I recently found that Victron makes DC bus bars for battery work with studs
already on them. Up to 600A models are available.-GlennSent from my

PMTo: RE-wrenches;Cc: William Miller;Subject:Re: [RE-wrenches] Large current
battery combiners, UL ListingColleagues: I am gearing up to tap some more
copper. I assume this is a pertinent subject since bus bars are going to be
needed frequently for any storage work. I bought the fancy drill press with the
tapping function and I am setting it up. I ran a few tests and the
functionality of the tool is pretty amazing. I still need to work on
programming it to reverse when needed. I am close. I also ordered a cross
vise for part holding. I found this tutorial on line that has provided me with
some valuable insight on different styles of taps. William Miller Solar17395
