After several weeks of doing fiddly stuff and not make ANY progress on the guitar I finally got around to bending sides. This was very exciting because now it would actually start looking like a guitar. When people have asked to see what I'm working on and I show show them flat un-cut or bent wood they seem disapointed. If I say, "yes, but here are the braces I've made--no, you don't see them because they go on the inside" they doubt my sanity even more so.
Bending is also somewhat nerve wracking. Taking an expensive (about $40 a slat)piece of FLAT wood and forcing it into a couple of gentle curves and a couple of very extreme curves is daunting. If not done right, Snap Crackle, Pop and swearing will result. I practiced on some "doorskin" paneling before I used the mango.
This is what happens if you go too fast. This is the lower front of the guitar. It has a bend that's about 140 degrees. Good thing it was the doorskin. I have lots of it!
Fortunately, there was very little drama.
I got to use the class's Fox Side Bender. It's a jig that holds the wood and pipe bending forms I made earlier and heats the wood using light bulbs while you clamp in various directions.
The wood gets spritzed lightly with water and wrapped in parchment or aluminum foil (to hold the steam in) and placed between 2 steel slats. Then, it's placed in the machine and the giant clamp on top gets cranked down. Turn the lights on and let the heat and water work their magic.
Little by little you tighten the cauls into place. The big crank is first. It's the waist of the guitar, and it has a gentle curve. Next is the rear or lower bout of the guitar.
The bass side was fairly easy as it was 3 gentle curves and it bent in about 20 minutes. The treble side was the tricky one. You can see the light leaking out between the the wood/steel sandwich and the side of the bender. The side will eventually bend to the shape of the mold thanks to the springs on the caul (big wood thing on the outside) and the heat. This made me nervous! I still have to do another outside bend where it will join the neck. That gets done on the pipe bender next week.
After the bending and the cooling. the sides get clamped into the big mold so they will retain their shape and its a nice safe way to store them.
I also went ahead and pre-bent the ebony binding pieces. One less thing to worry about down the road.
Now I have to get back to the rosette, which is proving to be a major headache.
I keep wandering back out to the garage to see if there is anything else to do. I am not good at the waiting-thing.
Maybe this is good for me?
Like all Blogs on the Interwebs, this is just a collection of stuff that I'm interested in. Bla Bla Bla....

I was surprised at how fast it went.
I was some pictures from Mexico and guitars that looked carved more then carefully bent.
Hi Ronn
Thanks for your comment on my blog
Of course I had to visit yours to.
Some show you have here....
I especially like you're guitar building posts, always nice to see someone else finding his way to the perfect guitar....
A tip for your next guitar mold. Make the first layer perfect. Use a copying bit on a router to make an exact copy and glue them together.
Need some minor sanding when all layers are together.
I will check on your blog soon.
Regards form the netherlands.

Wim,
Thanks! The class I am taking wanted us to glue, then cut. I brought up the router idea to no avail.
