Okay here is an update, thanks for all of you who replied with some help. This is my first refinishing job and its on a $100 guitar, I got it at a pawn shop over 15 years ago. Literally my first real 6 string I just didnt get it at the five-and-dime. Lol. So needless to say this does not have to be a perfect finish and I will also note I have been planning from the on set of this project to a fairly heavy black burst finish around the edges of the body, enough that between the burst and the pot knob this shouldnt be an issue at the end of the day.
So with that said 2 days ago I attempted a repair on a plan I developed with the help on here. I masked off the area and glued in a piece of my maple veneer. I really forced it in deep to seat all the way in.
After about an hour of drying I used a razor blade to start trimming it down to the body
I removed the masking tape and trimmed with the razor down flush and I am very pleased with how the repair came out.
My attempt to stain it to blend was moderately successful. Thanks for the heads up Woodenspoke I was unaware that Titebond II would not stain, I grabbed it because it was the suggested glue in the veneer tutorial on projectguitar.com
As for Drak's request to see the body cavity on the reverse side here you go:
The wood is fairly thick at the pot hole before the veneer was applied, i'd say around 3/16", the veneer is thin obviously only around .040" thick. The crack is ONLY through the veneer the body wood is still sound.
The last thing I will show is my "burst" finish templates. I do not know how exactly how deep of a burst I will need for the overspray to cover so I have cut a series of templates for the body in 1/4" increments, start large and work up if needed. So there is a Plan 'B' in the works for this.
So I guess to avoid this on my next project from the feedback would be:
#1) Do not use Titebond II
#2) Let the veneer dry for 48 hours prior to trimming the veneer? Or should I go longer?
Thanks for all the help here guys on this, much appreciated from someone brand new to this Hobby.
