I Want To Build A Rotary Welding Table

admin

Show me your power rotary table.  I 'm looking for ideas to weld 36" dia. farmer wheels down to 2" weld in hub sprokets.  Foot pedal & micro switches.  Weight on the table is max. a 150lbs.  Bearings , VHD's, gear reducers, wrecking yard transmissions, or ?   I got  2pcs. of 34"dia. X 1/2 " plate  to start with.  Show me your ideas.  Thanks to all that reply.

Reply:Variable speed reversable motor with gear reduction.  Car rear end will give you a  right angle drive and handle the thrust load form the project and platform weight.  Primary speed reduction with a belt drive.  Variable speed DC motors and controls can be had from the tread mills I see on Craigs List.  The industrial turn tables I have repaired had three phase motors with Variable Frequency Drives.  They also had slip rings for the ground lead.  Backlash should not be a problem with a constant speed drive.Last edited by nadogail; 04-21-2011 at 12:59 AM.Reason: spellingI offer three choices: Good, Fast, & Cheap.

Reply:The new application of our old turntable is to have the frame, motor, etc. in a pit to have the surface of the table flush with the floor.  It buys us an extra 2 ft of headroom under the penthouse.  The table is 12 ft diameter made from 1 in plate with removable 1 in plate corner pieces so the pit can be square.  The controls are on the beam next to the table.We just installed it over the winter and have yet to put a tank on it yet.
