A couple of pin spanner wrenches over the weekend. The Black one is for adjusting the King Shocks on a Tachoma pickup, very tight fit and not much room to rotate. The shinny one is for my 5C Collet holders securig nut. Lay out was done on 1/2" and 3/8" hot rolled steel then rough cut on the bandsaw then machined to clean up. The black wrench, the handle was tig welded in position. The pins for both were made from 3/8" stressproof steel, threaded on one end and sized for the hole on the other. Both fit and work perfect.
