Putting the tool length switch atop the tooling plate has the advantage that it’s higher than most of the workpieces, but it also soaks up a bit of precious real estate. Moving it off the plate to the table puts it nearly level with the top of the plate, but at least now I have room for clamp blocks and suchlike:
It turns out that Sherline T-nuts protrude just an itsy above the top of the table (which lets them locate the tooling plate to the slot, for example), so I shortened one by filing it down to size:
Now, I’d like to front as if all that happened in a rational and well-thought-out manner, but the fact of the matter is that I completely used up one 10-32 stainless socket-head cap screw while thinking it was somehow still bottoming out in the slot, before realizing that the T-nut was sticking up. Drat!
