Lathe Banjo Lock

Build a wood lathe banjo lock.

Scribble some ideas.

1 bolt, 2 nuts and a washer.

Cut a 2x4 to size and drill a hole in the center.

Fasten the bolt to the wood so it protrudes from one side and tighten.

Fasten the lock to the banjo. Use a wrench to tighten. If you want a more durable lock with greater movement another design follows.

Bolt, nut, round washer, square washer.

Mark the washers for resizing.

Saw or grind the washers to size.

Fine tune the shape of the washers to perfectly fit the lathe bed.

Weld the two washers together. I cold welded with JB.

Weld the nut to the bottom of the square washer.

This step is optional. I found the unit slid on the bed better with a fabric layer. Epoxy thin felt to the washer surface and trim.

Cut some metal to size and use as a finger lever. This avoids the necessity of using a wrench to adjust the banjo.

Round the edges.

Weld the pieces to the top of the bolt head.

Put the lock to use and work out any bugs.
