Any body ever try these Jet 90 Degree clamps

[lcm1947]

I was looking for some type of clamp or whatever to build some cabinets and I ran across these at Lowes. Anybody have any experience with them? They sure look like the ideal thing to aid in the construction of cabinets. I always have problems trying to hold everything together since I seem to have less hands then the parts I'm working with. I tried one of them at the store and it held and pressed together two 24x24 sheets of ply real well. They sure seem like a winner and only like $7.97 apiece.

very good, well made clamps. I got mine for $10 each when HD was clearing out. normally $25

these are not bad when you can find them, better than the ones you show but not as nice as the Besseys

What makes them better?
solid, beefy construction the parts don't bend, they jaws don't wiggle as you close them, the Bessey's have single screw tightening and self adjusting jaws, the Sears have quick release so you don't have to screw the jaws so far. and the jaws protect the workpieces.

Thanks Loring and thanks for all the options. Really really helpful you taking the time to locate all those for me. I did see the Jet ones at Lowes but $22.00 each? Ouch! How many would you need, like 8 of them to properly set up the main compartment of the cabinet?

You can probably get by with one or two...

with 2,
if doing frames, you can do two opposite corners, then do the two final corners to complete the frame.

with 2, if trying to do a cabinet, then you can do one corner with two clamps, one corner at a time.
But, I think you might consider just using the square angles brackets with clamps like these:

personally I don't buy them, I make them from butt-jointed 2x2 about 8" long for a lot less $$$, just gotta make them good and square.

Thanks Loring. Boy 2's a lot better then 8. That I can afford and I guess there's no reason why I have to do the whole thing at one time. Good thinking. Hey, neat brackets you made. I'll certainly have to try making some of those. Great idea!

if you make your own, there's a couple of Heavy duty 3" countersunk screws holding the butt joint together
and don't forget to break the outside corner and relieve the inside corner to allow glue squeezeout/corner relief.

I was going to ask about those inside corners, so now I don't have to! But, what do you mean by "break the outside corners?" Break??

Chamfer. The outside 90-degree corner of the jig, when used on the inside of a joint, will be exposed to glue squeeze out and also the corners due to glue, splintering and other swelling aren't perfectly square right up to the corner. About 3/8" chamfer is what I used.

The 1/4" hole drilled centered on the inside corner does the same thing when you use the jig on the outside of a joint.

Another corner clamping bracket

Along the lines of Loring's pics... Would the plywood be more stable than solid 2x's? I haven't tried either yet, so can't comment.

I have these. They work OK, but as Loring said, they're not great..

Thanks again Loring. Good details I needed to know as I do plan on making some. I went to HF today by the way looking for those Bessey knock-off's but couldn't find them.

Has anybody tried the Bessey clones from Harbor Freight?

I'm tempted. I want to make a bunch of drawers and I'm seeing that using brads with an air nailer isn't doing the trick. I seem to be knocking some joints out of square holding them by hand as I nail. Clamping would help a lot.
