The HF drill press has been performing yeoman service in the shop for a few years now, but one thing that really bugged me about this tool was the quill stop. Instead of the typical nut-on-a-threaded-rod setup, it uses a pinch bolt and sleeve on the collar of the handle. It's not that intuitive to use and if you don't have the bolt really tight it slips.
Grizzly has the same style of drill press with the quill stop I wanted, so I d/l'ed the manual for the parts numbers and ordered a quill clamp, bracket and spring-loaded split-nut. The threaded-rod on the Grizzly is metric and split nuts are very hard to find for this size, so this was a good excuse to try my hand at singe-point threading. It went reasonably well for my first attempt and I got a usable rod.
That's all the parts and the rod I threaded is at the bottom.
Tapping the holes for the bracket in the casting of the drill press. I didn't poke through the side into the internal cavity as it looked like I stayed inside the support webbing. Sometimes an educated guess is good enough.
Here it is all assembled and it seems to be working out well. I'm not using this setup for precision drilling, so you just move the quill down to where you want it and clip the clamp right above the bracket. It was a fun afternoon project.
