Can anyone identify this frame for me? My next build will be a Speedster based on a 20s to early 30s Chevrolet. I was hoping this was a Chev frame, but the lack of a hump for the rear suspension has me stumped.
Chevy rails were straight (viewed from above), but had axle kick-ups at each end, at least the latest ones (c1930) during that period. I have a c1918 Buick frame that is similar to this (but not the same). This one looks like maybe the rear springs were attached to the frame at their front end, pivoted at the mid-point from the chassis, and attached to the axle at the back. I think some Bugatties were sprung this way. Unless your dead set on a Chevy frame, I think this would do perfectly. I'd use the front in the back, cut the frame before where you'ld like the rear axle to be, make a short curved transition piece to get higher but "natural" looking rear kick-up (as opposed to a hokey looking pie or mitre cut). Use a cross spring (Model T?) in the front.
May help if you take a close up pic of front frame horns and give height of frame ,overall length and width. That looks like a pretty big drop in the front cross member,maybe it;s just the pic.
I agree with you Desmodromic, this frame will do just fine for what I want. This build is probably not actually going to start until next fall, but the thought process is in full swing. I want to stay with Chevy style front springs. Thinking maybe quarter elliptic rear springs with the axles hanging out a little past the back of the frame. Yes Dan31, that front cross member is quite deep, will probably modify that some. I'll take more pictures when I get the chance.
A little more info on the mystery frame. It's 118 3/4 inches front spring mount to end offrame, 29 inches wide at front and 41 3/8 inches wide ar the rear, bottom of the cross member to top of frame is 9 1/4 inches. There is an aluminum tag riveted to the rear right hand side of the frame that reads: 90 CC 80743 What ever this went to had mechanical brakes, though there is no indication they went to the front wheels. Here are a few more pictures
Frame make solved. Was at a car show and saw a Willys Overland Speedster, 1916. It had exactly my frame, right down to location of manual brakes, rear suspension set up, measurements and VIN location. That's pretty cool, as a pre 1920s speedster was my plan all along.
