Kelp Kritter,
I put my pins back in before I top coat, so the holes are semi-closed.
Maek sure you pin hole is tight, as in drill undersized, and then use a piece of the pin wire to ream out the hole to size.
I leave the pins in when I paint, but don't push them all the way in, so the top of the pins always has some paint on it when I do finally assemble the lure.
If I have a pin that's loose, I bend the top 1/4" a little, so it has to be force into the hole.
I use bicycle spokes, and .072 and .092 screw eyes for my hinges.
BobP,
One of the things using the hinge pin system does is move the pivot point back into the front of each section, which seems to enhance the swimming action at lower speeds.
For me, screw eyes are easier to adjust for gap, and faster than having to epoxy set twist wire.
Also, I'm able to use heavier guage wire for both parts of the hinges.
I started out using twisted sst wire, but moved to the screw eye/hinge pin system, and am much happier with the results.
