So:
Haven't made much priority to finish these straps, even though they are the final parts to this entire trailer and cargo. I guess my my natural inclination to "hit 80% complete and start another project" has now stalled me at 99%. (!!!) Anyway...
Here is the one strap I've made with the new electrical terminals. They work quite well, I just wish the hole was smaller. They bend nicely with pliers, it takes 2-3 secs to get them eyeballed into the pliers. I may not even bother with a bending fixture.
