The mechanics would be a nightmare to me, also. To others the
electronics would be a nightmare.

Contactor and resistor?...way too complicated.

You want to put that monstrosity on a tilting arbour saw, mounted
under the saw table and in the path of the saw-dust and have it work
reliably???
Not going to happen - guaranteed.

It's BECAUSE I was a mechanic for several decades that I would NOT use
a brake caliper for the application.

As a guy who has done all of his own vehicle maintenance for 40 years now, I
have to ask what you observed in your experiences, that causes you to make
this statement? I don't know if the brake caliper idea is the most elegant
solution, but I sure can't see anything in what you are saying that would
suggest it is not a workable solution.

Suitable placement of an air nozzle tube to clear the caliper frame
every hour or so would go far into making this device work for more
than an hour. You'd have to keep the sawdust from piercing the seals
and/or building up on the frame
Which just adds more complexity, reducing the reliability beyond the
acceptable (at least for mr) level.
