Have not had the opportunity to work in the shop for months. 3 trips, started a new job, and had some slab work done on my outside entry shop.
I’m in Mexico on that third trip now, and the new job has been kicking my butt.

Been a while. Got some shop time today, and engraved the 50 indices on the micrometer adjustment knob.

Finished up a few operations I need to take pictures of and upload. Yesterday I finished out the motor pully lathe operations, and now I need to cut the keyway. Ill post pictures of that as well. Thinking about taking a cut off wheel (dremel) to a HSS parting blade to cut clearance into the blade, and then using that in the lathe to cut the keyway. I don't have a spindle lock, but I guess low gear should hold it stationary enough for the process.
The cutting edge of the parting blade is narrower than the keyway I need to cut, so my plan was to hold the parting blade horizontal in a QCTP holder, and plunge cut the keyway with Z, adjusting depth with X. Then without moving the headstock, Move the QCTP holder up/down to plunge to the keyway width.
Just typing this has made me second guess on weather or not I cut the pully to the correct internal angle. will need to look into that later, but will include pics.

Looks great! What did you cut the graduations with? I have a part I want lines like that on. I've done it on other things with an engraving type bit, 90 degree point v-shaped, but I think that yours looks better. I have an indexer, so that part is set.
