I’m satisfied with the cosmetics for now. I need some help with the feed screw now. The mandrel spins fine, motor is strong but I can’t adjust the half nut any higher and once you put the arm down it stops the mandrel. Should I try to bend that half nut up a little bit? From searching the forum I see that there should be a slight gap with just a little pressure on the feeds screw. The adjustment screw moves fine but it doesn’t raise it anymore than it is right now without completely unscrewing.
Thanks all for your help! Sorry to keep this tread going.

Looks to me like it has been bent down. You can take the feed nut assembly apart and carefully straighten that flat piece of spring steel. Place it on the top of your vice or some other hard flat surface and lightly tap it until it straightens out. Be careful not to damage the threaded half nut on the other end. Once you have it straight and flat put the assembly back together then you can properly adjust the pressure of the half nut on the mandrel shaft.

The spring does look a little forced as mentioned above.

However The Triumph carrier arm is independent of the slide tube, and it is possibly easier to loosen the screw, in the picture seen projecting at the back of the carrier arm, and then slightly rotate arm on the tube giving the half nut the desired clearance.
A little soaking oil may be needed to loosen the parts before this can be done with ease.
Then clamp the arm back up with the screw and the normal tension screw should be adjustable for the desired result.

I agree totally with the above. In addition, after you get the tension correct, lower the carriage until the half nut engages. Place your thumb over the half nut and at the same time, loosen the two screws holding the half nut bar to the carriage. Wiggle the half nut around slightly until you're certain the the nut is well seated/meshed with the feed screw threads. While still holding the nut down with your thumb, to maintain alignment, tighten the two screws again. This ensures that after the other adjustments you made, the half nut is still engaged properly with the feed screw and not cross threaded or touching only at one end or the other of the nut.

By any chance can some one look at these pictures of the position of the brake . I have been adjusting it but the best I can get it to work is that it will stop it if the spring is almost run down. I am thinking my problem isn’t an adjustment with that lever but the positioning of the actual brake itself.

Could the flat spring be weak or badly adjusted? How are the brake pads?

Thank you all for your help. I was traveling for a few weeks for work but was able to get the adjustment screws off with several applications of Zep and blow dryer heat. It is working and playing now. I am excited to get a recorder and some blanks and try my hand at some low tech home recordings. This machine is perfect for me as I can play 2 minute and 4 minute cylinders and possibly later record some cylinders all in one machine. Many thanks to the board where I was offered this machine and the advise to get it running, and luck into a Triumph horn from Dustin not more than a week after buying the phonograph.
This was a lot of fun, it was very dirty, grimy and the feed screw didn’t work but after getting it up I really appreciate all the help along the way
