Chopping copper

These are the pieces of 3mm copper you'll need to solidify the spindle, h-shaped cradle, pin and u-shaped rest.

Try to use copper, brass or something similar. Stainless 3mm steel is a pain in the arse to cut, for no benefit.

  1. Cut a 70mm long pin for the spindle, and push it through the centre-hole
  2. Get a 20mm long pin for the pin
  3. Well, a 40mm long pin for both the cradle and the rest will do just fine.
