Default Gorton Mill

Have the opportunity to check out a Gorton Mill.

12x48 table. 40 taper tooling, power down feed on the spindle, power table feed, power knee. Bunch of tooling and collets included.

Anyone on here ever had a Gorton Mill?

It's a model 1-22

Haven’t ran one of them. Lots of hits on google, so it seems they are out there. Looks like a scaled up, slightly beefier version from a standard Bridgeport.

40 taper tooling can be an interesting animal. It’s a common taper, used on a lot of conventional and CNC mills. The flanges and the threaded end for the pull stud/draw bar is where things can vary. For the most part with this size, most people buy a 40 taper collet holder and use that a lot of the time. A drill chuck with a straight shank saves changing that holder out.

Here’s a pic I scooped off the net.

I have a smaller Gorton and it has done what I needed so far. It has a home-made adapter to r8 from the "gorton taper" and has the smallest bit of play. Not enough for me to worry about though.

Bought it for $1500. Digging through the tooling for it there's a nice set of collets and a cat 40 holder.

Sorry no pictures yet. Can't take any pictures of it where it is but when I pick it up in September I'll get some pictures when I get it in the shop.


Additionally I bout a legitimate Cincinnati Bickford super service 21" drill. I'll post more details about it also when I bring it home to the shop. It's been completely gone through and cleaned up and painted.

CAT 40 and BT-40 the metric side are very similar. I have the BT spindle on my mill. CAT and BT have the same taper and taper length.
BT tool holders have the ears directly 180 degrees opposite each other. CAT do not. One ear is about 190 degrees.
So take off one drive block off the spindle and drive with the other and you can use both BT and CAT tooling....what I did.
edit
You may hear about NMTB 40
NMTB 40 has a threaded female top machined to the tool holder all in 1 piece.
BT 40 has interchangeable "pull-studs"
They all fit the spindle

They are a great mill, I have had mine for about 15 years. The Gorton I-22 Mastermill is built heavier and a little bigger than a Series 1 Bridgeport.You will like it and it will serve you well. I paid $2500 for mine and thought I got a steal. Came with a Troyke 15 inch turntable too. All was in great shape. Good luck with yours.

My family has own three of them over the years. Even though ours were the older 9-J models with No. 10 B & S taper in the spindle, they were a work horse. Talking about high precision, they would give Bridgeport run for their money. They have about 1,000 lbs more iron in them than a Bridgeport has. Wish I still had one today.

Got around to uploading some pictures of the mill. It's stored in a friend's barn.
