| Cutting copper with milk
Hi
just thought id pass this on.
had a bugger of a job today machining a lump of annealed copper bar. Bit like trying to machine toffee every cut the copper grabbed or plasticised on the tool.
After a lot of swearing i remembered a tip I picked up from my father. milk yup house hold tea addative type milk. filled a jam jar with moo juice and applied using a paint brush worked a treat. no more grabbing and a half way decent cut.
cheers kevin
P/s tallow works reasonably well but is getting harder to find. |
