Acme threading

Is that nut for a 9-J Gorton mill?

I did just like you did, make one from scratch. I also made a new cross feed screw, worked out nice.

This was 30 years ago, still good as new when we sold the mill several years ago.
 
Hi Ken,

Yes that is a new Y nut from my 9J Gorton. I was calling it an X but had my head up me arse. You could just about cut paper on the old screw threads. It's much tighter now. I got the gear cluster back in yesterday, but the idler gear had a bit of a chatter and wouldn't lock in properly in the third speed range or on the 35 tooth gear. Later found out that my friend that made the cluster for me needed to cut the small gear 20 tooth, next gear 27 tooth, next gear 35 tooth and the big gear 43 tooth. He cut the 35 tooth with 37 instead. Thats why it wouldn't lock in properly. I removed them from the gearbox and was making a mandrel to take the cluster apart when my wife asked me why I was making a mandrel. She said she would get me the one they used to make the cluster, so I came into the house and sat on my butt. Ok by me!!! LOL

Patrick,

Thanks for the reply. Just wondering, the beveled gears or miter gears in the bottom of the gear box where the motor input shaft comes into the gear box, were your's in good shape. One of the Gorton mills we had, that gear was in bad shape. We never replaced it. Since sold the mill and just got it back on a horse trade just recently. Now, we're more than likely, going to have to go in and replace that gear set. For a 1938 model mill, it's still in good shape. The monster spindle motor is about gone. We're going to replace it with a smaller size motor same HP and put a vfd on the mill. That'll also keep us from having to change belt speeds and also allow us to get down to the lower RPM's we couldn't get to before.:thinking:
 
Ken, all the gears in the gearbox were in really good shape except for that gear cluster. The guy I bought it from said he only ran it in one speed and didn't say why. I discovered, when I got it home, the reason. The motor was also running backward compared to the spindle motor so when I reversed the table motor, it locked up. That is when I discovered the gear problem. All in all, it has been a learning experience. I don't mind repairing equipment to get it back operational. I repair equipment on my day job and to me, fixing my own stuff is rather enjoyable since I'm not in a hurry to finish and not charging the customer by the hour, since I'm the customer. Also, going thru this mill like I am, I can really appreciate the quality and workmanship that went into this mill. It is a damn stout machine.

Be sure to install 6 penny nails in the shear mechanisms for both feed screws and nothing bigger!!! If you didn't know that when taking things apart.
 
I'm glad you said that. I've been using ally rivit shanks and they don't last very long, but thats what the other guy was using. That was the one place I screwed up the Y screw, trying to line up the holes for the shear pin. they aren't lined up perfectly, but they do go thru. I just have to drive it in with a hammer.
