I recently spent roughly an hour drilling through copper bus bars, surely there's an easier way to do it? :ack2:

Unless he was drilling them ''Live''!! The naughty boy!! lol!!
cutting fluid - corded high speed drill and cobalt drill bits, I n drill through RSJ's with that lot so copper should be no prob. bob.
I know it’s not practical for site work. Punched holes are far better than drilled.
Now who would do such a thing lol
Then after live drilling,the mate happens by and he gets the mate to put in the final bus bar cover bolt Thats when the H+S get involved with one of their Spanish inquisitions and he gets sacked for putting the poor lads life in danger
Water laser makes a pretty enough job,but maybe the odd issue in a live bus-bar chamber...:icon12:
Hydraulic punching rigs were once on my repair list,10,000 psi power-packs...inch and a quarter of road plate - no problem...but do not be tempted to try doing the same on a piece of Kevlar matrix...stuck like King Arthurs' sword...not my best bit of R&D :conehead:
What is a 'water laser'? I have only come across water jet OR laser cutting ... though often companies who do one also do the other! I really don't want to be too pedantic ... I just can't help it ... 'Kevlar matrix' is an interesting term. The Kevlar in a product made from Kevlar is the fibre reinforcement which is surrounded by a 'matrix' that is generally some form of thermoset plastic or thermoplastic material.
If a hole is drilled and tapped, then studded, does this affect the CCC? I'd have thought the bolt/ stud would in effect become part of the bar, but I'm ready to be educated!
