1/12th Scale 1969 Camaro Build

[black2002ls]

Have you considered using xtc epoxy over your 3d printed parts so you can get a smoother surface?

I'm not familiar with it. Is it a self leveling epoxy?

Some of the more rough parts, I ordered that way intentionally to retain the cast/textured look. I think I am going to go at the whipple with a fine grit paper and smooth out a few areas of it.

I'm trying to convince myself that reducing the amount of detail is in my best interest to get this thing finished. Trying to be realistic about what is going to be seen when it is in the engine bay with all of the other details. Do I need this bolt, or that bolt, will the texture be seen? If it is seen will it be noticeable and if so, how out of scale or unrealistic is it?

After this thing is done I've got 3 1/12th scale Mustangs, a 1/12th scale S-10, and a truck load of 1/24-25th scale stuff that is all mid project.

I love this thread. Nice work!

Thanks. It is about to get real interesting. I'll be ordering a bunch of machined bolts and a/n fittings later this week, once I get all of the sizes sorted out. I used to have a conversion list that had all of the sizes needed for 1/12th scale on it, however, over the years it got misplaced.

man, this is a true labor of love. i would have wadded this whole damn thing up 100x's by now! looks killer brother!

god bless.

You have no idea how many times it has either almost made it to ebay, garage sale, or just trashed all together!

Put some color on the whipple this evening. The color on the body is burnt iron, magnesium on the TB and the backplate, semi gloss black on the pullies. I added some machined aluminum bolts the the back plate. Lots of detail still to add, but it is a start.

Due to this being a single unit, the fuel rails, injectors, and TB will be used and detailed. The only way to really super detail this thing would be for it to be printed in multiple pieces, or to cut it up. I feel that with some wiring, fittings, and paint it will ve convincing once it is nestled into its home. I will be adding some more detail to the TB to look like a DBW unit.

Well, a box of goodies showed up today! Whipple, TKO500, bell housing, and other misc goodies. I should have consulted with Ron on the bell housing. The mounting flange on the T5 doesn't match the bell housing, but that is an easy fix! The whipple is a very nice piece and the conical air filter mates right up. I will probably remove the fuel rails and injectors and create my own. I need to pull a few refence photos, it looks like the way the whipple is going to sit, I may need to scratch up a valley cover for the LS. Time to start counting for machined bolts and goodies!

Not a huge update, but figured I would chronicle some of the growing pains.

Moving to the smaller wheel means I need to change the size of the brakes that I drew up in Solid Works. I'm hoping to be able to accomplish this in the shapeways terminal and not have to completely re-draw parts.

Here are a couple of shots of the wheel size that I will be using. The aluminum ring has the same ID and OD as the printed sleeves, and of course a shot with the brakes behind the current wheels.





Hopefully I can find the time to scale the brakes this weekend and order some test prints to make sure that everything fits correctly after the changes.

You can really see the printing process on this wheel center. This was a prototype print in a cheap material to check size, fit, and design. I have scaled down the "big" wheel to the same diameter as this wheel, so hopefully the spokes come out a bit thicker when I get the test prints.

Well. It rained most of the night and morning here which means it is too dang humid to work outside. Sooooo. What do you do while the wife and kid take a nap. Work on a model! I got the CF finished up on the main body. Jist need a little black touch up then I can clear it. I picked up one of Ron's LS motors. Unfortunately I cheaped out and got WSF instead of FUD. It is quite grainy. I'm OK with the block. It has a cast look to it. I hit the oil pan with some 400 paper and then testers magnesium metallizer. The block is generic aluminum. With a matte coat. I need to order heads and valve covers in FUD. I also put a second coat of chrome on the wheel sleeve and hit the center with Tamiya gunmetal.

Tldr

Scale wheels hard to find.
Multiple attempts to create my own. Finally found solution

I'm not sure if this was chonicled in this thread, but the wheels for this thing have been a huge problem from the start. 2 different attempts at scratch building wheel centers. Zero luck finding someone to machine wheel sleeves. Then came 3d printing. I designed some wheels, and sleeves. Printed some tests and decided they were on the small side. So, I re designed them printed them, BINGO. Then I find a guy capable of machining sleeves, though in the end tjey didn't turn out like I wanted and decided they were ultimately too big. Back to the drawing board.

Somewhere along the lines I had a buddy out in California send me some tires that he had molded and cast. I got to fiddling with the original prints that I thought were too small and decided that I liked the look. Next step was finding a suitable finish for the sleeves. Either mimicking an aluminum finish (polished, maybe brushed) or chrome. Well, along comes molotov chrome paint pens. People are getting pretty convincing results with them. So, I gave it a shot on my test prints. I smoothed the sleeves out a bit and hit it with the chrome. I didn't spend enough time getting the sleeves smooth as glass since it was just a test. But, I think I've solved the problem that has plagued this build for the last decade....

Hell yes! Let me know

I'm not familiar with the specifics, prices have probably come down since I created my first parts. The other part of it is not being really proficient modelling stuff in 3D.

Here is the kind of detail I am after

I think I might be able to do that on my machine. My machine is fucking gigantic, but it can do somewhat impressive small stuff. I'll download an STL if I get a chance and shrink it down to that size.

[black2002ls]

Damn.

The guy that designed it has internals available as well. If it wasn't so damb expensive, I'd build a 1/4 scale LS1 diorama
