True that if our jointery is perfect, you shouldn't need much clamping
pressure. But what if you should screw up . . .er. . .I mean if your joints
are a little less than optimal? You just might need a farking but-load of
clamping force. Or if your wood has a slight twist, warp, or cup. Not
everyone can afford the luxury of thickness planers and jointers, etc., and
not all wood is flat and straight.
I cannot remember having 2' or 3' pipe clamps bend enough to be a problem
(using 1/2" pipe), but I have had 4' sections bend a little. And there are
even some possible cases where the bend can be beneficial. For exmple, I
was building a shelf unit that had dadoes cut in the sides and back for
shelves. When I used a clamp across the back of the carcass, it bent and
actually helped to keep pressure on the center of the shelf itself. In
other words, it made sure that the back did not bow outward away from the
shelf. But overall, I would say that the stiffer the clamps the better so
go with 3/4" pipe.

Or the patience to re-do the "less than otimal" workmanship so
excessive force is unnecessary. To each his own. "If it doesn't fit,
use a bigger hammer" is something it took me a long time to outgrow,
so I really understand. :)
In my original reply I was careful to say that I thought 3/4 to be
overkill for "fine woodworking."
We're talking about two different types of building here. If I'm
using undressed lumber that's crooked, bowed, warped and/or cupped,
I'm generally building outdoor play equipment and lawn furniture, not
furnishings for my home. :)
I've done a bit of that, and I've used the scissors jack out of my car
as a clamp, (or, more accurately, a spreader), too. The right "tool"
for the job, eh?
Hope I used enough smileys.
I have been cleaning up my workshop/garage lately. last night I counted up
I have >50 spring type clamps of various sizes, but only about 30 clamps of
other type. Amazing how one accumulates such things over time. i would
never have guessed I had more than 80 clamps.
If you want to save money on good clamps:
I got a bunch of their stuff and it is all good, expecially the price.
Right now, free shipping on an order of $100.
Be sure and check out thier "web specials" They put stuff on sale all
I have not bought a clamp in a retail store in years.

I have some of each. Got the 1/2" when I was young and broke. I still
find uses for them from time to time. Unless the above description fits
(young and broke) you can use a 3/4 for anything you'd use a 1/2 for but
not necessarily the reverse. I picked up a few 3/4 sets from Rockler a
while back that have the bracket on the back that keeps the jaws level.
I also have a few bar clamps of various types. Have you been thinking
about Besseys? Pipe clamps have the advantage that in an unexpected
situation you can use very long pipes, you can use couplers, you get the
idea. A few are always nice to have around. Other things being equal,
I'd go with the 3/4.
