There are several places in the build, where there is a doubler with a rivet at the end, and plans call for the doubler to be trimmed to a quarter inch around the last rivet.
I used to cut the taper, then mark the curve around the last rivet, rough cut, then get at it with the sander to get the finished product.
While it worked ok, I never got a perfect curve.
Tonight I had a little time on my hand, and played around with this setup - worked perfectly out of the box.
DISCLAIMER: I have not looked to see if others do something similar - so if this is a d'oh post, sorry...
so, step 1, take a flat bar, drill a hole near the edge (maybe one for -3, and one for -4 rivets), then clamp it to the sander table. Distance from center of hole to sanding disk should match your intended radius.
Put your piece in, insert a rivet, fire up the sander, and around you go. All you have to do is kinda rough cut to minimize sanding, and your starting point needs to be at the right distance.
Did a scrap piece to test it out.
