Question: Will a 5' pipe and these clamps work for a 54" table?  In other words, how much pipe does the clamp occupy?  If less than 6", I should be good.
Document: This pipe clamp set is built really well. Feels heavy-duty, including the all-important crank/screw portion. It's even more sturdy than the Pony clamps that HD sells. I got it for a few dollars less through Amazon, no less.The legs on the bottom are priceless detail. It's so easy to set up the clamp on the table, bring the work piece onto it, then tighten up.One thing to note about pipes (obviously not included).
Pipe clamps sometimes get a bad rap...sort of the grunt way of doing things. But with the feet on these Bessey clamps providing some clearance from your work table, bench, the ground, or whatever, I find these have a slight advantage over some other clamp styles. Add to that the ability to use this clamp at virtually any size/length, and at a good price...that's a good package.
I made the mistake of buying  dozen Irwin clamps before I tried these. I was so happy that I bought 2 dozen Bessy's after reading the reviews, which were favorable (not just Amazon reviews) that I will be purchasing another dozen. The feet have a much wider stance than any other clamp I have used and the clearance of the handle to the table is at least 3/8" more than the Irwin's (I did measure them).
These clamps work very well, slide and maneuver well, are very well built with thick iron/steel, and offer great clearance from the table when using them in the upright position. The screws are smooth with the crank handle attached very firmly. I also REALLY like the rubber padding on the flats. They have a very good paint job on them too. It helps keep your work from getting scratched up when using them by themselves.
Black pipes can leave a dark residue on your work piece when it comes in contact. That might give you problems when you apply finishes. At my local HD, galvanized pipes are only slightly more expensive than blacks. Well worth the price. Also, buy 10' sections and have them cut it to size that you need. You'll notice that 10' pipe doesn't cost that much more than 3' or 5' pipes. Have them thread both ends.
It's a pipe clamp. The only way for a manufacturer to mess this up is with lousy castings or machining of the threaded end and the tightening screw and threads;  Bessey got those right. If you know anything about pipe clamps you probably know that bigger is better--that is 3/4" pipe is better than 1/2" pipe. At Amazon, the bigger/better model even costs less than the 1/2" model.
I own several types of Bessey Clamps. I bought these to increase my collection of 3/4 inch pipe clamps. These work right every time. The crank handle allows hard tightening without strain on my hands. The feet keep work up off the table. The rubber pads are great protection for the wood being clamped. I have used these for clamping cabinets made of birch, cherry, and poplar without trouble. I also have the 1/2 inch for smaller glue ups.
These work great. I also have a set of the 1/2&#34; clamps which I bought in a fit of cheapness. I have now gone back and purchased their big brothers. These are much sturdier than the 1/2&#34; clamps. The smaller ones were subject to bowing of the pipes when I clamped large projects (over 3 feet). These don't have that problem.Don't cheap out. If you need pipe clamps, go ahead and get the big ones.
These pipe clamps work smoothly and are fairly stable. In use I've found them to be easier to use than my bar clamps because they move into position much more easily. They are worth more than the lower cost bar clamps because of their stability and ease of cranking.
These are very good pipe clamps. With the feet on them it is easy to set them up and lay your project in them prior to closing the clamp. Several different lengths of pipe make them usefull on any size project. I recommend them to all woodworkers.
