Jazz,
Just out of curiosity have you machined bakelite before?

No sorry it's something I've never worked with.!

If you have any probs with the Aztec just let me know and I'll Email you what I have.

An excercise in trying to mount concentric and mill. Thin one: the edge varies from 0.34 to 0.4 mm so not bad. But the mount was in wood (just a 26mm hole bored) so had some give. The top part was in ali to form a clamp to hold the 2p down, 25.6 hole with a small 26 dia 0.5 deep lip. Was trying to get the edges as thin as I could, must have over cooked it as on attempt the 1/16 end mill bit snapped. It only has 3mm flute length so I think it touched the clamp edge which was enough to stress it. T/C ouch! Took some vid of the v carving, mute your sound, it's terribly noisy!

Did this about 15 years ago, never used them, intended for an O guage model of George Stephenson, thats a Black5 BTW with unique valve gear. They were never used (yet) and they are taper fluted with 1/32 bit. They are out of 1/16 N/S. Never been cleaned up and still have the support tabs and smells of treflex, so nothing changes!

Were done on this same machine as well, mild steel. Something else I have to finish!

But back in BC (Before Cnc), we had a device called a file :-)
