new SuperMax 30taper --Needs a drawbar or power drawbar

[countryguy]

Hi everyone, Been burning up the forum on the new Mill. It's in the Garage now and I've started to dig in on her. I see that it has no drawbar or power drawbar. The manual notes it's a NST 30 7/24 (or NMTB right?).

So here is the question. Power drawbars seem pretty cheap. But what kind/type? Will a BPclone type work? there is a mounting top (pic below).

There is also this Pnumatic actuator or some kind on the side (see pics).... And I'm unclear what that is really for?

so- Can ya'll help me find a powerdraw bar setup? Maybe even a tool changer for a Supermax (would be sweet!) really... Do they exist
Short-term - What do I get just to have a manual drawbar. Is this just a threaded rod with a bolt top like my manual R8 Dbar?

thanks everyone!

You can build a drawbar just like a BP type. I'm pretty sure the NMBT 30 tooling is a 1/2-13 thread. I would get a length of Grade 8 allthread and make it out of that.

As far as the pneumatic cyl, back gear shift maybe?

OK.. 1/2 13 is correct Jim. Thanks as Always!! Grade 8 allthread, McMasterCarr or my local Production Tool Supply place. Not an Enco, but very close and always a great Clearance table!

OK, So I see these are really fun projects! power drawbar...Yeah, I can do that. Fun Fun Fun.

I built my own power drawbar many moons ago...

Looks similar to the one you found except I used an electric impact wrench.

Thus ends the saga of no tool holder mounting. No to dig up the tool holders themselves.
Have a wonderful 2015 all!

It appears that the spindle nose keys are missing, and the screws that held them on have been broken off; you will need to replace them to drive the adaptors that you buy. As far as a drawbar is concerned, I would machine one from scratch with a larger diameter upper end to engage the hole at the top, and extend it about 3 or 4 inches above the top of the head, and mill flats at the top about 3/4 or 1"long and 7/8 across the flats (standard size for a 1/2" extra heavy nut) Unless you plan to do a crazy amount of tool changing, a power drawbar is unnecessary.

My super max has this cylinder it is a spindle brake it engages just for a moment when stop is depressed. But this is an older thread and I bet you know this now.
