CNC Hold Down

This is a flat top LP body I started long before CNC was even a twinkle in my eye. SO the big question is - how do I hold it down while I machine it? I decided to make a one-time use fixture out of MDF.

I double-stick taped it down to the top of the body. Notice the cut-outs so I can line the body center line up with the machine.

Then I used several really long screws around the edge to hold it down to the scratch board.

The cut-out area is where the machine has to cut deep and I don't want the chuck running into the MDF.

Success!
