I did have some questions on the axle bushings. I'm curious about the specs for clearance. Both dropped out and and have a loose fit on the shaft and housing bore. Are they intended to just float? From what I read it seems that they should have been a press fit in the housing.
Gary,
I have a good crop of "helpers" this year. All of the kids working on the M37 are 2nd year students and almost all of them are enthusiastic and have come to really enjoy wrenching. The M37 is turning out to be a great project for us. It's going to be much more costly than expected, but it is a great teaching tool. No cheap plastic bits to break, no funky hardware, TONS of opportunities for projects, big durable nuts/bolts, and a bit of a history lesson
