I just discovered roasted maple thanks to a mention in Fine Woodworking. Does anyone have information on the process of roasting maple? I read that the wood is kiln dried to 4% then heated at 360 degrees F for four hours. The carmelization goes through the whole board. Is this something I can do in a regular oven? Has anyone ever tried this?

From a brief Google search, no, you probably can NOT do this at home. The high temp process includes establishing a vacumn in the oven – which would not be easy at home.

It appears that this process is usually performed in order to improve the dimensional stability of the wood for such applications as guitar necks. But is sure is pretty!

I tried it once, but the taters and carrots stained the wood.

Basically, at the end of the kiln drying process they crank the heat up and bake it for 2 days. It was discovered while trying to find a stablized wood for a sauna door. It makes the wood rot and bug resistent and it does not move. It aso turns it chocolate in color which I hear is becoming popular with the housewives.

Gibson has started using roasted maple for fretboards, after getting into hot-water with improperly imported east-Indian rosewood. I don’t really like the look for fretboards, but that’s just me.

I never heard that Gibson was actually convicted, just accused. There is a big difference.

The settlement of the case, as I understand it.

Michael: A good summary of the final agreement is here:
http://dotearth.blogs.nytimes.com/2012/08/10/a-closer-look-at-gibson-guitars-legal-troubles/?_r=0

Basically, Gibson paid a fairly big fine, lost a large shipment of ebony, got its rosewood back, and agreed to tighten up it’s import practices in exchange for having the charges dropped.

After a similar situation as yours I did some google work and found some information on roasting: wood is brought to 4% water content then heat at 360F for 4 hours. So….I have an oven and thats an invitation to try this.

BEFORE:

1. Material is 1-1/8 thick maple with great figure.
2. Heated oven , convection for the culinary folk here, to 360 F
3. Baked for 4 hours…definitely want the windows open and the fan on!
4. Final color is awesome!

At no time did I feel the wood was in danger of combusting, the smoke was minimal. It never set of the smoke alarm in my kitchen. Wife did want to know what I was cooking when she came home!

Leaves a great color throughout and better yet SMELLS really good!

After:

Wood high temperature tooling

A few years ago we needed to make some tooling for curing composite parts at 350 degrees for 16 hours. Normally such tooling is made from steel or composite cast from a inverse tool made from a low temperature material. We didn’t have time or material to go through either process. So we made the tooling out of wood. Even though Machineries Handbook says that pine can go to 800 degrees and oak 900 degrees, our safety people said we needed testing to demonstrate that the wood wouldn’t burst into flame. We ran pine at 600 degrees for 3 hours and yes it smells and gets a beautiful color. Since we couldn’t use glue all the parts were assembled with dowels. All the wood was precooked to drive out moisture and to solidify the resin. To mould the part we vacuum bagged the tool and then put a vacuum bag over the layed up part. The part came out acceptable with only surface touch up where it picked up the wood grain through the first bag.

I wish I had known that this created desirable characteristics as I would have started my own “bakery” and retired sooner!

OldWoody,
Did you take the wood down to 4% in the oven first?

Nomad62, I bet after 4 hours at 360 degrees the gravy wasn’t fit to eat either ;^)

macatlin1,

Did your project specify no glue to be used or was there problems with the wood glue sticking to the baked wood?

Thanks

OldWoody,
How about another image AFTER you have worked the ‘roasted maple’? I would love to see how that caramelization comes through.

The wood was originally air dried for one year at the Amish Mill I use. So I did not bring it down to 4%, nor check its value. I am preparing to work some of the material tonight and will post updates on conditions and pictures as I proceed. I plan to make some cutting boards by curve sawing and replacing strips of veneer between the slices…..should be interesting
