That’s looking really good. Appears like it will give you plenty of adjustment range with that style of post. Dave
For a 1/2” to stall that motor indicates gearing may be too high or something. I’ve drilled 1” holes with same motor on my mill and drill press without stalling but I may be lower geared. Dave
Got some more work done on the first toolholder; actually took a few light facing cuts with it as-is; will work just fine...However-I managed to snap my only 8-32 tap while threading the height-adjuster screw hole, oh how I hate carbon steel plug taps Will be ordering a couple spiral-point HSS replacements, and also a bit of a looser tap drill; as with 1/2" of engagement I don't need 75% or better thread, that's for sure...While I might have to wait until I can get new taps, I can still do all the other ops on the remaining four blanks; now that I know it will work every bit as well as I hoped...Jesse
Hold off on the larger hole. Those gun taps cut much easier.
Impressive project, and tenacity, Jesse.
Keep chugging along, your making progress and that’s what matters!Dave
