Just catching up on this thread so probably missed a lot but....
What's the diameter and thread on the black knob you need to replace? I have a couple sizes left over from re-building my machines.
Is that dark wood rosewood or cocobolo?
Lastly for now.... why are you spending on upgrading your service if your planning on moving soon? Seems better to put that money aside for wherever you move to, which will likely need that same work done? I know you want to run the saw once you get it together.... but I wouldn't want to invest that unless I was happy staying awhile. Believe me I know what it's like to dump thousands into electrical work.... and I don't even own the building
I think my last shop move put me out about $15k.... not all on electrical, but more than half.
good luck,
