Kind of an FYI for anyone considering a pipe clamp purchase.
I'm finally getting around to putting clamp heads on a stack of pipe that I acquired in a buyout. Most of what I already have is Pony, which is no longer an option, so I ordered one each of Bessey and Yost from the big A.
The Bessey has huge standoff feet that seem really clunky to me. Also the casting, while being clean and refined looking, seems light and the jack screw is probably only 75% the size of my original Pony clamps. My overall impressions of this and another Bessey product I purchased, and handling them at a big box store, is I find them disappointing for the price. The Bessey did come with clamp pads but I use cauls so they don't benefit me.
The Yost is clearly a Pony clone. The castings are the exact size and configuration of the Pony as is the jack screw. In fact the casting number on the crank handle is the exact number as is on my Ponys. The only difference I can see is the castings are a wee bit cleaner and say Yost instead of Pony. Oh, and they are blue instead of orange if color coordination is important to you.
Unfortunately both clamps are made in China whereas my original Pony clamps were made in USA. Price on the Bessey was $13.97 vs $11.99 for the Yost. Either one is plenty cheap enough, especially when compared to a parallel clamp (and I already have the pipe), but the Yost just seems sturdier.
