Rubes, also a good one there drilling sheet metal with cloth, which I'll use.

That video sent me down a (good) rabbit hole, because I noticed that he (Marc Presling) also had installed the same bluetooth DRO on his mill as I did, using TouchDRO software -- then I found more videos about TouchDRO, including those by Yuriy -- who originated the hardware/software.
Of course I didn't get much work done in the shop today....
