new classical with spectrum

Post by Jim watts » Mon Mar 28, 2022 1:30 pm

Just complete this.
Honduran Rosewood and spruce 7 fan open harmonic bar classical
A v-joint on the head stock which was something I've been working on
I'm pretty happy with it as it sounds and plays pretty nice.
I was pleased that I was able to get the spectrum into the range I was shooting for.

Very nice guitar! I really like the guitars I made pitched around 190 Hz for the top. I love how the headstock joint worked out.

That's a nice tidy looking guitar Jim. Well done with that V headstock joint.

Great work Jim. Looks fantastic. Do you have any photos of the V-joint of the headstock in progress? The end result looks great.

Hi Mark, I have a couple of photos.
The things that helped me most were a wide super sharp chisel, 25mm was my widest, a marking template that can very accurately mark the joint all around the neck and a highly repeatable clamping method for test fitting and final glue up.
The photo below is my marking template, this allows me to mark the top and bottom of the neck using the same reference side of the neck blank. I put a 10 degree angle on the neck shaft side so I align the template to a 10 degree line scribed on the side of neck shaft.
The pin in the picture is removable so it comes out for marking the neck shaft. The same template marks the peghead side. The pin is used to control the template depth on the peghead side. I cut the peghead slightly deep and dropped the peghead down onto the shaft by planing the end of the peghead on a shooting board. I hope that all makes sense! It takes some finessing after that, but the better your layout the less finessing required.

The next photo is my clamping arrangement. the peghead is placed up against the bottom side of the upper block, then the shaft is pushed into it with my end vise. It's a little cobbled together, ok a lot cobbled together but it worked very well. Pat Foster gave me the idea for this, I'm not sure if he's a member here or not.
