Help to get the cheeks flush to the body
Re: Help to get the cheeks flush to the body
The references are to what you are likely to have/find nothing about making if so -- and there is the also note that Stem Mac might send a neck with no angle machined at all. So actually your starting point should have been to determine the check angle on the neck you have there. The idea is to make the neck cheeks and the fingerboard extension have complimentary angles forming a straight line.

Re: Help to get the cheeks flush to the body
As an example Mark, I recently had a neck that had an 88* angle (cheek and FB surface) that required a 92* complimentary angle on the body to keep it straight (88 + 92 = 180 [straight line]). The complimentary angle needs to be machined in at the start (the MM does a great job of that) or you end up having to do more tweaking/fitting to get it right.ken cierp wrote:The references are to what you are likely to have/find nothing about making if so -- and there is the also note that Stem Mac might send a neck with no angle machined at all.

If you didn't check that to start that is probably part of what you are experiencing now.

Tim....that's exactly what I didn't do. I needed to check the neck angle before I started anything andTim Benware wrote:As an example Mark, I recently had a neck that had an 88* angle (cheek and FB surface) that required a 92* complimentary angle on the body to keep it straight (88 + 92 = 180 [straight line]).

then figure out what the complimentary angle needed to be. Actually, now that I think of it, I was trying
to do it the other way around (body angle then neck angle). I'm not sure how I came to that idea.
Anyway, It's a good mistake to learn from as I move forward in building future guitars.
Thanks!

I agree with Mike re-read all the stuff shown and explained here
http://kennethmichaelguitars.com/neckangle.html
Don't do anything more until you understand where the processes are going to take you. Ask questions if need be to get the concepts clear -- all the procedures require action related to cause and effect.
Show us pictures of the joint with the neck bolted in place with the simulator also securely clamped. This is not about specific angles but totally about making the fingerboard plane and the sound board extension area form a straight line
Here's a couple pics with the simulator. It's close but the cheeks still aren't
flush to the body....

Re: Help to get the cheeks flush to the body
Pretty good -- you may need to do just a tad of adjusting -- do nothing for now. Since we don't know your exact angles on this build you need to lay a straight edge on the FB plane and sound board -- full length nut to bridge location. Make sure the neck is bolted tight and the straight edge in touching. Take some pictures, we are looking for the gap at the saddle

This is the only straight edge I have and it's 24"

"Take some pictures, we are looking for the gap at the saddle"
Slide the level more toward the end block so you can take a look at the measurement you are looking for. I can tell there is more work to do, you're tipped too far back from the sound board. The gap at the saddle should be about 1/16" +/-
