Well at least this project only took 2 weekends instead of way too long like the last one.

It’s a simple pair of table stops for my X-3 mill. The last project needed a couple slots milled and I found that I had trouble stopping at the same spot at the ends of the slots. A couple months ago I had asked you fellows what the slot on the front edge of the mill table was there for….I didn’t have a clue. You fellers enlightened me so I decided to make some adjustable locking gadgets.

I sketched out a plan and scrounged up some 1” x 2” mild steel and whittled out what you see here. They’re probably bigger than they need to be but man, I got tired of cranking the handles! Who knows, I may find a need to attach an indicator rod or something later. If so, there’s plenty of meat there for tapped holes.

I made the slot nuts from some round stock with 2 flats milled using a spindexer. I even remembered to partially part them off before milling the flats so the parting blade wouldn’t see an interrupted cut later.

I’d planned to make a couple of snazzy knurled knobs but found that hand tight wasn't tight enough, hence the ugly hex nuts. Form follows function, eh?

Looks good!

I notice you have a measuring scale along the front of the table. IMO, one of the best things you can do, short of a DRO, and a heck of a lot cheaper. A couple of suggestions to make it even better:
Reid Tool www.reidtool.com sells adhesive-backed Mylar tapes graduated in tenths of inches, which I found to be convenient when I had a similar setup.
Make the pointer adjustable left/right over a distance of a bit more than an inch, so you can "zero" the pointer on an even inch graduation.
