Indeed. Welcome Rob! All info sounds right. F-clamps will give you about an 1 1/8" of thread to work with, and you'll want to avail yourself of all of it by backing the screws out before hand...and as Okami says, pre-stress the bowclamps by squeezing some of the bow out while setting your clamps in place. I think you can see that at a little at about 1:18 in the video. Takes a little practice, but that will save some valuable thread length (also helps hold things in place).

And as for the tension in tightening... a few drops of oil on the threads will go a long way.

And thanks for your interest Rob. And thank you guys for help chiming in. I'm sure Rob would rather hear from you guys.
