Is that 1/8'' plate you weld to the rockers when you attatch the body to the frame?
If you get a chance to answer these questions i would be very greatful, thank you.

PS, im a huge fan of what you guys do and how you do it. Definately outside the box.

We just cut out the floor and start with the base rails, Every car is different as far as engine location, so you deal with a lot of different lay out issues, Like the oil pan problem we are having in attaching the tubing to the slugs we put in the crossmember. We only use the computer to set up the suspension geometry and then design all the pick up points tabs in Solidworks, so we can water jet them, which will come soon.

Yes we weld 1/8" plate to the rockers at that time we also shave the pinch weld to get the car just a tick lower.

We joined the X'x next to the tube and not pointing them directly in the middle, we set it just next to the joint to put the welds almost on top of each other. It would take more time to double notch the X's. We do that on the higher end builds this way make the floor a little easier. The goal of this build is to build a solid, well bulilt chassis on a more reasonable budget. Corners have to be cut some where or all the builds would end at millions of dollars.

We got the rails set in tonight before I left and they looked awesome.

Work... Frame Rails....

Rodger,

Are you implying that you actually leave the shop? WOW..... I thought you lived there!

This build is really looking good!

I'll be out there in a week. I need to coordinate with John one of these days to be there at the same time.

Yeah I came home at 7pm tonight.

Rodger

I thought you were using a CNC bender........dont you have one or one of your buddies has one???

No CNC bender. Just digital degree Ercolina, I dont have that kinda dough. I bought an Eagle tubing roller a few months ago to roller te different radius's we want. But that thing is my no means an exact science, it take time a patience to get 2 tubes the same.

Rodger

So some rear frame rail pics. They look awesome, We plan to plate them in and add lightning holes and then build the tubs before we weld the rails to the chassis. other wise you could not fit them in afterwards.

Today I also figued out that I can run my 8.5 - 9.0 front rims. We got the suspension mocked up and figured out we can fit a 2 inch wider track width. So we widened the Crossmember and will reinstall it monday along with orderng the rack to go with the front end. MAN this is a tight car to fit stuff in.

Enjoy

Looking really nice - I can't watch this one

nice work as usual. I think it's cool that you are posting the $$$ side of things as well.
