These clamps appeal to many woodworkers, and they certainly have their place in any woodshop. But, if I can get a Bessey on my projects (up to 80") then that's the clamp I reach for. However, they are not perfect.One problem is that they have a tendency to pull frames out of square, and or put a bow in your glue ups if you're not careful - which is really not a problem of the clamp itself, but the flexing of the pipe. Do not buy these clamps in the 1/2" variety for any length over 4 feet.I own and use these clamps and I wouldn't be without them.
THIS CLAMP IS TIME TESTED AND HAS ALWAYS OUT PERFORMED THE OTHER BRANDS. I HAVE BEEN USING PONY#50 FOR 35 YEARS,AND WON'T PURCHASE ANYTHING BUT. THE SECRET IS A BETTER RELEASE ON THE FOOT PORTION OF THE CLAMP.
manufacturing when possible. With an investment of $12 per 72" of galvanized pipe at Sears, I had solid, long clamps for $27 apiece. I am not sure why Jorgensen recommends black pipe; it may be a perceived cost difference. I cannot speak to the Bessey equivalents (which I suspect are good as well), or the many cheap no-name versions of these, but I trust the Jorgensen name and am glad to be able to support U.S. These clamps are a real bargain, and in spite of the low price you simply do not sacrifice anything in terms of performance.
Also, per the excellent suggestion of another reviewer, I attach rubber walking can tips on the exposed pipe end, which does prevent inadvertent marring of other surfaces and protects the thread from damage. I needed a set of four 72" clamps, and these are really the only option. I have one suggestion for these: although the manufacturer recommends black pipe, I use galvanized instead. Awfully hard to beat. I clean the pipe of residue with turpenol (any solvent/degreaser would probably do), and I do not have the issue of making marks on the wood surfaces.
I had to buy these from America, Turned up after 2 Days. Great product and service.
These work great. They are easy to switch from one pipe to the next so you can have various clamp lengths by having a different pipe lengths available. just buy the length of 3/4 inch pipe you need and you have a great clamp.
