Hi everyone!
A new/old member here. Been looking around but never posted before as never needed any help concerning my custom baladeer mod 1612.

I´ve notice recently that the neck is getting a bow and need strighting up a little. But after finding the right wrench for the kaman bar and finding impolsible to turn it, not even a tiny bit. Sems solid as a rock.
How could I managed to work on it?? I dont want to force it and break it.

Any help will be greatly appreciatted

Thanks
Javier

Hello scarecrow
Have you tried turning the wrench both ways, and how about taking the tension off the strings and then see if it will move for you...hope this helps.

Try spraying a bit of Liquid Wrench or similar product around the truss rod nut and set the guitar neck down to let it penetrate. It may need a couple hours and/or re-application, then try GENTLY turning both directions and apply again if needed. Don't force it!

Hi,
The truss rod doesnt move in any direction. I´ll spray it with sone lubricant and see if it works.
Whoever design the kaman bar, wasnt a guitarrist...

thanks for the help.I´ll keep you posted

I heard that Charlie was a decent player. Sounds like the nut is stuck. That could happen with any truss rod.

I was thinking the inventer was Charlie, but maybe it was Bill's name on the patent. (In response to scarecrow's comment that the designer of the Kaman bar wasn't a guitarist).

My guitar shop has a Kaman bar neck that is cut in half as a display model. Those things are seriously well built. I suspect that the bar will take quite of bit of torque without damage to the bar itself. My worthless free advice is a little Liquid Wrench, a little tapping, a lot of patience, and then a little nerve.

What would Red Green do? If that doesn't work get a bigger hammer.

It's very unlikely that the K-bar nut will be locked both clockwise and counter-clockwise. Just a thought, make sure you're trying to adjust the neck rod, and not either of the 2 larger bolts that sit immediately below it. These bolt the neck to the bowl, and you don't really want to mess with them. What size socket are you using?

HI,
No disrespect here to Mr Kaman, but putting the trus rod right "there" is not the easiest of possibilities...

After checking with a mirror I could only find one bolt. well really the neck bolt is way back so no confusion here on my part.
Secondly, regarding the manual I still have, I must be using an 1/4 hex, that actually dont even fit in the hole (...), so I kept trying untill I found the right wrench (3/16.) what brings us to the very begginign of my first post.
Ive just sprayed with lubricant and will wait a few hours.
Will keep you posted.

Thanks again.

Javier

Yes 3/16 is correct. Std tool is approx 41/2"x1"
Tonight I adjusted the neck on my 1619 Custom Legend that I got today.
It is a bit awkward but I loosened the middle strings a bit and that made it easier to get the allen wrench into the capscrew,long shank first.
That puts the short shank about the middle of the sound hole.
There was no way I could turn it just holding the short shank.
I got a 1/4" hollow tube spanner about 4" long and put it over the short shank to increase the leverage.
Mine was certainly tight and took a little effort to get it to move.
I initially was able to get it to back off a few degrees and once it did move I moved it forward and back a little bit to free it.
It was still firm and I only moved it probably 20-25 degrees in total.
The adjustment is obviously very sensitive because that was enough to give it the correct clearance.

I have seen two K-bar necks where top glue had dribbled down and glued the brass adjusting nut in position. A certain 1858 that's now in the Great White North had that problem and the prior owner stripped the brass head out. Try to spot it with a miroor, and then chip the glue off with a dental pick or screwdriver. If you just crank on it I will then get to tell you how to put a new hex head on the nut.

Hi,
I managed to twist the bar using the trick pointed by AussieJames and used a tube and some patience..

Im in the process of adjusting the neck and see how it develops.

Thanks to everyone for your support
