My vise needs some new jaws so I thought I would make them from copper. I've never machined copper so any suggestions would be appreciated. Will need to square up the stock, size, drill and countersink the mounting holes.
This forum's search function returns 12 threads (including this one) about machining copper when using "machining copper" as the search criteria.
Btw, not trying to be a smart ass or anything but just wanted to point out the search function does work well if you use the correct criteria. Google too.
Just yesterday I machined a couple of copper details for a resistance welding fixture. Took no special precautions, milling, drilling or tapping. Used ordinary cutting oil for tapping 1/4-20 threads. The metal is indeed gummy, but I had no problems.

I asked that question a while back and the guys told me to use Milk as a cutting lubricant! I was having trouble drilling holes in 1/4" copper plate and the milk helped quite a bit.
I'd choose a different material for the jaws personally.

Is that regular, 2% low fat, 1% low fat or skim?

I assume (but don't know) that you would want to use whole milk with the butterfat in it.

Maybe you ought to consider sheet Lead. That is what I use in my Bench Vise when I'm holding something I don't want scrastched or marred. Works very well and is easily moulded to fit the jaws by hand pressure or a small hammer.
Using Milk as a lubricant for Copper: this was discovered when the only types of Milk available were Sweet, Skimmed, or Buttermilk.
