Mini Mill Drawbar Problems.
Stilldrillin:
I`m now beginning to get the hang of this mini (tiny) milling lark..... :thumbup:
It really doesn`t like small cutters, like this tipped 1 3/4" three leg.
It really sings with this 10mm carbide three leg.
But my main problem at the moment is removing the tool from the morse taper spindle!
However gently I nip up the drawbar, I have to beat the tool from the taper socket..... :bang:
I started with my 3" dia x 1/2" lead tup.
Thinking it needed more of a rap I tried this piece of bronze......
Hurts me hand...... ::)
Any ideas / opinions anyone? :thumbup:

Try clamping the spindle before you give it a tap. Normally you shouldn't have to wack it too hard.
Cheers

Easy, don't take it out.
I put everything in my ER holder, drills, flycutter, heck even a milling bit sometimes as well.... :lol:
Since the holder has been in I've only taken it out once. That was after beating seven bells out of it mind. Now I just leave it there.
Why do you need to take it out?

Hmmmm.....
Yes, you`re right Darren! :clap:
Putting everything possible in the ER holder does make sense! ::)
BUT, I`ve got 3 tools, so far!
AND I come from a toolchanging background. Look at the 20 tool carousell I used to "own"......
My thoughts were.
Milling m/c`s were designed to hold many different tools.
Morse tapers were designed to drive only by the taper`s friction, and to be drifted apart.
This mini milling`s causing me many re thinks....... :scratch: ::)

David,
You're problem is an age old one, and the MT system is one of the worst. That is why even some of the medium sized benchtop mills now are going for the easier to release systems ie R8.
Maybe a reaction weight would solve your problem. Get a lump of soft metal (or cast in lead), shaped like a deep ring, say 3" long. The thru hole should just be able to get the chuck thru it. Push this against the bottom of the quill, while you tap on the drawbar. If you don't do this, you will be knocking crap out of the quill operating system, and you will eventually damage something.
Or for things like your face tool, make up a pair of fine wedges to go between the tool and quill bottom. Similar to these.
