2 x 72 Belt Grinder
Not My complete build but enough to get you started design is for 1/2 plate 1/4-20 cap screws for the main frame. you can either bolt or weld the base. the gas strut is an 80lbs 7.4in (extended) part with 1/4 20 ball head studs. the cam over design on the tension arm makes belt changes really easy.
