The 1/4" _is_ the advantage.
Larger pipe is stiffer, so longer clamps stay straighter under pressure.
I'll bet the fatter pipe also provides more gripping area for the
movable end of the clamp.
So, I guess bigger and stiffer pipes are better. =8^0
Not in the sense of bending it *permanently*, no. But they *do* flex
noticeably under _normal_ clamping pressure, and 1/2" pipes flex more than
3/4" pipes do. This is a bad thing, because when the pipe flexes, the clamp
jaws are no longer parallel to one another.

I'm not sure I agree, depending on the set up.
But there is another reason for wanting a lack of
bending. On big glue-ups the pipe clamps may be
sitting on a surface--floor, table, or sawhorses
with supports 6-10 feet apart. The pipes can
contact the boards, hopefully with wax paper
between the board and the pipe. A straight pipe
is highly desirable. A 8 or 10 foot length of
1/2" pipes will likely end up with a bow, while a
3/4" pipes will remain straight even with some

None, they're too heavy and can easily apply too much force. I bought
3/4" clamps and now regret it. Wait for their half inchers to go on
sale, or better yet, wait for the Pittsburgh bar clamps to go back on
half price sale.
Caveat: Do NOT buy the Central Forge brand. Pittsburghs are lifetime
warrantied and are much better made.

I don't get it. YOU control the force applied (and you can easily
apply too much force with the 1/2" size as well). Other than the
extra weight, I can't see why a 3/4" clamp wouldn't always be

The one I just got is taller than the others and causes some alignment
issues if not used on the TOP of the work.
I would clarify that!
The 1/2" clamps are plenty rigid for shorter pipe lengths. I have a dozen or
so three foot, 1/2" clamps. Personally I would not go over 4 feet in length
with 1/2" pipe clamps. I also have a few 3/4" clamps with pipe lengths in
the 5-6 foot range.
Oh my! Did anyone actually buy these? I got the bug.
The first one to come out of the box is completely split on the handle
where it was driven onto the screw.
My first, and possibly last, HF experience.
Yep - I bought some, mostly because I've seen several posts on this ng
that say they're not too bad (As long as you get the "heavy duty"
kind). I haven't put them on pipes yet, but they look fine - no cracks
or visible defects. HF is what it is - cheap stuff direct from China -
don't expect the quality control of more expensive brands. However, as
long as you keep your receipt, they're good about taking back defective
stuff (IMO). So just be sure to check stuff out carefully before you
buy it, keep your receipt, and it is possible to save a lot of money if
it's just something you'll use occasionally. One thing I've heard here
(and experienced) is to avoid their sandpaper/abrasives, no matter how
cheap they are.
I grabbed a couple, just because I was in the store getting something
else, and they don't have any problems that I can see. I haven't used
them yet, but I did take them out of the package and give them the
once over and they seem fine.
