1. You can buy a plastic piece from JC Whitney for $6-7, that's where I
got mine. I gave it away yo my father-in-law and he's never returned it so
I did a variation on the 2x4 (which always splits) and used a hockey
puck. Cut a slit down the middle and it works great. If your cup has
taller rims, stack 2 and contact adhesive them together. Hockey pucks make
great bench blocks too....
2. Common in the telco field. $40 for a set, can do coax. Sensing
through drywall will be tricky as the signal attenuates rather quickly and
the pickup neds to be close to the wire. But.. I'm sure there's a high
power model and the variable volume pickup does help a bit as well...
3. Sorry, don't weld nuts... :-O
