Now I’m feeling guilty for not taking photos during construction, so here’s my shop notes in case anyone wants to build something similar:

Specs 
  • 2 1/4” x 3 1/2” x 1 1/8”
  • Shaft is 3/4” x 3/4” x 8”
  • Thumbscrews are M6 x 16mm
  • Finish is Osmo Polyx


 
Body 

  • Body is cut into 3 pieces, middle piece is 3/4” tall
  • Middle piece is cut in half and 3/8” removed from both inside edges so that grain will match back up when assembled 
  • 1/4” through hole drilled in center of top piece for screw, then 3/8” hole drilled deep enough for M6 brass insert. Larger hole drilled from bottom of top piece to accommodate small plastic bumper adhered to a washer 
  • 3 pieces are glued back together 
  • Grooves are cut for brass inlays, inlays epoxied in place 
  • Run through drum sander to flatten evenly 
  • Cut curve on top using bandsaw, clean up with belt sander 
  • Sand lightly to avoid gauging wood up to 1000 grit 
  • Chamfer edges 


 
Shaft
 
  • Rout shallow 1/2” groove on side with end of ruler (zero) 1 1/2” from front end of shaft 
  • Drill 25/64 hole for pencil centered 1 1/2” from end to line up with ruler 
  • Drill 1/2” countersink from side 1” from end
  • Drill 1/4” through hole in the same position 
  • Drill 3/8” hole from the other side in same position to accommodate brass insert
