That is fairly similar to whats already in the BS-1, except the BS-1 has only one locking screw. So thats pretty close to what I am looking at, except the motor, unless it has a builtin gearbox, is obviously too puny to turn it under a good cutting load. I intend to have the torque to move it while cutting. I've two tables already, but neither can be moved when a cutting load is applied. It took me half a day to make a big drill bit 2 years ago when I was building in a wheelchair ramp, a job I should have completed in 30 minutes or less because a 270oz/in motor directly on the worm couldn't do the twist while cutting more than 2 thou deep per cnc loop. Very slow going on a 3 flute bit. Life's too short to put up with that BS. Another possibility is a right angle worm drive gearbox on a circular mount, so the motor could be loosened and rotated to clear stuff regardless of the tilt. Something like: <https://www.ebay.com/itm/Worm-Reducer-NMRV050-19mm-Input-Shaft-Gear-Ratio-Speed-Reducer-60-1-100-1-Ratio/193329956155?_trkparms=aid%3D555021%26algo%3DPL.SIMRVI%26ao%3D1%26asc%3D225074%26meid%3D4f3a76f9cf8142fcb1041038832557eb%26pid%3D100752%26rk%3D5%26rkt%3D20%26mehot%3Dco%26sd%3D174176794081%26itm%3D193329956155%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplRVIAMLv5WebWithPLRVIOnTopCombiner&_trksid=p2047675.c100752.m1982> Shaft adapters would need to be made, and a rotate able mounting centered on the worm shaft would have to be made but thats a heck of a lot simpler than my original idea. Make the whole thing quickly unpluggable from the side to protect it from missfires of the hoist. What do you all think, do you see any problems I don't in my enthusiasm? Thanks all.
