drill fixtures
I finished my drill fixtures. I made one for 3/8" and one for 17/32" (that is the hole size needed for the 3/8x16 nutserts). I also turned a 3" long pin to 17/32 and down to 3/8 for the last 1/2". Now I can clamp the 3/8 fixture to the FRP and frame tube then drill a 3/8 hole through both. Remove the fixture and countersink the FRP so the screw will be below the surface. I will need to do all of the holes for any given sheet of FRP and then remove the FRP. I will then have several 3/8 holes in the frame. I will use the pin through the 17/32 fixture and into the 3/8 hole in the frame. This will locate the 17/32 fixture and I can clamp it in place. Next I will remove the pin and drill out the hole to 17/32. I tested it on scrap and it worked great. Now I will be able to install all of the nutserts and replace the FRP and with some luck all of the hole will line up with the nutserts.
