Hard To Use

Very hard to get the brace in place and turn it to expand while not moving it out of place. It needs a thumb wheel that you can turn while holding the entire jack in place. It works, but be prepared to spend some time getting it into position.

I'm sorry to say these don't work well for me. The older models were better, especially the ones with wooden ends with cork padding. Those were the best. Even the ones with the square black plastic ends were better than the current model. These new ones are too tall for many acoustics and the round shape of the ends makes it difficult to get the jack to stay in place while tightening. This is further complicated by the extremely slippery white plastic (nylon?) ends. Guys, please bring back the original design.

Nice idea, but a tad lightweight

They do the job, but I think the turnbuckle should be sturdier, and a little shorter.

A bit too big for my job

I got one of these for an ES 175 style kit that I'm building..the guitar had no bracing on the top plate so this was for clamping the braces at the rear. The jack was a bit too long for the job - the Scissor Jack would have been perfect. I'm sure I'll find a use for it though!

Brace Repair Jack

I used these jacks on a old '69 Eko Ranger, with complete success. These guitars were never the best, but the wood was carefully selected for the body to get that special tone.

The solution

Exactly what I need to glue the broken braces off this guitar. Easy to place and easy to fix for this gluing job. Easy to remove and no mark left!!! Perfect.

Hard to beat for the price

Like others have said, be aware that this is only going to work on full size and jumbo acoustic bodies or acoustic basses. The StewMac scissor jack is what you really need for the type of jobs where you would use this little tool. But for the price this one is hard to beat. I also appreciate that the plastic ends must have teflon in them cause dried glue that gets on them doesnt stick. Just pops right off.

Not without Issues

Bit big for a lot of acoustics - would have more applications if 10mm smaller. Fiddly as well. On the other hand, can't think of another tool that does what this can

good idea, too big for size 5

This would have been just fine for fullsize, too big for Terz. I wound up using a metal ruler cut to size, used as a spring against the brace...worked perfectly.
