Transformer Re-winding Mandrel 2" x 1.25" x 1.625"

Mandrel for re-winding Output Transformer from Leslie 122 valve(tube) amp, or any transformer with 2" x 1 ¼" x 1 5/8" core. Mounts on 3/8" shaft or 3mm screws to flat plate. This could be remixed easily to mount on other coil winding machines but I included a pair of 2.5mm holes threaded to 3mm - each located ¾" from centre - to screw it to a face plate rather than mount on a central spindle. The 3/8" hole might need to be reamed a tad.

Printed in PETG but should work fine with PLA etc. - no supports required if printed with flat mounting face down.
