I have used the truck tie downs for band clamps many times. I use them with cauls when gluing/repairing odd shaped pieces. Not my idea... I read about it somewhere a while back.
Then I got the idea of using the ratchet style tie downs to glue bigger things. Doors, gluing long trims to surfaces, indoor/outdoor furniture repairs, etc. Anything I couldn't quite get easily with my current clamps. For me, the ratcheting tie downs turned out to be much more handy as clamps than they did tie downs.
See if you can find the small ones that don't have the hooks on them. I had some with 1" wide light weight straps (500# work load / 750# break) and they were flexible enough to work great.
One of the first things I glued back together with was an oversized door. I didn't have by big clamps with me and this was a custom made entry door that was 40 inches wide or some such. As the main entry it was beat to hell and the bottom rail/kick panel was loose and coming off.
With the door laying flat on the horses, I glued up the joint, and put a straight piece of 2x4 that spanned stile to stile on edge on both sides (loose, I had a helper). The 2x4 on each side was there to make sure I didn't bow or cup the door, or make a crooked joint. That's why it was on both sides spanning the stiles.
I put the nylon ribbon of the clamp on the edge of the 2x4 on both sides. Clamped it up with the ratchet, then ran a couple of 3 1/2" deck screws from the bottom of the kick panel into the stiles and left it overnight.
It didn't flex or move a bit. The 2X4 spines did the trick.
The best thing about these little ratchet clamps as opposed to something they sell to wood workers is the price. I paid something like $4 a piece in a four pack at a hardware store. If the same clamp, a "multipurpose flexible band style clamp for fine woodworking" is sold to the woodworking community, they would surely be $20 a piece.
