Yes, I’ve done this a number of times, before I started really looking more carefully at the Tayda pictures…
You'll want some sharp flush cut nippers, and possibly (if you have a dremel) some cut off wheels.
1. place a correct pot and our test subject so the 90 bend is at the same height, and mark off where the end of the correct legs are, and also right where they get thin.
2. cut the legs off at the new full length mark.
3. mark across all three (now shorter) legs to show where the thinning happens.
4. this is the only tricky part. You need to thin the legs to that mark you just made. If your nippers are sharp enough, you may be able to just make two very shallow cuts, and two long cuts, and be done. The legs are thin, bend easily, and are fairly soft metal… I’ve been able to thin them off easiest, using a cut off disc (but more like a miniature sanding disc, pressing the leg into the flat surface of the spinning disc).
As an alternative, you could just cut them off square where they get narrow, and solder some short bare wires on. (This of course didn’t occur to me until just now…) but it wasn’t bad, just added a bit of time to the build. I’ve even bought the longer ones on purpose, when I’ve wanted to locate the knobs a bit higher or lower on the top, and keep the board in the same place.
