How about I just send you this chisel for a good once over on the belt sander.
I bet a decent Router VFD would actually work pretty well on most 110v home belt sanders... The issue is typically that the motor doesn't cool right at low speeds... Not that the motor wouldn't work right.. Alas - I don't have a normal belt sander either.
Tis the life of a Semi-Neander I suppose...
For the cooling problem when you run a 3 phase motor at low speed with a VFD, just get a fan and aim it at the motor. The air blowing over it is usually plenty enough to keep the motor cool.

[Also, those router speed control units will only work with a universal motor - they will not work with an induction motor. You need a VFD and a 3 phase induction motor if your unit is not a universal motor.]

Go into the world and do well. But more importantly, go into the world and do good.
