If you think those are overpriced then check out these babies, they're
triple the cost and they still don't come with clamps.

Aha, that explains why no matter how many times I measure the pieces of wood
I cut up never fit, it's a multiplicicational thing. ;^)

Good tip, thanks. I see Jevons is an exhibitor at the woodworking show,
I'll keep an eye open for a deal such as you got.

I have two pair and have used them a few times.
Don't rely on them to keep something at 90 degrees. They're more for
general positioning.
The aluminum ones are a better bet for accuracy.

Now these look a lot better. Outrageous cost, though.

I bought two of them years ago. Nice heavy duty gizmos. For them to
work halfway decent you have to have one on every corner. The clamping
pressure is very limited in area. They are not worth the money they
cost.

I have an aluminum supplier/distributor in my area and they have
ARCHITECTURAL shapes (square corners) that work well for jigs and
such. Mine has a CUT OFFS box where I can buy scrap pieces by the
pound. Made a ROuter Tabke Fence out of one piece and a tenon jig out
of some two-ich square stuff.
PS, eve if they were "square" as promised, ten bucks is way too much,
way too much.

I can't advise you on the use of these clamps, but I did consider them and
decided to go with the swivel mitre clamp.
http://www.leevalley.com/wood/page.aspx?c=2&p=31165&cat=1,43838
I figured I can only work on one corner of something at a time and if I
ever do need to partially assemble something before putting it together
permanently, the 90° assembly braces I bought will do what I need them to
do. http://www.leevalley.com/wood/page.aspx?c=2&p=51101&cat=1,43838

Especially considering that the ones from Rockler have only a passing
acquaintance with "square".
To anyone who is considering buying the Rockler "Clamp-It", I suggest visiting
a Rockler store. Take two of them out of their packages, and set them on the
flattest surface you can find, such as a jointer or table saw, butted against
each other like so _||_ and check for gaps. Typically, you'll see about 20
thousandths.
I once made the mistake of buying a set of four of these without checking them
out first. Once I got them into the shop and checked them, I was appalled.
They're advertised as "perfect 90 degree angles" but they're not even close.
Depending on how I paired them up, the gaps ranged from 0.020" to 0.035",
which means that they're inconsistent on top of being inaccurate. When I
returned them to the store, I took a set of feeler gauges along, and checked
about half a dozen others without finding any two that would produce a gap of
less than 0.015".

Yes, a couple of things:
- wood flexes (although this can be mitigated somewhat with triangular
gussets, solid joinery, and proper attention to grain direction)
- wood changes dimension, and therefore shape, with changes in humidity.
That said, if you have good tools properly set up, it shouldn't be too hard to
make your own out of wood that are at least as close to square as the junk
from Rockler.
Or you could get these
http://jevonstoolco.com/_wsn/page3.html
and not have to worry about square ever again.
I bought a set of four at a woodworking show for $39.99 a few years ago, and I
recommend them highly: stiff and rigid, and even more accurate than
the advertised tolerance of 0.002": set against each other as described above
on the bed of my table saw or against the blade of a Starrett rule, I am
unable either to fit a 0.002" feeler gauge between them at any point, or
indeed to see any gap between them at all.

Same as I used. Made a set of 4 triangles from 3/4 birch ply scrap,
8 x 12" each. Drilled 1" holes along the bases and verticals to
take F-clamps. Notched the square corners to let glue run.
Wax finish was enough to pretty them up.
Surprisingly, they came out square enough that they themselves
can be used as squares.

Maybe, but I bought a pair of them anyway and don't regret it for a second.
They're pretty accurate within reason, thinner and much easier to use than
the Rockler bulky resin models and they measurably speed up assembly time on
any square construction project I happen to be building.
Hell, a case of beer, at least up here in the great white north costs more
than these clamps from Lee Valley. So, instead of literally peeing some my
money down the drain, I have a useful tool that I expect to remain useful
into the foreseeable future. Can't complain about that.

You could but having them hold up in use and stay square is more
problematical. You'd be forever knocking the cross-grain leg off for
example and wood changes its dimensions with humidity.

Only one and a half times the cost--the Rocklers are ten bucks a pop,
the Veritas are 30 bucks a _pair_.

'Pends on how their made and of what. May not remain square to the mil,
but certainly can be done "good enough" for most any general woodworking.
I've got a few chunks of 3x3 angle also about that long that are close
enough for anything that doesn't have to be absolutely perfect. If that
doesn't suit, the welding angles are good as a reference and a little
shim makes them snug. Cheap 'n cheery... :)

I was thinking I should have noted the angle I use is Al which is
smoother surface than structural iron and generally more precise as well
as the weight advantage. As here, the ironmonger has scraps for
cheap...really short little cutoffs for stuff like this may be just
handouts out of the trash bin...

Corian would be a possibility.
Baltic Birch might be another--with domestic Douglas Fir plywood one
would have trouble getting a decent degree of smoothness on the edges.

I made a 90-degree block and keep with my clamps. It has been handy a
few times. Wax the block to repel glue. Metal 90-degree brackets
work well too. I think $10 is a little steep for a 90-degree corner
brace.

As previously noted, that's for a *pair*, compared to price *each* at Rockler
-- and they're an order of magnitude closer to dead-on square.

It's not as bad as that. Look again: $29.50 for two vs. $9.99 for one.
Also, there are other sources for this item that are less expensive than LV.
Finally, notice the advertised tolerance on these. Notice also that Rockler
does not specify the tolerance on theirs -- with good reason, I might add (see
my other post in this thread for details).
