Engelmann/Honduran Mahogany Dreadnought build
Posted: Sun Jun 16, 2013 3:29 pm
I'm just getting started on my fourth guitar. The first was totally from a kit from StewMac. It came out too tight for me. I'm sneaking in from time to time and shaving the X braces to try loosening it up. The second was for my daughter and came from KMG. The neck got all wonky as far as mating with the top because of a misunderstanding on profiling the top. I will scrap that body some time and keep the neck. It has special meaning to me. The third was for my son, and it really sounds nice. Everything came from a Martin kit that a married couple sold to me so cheaply that it wasn't funny. They had no time to build a guitar. I got the top from Tony Costa, a Bearclaw Lutz Spruce that turned out nicely.
This one is Honduran Mahogany that I got from RC Tonewoods sometime back, and an Engelmann top just in from LMI. I'm using a number of pre-shaped parts on this, but otherwise it's not kit built per se. I got a tower binding machine from John Parchem, and am so ready to try it out. Much appreciated, John. And John Hall provided me with a bending machine for my first stab at bending sides.
Here's one of the sides as it sits on the plan sheet from StewMac. It looks like it's out of whack with the plan because I moved it to the left and forgot to put it back. It fits!

And here's the obligatory shot of one of the sides in the bender. I don't think I've seen a build yet without that shot. Oh, let me tell you. Bending sides in one of these is a snap. I'll leave that word in :). I had the easiest time. Previously, I bought 4 pieces of sides from LMI to practice bending with. I used water on the first 3, two with paper around them, one without. All 3 came out pretty rippled and wavy. After consultation with people smarter than I, I did the fourth one dry with no paper, and lower temp. It came out with a bit of waviness, but nothing that sanding won't cure. And the 2 Honduran Hog sides were pretty good.

Here are the 2 sides in one of my forms. This form was from KMG. The 2nd one, I think came from John Hall. It's modified to help with clamping, but is liable to become un-modified because it's a bear to open. There are hinges on either end with screws, so you have to unscrew one end once the body's ready to come out.


Here's a couple of pictures of the back set - not yet joined or profiled.


And finally the top. I'm having a time getting a picture that shows how white this top is. there's a ton of silking as well. Since the top is .015" thick, it needs to be thinned down pretty good. I'm going to try my hand at using a plane for this after I practice on some old pine. I'll start out sanding a little to see if the reverse side of this top looks better. It's giving a hint that it might be pretty good itself.

There is just enough waviness in the sides that although I could sand it out, I'm going to try to use braces on the sides to straighten them. I'll test this out with some of the ends that will be cut off. If that doesn't do it, I'm considering SuperSoft II or something like that to maybe work them into shape. There's no time constraint on this build, so I can wait if I have to.
I've learned a number of things on the first 3 builds.
1. Do not rush. It's easy to get excited about a part being ready, but giving in to it can be dangerous.
2. Don't say "oh, I'll fix that when it's time to finish". Fix it now. You either won't remember or it will be too late.
3. Prepare the body for a successful finish. Even on the 3rd one, I thought I'd done a good prep job. But closer inspection showed me how wrong I could be.
4. Treat the top, back, sides, neck, fretboard, etc., with care. I'd do something on the neck, then set it over on the other side of the table and then knock it into something else. I'd put the top on top of a chest, and knock it sideways into somethine else. Turn over the body, get grit or something into the top and there'd be a gash down on the lower bout. Don't even get me talking about the finishing process. Somogyi keeps a paper cover on his tops except when he absolutely has to take the cover off, or when it's all done.
My new year's resolution in June is to avoid all those bad practices and make this thing something to be happy with and proud of.
Thanks for looking,
Bob
