I mistakenly call the pocket truss wrenches that you link to box wrenches.
The wrench that I have came with my prestige. It is 7mm with a wall thickness of 0.05" (1.27mm). The space between the nut and the wood is 0.04" as already stated.
I've also tried a 7mm nut driver, which has thicker walls. A taylor truss rod wrench will probably not fit, but I am just guessing that taylor has imperial instead of metric dimensions.
I am not for routing wood, I am for grinding my "box wrench" or a harbor freight nut driver.
So in summary, no tool (that I have found) has a thin enough wall to fit. I am not freaking out on this. Taking my time and going slow, like I do with all repairs....
A box wrench won't do it. Do you have something similar to this?
I believe a Taylor truss rod wrench will also fit. I have never had to route away wood to remove
a truss rod nut before, and I don't think you need to here. Even if it is a little tight on that end, the right tool will be able to slip in there and lift the rod up slightly allowing you to remove the nut safely.
If you don't have a wrench like that you could hit the local guitar store and use theirs, though you should find one for each of your guitars.
Really you are making this problem harder than it is, take a deep breath, relax, and find that wrench. After you get the nut off its easy to clean up in there and get things fitted right, but don't make things worse on yourself by routing out the channel.
You are correct sir. I do have an IBZ (an old 440RG) that uses an 8mm TRW though....back to this neck...I know that a 5/16 TRW does not fit. I have a set of nut drivers, the 7mm seems most likely to fit, but the wall is too thick by 0.01". Instead of hammering it in, I'd prefer to shave the metal some....
Unfortunately, I don't have a grinder handy, so it'll have to wait until next month and taking off 0.25mm with sand paper will take some time...
Yup, I would have assumed you were using the correct Ibanez 7mm TRW.
But, I have had around 10 Ibanez over the years that you could not get a correct wrench on without either force, or routing the channel deeper. There are plenty out there.
