Hi Phil

All thats left now is the outer part of the quill; and the feed handle with return spring and the small casting with the stub shaft that the new pulley is on

I just found the box; it slipped down behind my set-up
I'm re-org/zing the shop and it came to light

The bearing is a Timken NKJ20/16A

What a fantastic thread. Read's like a well written book. Great picture quality too.

I want one !

Heres a stop action photo of the new mill in the process of making an Imperial Japanese Navy Heavy Cruiser Propeller (Takao class) in 1/200th scale

And heres how big that actually is; yes it's in Bronze

That looks awesome, although it looks like you need to do that one with the 4th axis

Do you have a cam package that can do simultaneous 4 axis movement to do something like that?

I have some stuff I want to program/get programmed that needs simultaneous 4 axis motion but I dont know how(turbo impeller and compressor)

I made a simple jig and cut the other side
Looks cool
Catch22 stopped by and watched it cut; we both watched as i took a cutter out; Duh; hit the holder screw; well no one's perfect

Excellent work!

Answer; my 4th uses ER25 Coolets; max size is 16mm; this is 19mm stock

[JFettig]

turn down the end and pop it in

[Stevie]

why?
It worked as is; that would waste material and bronze is not cheap

How did you hold it down when you flipped it? pics would help.
