It's about time to shape and slot a new nut for the extremely slow build. Clamping the thing when shaping, marking and so on has been frustrating. So, I finally made a little holder to make that fiddly work easier. Not unique in any way but relatively easy to make and it works great. It is made to fit in a larger vise or to use freehand, if using some kind of sanding machine to shape the nut. Oak, some aluminium, a M6 screw with a knob, and a threaded insert. And a bit of brass rod in the pivot point.
I remember the FastCap motto: "Fix what bugs you". 🙂
What's the advantage of your jig over an ordinary small (hobby makers) vice?
I don't know, because I don't have a small vise narrow enough for shaping nuts. 😉 But it is excellent to use handheld instead of pliers when using the oscillating bandsander and trying to save the fingertips.
