Gorton I 22 Mastermill Serial #

[63steward]

Hello All,
I have three questions I hope someone can help with;
I am new to the forum and to machining in general, so please bear with me. I just purchased a used Gorton, seller states it's an I 22 Mastermill. I am in the process of getting this monster picked up and brought home, I only have photos, which could be better. In the meantime; 1. I was hoping to run down the O.E.M specs, year built, and model# of machine via serial #, no joy on internet.
It has an original nameplate, Serial # 41183, 3 ph, 3 Hp, 60 Hz. It looks like it is a manually controlled spindle speed, 0- 5600 rpm, per seller. Comes w/ six 9B Hardinge collets. It's equipped w/ an Accurite III X and Y axis DRO and a supplemental motor brake ( "Short Stop"). 2. Can this machine be powered with a VFD? I only have 220 single phase, (sub panel coming soon) in my garage. If so, I will likely get a Lenze SM Vector.
3. Are Brown & Sharpe #9 the same spindle taper as the Hardinge 9B?I am wondering if finding a tool holder/adapter is going to be difficult.
I know that's a lot of info, so any help would be most welcome.

Thank You

Info I see says Gorton's take one of 4 collets: 4NS, 9B, GTM, R8. To answer your question, if you refer to page 44 of this link to the Hardinge info, it looks like 9B is same as 9 B&S.

According to my Machine Tool Serial Number Book, your mill was made in 1960; 1960 started with 41509, 1961 starts with 47059, it was first built in 1955.

Thanks Dan!, I bookmarked the link. On another site someone had mentioned it was better to have a quick change set up, but for my purposes I'm not in a production mode anyway.

Thank You Sir, that's a lot more info that I had before. I'm told they're a solid machine.

The Gorton fisherman owns one of these. He lubes it with cod liver oil.

I have a 1-22 also. I have a Teco VFD on mine.

Here is the VFD.

At one point I had my eye on an 8 1/2D for $900 but I decided a small bench mill fits my very limited space better.

HI Marc,
Looks like he should have used some kind of oil, lol. Little rusty for a California machine. I'll have to clean it up.
