it from them ever again? I can’t argue.) – the gray one that has been seen on Vantruck previously is slightly bent on one side due to jack-knifing the #VapeTrailer in the dark just a little too hard. As long as I’m going to this much effort to make it look good, why put the bent and slightly rusty one back on!?

It now gets to be the spare, and I emptied a can of black bedliner onto this one beforehand to unify the color scheme.

#OSHACrane is called to action once more to plop the bed back on the rails.

In re-mounting the running boards, I decided to address the galvanic corrosion issue by using Armor-Coat bolts in conjunction with fully isolating the aluminum from the steel mounts using some plastic strips in between. Because I am a millennial hipster, and would have had to go out and purchase something to make plastic strips from, I just spent a few minutes in CAD and then had the Markforged Army spit out a bunch overnight. What a world we live in?

While these finishing steps were happening, I was out scouting the Craigslists for two things that I’ve wanted but never went to the energy of getting, but the time is nigh after the thing is now a uniform color and pattern a.k.a the “It looks nice now, so you HAVE to” stage of affairs.

First is a bed-mounted toolbox, so I can actually carry a “crash cart” of service tools and fluids without them being a pile under the sofa bed, and second was a bed liner insert. I never quite got into the idea of spray-in bedliners. Instead, I was able to locate these big plastic kiddie-pool inserts  and went to pick one up.  The plastic bucket inserts do permit me to not do any prep work or cleanup work on the interior of the bed itself, but over time they can trap moisture and cause rust issues. Well, I’ll burn that bridge when I get there.

The story of vantruckstops here for a little while. It was the last weekend of July, and I was targeting completion by this time in order to hit up two shows: one was the Van Nationals over in western Massachusetts, because I figured if there was any place it belonged show-wise, it was there… and the other one was the Regular Car Reviews meet in Pennsylvania! Last year (which is insane that it was only last year!) we filmed the RCR episode which at this point stands at over 400,000 views, so this year I was aiming to hit both of these events as they were on the same weekend!

So here we are on July 27th at the Van Nationals event. The visuals won’t change much from here, as I only have some of the interior to complete and lights to add to the running boards. The bed isn’t painted yet – I decided to let my credit card rest a while before continuing on here. This will be something I hit either while visiting Atlanta again for Dragon Con, or afterwards in the fall.

The stainless steel caps were a hare-brained purchase following a recommendation. Short of actually getting polished aluminum wheels (e.g. Alcoas and Alco-alikes) which take work to keep looking nice, these “simulator” hubcaps improve the appearance over the regular painted gray wheels substantially… again, “It looks nice now, so you HAVE to”.

I discovered they come in varying levels of cheesiness, though, and I of course got the cheesiest grade possible to see how bad they could be. These have plastic retaining rings with a metal insert, which feels less than secure to me but probably are fine. More expensive ones are all steel construction. I can’t see pulling these off more than once without causing damage to the retaining rings, for instance. Aluminum polished wheels are an “Eventually” item.

 

I bounded south from Greenfield, MA around 6pm and encamped in Hamburg, PA that night, then rolled out to the RCR show! This event was quite a scorcher – the day was around 90 degrees and sunny. Coupled with the entire previous day of me wandering around the Van Nationals show and I was decidedly darker and sensitive to the touch when I came back from it all.

Next and last up, the final few addenda to complete the project and then we’re back to ROBOTS!

Operation RESTORING BROWN: The Paintening

And we return again! In the intervening hiatus, I (obviously) finished everything up and already went to Dragon Con with it. Yes, that Dragon Con.

The one that’s 1,100 miles away, with a vanbeast that gets 10 miles of gallon when it feels like. So, how’s the company doing lately now that you subsidized the Texas economy with the seed round?!

Links to previous tales:

  1. Episode 1 – the initial teardown of the house of horrors
  2. Episode 2 – Welding and repairing the major roof seam holes
  3. Episode 3 – Wrapping up electrical loose ends, some times literally

When we last left off, I’d basically run out of excuses to not start repainting it, short of trying to install 4WD and a turbo 7.3 diesel. But the real story is during the last week of June, I started mentally preparing by getting some samples of automotive paint systems on eBay (where else… you wanted me to actually walk into a PPG or Sherwin Williams auto paint dealer?!)… and this bullshit:

Yeah, that’s not a tool you’re supposed to paint vehicles with. But I maintain that since vantruck is the size of a shed, so shall it be painted like a shed. I actually based this decision on some friends’ and internet strangers’ anecdotal experiences about improperly painting cars. I figured it can’t be too bad, and the prospect of buying enough equipment to feed a proper HVLP pneumatic sprayer was declared out of scope.

Plus, I’m a sucker for experimentation, and if this $89 device will return even reasonable results, it could be pretty valuable for anything else I feel like repainting.

So these things if you’ve not seen them are called “airless” paint guns – they’re not truly airless, but what it means is you don’t have to use a separate compressor and HVLP regulator. Instead, they’re basically Shopvacs run backwards – the centrifugal compressor in a vacuum cleaner to generate a lot of suction pressure also shoots out pressurized air, and this (on the order of 5-10psi or so) is fed into a traditional paint gun front end.

The first cancer buckets I received were from the ebay seller “autopaintpro”. Very pro, indeed, I’m sure (So pro their actual website is almost completely broken). With a little research, it seems like they, and several other online auto paint sellers, sell a rebranded Autobahn/CPS system.

This was when I found out that auto paint is actually very runny, almost watery in consistency. A lot of these airless sprayers are advertised as being able to spray unthinned house paints and coatings. I suspected this was going to get very interesting. By the way, the actual color I’m using for white is Ford YZ “Oxford White” and UA “Ebony Black”.

My first victim will be the sun visor, which is a pretty large plastic/fiberglass piece. I went over the accumulated grunge sections with a wire wheel and gave the painted upper surface a gentle sanding (which really just made a lot of the old deteriorated paint crumble off… Great!), then cleaned it all with acetone.

 

The bottom side will get the inaugural paint gun salute, since it’s the least visible!

And then… we fire.

Okay, full throttle on this paint gun… no, this paint-cannon is completely unusable – it’s far too aggressive for the runny auto paint, and I found this out too late so just had to start waving the thing like a madman to prevent the paint from accumulating – not too successfully.

The finish is pretty horrible – the large droplets just formed blobs and very coarse orange-peel.

That’s gonna be a yikes from me, but at least nobody’s really looking at this thing, right!?

The next day, I came back to do the clearcoat, which was also as watery-thin and hard to control. I didn’t have a good feel for the trigger/valve force yet so I kept going way too hard. This caused a lot of running in the clear coat and even some entrained air bubbles.

Well, after dumping almost the entire quart of paint kit into just this visor, I decided to take a few days break to mentally size up the situation, wrap up the electricals and last bits of bodywork, and most importantly…

…it was time to split the thing in half again.  I was going to handle the bed and cab in two separate painting events. As you can see, Centurion themselves didn’t even try to do the rear of the cab at all! Y’all people paid money for this?

 

Nor did Ford bother with the front of the bed, which is left bare galvanized steel. Because who’s gonna look there besides me!? What this meant, fortunately, was two more surfaces – especially broad vertical ones – I could mess up on and practice the sprayer upon – where nobody will ever know my shame.

I bribed some friends to give an all-around sanding to the cab and bed while I continued working on electricals and removal of the side steps. To properly treat spray the bottom edges of the cab, and if I wanted to remove the front fender flares to paint them correctly, those steps had to come off.

I had to resort to Advanced Fastener Removal countermeasures for all of the bolts holding the steps on. Years of galvanic corrosion at the stainless steel carriage bolt to aluminum step interface meant the square carriage holes were completely turned to dust. I ended up cutting flat-head drive spots into all of the carriage bolts so I could hold on to them with a flathead screwdriver while impact wrenching the nuts off on the underside.

 

The van seam was also fully cleaned up/sanded, and I began priming all of the “Bondo Lawns” and other repaired areas. My plan was to paint the seam trim piece separately and ensure this whole area has paint coverage before putting the trim back on. The way they did it originally, the trim was screwed in and just blasted over, leaving bare metal underneath which caused rust to build up.

 

The cab endcap itself had a few chips and holes from what looks like attachment points for accessories which haven’t been there for years, so I also went ahead and filled those in.

The front of the truck bed will serve as my next practice piece. I sprayed a few piece of plywood in the intervening days, to make sure I got a feel for how little trigger was needed to get spray patterns I saw in Youtube videos from real car painting enthusiasts.

The answer was ridiculous, like 25% trigger or less. I almost contemplated making a spacer so I couldn’t get too trigger happy!

The second sample of paint from eBay seller “mbiauto” arrived, and I get to see if they’re even remotely the same color! This is a “premixed” i.e. pre-thinned paint, advertised as ready-to-spray. You typically have mix it yourself – that is, the paint kit comes with a gallon of base coat color and a gallon of thinner. I allowed myself to get ripped off slightly for this value-added service since I’d probably go back to them for top-offs in case I run low.

This adventure’s getting much better. I was able to make it act much more like an overpowered spraypaint can and get much more uniform deposition.

I tried all of the ‘beam angles’ to get a feel for how the thing behaves. This pass was done using the nozzle shooting a horizontal line, and moving it up and down. You can still see some discrete stripes from only making one recent pass – this effect’s called “tiger striping” as I discovered.

 

Well, I’m now confident enough in my technique to make more “production” parts. It’s helpful to have so many little attachments you can remove and work on individually! I decided to paint the front fender flares next. To do this, they first had to be removed and cleaned up.

The same Advanced Fastener Removal techniques had to be busted out here, since these things are almost directly in the path of all road spray.

The bottom sides were very thick with road grunge, necessitating busting out the wire brush and the RED brake cleaner. This is a substance even I, grabber of unnatural substances, refuse to touch without gloves. I’m in fact surprised that “Wannabe California #3” (a.k.a. Massachusetts) hasn’t banned it outright yet. I’m literally thick-skinned and it’s the only chemical which has given me skin rashes.

Some more curious manufacturer’s marks found when all of the buildup had been scraped off!

I couldn’t really hang anything up here in Big Chuck’s Auto Body, so I decided to also paint my jackstands.

One of my mistakes with the visor was leaving it on the ground, where some of the excessive paint ended up pooling and really causing some bad ridging as it dried that I then had to go back over and sand off.

These came out a lot better. It probably helps that the fender surfaces are also slightly damaged and even a bit porous looking, helping the paint stick! Nonetheless I was able to blast both of them without dripping.

They’re supported by the inside attachment edge which (theoretically!) shouldn’t be visible once installed.

I then unloaded the last of this quart kit on the rear of the cab to practice the wide swaths that I’ll be doing soon. Now that I’m confident in the technique, I moved onto buttoning up all of the leftover bodywork kibbles and then… THE MASKENING.

Some of the door bottoms had been concerning me, and it would be pointless to paint over rust. I ground all of the surface remnants off – fortunately, discovering it is indeed all surface rust with minimal pitting. This area will probably see a lot more moisture in the future, so afterwards I applied a layer of POR-15 first before priming the area over.

All of the doors received some level of security with POR-15, as well as a few blasts of interior panel sealer up the rain drip holes. I also sanded and primed over a few more dents and spots showing some surface rust in the front sheet metal, where it doubtlessly had been collecting bugs and rocks for 30 years.

 

Also for the first time ever, I removed the front bumper, so I finally have a good look at the way it’s attached for when the “front cow destroying empennage” is designed.

 

With all of these remaining items finished, I began on the MOST. FRUSTRATING. MOST HORRIBLE. I’M NEVER DOING THIS AGAIN stage of painting: masking off areas.

This is the one step that really is going to make me never paint a car again. It was basically an entire day of work just to mask things, and manipulating drop cloths and cutting pieces to shape. By entire day, I really meant almost 3 evenings!

I went for a “partial door jamb” arrangement in the end, since there are a few areas which I primed over that should be covered, but I did not want to remove so much of the interior (even more!) to fully paint up to the door jambs. So it’s really the  extruded surface outline of the doors up to where interior trim pieces begin.

 

And then…

 

There’s NO TURNING BACK B R O W N

This is after the first pass – it’s not very white yet, and the stripes are massive and obvious.

Second pass. There’s now a much more even coat, though some spots are still a little light and the dark primer and previous color still show a little.

Final pass – really just hitting sections individually. It was hard to gauge spraying white on white in a white-walled shop with not all that good lighting, at night, so I know there’s imperfections, but hey… who am I paying to do this again? Oh, that’s right.

After a day of rest, it was MORE. MASKING TIME.  I got some help spotting the laying of the masking tape for the black window outline, since getting this off-kilter would have looked hilarious.

I ended up selecting the outline boundaries based on 3 criteria:

  • To follow existing body creases and lines, and
  • Utilize as many windowlines as possible, and
  • …..hide the rust repair job done on the windshield frame and roof rain gutters

Really the last one. So, the black outline is a lot less aggressive than one of the original concepts I posted here. This final layout uses all of the windows bottoms except the driver’s side conversion van windows (which will dip down) as guidelines, and incorporates the rain gutters entirely instead of stopping under them.

As I said before, I painted the ‘Frankenstein stitch’ van seam trim piece separately. With the black outline now about to go on, this is when I screwed it back on. I’ll just be masking around it in a contour.

The rest of the cab is now draped off with drop cloths, so it’s now time for….

when you go black, you don't go back, the followup album to no turning back b r o w n.

Yeah, so this entire other day of setup ended up just taking 15 minutes to spray. Hey, not bad looking so far!

The endcap curve was a little hard to get right, so I used some color-matching touchup spraypaint to make some little changes here.

 

The following day, I set up both fenders and the cab to hose down with clearcoat. I went completely overkill with the clear for sure, and it was very difficult to visualize when spraying. As a result, there are a couple of runs of clearcoat on the cab – but it’s very hard to see unless there is direct overhead sunlight to expose their refraction and shadow.

I made sure to stand up on my stepladder to absolutely drench the roof – I wanted this area to last a long time, and nobody will ever see the finish being rough. The roof was also where I ended up dumping the rest of the white base coat too.

Oh yeah, while I had black still hanging out in the paint cannon, I decided to actually spray the underside of the fender flares – otherwise they were an awkward raw resin color and would be very visible from the outside.

And after the great shedding of the masking tape and drop cloths… Not bad, honestly. Did I mention how I’m never doing this again!? In fact, at this point I decided that doing the bed was a canned enough exercise that I was going to tap out, and hand it off to my van salon. Imagine that, paying money to have a service done by professionals in the trade.

Up next: The great reassembly, and tales of other little kibbles that got left out of this main narrative!
