I have seen a radial arm saw that can take a router for overhead work but wondered if there is a stand available to hold a router above the work.
I have found a table which can be wound forwards and backwards and side to side which is really intended for a small milling machine.
As I am a skilled toolroom miller I can see many advantages of mounting a router overhead.
When I was at work I often took wooden workpieces into work to cut on my machine during lunch breaks.
It would be nice to do the same in the workshop.
When cutting housings (dados) a few turns of the handle and it would be done.
A known distance for each turn (1/10") would enable very accurate cuts to be made.
