Rotary table power feed

[Charles scozzari]

Hi, just would like to show my table feed unit using a mill table feed for rotating my r/t. My first idea was a belt driven affair that worked but in order to reverse the rotation I had to twist the belt into a figure 8 as shown in the pictures. Above all I knew I was placing a hard side load on the worm gear bushing of the r/t. The latter pictures are my latest attempt. It works nicely and has a wider speed range. I had to rotate the feed 90 to clear the table knee. Now when I clean up 18"x1/2" diameter plates the finish cut is clean. Thanks for looking, Charlie.

That's a great idea and gave me a use I hadn't thought of for an Align unit I have. It is missing the adapter for the cross feed on my Bridgeport and haven't spent the money to obtain the missing parts due to figuring I don't need it that much. But I would use it on the rotary table much more.

Questions
What type of adapter did you make to drive the handle on the RT? Looks like it may be just an added flange, bolted to it. But how did you drive that flange?
Also looks like you maintained the hand feed crank. Does the drive add much if any resistance to hand cranking?
Any disadvantages you have found?

Thanks for the great post

Good morning Aaron, I will get back to you with photos of the adaptor in pieces no later then tomorrow. I'm on my way out, but will absolutely get back to you. As to your question of hand cranking, no resistance at all. Charlie.

Good morning Aaron, can you tell me what brand rotary table you have. I set my drive up on a H/V 10" Vertex. If your table is another manufacturer I will still send all my measurements as a guide. If that's the case it still can be done. It was actually straight forward and easier than I thought. Bring up my photos as a guide also. I will be stepping out again for steel needed for a job, but will get back to you. Thanks, Charlie.

The RT brand is a Chinese knock off But looks just like a Phase 2 10". I mainly just want a look at the part you made to fit into the PF. A picture would be great!

Hi Aaron, Here are some photos that I hope will be of some use to you. Please let me know if they were helpful. Sorry for all the time delay. Charlie.
