Well after about a year & a half I finally finished up the rebuild of my Fray No. 7. I hauled it out of the West Virgina panhandle about 5 years ago and it had to sit while I built my shop, added a garage bay onto the house and a few other items.
BTW, I paid $400.00 for the machine and I probably put another $400.00 in it including the new main motor. The feed motor is a old compressor motor I had on hand.
Originally it was a 3 phase machine, but only had a 1/2 HP main motor. So I bought a single phase reversible 1 1/2 HP and made an adapter. I also replaced the feed motor with a 110V single phase motor.
Most of the mill was there. The feed screw for the "extra" X axis had been cut off, so I had to stub it and I had to make a bearing housing for said screw.
The most difficult item to replicate was a dial. Turning, boring, etc was straight forward, but engraving the lines was a challenge. I never mounted a rotary table on a faceplate on a lathe before, but this was the only way I could cut the lines with the equipment I had on hand.
I did a complete tear down and striping. I sandblasted all the castings, primed them and then applied five finish coats of Rust-Oleum industrial grey paint. I also built a reverse electrolysis unit big enough to hold the table. It sure was helpful in rust removal.
During the rebuild I did not have access to a mill, so I ended up going back to my apprentice days and laying out, sawing and drilling most of the features on the main motor adapter. Once it was partially rebuilt and usable I was able to mill some features such as a keyseat in the stubbed shaft, drilling & tapping holes for Dutch keys in the new gears and the bolt pattern in the feed motor adapter.
Speaking of the replacement gears since I did not have a mill available I bought two gear blanks from Boston gear and modified them to fit. It turns out the feed unit was made by Bridgeport in the late 1950's as was the head for the mill. I found a BP manual online that gave me the drawings for the feed unit.

I could not figure out how to rearrange the album pics so it is not in proper sequence.
