Hey dude. Nice work with your writeup and pics
I just wanted to let everyone know that I tried the
'Optional: 4 bronze flanged bearings can be substituted for the nylon bearings. McMaster Carr part # 7815K19'
and it was EXTREMELY noisy! I just got my urethane ones in today so I'll be throwing them in tomorrow.
Nice work with the pivot bushings. If I didn't already have Tom's I would be placing a third order at McMaster
