I adapted a Bridgeport style Y-axis power feed unit to my RF30 style mill.
Originally I planned to put the unit on the right end of the table but I discovered that the ring gear fit perfectly over the end of the lead screw on the left side of the table.
So I changed the plan and mounted the it horizontally instead of vertically.
I bored out the round adapter so that it fit perfectly over the boss of the mounting plate that holds the lead screw.
The photo below is just a test to make sure that there wasn’t so much draft on the casting that it would prevent a good fit. I later parted it off where the outside step is in the photo.
There were three holes to mount the ring to the machine and two tapped holes to mount the unit to the ring.
I fussed around till I found a combination that held the unit in the right position, had two holes into the table casting, and two of the myriad of mounting holes in the casting of the drive unit.
Fortunately such a combination existed and it went on perfectly.
I parted off the part of the gear that was unnecessary.
And 3D printed a cover so that chips and what not wouldn’t make their way into the gear.
For reference the unit extend 6.5" past the end of the table. The old handle extended another inch or so.
