Finally found a place to get metal! About $100-125 for my 17ft of rectangular tubing to start the frame with. Hopefully I'll be able to pick it up on Friday. It's about time.

Not to scale, just to show body shape. NOT A STRUCTURAL PICTURE ;)

To scale front end sketch... Ugh, just noticed I wrote ten cubic inches instead of 5 SQUARE inches...:

Do threads ever get deleted if they become too long? If so, I'll start making a duplicate copy of this...

got my metal yesterday afternoon for the two main beams that connect the sub-frames, ended up being $75 for about 17 feet of the 2"x4" .120 wall. Couldn't be happier :)

Today I finally had some more progress. After the shop cleared out I stayed late to finish up the cuts on my main frame beams. Took a few pictures to show what it looks like just laying them on the ground.

and finally... somewhere down the road :shock:

Apparently the M60 weighs 6 lbs more than my m30 and gives me another 80hp in stock form, or... 420 more hp in this form :D

Got a 9/16" drill bit for the subframe mounts. currently fabricating the C-shaped pieces that will weld onto the end of the main side frame and attach to the subframe mounts. If the tolerances for the screws are too large, I might have to find a new bit or mill out the sizes on a lathe...

Hey, where do you go to school? I know some kids in the Marin area. I'm just on the other side of the Bay and I'm a senior too.

Cool. Also... I would get another rim to match at least the size of the other ones.

You should start drag racing up at Infineon. A lot of kids do it and it's really fun. Last year a good number of kids from Navato did it.

That wheel is the spare, I have the othe one cleaned up in my room. I know one or two kids from shop classes at COM, Tony and one othe kid whose name I can't remember right now. I've thought about drags, maybe in the future... I wish they had actual hot laps you could drive around the course

Yeah I'll probably do those when I get the chance but maybe I'll go to a drag or two for now. I have a couple friends that go too

Yesterday my friend helped Daniel me out; he has a shop and a TIG welder so the rear section of the main beams are welded as well as the C-clamp shaped subframe mounts. Tomorrow will be a test fit and any needed changes will be carried out.

Does anyone know the correct distance between the tops of the front struts? I cant seem to find the information anywhere and I need to make sure the camber is correct.

make the camber adjustable. 0-3 degrees negative should do it.

I shall, thanks for the tip. But i still need the OEM strut distance so I can keep them at the correct distance while I make the pipes that they mount to.

If I could walk I'd go outside and measure it for you, but perhaps someone else will be kind enough to help you out.

You probably should have measured that before you scrapped the car.

Today led to another visit to Daniel's shop and the completion of the rear section of the main beams. The C-brackets for the subframes are welded on and the test fit went well. All that's left for the two main beams is to drill the holes for the front subframe, get it angled, and weld the last two pieces on. Progress feels good.

Welding

Spence--Is "Daniel's" a welding shop that you are using? Where? I know a really cool machinist and welder in Tam Junction if you need one. He will take on any project and help out.

Those welds look very nice!!javascript:emoticon(':banana:')

"Daniel's" is my buddies welding shop of one :) He's my age, he's just been doing this stuff for years and is thus way more skilled than I could ever be. He was able to share a little shop space in San Rafael with another person and its where he is currently building an electric Honda dirtbike. But I will tell him you approve, I'm sure he'll be delighted to hear it!

Machinist

Post by nimbuzz »

Bay Metalfab -- Tom Carter -- he's behind Proof Lab
388 - 9777 It's kind of a hole in the wall place but Tom is skilled with reasonable prices -- Call him first--he might have a problem with metric sizes on his lathe.
