Gorton Mastermil model 1-22

cutouts, 1/4" deep, both sides

Easy:

the manuals are here. Manual shows possible tapers as B&S 9 or 10, (DIN2080) ISO30 or 40; your drawing looks line an ISO 30 adapter (if the 2

1/2" OD part is solid and not split around the circumference then it's almost certainly ISO30). Martin

That's correct, there is no groove routing around the circumference of the outer rim, thanks!

Alex

To further emphasize, does anyone know how Ed would replace the current collet system (ISO 30-40 thanks to Martin) with an R8 system?

Alex

Congratulations on your friend buying one of the finest mills ever made. The 1-22 makes a Bridgeport look like it was made of silly putty.

Did I mention that I have one? I do not however have a power feed unit :( When I can scrounge up one for a Bridgeport/clone, Ill adapt mine and install it. I cant help you with the power feed.

I do however have a couple copies of the manual. Parts list, electrical etc etc.

I put a VFD on mine as mine is the step pulley version and its Da Bomb for all work. Taps great too

If its like Most of them..its standard 30 Taper.

30 taper is head and hands better than R8, and is commonly available. You may use virtually all 30 taper tool holders, NMTB, Cat 30, etc etc by simply making a new draw bar. One uses 3/8-16 thread and the other is 1/2-13. Lots of it on Ebay

cutouts, 1/4" deep, both sides

I do have some surplus 30 taper tooling Im taking to the Visalia show, including some collet holders, an Original Gorton 30 taper Quick Change setup with tool holders etc.

Its one hell of a mill. The only down side is the quill has a fairly short travel and this means if you are doing tall work, even with the table all the way down..its hard to get a drill chuck and a long drill bit in there.

So I got a set of collet drill holders

Any questions, feel free to email, call, send a homing pigeon, etc

You dont. And shouldnt.

The difference is that of a volkswagon (R8) and a Dodge Ram (30 taper)

Well ... if it is an ISO 30 (also NMTB 30 and a few other designations), then the actual tapered part is the same as the taper on an R8 collet -- and the size is right -- except for the bore to clear the larger shank of the R8 collet.

I, personally, would keep it as a 30-taper, as I feel those to be more rigid than R8 collets -- and certainly a better grip on an endmill. (I have a Bridgeport Series-I CNC machine which uses the

30-taper, and a Nichols horizontal mill which uses the 40-taper, and which can (and does at need) accept 30-taper tooling with an adaptor sleeve.

If it is a 40-taper instead, there might be enough room to accept the shank of an R8 in an adaptor.

One thing which I would *not* do is just start boring the spindle out to clear an R8 shank, as you *might* wind up cutting into the mounting surface for the spindle bearings.

Good Luck, DoN.

Thank you thank you thank you!!!!!!!!!! Ive been looking for a manual for my 0-16A

Bravo!

Well, you are in 1000 oaks, he is in Carpinteria as am I, so I'll print your reply and give it to him today. You two can collaborate. He does a lot of work for racing cars and motorcycles, no cnc stuff.

Really great reply,

Alex

Excellent, thanks and your reply will be printed for him to read, he might call you, I don't know.

Alex

...and, Ed only paid $500 for it...what a deal. saw one online for $4,000. Alex
