I've got some aluminum pool copeing that I need to bond, does it sound reasonable to try to drill and tap 10/32 machine srews for this . I would have used a screw and nut but the concrete contractor already laid the wire and theres no way to get underneath to put the nut on. The only problem I see is the material thickness is only .062, will only get 2 threads in it. Anybody here no if there's a minimum number of threads that need to be cut. Thanks much.

The screw would have to be rated for concrete. I would have the pool guy remove the wire. I am not sure what coping is so I can't advise-- isn't there rebar or steel you can bond to?
Dennis, copeing is the aluminum top rail (almost like a bull nose tile shape) that goes around the pool top and the cement is poured up to it. It is not mechanically connected together around the perimiter(22 individual pcs) and it is required to be bonded. I am quickly finding out why electrical work is so expensive when it comes to pools. Maybe once you've done enough you get it down to a science.

I agree it needs bonding but what a bummer.
Lugs and screws but I would want a bolt. Here is what the NEC says about threads
