View Full Version : New foam projects: VW Thing and Renault Galion

First up, a 1960 Renault Galion heavy truck. I wanted something to haul my RC rock crawlers around, and it had to be a cabover to maximize bed space. The Galion is ugly and unique enough for me to build, and has enough curves to be challenging. It's built up from Depron foam sheets. The roof pretty much defines how much the foam will bend without cracking.

Like the weathered finish? It's easy. Paint the rust first, then sand through the blue til you get the desired effect.

Next up, a VW Type 181 "Thing". There are no curves in this one, so it went together fairly quickly. However, the scoops, fender lips, and various other details (the ribs on the body will take a while) are going to take some time.

The headlights are from a Tamiya Blitzer Beetle RC car, and are the only body parts I didn't make myself.

Taillights are carved from pink house-insulation foam. I'm going to use a lot more of this stuff 1thumbup1

An overall shot. It may not be perfect 1/8 scale, as it's tailored to the Frog chassis. HPI Wheels and Tamiya BFGoodrich tires are narrowed approximately 1/4 inch, and the front wheels have been modified to accept bearings.

And I still have another sheet of foam. I'm not sure what's in store, but it could be a Lincoln Mk. V.

Looking good so far. I'd like to see what you do with the Lincoln.

Oh boy. more eye candy from OBH....great stuff buddy.
I can't take on any more projects at the moment but you've got me thinking, I will eventually tackle a 1/6th boat and I'm leaning toward doing the hull with foam, I know enough not to use adhesives or paints that will attack the foam but (if you have the time) how about a few tips on what you use as far as tools, advises, primers, paint etc. goes. It might keep me out of the psycho ward a while longer. 1wack1

Any info on new and different materials is always welcome.

The foam itself is the Depron that electric-airplane guys use to build "foamies". It's available from Midwest Products under the trade name Cellfoam 88. Most hobby shops should be able to get it.

Adhesives: Only foam-safe CA glue was used in these builds, but hot glue also works. Use an accelerator with the CA. Regular CA will eat the foam.

Once the foam panels have been glued and the sanding has been done, just paint it with 20-minute epoxy mixed with Microballoons filler to make the cured resin easier to sand. Let it dry overnight. The epoxy will fill in any panel lines you cut, so make them deeper and wider than you think you should. You'll probably need two coats of epoxy to get a good smooth finish, and since the epoxy is semi-liquid, you can only do one side per day.

We can always count on OBH to have something new. Personally Ive never messed with the foam. Just how tough is it after your all done?

Don Garrett
06-09-07, 05:26 AM
You can get foam in different densities.....10lb. can be worked and shaped with hand tools...if you go all the way up to 40lb. or more it can be used for CNC machining masters or models. The higher the lb. number the "harder" the foam. The denser stuff will hold sharp lines and fine detail. It comes in sheets or blocks (I think you can get it around 20" thick).

Old Busted Hotness
06-09-07, 08:38 AM
The stuff I use is pretty lightweight. Don't know the density #, but it's low or the airplane guys wouldn't use it. Once it's got epoxy on both sides, and the windows in, it's tough enough to withstand a rollover of an 8-pound truck. I drive this one all the time:

Notice the dirt on the corners of the roof. It's as durable as a typical plastic-model body.

And it's not just bodies you can make with this stuff. Get the pink stuff at Home Depot and you can carve engine blocks, manifolds, seats, any shape you can think of (and execute).

06-09-07, 01:26 PM
If I go to Home Depot for the stuff, what do I ask for? Is it the same name Cellfoam 88? I want to make a master buck for my 49 Caddy body and I didn't want to use wood. I also want to soften some styrene sheet and mold it over the buck to make the body. What density should I use and is Home Depot a good place to go for the stuff besides Midwest? Thanks in advance.

I think I've seen that stuff at Michael's also..

Old Busted Hotness
06-09-07, 05:01 PM
You have to get Cellfoam from your LHS, it's sold in 1x4 sheets, 3,5 or 10mm thick. Home Depot has the pink foam used for insulation. I'm pretty sure it comes in 4x8 sheets, 4 inches thick. I used a scrap from a mal-formed airplane wing. I'll see if there's still enough printing on it to get you a trade name. Since it's pink, I'm inclined to think it's Owens-Corning.

EDIT: definitely Owens-Corning, but that's all the writing I could make out.

Jeff......if you are going to do a body....a good place to start would be RenFoam, (although there are other choices)....it's more expensive than hardwood but I really like the stuff. If you can't find what you want, give me a yell.

Gotcha.That sounds great. I think that stuff would be much better for me that trying to use hardwood. Thanks guys.1thumbup1 1thumbup1 1thumbup1

Here's how you turn Ford hubcaps into VW hubcaps:

Press the VW emblem into the shiny side of some aluminum foil, so it makes a reverse image, then dump some epoxy on the dull side. Once it's dry, you've got some nice reverse-image VW logos that you can fit into the centers of your hubcaps, after filling in the Ford Deluxe emblems. I'll cover them with Bare-Metal to hide the putty.

06-11-07, 08:22 PM
That's a great tip. I'm going to try with some other hub cap brands.

Old Busted Hotness
06-11-07, 10:00 PM
Note that it only works on symmetrical logos, or logos that are raised. The VW logo is in relief on the hubcap, like so:

http://www.scalemotorcars.com/forum/images/imported/2007/06/26.jpg

You can see how I made them, by copying the logo from the shiny side of the foil, to get a relieved image. This will produce a backwards logo, which isn't a problem with the VW roundel, but most other makes could have some funky issues.

Cut 'em out and bore a hole in your Ford hubcap: I used a Dremel with a grinding stone.

http://www.scalemotorcars.com/forum/images/imported/2007/06/27.jpg

After a little Bare-Metal over the putty covering the Ford script, they're ready to mount up. I like 'em 1thumbup1 (although the foil could be a little closer match to the chrome)

Looks like a winner to me. Now to figure out how to get around the symmetrical thing. Wait, I think I have a solution. Take a piece of styrene and form it in the shape of a hubcap with no writing. With magnification, a Dremel with a small bur and some good sharp instruments, cut the hubcap design into the styrene. Then, you can make a mold and make some resin caps and cover them with BMF. It's worth an experiment. For the deuce, I'm building, I'll be making some Fiesta hubcaps so I'll be experimenting with a few others.

For a master, save yourself a bunch of time and use a plastic Easter egg. They have a great dome shape and only need the logo etched in.

OBH the rims on your VW thing in the above image look interesting. Any information on them?

The rims are from the Tamiya Frog RC kit. I'll see if I can find some pics, or take some for ya. OD is 1.5 inches.

Don Garrett
06-12-07, 04:44 PM
This cracks me up...I had frog legs last nite (fried) breaded in corn meal. Didn't know Tamiya made an R/C "Frog"....how do you prepare them? Okay...I'll go stand in the corner.

Old Busted Hotness
06-13-07, 07:07 AM
They originally released the Frog in 1983, and called it that because the rear suspension resembles frogs legs, if you use your imaginaltion. Then they molded the chassis in green, and to continue the theme, suggested a white and pink 2thud2 paint scheme. Really, how you gonna figure them out? The Frog's body is a typical single-seat racing buggy, so it's ripe for replacement. Tamiya re-released the Frog last year along with a few other vintage (and animal-themed) RC kits, the Hornet and Grasshopper. And now, because you've all gone to sleep, here's the skinny on the wheels:

Frog wheels come in two varieties: front and rear. Fronts are skinny and rears are way fat. Both come in three pieces, a center section to retain the bearing (front) or drive axle (rear) and provide a beadlock when the other two sections are screwed on. Since I modified all my rears, I don't have any pics of unmolested rears (you just shut it, Grandpa) but here's a front for ya.

EDIT: found a rear, but my admonition to Grandpa stands he1he

At 1.5 inches OD, they'd be marginally useful to us. What we really want are the long-discontinued Rough Rider wheels, 1.7 inches OD. But they haven't made those since ~1980.

Old Busted Hotness
06-13-07, 07:11 AM
And I did make a little progress on the Thing, as well. The body is at the point of diminshing marginal returns as far as sanding goes, so as soon as my turn signals arrive (from another board, they're coming from a Lexan Bug body) it'll be ready for paint.

That's really starting to look great, OBH.

I can't believe Don went into the corner. And all over a portion of frogs legs. I can just see all those unfortunate little frogs in little tiny wheelchairs wheeling around all over the floor. he1he he1he he1he

That's an easy one: Tamiya Sand Rover. Well, not so easy to find, it's another vintage kit, pretty highly prized by collectors:

http://www.scale4x4rc.org/forums/showthread.php?t=6546

In typical Tamiya fashion it's listed as 1/10, but it's closer to 1/9 scale.

Here's a pic of the Meyers Manx Tow'd, they only made about 850 of 'em...it was an attempt to foil all the copy cat bodies that were being made at the time of the Manx. The Manx SR (street roadster) was my favorite. Belive it or not Manx bodies sold "new" for about $600 back then.

Got some paint on it, and made a license plate with the ACME license plate maker (link is on my other computer if anyone doesn't have it)

I'll take a pic of the plate in a bit. The paint turned out pretty well. I don't remember plain old Testors yellow being this bright, but I'll take it.
