I really want to get this done since it would be so handy. Do you find the set screws are holding just fine? I was thinking of using a roll pin to pin the adapter to the leadscrew.

Ed,
My installation has been in use for two years and I have had no problems. I was able to get a very close fit on the bore which is important. The set screws hold fine. I didn't consider any other method of holding the adapter in place. My original handle had a roll pin through the shaft but in typical off shore fashion it ws drilled off center and crooked. I would have been tough to put a hole in my adapter to match the crooked feed screw hole.
I must confess, I started three adapters and messed up the first two before I got one that was good. When I was threading the third adapter, I was very nervous because it would have been easy to mess up yet another one and loose hours of work. I should also mention that I had to fiddle with the spacing of the gear using the assortment of shim washers supplied with the power feed. I use the power feed ALL the time and it makes a much better fly cutter finish than I can do by hand cranking.
Have fun mounting your power feed. You'll love it once you you get it going.

Ed,
One other thing that is important. Your large dameter length of 3.250 is fairly critical once you mount the adpater to your lead screw because it sets the mesh of the pinon gear to the ring gear. To a point you can move the ring gear out using the supplied shims but it should be close. I had to remove my adpater and take just a small amount off the face of the large diameter to move the ring gear in just a bit. I ended up only needing a small amount of shim.

Yup, I realized that yesterday while I was staring at the drawings so I got the power feed out and took some measurements and had to change some dimensions on my drawings.
I need to fix my cross slide movement problem before I tackle this project though.
