This is a design I made from scratch a few years ago. I’m just sharing the idea here, the files are on one of several old SSDs in a container I don’t care to find. (more pics below) This works backwards to how you may first expect, lefty tighty || righty lucy.

The locknuts in the knob get jammed together and held in hex recesses. These nuts are only used to hold the screw securely by the threaded end. There is a nut embedded into the cylindrical spacer that is tightened against the tapered head of the flathead screw to expand the wedge in the miter slot. The cylindrical spacer looking part is locked into position by two slot protrusions that are part of the print, and fit into the channel of the feather board tool. When the knob is turned left, the screw and the cylindrical spacer’s internal nut are tightening together, and expand the slot wedge.

I tried many nut-type combinations, but double locknuts jammed together along with a spline indexed top cap with hex locking recess is the only combination I feel truly confident to use around a tablesaw where my digits are at risk. In the pic with my hand I’m pulling up white knuckle hard and it is nowhere near budging. Up would be its weakest orientation too, it is even stronger in line with the slot channel. This is not a Tee slot either, just a 3 sided simple 3/4in slot. image

    Left-hand threaded screws and nuts are reasonably common, albeit, more expensive. Those would make it righty-tighty.

    In the pic with my hand

    I’m not seeing a picture with a hand. Only 1 picture showing to me: the disassembled stuff.

      Maybe catbox.moe was down. They show up for me still. I think the main image is cached on Lemmy and transfered via the messengers configured by admin between servers. If you still don’t see them I can try to modified the embedding tags. They used to require ![image](URL) but I used the currently supported ![](URL) version that has worked for months now as far as I know. Perhaps other instances only support the old version with images. I’m going to edit just the hand image out of all ~4 extra images. I don’t know how long that will take to propagate between the servers though. It depends on how EE and World are configured at the admin panel.
