Now we're trying to build a battleship with a Cuisinart and some oily stuff.
The quys successfully machining copper blocks are using tiny carbide mills spinning at 8-12k RPM with specialty oils.
While I am no metalworking expert (though I did stay at a Holliday Inn last night!). I do have a lathe and mill that I play around with. All I know is self taught from what I could find to read up on. I have been ammazed by what I have been able to do. And I have the scarrs to show for what didn't work.
Not to discourage you though. What you want to try is where many start. The truly persistant prevail. The best way to learn is a little reading and a little trial and error. Just make sure everything is clamped down
really good.
