This massive and strong extension matches the design of the Delta bed and Midi lathe. Unfortunately, the B-pillar adjustable leg was not threaded well and the threads did not match the leg screw. I had to press again. The parts are not precision made and required multiple attempts with repeated adjustments to put them together. The extension joint was 1/16th from the main rail, allowing the tool rest and tailstock to hang from the joint. I had to file them to ensure smooth gliding. In the end it works well and allows me to flip longer pieces.
