truck, boat, and trailer


Recommended Posts

Got the wood done on the Chevy, and applied a couple coats of satin spar varnish.  Put a couple coats of Mr. Color gloss clear coat on the paint.  Needs to be wet sanded and rubbed on the paint yet, and some BMF around the windshield frame and vent windows.  Found a set of wheels and tires in the parts box, that I’ll paint either brown or gold to match the body.  Going to paint the uptop, boot cover, and interior a deep burgundy, then on to all three engines for the car and boat together.

Really nice- I like your pick for the interior color-one of my favorites! Are you thinking of doing the boat to match?

Thanks Paul!  Yes, the boat will have the same interior as the car.  The rear deck cover and fin will be painted the same gold as the hood on the car.

Well, it’s been a while since my last update.  Now that Paul has finished his amazing combination, I guess it’s been left up to me to carry on this thread, and I am a notoriously slow builder, so the updates sometimes are spread out quite a bit.

Since my last update, I have finished the wood, and the paint on the body for the Chevy, and painted the interior and top.  The pics here show the car still in mockup with different wheels and tires than I will ultimately be using.CD20992A-B034-4044-A881-713D25EDA8BD.thumb.jpeg.d23d1e5e5b89b08eeb6ab792ae7309e6.jpeg5805EA47-2423-45D4-AF28-01DC48A18577.thumb.jpeg.76577b4f7a475f1db5653c4d48cbee7c.jpeg  This pic shows the wheel/tire combo that I intend to use.  9CDAB4D0-BE06-4893-873C-AE21B8A30461.thumb.jpeg.2177f826ded7dc81653881cfb1709f14.jpegI still haven’t done anything with the engines other than to rough one of them together to check fitment in the car and boat, but they will be coming soon.

I decided to turn a little attention back to the boat, and more specifically the engine cover and rear fin.  The Dumas kit just provides two pieces of balsa wood and says to glue them together and sand them to shape for the engine cover, and another piece for the fin. 6096EFEB-2C82-4CF8-9C92-ECBFB46DF421.thumb.jpeg.ec48ce3601d73a45f486376ae80727b0.jpegAEA791DA-B649-43C9-9D41-BE1F14D41430.thumb.jpeg.851c2fd4c37dfd75c402d747942e0efc.jpeg6965E676-5068-4C6E-93D0-A5735449FD24.thumb.jpeg.46cbabb3ac922eab0183cd28c0371a2b.jpeg Since I am going to be detailing the engine bay, and adding two 3D printed LS3 V12s, I decided I want to make a engine cover out of plastic, with hinged hatches that open up to reveal the two engines.  I thought about making a rubber mold and casting it in resin using the balsa piece as a form, but I don’t have much experience with that, so I thought I’d try vacuuforming, mainly because I have some stuff to do that with.543AD90A-AA33-4182-83CF-8B14705C0AB2.thumb.jpeg.9af72c9572bfe0268e7377279b0e8dfc.jpeg

I didn’t have any styrene on hand, so on my first attempt, I used a piece of PETG (acrylic Polycarbonate), which I use to make windows.  It is very hard, and strong, but does not sand well due to it’s hardness.  Unfortunately, the piece that I was using was too thick, and I think I had it too close to the heat elements in my oven, and it blistered badly, looking like obscure shower glass.  279D2669-745F-4EE3-A704-201A947C4FC7.thumb.jpeg.ef432a6afde071dc330fb7876ab2c5d4.jpegI thought about trying to sand it, but as I said, this stuff is very hard, and does not sand well.  I thought about spreading a coat of Bondo over it, but I think I’ll try again moving the next piece more central in the oven, and heating it slower.  If that doesn’t work, I’ll try using thinner stock, or getting a sheet of styrene, or both.  If none of those work, I can still go the resin casting route.  The good news is that the vacuum former worked well, and the plastic took the shape nicely, and it fits pretty well.  Ultimately, I’ll need to sand the buck a little smaller to allow for the thickness of the plastic, and the correct fitment.  E99368DF-CA9B-49A0-B58E-A1DFD0A9F5B3.thumb.jpeg.197b3e56ef97d1d98df3340d337cd7c9.jpeg

That will have to wait until tomorrow though, since it’s getting late, and I’m tired for now.

Later,

Great progress! Those fifties fins on boats were pretty wild! Looking forward to some engine mock ups too! Nevertried vacuum forming- I understand the process, but never gathered tools and materials to do it.

Tim...this is just so, so sweet!   Thx for keeping us in the loop as it comes together....TIM  

Thanks Guys!  I’ll keep on plugging away at it, even if it takes a while.

I’ve had some success with vacuum forming the tonneau cover and fin, out of styrene.  I’m pretty happy with how that came out, and I’ll cut hinged hatches into it for engine access, after I get a little further along with the engines, and get ready to install the cover.CCE6978C-503B-416B-ABB2-E22E620E496A.thumb.jpeg.e9db4a68567eaea9db9ad4d002922d9e.jpeg27D49B3E-24F9-4FF0-AEB1-5E22CE833A45.thumb.jpeg.9fbfdec6410bf3deae4b0abc182b107d.jpeg56AC290F-E5B8-4008-960B-BA2C55B6B38E.thumb.jpeg.7c3b63c2dc9802735377a4ebeb871b11.jpegDE94F816-2864-44AB-BF2A-9D30CD31F09B.thumb.jpeg.0880c996d894274118f2f47f83a155c2.jpeg8D2815EA-C9D8-40F9-ACBF-C83D03D6531D.thumb.jpeg.acfaccf1c325d524dd775ba263209c74.jpeg

Speaking of the engines, I have roughed together the two V12 LS3s, and roughed in the timbers where they will be mounted. So far, so good.AA551BB3-F38F-44E3-A580-658EEF1241A0.thumb.jpeg.c94518303d7483348b0d5fb18672cd48.jpeg9CE55E40-3B79-45AC-B3B2-42E87B74A3BE.thumb.jpeg.12faa0d29f6f0850fd60c307b7bb6933.jpeg

Very tasty work! The engines look particularly healthy! Wood work looks great and the finned cover came out really well. As always, looking forward to more!

Thanks Paul!  Not sure what I was thinking!  Not one, but two V12s, plus one in the tow car.  36 cylinders in all, with 36 fuel injectors to detail, 36 spark plug wires to run, 36 exhaust ports to fabricate.  This thing is going to take a while!

Magnificent brass work! Never did learn to solder- I assume you used a jig, then attached to the engine?

Thanks Paul!  I’ve been soldering brass since I was about ten years old, building slot car chassis to run on our local hobby shop track.  I generally don’t use jigs, although I probably would save myself a lot of headaches if I did.  These were all done freehand.

Now that the Power Wagon is finished, I've started back up on the big boat. I started putting in some ribs where they would be visible in the engine compartment, and made a start on the V-16 engine- by cutting off the cams, combustion chamber, and intake and exhaust ports- from two Monogram Duesenberg engines! My friend Alex had included a length of plastic rectangular tubing which will be perfect for the new cylinder banks- just needs to have the corners sharpened a bit. It's not styrene- tried a little liquid styrene cement and it didn't soften it at all. More pix when I get more done!

V-16 beginnings.jpg

The 1/25th scale Allison aircraft engine from AMT would make a killer engine in your speedboat, and the irony would be that the full size PT boats used TWO of them for power. I can remember in my teens going to a drag boat race on a local lake and one of them that really got my attention was a flatbottom that had an Allison in it for power. I don't think that they turned that monster much above 3,000 rpm's but with the torque it put out gearing to get some serious prop rpm wasn't a problem either. That thing did make some seriously different sounds than the high rpm V8's but it was wild watching it come practically completely clear of the water about mid course when the pilot got the nerve up to put the pedal all the way down.😮😛

Del....not to derail this thread but I did build an Allison-powered 1/25th scale boat some years ago....I think I did a how-to on this one for Model Cars mag back in the day. too....it was loosely based on the Rudy Ramos boat that ran in the Salton Sea 500 c. 1965 or so TB

Well, it’s taken a while , but I’m finally making some progress on my car, boat, trailer combo.  I punched some louvers in brass for the turtle deck, to let some air into those 24 injectors. I finally got the hard plumbing done for the wet exhaust, and the heat exchangers made up and mounted.   I also got the intake manifolds done.  What a pain it was, getting all 24 of those little shortie velocity stacks mounted and lined up!  Overall though, I’m pretty happy with the look.
