As a professional carpenter/woodworker for over 30 years I have held workpieces to my benchtop with a series of clamps, vices, bench dogs, and hold downs.  What I needed was a miniature hold down that would stand the test of time.  Bobbly pins have been around since the turn of last century that is where I went to find my solution.

First take a metal bobby pin and cut the ends off leaving around three quarters of an inch and open the bend to less than 90 degrees.  That is your old fashioned hold down.  Now onto the next step…

Cut power = 95 Speed = 13

Engraving power = 50, Speed 80 @ 150 Lines per inch bidirectional.

Make sure you set the layers to engrave first!

I have included both XCS and Lightburn files that may be used to cut and engrave the support pieces that snuggly fit between two slats at their closest slots with the P2.  Note how I have arranged my workbed which I have found to be optimal for the cutting and engraving I do regularly.  

The pieces will need to be glued together (make sure you do not get any glue in the engraved slot) in order to provide a square hole for the bobby pin to slide down.  Grab two of the slats and orient in such a way that you pinch two of the cut clips between them and then insert to your P2 slat slots (say that three times real quick).  Use as many as you want to hold your workpiece making sure you push the bobby pin down over the material so it fits with a little tension where it will bind inside of the engraved slot to make a hold that will not let go until you break the grip.

This process uses cutting and engraving.  The obvious cutting is the part itself and the the engraving actually cuts and very slight groove on the inside of two parts that when glued together create the hole for the bobby pin hold down.  

Cost…negligible leftover scraps and the bobby pins are always laying around the house…under seat cushions, bathroom floor/drawers…heck I found mine the kitchen junk drawer.
