I'm still working on my solid Cu host. But I keep running into a problem machining the copper.
I started out with a 6" X 1 1/2" bar stock.(not sure if it pure Cu or not, bought it off my scrap pick-up guy)
Every time I get deeper then 1" with the 3/8 boring bar, I start getting terrible chatter.
I have tried Protap Gold, Tap-matic GP and Tap-matic Al ,cutting fluid with the same results.
Anything that stops the chatter, just gums up the carbide blade on the BB.
Anybody know of something that works good on Cu?
The Protap Gold worked great until I started with the boring bars.(made a hell of a mess although) I have never made anything close to this large with Cu. It sucks!
