If you got stuff worked on by Keith, you got good machines...

We have a Cincinnati Bickford drill at work. I cringe every time the shop guys use it. Could be a very nice drill if cleaned up. Works awesome. Except when they think it is drilling too slow, and "speed it up" and literally melt a 2" drill.

Very nice drill press. I always wanted a radial arm, but could not part with the floor space, and up to a few years ago that was a premium with a 23 x 20 shop.
And wanting and needing were two different things. You got a big shop coming and real estate is no problem.
It'll be a great tool once you can get it to drill vertically

I completely agree with you. Pretty cool guy in person. He puts a lot of time into his machinery for sure.

On the Gorton Mill the spindle has what appears to be a Universal Engineering Kwick Change holder size 200.

If the spindle in the mill is nmtb 40 shouldn't there be a draw bar holding the tool holder in? There isn't.

I have a few collet holders that fit the Kwik Change and a full set if ZZ type collets.

Did you check to see if the draw bar is broken or even missing all together

That particular Gorton mill will not have a draw bar. That nut on the bottom of the spindle is what holds the adapters in the spindle. You're pretty much stuck on what tooling you can use. If it is really a true No. 40 taper in the spindle, you can use standard NMTB 40 holders, But, you will have to modify the flange to fit into the spindle. Now, if it is a true Erickson (Universal Engineering) spindle, and Gorton supplied them in their mills back then, then you can only use the adapters with the big ears on them, the Quick switch ones.

Oops, I may have that twisted up. Erickson spindle would accept modified No. 40 adapters. The Universal Engineering spindle accepts the Quick Switch adapters.

Sorry, Ken

Hard to say.

I'm not familiar with the Gorton mills.
It does look like you have some type of NMTB to Kwik Change master in the spindle.
Being you can see a drive-key-slot for the NMTB, I assume the master comes out, they would not have cut a drive-key-slot if the spindle was a Kwik-Change "spindle".

Just maybe you have some type of power draw-bar system.
look on the other side of the spindle and see if there is a drive-key in the NMTB slot.
you don't want the master spinning in your hand if you activate a power draw-bar.

An exception maybe a pull-stud system and a lever releases the holders

Until you figure it out.
A word of caution place something soft on the mill table. so if the master drops out it will not damage the table or master.

I'm very familiar with Gorton Mills...
According to the parts book there was six different spindle configurations offered by Gorton. None of them are Erickson or Quick Switch ones.
All you have to do is reach over the top of head and the spindle and feel for a hole thru the spindle or a square drive on the end of the draw bar. It'll either have or it will not. If it doesn't have a draw bar, it is a true Erickson spindle replacement for No. 40, or if it takes UE Quick Switch adapters, again it could be an integral spindle.
And it's possible it is a NMTB No. 40 by Quick Switch spindle adapter. I doubt this is the case, it would stick down about 3" below the mill spindle if it was. The pictures don't say that IMO. Ken

I couldn't get up high enough to see if there should be a draw bar but I don't feel one sticking up.

Looks like either way the Quick Switch tool holders aren't
too expensive. I just need a assortment of endmil holders and a Jacobs chuck that will fit.

Bonus is all the nmtb 40 holders and boring head I have. Save it for a machine that will fit it.

Great timing on this thread! I just scored a Gorton 1-22 with a 40 taper Spindle nose. I haven't been able to find anybody else with the 40 taper.
I have a question about your drawbar.
Mine came with a homemade drawbar.
When I started looking in to it, to make a new nicer drawbar, I realized the cutting spindle bore wasn't wide enough to pass 5/8" through.
Is your 40 taper spindle the same? Can you remove your drawbar from the top?
I guess this is specifically directed at IronMan and OldRedFord (and anyone else who has a 40 taper spindle).
Mine's set up for NMTB 40, and I was hoping to just be able to swap drawbars to swap between CAT40 and BT40, but being as the drawbar doesn't pull out the top, I either have to swap from the bottom, OR make an extension / adapter to take up the space of the NMTB 40 shoulder (and make one for each toolholder probably, because it will not be easy to change out from the spindle nose).
I'll most likely settle on just using CAT40 (because they're so abundant), but I want my cake and to eat it too
Thanks!
