Making my own mod vise, not perfect but it’s getting there!
Showing a little of what time and trial and error can get me. the sweet saunders mod vice have been on my want list for a long time but I choke when I realize it‘ll be $500 to my door. I’m working my way from this cnc to the next one (for a fourth time now!), and am heading towards printnc metal cutter land.
I knew I could get a functional one going on my own, but that means a lot of aluminum cutting, and doing some stuff I’ve never done before.
I reused some leftovers from a failed printnc z plate, and had some whoopsies on the countersink bolt holes. it’s not done yet as I have to redo the main clamping bolts but I’m happy that I got to this part.
I cut all of this on a pretty regular openbuilds lead machine, with a wimpy dewalt router, nema 23s, linear rails on the gantry and z, and a super o-flute 1/4” bit generally. All workholding was tape and glue. Cutting formula was a combo of deep and thin, 6mm doc with 5% stepover, 0.05mm/tooth. Or 1.5mm doc same chip load, and closer to 30% stepover. Repeated finish cuts really helped and took no time to whip around at full cut depth 8-12mm at once.
I was very happy with the cutting after figuring out a great cut formula (for all but the tapered hole).
I know it’s not perfect but it’ll do what I need it to do. Not bad for a trim router.
