Looks like you might have leaned asymmetrically during sanding using a sanding beam, not a dish. I use a beam and that is something I am constantly aware of and checking for during the shaping of the rims. The heel and neck blocks do not respond as quickly as the side next to them.

You can do the same thing, using a dish. I avoid it by moving around the box every few turns of the dish so that I'm not applying too much pressure in any one area.

I elected to glue the the top on last night. I’ve been putting it off for forever but it turned out alright.

OMG you are absolutely right! My lower bout is all out of whack; the sides are actually higher than the block - with a noticeable cant to one side. I seem to have inadverntently reinvented the Manzer wedge! I'll be going at it with a block plane today and "eyeballing" it more instead of letting the jig do all the work.

It's times like this that I'm tempted to sign up for one of John's classes. I have been socializing with musicians online (sort of as an offshoot of doing "virtual" open mics) and might even have some clients if I ever figure out what I'm doing!

I've done the same thing. If you want quick accuracy and have a caliper, just measure the inside, from the inside back to the top edge, symmetrically around both sides, about every inch, and mark the height. You can connect the lines, then you can quickly plane the wood to the line.

Ok. Hurdle surmounted. The box is now closed. On to worrying about how to rout for binding, but I have a plan and will be making another jig.

...and three months later I’ve routed for the binding. I had to figure out how to do it and built this jig based on plans from Chris Ensor, but it looks like it may have come out of the Larrivee school of lutherie. I e seen Martin use something similar in their factory. It seems a lot more compact and less involved than the LMI tower and cradle assembly:

I’m also in the process of doing something I’ll probably never do again: a non wedge-shaped end graft. Next time I’m going back to basics.

Your neck looks great. Love the jig.

Thx, Diane.

I don’t think I’m going to do another laminated neck. They’re heavy and can twist. My first built that I completed in December 2013 has one and it’s in need of a reset.

The jig works great in how everything lines up but I need a better bit. I need to get a new router too. I’m finally beginning to realize how bad many Harbor Freight tools are!

Interesting comment about laminated necks - - - weight and tendency to twist. I'd be very pleased to see more comments on such necks, as I've made three with the idea in mind that any twisting tendency of a solid neck blank is countered by the forces available to a laminated neck to oppose each other and tend to cancel out. But I'm new to this stuff.

Thanks!
