With all of the talk of torsion cars, I had to give one a try but I could not find enough brass locally so I built mine from wire. 055 center rails flanked by 047 with the rest being 039. I know the image is a little dark but I took it at night. I will be testing it tonight if the bearing glue ever dries. Damn cold weather. 54ef70474cb78d47edcf621ca2b33464.jpg

Chris, you didn't indicate what bearing glue you used, but you could apply a little heat from a hot soldering iron to speed up its air drying.

I just heat mine with a torch for a few seconds, it helps set the Loctite.

I put the bearings in with blue loctite and put it on the oil burner for 24 hours. Works every time. One note on the chassis I suggest using .063 uprights for the front axle mounts  for more strength. :)

Mike, I think I used 055 for the front uprights. The 039 was just for the structure.
I tested it last night, ran way better than I thought it would. Car is also heavy at 103.
