So that's what halfway between maple and rosewood sounds like

Postby John Cross » Thu Nov 02, 2017 12:02 am

I haven't posted in a long time. I just finished this parlor guitar for my wife. She picked the woods before she started taking guitar lessons a couple years ago. It has a number of interesting things going on so thought it was worth posting. Specs are:

Top Alaskan yellow cedar
Sides East indian rosewood
Back Spalted flame maple
Binding and armrest Mahogany
Neck Mahogany
Fingerboard and bridge East indian rosewood
Inlays Abalone
Finish Padded on liberon oil finish on the body and tru-oil on the neck (I ran out of liberon)
Shape approximate copy of an unplayable garage sale parlor guitar I was given years ago - similar-ish to a Martin ooo

In addition to the odd wood combination and the armrest, it has a carbon fiber flying buttress supporting the neck block and a fully adjustable neck. The neck adjusts via a stove bolt that goes through the strap pin on the neck heel. If you dindn't know, you would just assume it is a regular strap button. I drilled it out so the bolt would go through it instead of using the screw that comes with it. The bolt threads into a t-nut in the neck block (no effort was made to hide it inside - I never look in there). The fingerboard floats over the body and has carbon fiber rods epoxied to the bottom to stiffen it. This is the first one I've done this way and am already totally sold on it. Within a minute of bringing it up to pitch for the first time, I had the action dialed in better than most of my electric guitars. It sounds good too which is an added bonus.

I took lots of pictures during construction (400+) and kept track of my time. 41 hours in total (less than I expected) spread out over a full year of tinkering (I only worked 42 days on it). If anyone is interested in any parts of construction, I'd be happy to post more.

Enough rambling. Onto pictures.

Lovely job! I do love a 12 fret parlor guitar. I wonder about the details of the neck joint - is it fastened at the upper part of the joint? Did you recess the heel into a mortise to get the seamless look?

Looks great. You don't see a lot of back and sides using different woods so I wasn't sure what to expect when I got down to the pictures. They came together nicely.

I've never kept track of my time "tinkering" but my estimates are WAY over 41 mins. Perhaps I should keep track next time I start one. Maybe I'll surprise myself.

That does look really nice John. I always knew you worked a lot faster than I do, but 41 hours is really amazing. On my latest guitar I'm sure I spent 41 hours looking for stuff I had just put down on my workbench a minute before. Guess I should clean up my shop.

With all of the 'different' stuff on it, I'd hesitate to attribute the sound to any one thing. It's a nice looking instrument, though, and it's good that it sounds nice. I have a student who's just finishing a 14-fret 00 with walnut sides, maple back, and a white pine top. He's used the pine before, but not on that size box.

Thanks for the kind words so far. The neck is just held on by the one bolt. It should be more than strong enough to hold everything together. It will be a bit loose and floppy when changing strings but no big deal as I will expect that. The only other hardware in the neck joint is two small round head wood screws which act as pivot points. It feels rock solid when strung up. The neck extends into a pocket in the body maybe 1/4 inch. From the playing position, it looks seamless. I took my time trying to get it perfect so even if you look from the head stock down the neck, the biggest gap can barely fit a piece of paper. I used to spend just as much time flossing the neck joint as making the pocket on this one so I don't think it takes all that much more time.

Saying it sounds halfway between maple and rosewood was a bit of a (lame) joke on my part. I couldn't attribute the sound to that feature alone for sure. it definitely doesn't hurt the sound though.

Very nice looking guitar. Please post construction pics of the neck joint.
Maybe I can't fix it, but I can fix it so no one can fix it

I've used a similar neck joint a few times. One minor 'improvement' is a setscrew in the pocket at the bottom as a stop for the neck angle. If there's space back there it's easy to pull the neck back and have the strings bottom out; a setscrew obviates that issue.

Here is how I did the adjustable neck.



Here is a picture of the hardware I used. A standard strap button drilled out for a 3/16 hole, a 2 ½ inch 3/16 stove bolt, a 3/16 t-nut, and two round head wood screws. total weight is quite small (19 grams)

First thing to do was drill the neck. I marked where I wanted the strap button.



Then I use the strap button to pick the best drill bit.

Drill a countersink the button will fit into. Followed by a picture of the button
