Monkeypod Dread

Post by whitespruce » Fri Mar 20, 2009 11:07 pm

Well, I am taking a brief side trip and building a guitar out of my new monkeypod. Mainly to see how it works up before I get in the midst of selling the wood. This monkeypod is a bit lower density than earlier monkeypod I have bought, more on the mahogany-like density. Talked to my supplier and he said it really varies a lot from tree to tree, even from two trees growing next to each other. This shipment was all from one tree, so I'm just checking it out.

This is going to be a fast build, because I am using parts that were already started. I have a top already braced that was going to go on a mango dred, but I am diverting it to this build. And I have a neck all ready except for the fingerboard and carving, but I have a fingerboard already slotted and tapered. I also have a neck block and tail block ready.

So I have resawed a few sets and today I picked out the parts. Here is the back and sides along with the neck and neck block.
Image
One thing I need to mention is that I was using this to play around with camera settings, so the wood looks a different color in every photo, and most of these make good "before" photos ;)

Here are the sides after profiling.

Ready to bend.

Here is the first side in the bender.
Image
Nothing out of the ordinary here, just my usual. I did make a new caul for the lower bout. This is to cut down on the cross ripples. Very hard to bend the lower density woods that have interlocked grain without getting ripples. Mahogany and the like. These bent very easy. I set the temp to 300 degrees and they started to "wilt" within a minute or so after turning on the heat.

Here they are after bending.
Image
They bent flawlessly at a thickness of between .090 and .095". There is a bit of springback in the upper bout bend, but I didn't bother to give them a second heating. It does bend to shape with almost no effort.

So I just reclamped them to the bending form until I am ready to assemble.
Image

I glued up the back just using the tape together method that I usually do.
Image
This is one of those photos where the white balance was set wrong. Thought I had it right, but it switched on me because I did not save the setting correctly.

Then I ran it through the sander and cut out the shape a bit oversize.
Image
And on this one, I finally got the white balance correct. This is what all of the wood in the above photos should look like. But a bit dark on the right and probably did not have the camera braced well. Doing things a bit hurridly.

More over the weekend.

That is great timber, Grant. I'm gonna get some of that stuff when and if the £ is stronger against the $.

With regards to workability, what can you compare this wood to?

Grant,

The wood looks a little like mahogany--in any of the photos. You seem to be saying it bends like mahogany...? It looks like there is no springback in the lower bout, although you might have it secured where I can't see it.

What do you use for your heat source in the side bender?

This is a good idea Grant, only way to get a real feel for the wood.
You say this has more of a mahogany density, and I was thinking that it looks a lot like some mahoganies as well.
Going to be fun to see how this compares!

Go Grant! Should be very pretty when finished - like aged Mahogany.

Are you having this one sprayed with "cat poly"? Your first guitar finished with that stuff looks great (how is it holding up?)

Cool!

I got a better idea for my bender, (Additional forms and screw downs instead of springs),

and we see that Erik's teachin' is already takin' hold, even among the older dawgs!

;) :shock: :lol:

Jim, there is absolutely no springback in the lower bout, but some in the upper (notice in the photo of the sides clamped back on the form that the tail end of the lower bout is not clamped and it is tight). I think the whole reason is that the lower bout was bent first and had a good 10 to 15 minutes of heat after it was bent. The upper bout only had about 5 minutes of heat after it was bent. I should have given it another heating cycle, but I was in a hurry.

I use a heating blanket with Tom Durr's system.

And, yes, this does somewhat resemble mahogany in appearance, but it has way more pronounced color striping and a much different and darker color under finish. You wil see that when I have the epoxy fill coat on.

And I do plan to have this sprayed with the catylized finish. The first guitar I had that done on seems bomb proof.

Thanks for looking and the questions and comments :D
