The ideas in this video were inspired by other woodworkers. The biggest influence on the subject is Life Style Woodworker Paul Sellers. If Paul didn’t come up with the idea of inserting a wood core into the bar clamp, then he sure did popularize it.

I have a few of these, along with many other HF clamps. They are really not terrible clamps for the money.
