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.
