I made some scratch built motor mounts today.I started with a piece of 1/4” x 3” flat bar for the motor plates and some 1-3/8” x .120 wall tubing with a couple rubber bushings.
Using a piece of cardboard to design the legs.
For the leg piece I started with some 2” x 2” 3/16” wall square tubing and cut it on the band saw. I also made a hole for access to the lower bolt on the motor plate.
All tig welded up and the mounting tabs being mocked up.
Passenger side motor mount.
