The Mother of All Bar Clamps - Philip1231 - 01-14-2022

From time to time, I've thought that it might be advantageous to have a couple deep-reach bar clamps: maybe of a size that could reach half way across the top of my 24" wide bench. I took a flyer on a pair Bessey 24" x 12" bar clamps and was amazed at the size of the them when they arrived. Might be more appropriate for millwrights or boat builders, but I think might get some good use out of them. Tried to capture their size in the pic: they are 16 lbs each. Surprisingly, made in Germany.

How many did you get? I hope you got at least a pair as sometimes one alone can't do the job.

A previous neighbor was a welder and he had a bunch of deep throat clamps. When he retired and moved, I snatched a few from him after some pleading. I would've bought all of them if he had wanted to.

They aren't replacements for the holdfasts and aren't used too often. But they can be a lifesaver!

If yours was the mother of all bar clamps, meet the grandmom: https://www.piher.com/530-large_default/mod-50k---depth50-cm.jpg

I ended up with two: I generally buy clamps in even numbered sets. I will have to start wearing steel-tipped work boots in the shop: would not want to drop one of these!

18th c furniture makers probably didn’t have a lot of clamps. Their joinery didn’t require them. Their glue didn’t benefit from high clamping pressure. The clamps they almost always had were big parallel clamps kinda like these. I built my set a long time ago. They have been extremely helpful but for things I hadn’t initially assumed they were for. I use them for work holding or supporting boards on top of the bench (like the moxon vise).

Wondering if you’ll end up using these for work holding as opposed to glue ups etc. Please let us know.

If you have old furniture restorers in your city or town, some of them should own a few of these deep throat F clamps, made in the US. Nothing else will work as expidently when you try to clamp down on a veneer repair in the midfle of a top that's a foot or more from the edge.
