Spin it Again! - Budget Weld Rotator Build.

admin

I thought I could transform this pile of stuff into a weld rotator table. Attachment 13671 However, after reading the rotator posts at weldingweb.com, I decided it wasn't the way to go. Thanks to all who have posted their rotator experience.My new simpler design is a right angle speed reducer, 60:1 ratio. I now have the reducer bolted to a 6" angle bracket, trued and tack welded to a 12" channel base. Took it for a test spin today. Attachment 13673I have not made a final motor decision, but table speed seems to check out okay, with the drill motor at low speed, 0-600 rpm input.The work "turn-table", will probably be welded to a keyed hub or sprocket.Thanks for your thoughts, especially about a drive motor.Last edited by denrep; 10-19-2010 at 11:20 PM.
Reply:Looks like your getting there. I suppose something in the DC world would be the best motor. Something that doesn't snap or coast, capable of variable input?? I can remember years ago the old ham operators used the old prop pitch motors scrapped from WWII planes. They used them to turn their big beam antennas in fine increments.
Reply:Hey denrep,My riding buddy made a turntable for a fellow he works with and used a "Tenna-rotor" from his old tv antenna. He got the electric shop to reconnect the control box to a footswitch and direction toggle so it would turn in both directions as the control did. Surprisingly, the old Tennarotor's had quite a bit of torque and since the tubing he was welding was never over 25lbs, it worked well. They made a spring-loaded ground brush on the underside & lug for the ground cable. I'll see if I can get him to take some photos for me......DennyComplete Welding/Machine/Fab.
