Yep, you're right on what I did there. Unfortunately this requires opening
up the side panels and clunking the pulleys round that are hidden inside.
Since I'd dumbly forgotten to turn off the controller before I did this, as
it went off the limit the machine's brakers gave a clunk as they turned the
power back on. A reminder to check it's off first as I've already mangled
one finger under a paving slab and slash the tip off the other in a gate!
Maybe I could remove a whole hand or something in the pulleys.

I was thinking of taking apart one of the 'Bug' joysticks we had for our
A1200 Comadore and wiring it in to use as a jog control. I may put it in a
box and add some momentary switches like you suggest to kill the limits.
Holding down jog with my finger for more than thirty seconds sets it off
wobbling for some unexplainable reason. It'd be nice to be able to select my
feedrates variably. The control has an infite feedrate control from 1 -
1250mm per minute but when it's in manual mode you can only select step,
slow & fast. Also, the variable speed spindle doesn't have a tach display on
it, the tach must just to be to verify the speed to the VFD.

Indeed! I have one other friend who's into this sort of thing but no where
near the standard obsessed level I and 99% of this board are at. The other
person I know is a older and has a bad back.

I've just this minute misplaced £156 of my hard saved cash for a goodie bag
full of car-bidies and other bits of, ahem, essential, tooling! `.^) If
only my wallet was big a thick instead of puney and wimpy. I've heard from
this list and friends though that carbides do last a huge amount of time
compared to HSS.
