The BMW 507 Ultimate Build Thread!!!

I sure hope this turns out well. You're putting a lot of work into it.

Total rookie here but could you use spray foam?

[A12pilot]

Thanks, Freddie. I think it will. Crush, the spray foam would be a big mess, and carving this foam is a smaller big mess, so I decided on the smaller big mess.

Updates later this week! Coming together nicely! I think if things go well I may pop a body next month!

Moving forward, been doing some more sculpting and forming. This is just the initial go-around and I'll hit it with long boards after the body is foamed up. Starting to take shape! I’m extremely pleased!

Cheers

That looks great.

[Billohio]

What are you cutting it with? I would think that stuff could be everywhere

[A12pilot]

Bill, it’s cut with a 12” fine tooth sawzall blade and sculpted with a belt sander with 60 and 80 grit. After each day I clean the shop and surprisingly, it really doesn’t make the mess you’d think.

Coming along great. Have you done any measuring of the buck just to make sure it all matches up exactly with an original? Just curious since you're really into the meat of the body now, I'd be freaking if I found something was off after all the work was put into forming the mold.

[Hawkeye]

Looking great!! Once you have the entire car formed in wood and foam, what is the process to make a mold and how many sections will it be? Did you get your intake yet?

Thanks,
Marty

Marty, the owner of the intake was really cool to talk to. After considering what I needed to do, I just couldn’t justify that price for an intake I’d need to modify anyway. I decided tig welding two-barrel adapter plates to a dual-four intake would be best since I need to do some fabricating to the remainder of the intake anyway for a drip pan. I couldn’t justify bastardizing a vintage speed part like that. That guy builds some cool old-Skool hot rods!

Mark, I’ve been going off measurements from the model and then multiplying that number by 18 to get the proper dimensions. I have exact tail light housings and used this method to see how close I was to the actual real part. I was about 1/18th off, so it’s safe to say everything else is measuring correctly. Big dimensions like width, length, and wheel base are exact. Honestly, a keen visual eye for the detail of the curves is really all that’s needed for the forming of the panels. Smaller items like location of the side grilles measured perfectly.

I am thinking I may have the 3D scanning company come down and scan my completed buck and do a comparison to the scan of the model body and see where I may need to make any corrections. They can overlay one over top of the other and any resulting errors would show up red indicating where I’d need to trim.

More esplainin’ later.....
