Started bracing last night and added image to this album:
https://imgur.com/a/DekcN2k The center cross member is temporary placed right now. I'm using 1"X1"x1/8" wall because that's what I have. The solid part of front axle is 1"x1.5"x1/8" wall for same reason. I can prob. get a piece of 1"x2"x1/8" wall for this if you think I should.
Was just browsing 2018 build rules from USLMRA and see that I'd need 8" rear rim.... I suppose at this point I can go backwards and set up for 8" rear wheels. I'd want to cut and raise fenders though or this machine is just going to be too high off the ground.
The way this pressed frame is laid out, the back half steps DOWN 1.5" lower than front half (you can kind of see this in 6th image down). Right now, the bottom of that step-down is 4.5" off the ground, w/ the 15" dia tires currently on it. If I change to 8" rims and 16" tires, that would put the lower frame portion 5" off the ground and the top of tires into the fenders. I can probably tweak fenders for 1/2" clearance w/ out much trouble.
My question to you is, Is the 5" rear frame clearance too much? Just forward of the lower rear frame, the "main frame" would now be 6.5" off the ground. It'd be nice if I could cut that lower part of rear frame off and raise the rear axle and fenders so I could have 4" - 4.5" rear ground clearance. Not allowable? What do you think? Any alternate suggestions? I really appreciate your input as I've never done this before.
So, I can either move these rear rims and tires (15x6-6) to the front or use what I now have for front 13x6.5-6. What do you think?
