A homemade reamer for the end pin

Post by MaineGeezer »

When one has a machine shop in the basement, all sorts of things are possible. I made a reamer to match the rather arbitrary taper of the end pin I made. It's a pretty poor reamer, but it was good enough for one hole. I used the same lathe setup as I did when making the pin so the tapers (in theory) match.

Awesome. It is fun when you can make your own tooling.

Kerfing, side braces, and sound port reinforcement installed

Post by MaineGeezer »

I've got the kerfing glued on. It's not as even as I would like, but I guess it will do. I trust that when I sand the radius it will all even out.

The side braces are installed. Carter believes in substantial side braces -- he's seen guitars with rippled sides, and wants to prevent that.

I also added some black veneer in one spot as reinforcement for a possible sound port. I'm still debating whether or not I'll cut one, but with the reinforcement I have the option.

Good job on the kerfing, and yes, it will be beautifully even when you radius it for the last time. I also used more struts than some people do to stiffen the sides, especially since my top was thin.

Would like an opinion.....

Post by MaineGeezer »

As can be seen in a previous posting in this string, I've bound the fingerboard with ivoroid. download/file.php?id=6702&t=1
Now I'm thinking I would prefer wood binding of some sort. How weird do you think it would look to use, say, curly maple binding on the guitar with ivoroid binding on the fingerboard?
Or should I stick to my original plan to use ivoroid and save the wood binding for the next guitar?

I just did a setup on a Larivee that had maple binding on the body with ivoroid on the fret board. It looked ok to me. I did not even notice the difference until the owner pointed it out to me.

I would have done both in the same binding myself. But that is just my preference.

But as I said I did not notice it.

I guess I now I can't deny responsibility.

Ready (I hope) to glue top and back to the sides

Post by MaineGeezer »

Here's the sides in the mold, with top and back ready to glue on. The kerfing and sides are notched to clear the braces, the sides have been sanded to the proper radius. The top and back touch the sides all the way around.

I also made a couple of cam clamps, shown on the right. The thing is, I need to make about 20 or 30 more of them, which isn't going to happen. I'll borrow Carter's.

Back (finally!) being glued to sides

Post by MaineGeezer »

Here's a photo of the back being glued to the sides. One can never have enough clamps....

Hi Steve,

Curly maple would look fantastic and it wouldn't look bad at all with the ivoroid bound fingerboard. My Masterworks MD95 is bound in curly maple and I used curly maple on my OM build. It's simply gorgeous when finished, especially when you use maple with a tight curl; the chatoyancy increases the visual interest of the guitar and it adds class.

IMHO, when you put this much work into something, it's more than a musical instrument; it's a piece of art that reflects you. It deserves the best materials. There is no hard rule about matching the binding around the entire guitar. I would go for the curly maple.
