Checklist for using the Bridge City JMP2 to cut “through” dovetails

I have compiled the checklist below to make it easier for me to remember how to set up and cut through dovetails on the Bridge City JMP2.   The Bridge City YouTube video on this process helps (embedded below),

….but it is quicker for me to just look at the list below to refresh my memory without watching the video…I guess I am more of a checklist person than a video person….old school.

The checklist is written by me for me, so some of my shorthand and notes may not be so self-explanatory.  Use at your own risk.

Checklist for using the Bridge City JMP2 to cut “through” dovetails

Process checklist (version 11/25/2011)

  1. Cut tails first
  2. Set blade to 8:1 tilt and to wood thickness (tilt blade sloping up and to the right)
  3. Strike lines with marking gauge (Tite-mark) on all both faces of both pieces.  Mark the pieces as “inside and outside and pins and tails” with pencil
  4. Cut just slightly “deep” (more than wood thickness by a couple thousandths)
  5. Clamp stop block onto fence to allow for repeatable cuts
  6. Cut tails (one cut then flip block then move stop block toward center and repeat with flip)
  7. Move blade to 90 degrees
  8. Cut off shoulders
  9. Chop out tails (chop ½ way through and then flip and complete)
  10. Mark pins from tails onto 2nd piece (lay newly cut piece on top of 2nd piece).  You are marking onto the OUTSIDE of the 2nd piece
  11. Leave blade at 90 degrees and wood thickness exactly
  12. Set fence at 8:1 angle (sloping down to the right side of the JMP)
  13. Cut 2 cuts on pins pieces using marks (leave fat – cut on tail side of lines). THESE TWO CUTS SHOULD BE CUT #4 AND #2 COUNTING FROM THE RIGHT SIDE OF THE JMP
  14. Switch fence to 8:1 angle in other direction
  15. Cut other 2 cuts. THESE TWO CUTS SHOULD BE CUT #1 AND #3 COUNTING FROM THE RIGHT SIDE OF THE JMP
  16. Chop out tails using fretsaw and then jig and chisels (chop ½ way through and then flip and complete)
  17. fit

Note pencil lines on saw table that make setting the fence angel for 8:1 dovetails faster and more repeatable.
