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! -- Jim Maher, Illinois |

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. -- Rick Wood TheWoodYard.com |

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. -- ian | "You can't stop what's coming. It ain't all waiting on you. That's vanity." |

I never heard that Gibson was actually convicted, just accused. There is a big difference. The settlement of the case, as I understand it. . Donald Carr Re: United States v. Gibson Guitar Corp., et al Gentlemen: Enclosed please find the case-closing letter sent today by this office to SAC Nicholas E. Chavez, Southwest Region I U.S. Fish & Wildlife Service, memorializing the conclusion of the Government’s investigations into potential Lacey Act criminal charges against Gibson and its current or former officers, directors, employees or agents. Your clients and the affected individuals may consider this to represent a final disposition of any and all potential enforcement actions related to the issues described in the case closing letter.

Michael: A good summary of the final agreement is here: 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. -- ian | "You can't stop what's coming.

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. 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: Closeup: |

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! |

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 |

So here is what I have found so far: after jointing, planing and cutting….the color is all the way through the material. It machine as nicely as the other piece of soft maple before baking. I have a jig yo make and will probably mix the original and the baked wood in a cutting board/trivet set. Here is a picture of a piece before and after the baking. The baked piece has been S4 machined. |

I’ve used roasted maple in a few of my projects posted here, and have a couple hundred BF of it out on the racks. It’s nice stuf, easy to work with. Weighs a bit less than plain maple, and sometimes acts a bit more “brittle” for lack of a better word. Sawdust is very fine and tends to stick to blades, bits, etc. Smells nice when cut! -- John, BC, Canada |

Great post – Im interested to try this, I have a nicely figured semi-curly maple board I discovered in the stock at HomeDepot one day and brought it home. How can you figure out the moisture content of the wood? I bought it at least 4 months ago and its been sitting in my garage, I would assume drying all the while. Can I estimate it based on a formula or something? -- Joseph, Irvine CA, @palas_woodcraft on Instagram |

I roasted some maple yesterday and got mixed results. I learned a few things in the process. The color of the underside—toward the heating element—was nice, roasty brown. It was almost a little too roasty for my comfort. The other side was much less brown and more gray. I wasn’t happy with that. First, the wood I used was much thicker than what OldWoody used. Mine was about 2 1/8” thick, where his was 1 1/8” Also, I didn’t use convection. I did have the oven at 360 degrees F and left it in for 4 hours. I never saw any smoke at all—not even a whisp. You could definitely smell the wood though. I had the oven’s vent fan going the whole time and that helped. I want to be able to roast thick boards, so I might try a lower temperature and longer roasting time. I’ll definitely use convection for even heating. I might even put a cookie sheet on the lower rack to shield the wood from the heating elements. Here are some photos of both sides of the roasted board compared to an unroasted piece from the same board: -- Mitch, http://furnitude.blogspot.com Also blog at http://www.craftsy.com/blog/author/mitch-roberson/ |

I made a wood fired pizza oven last year. It slowly cools down after the fire is out. The inside dimensions are 32” wide, 40” deep and 16” high….. I’m going to have to try this after my next cook up. Wonder what roasted walnut would be like? |
#29 posted 01-15-2015 04:01 AM |
I realize this is an old post but I couldn’t resist getting in on this, even if I am a little late to the party. I’ve been seeing all this talk about maple and the one person who asked about walnut. So has anyone used any other woods, domestic and/or exotics? I have a lot of lacewood and and would be curious what that would look like as it already has a VERY distinct figure to it. Another thing I’ve been wondering is could same effect be accomplished with an electric smoker, obviously using just for the heat Nd not the smoke. I have one that doesn’t get on to 360*, but I could just as easily roast is for longer times. Just thinking out loud… Thanks! |

Well, if 360 is one of the magic benchmarks, the smoker is out; 275 is my max. Ill have to test this one day when the wife isn’t home. She’s not too keen on experimenting like this. I my still see what the smoker can pull off. I can see why the temp matters if it comes down to turning the sugars in the wood. I’ll be sure to post any test results. Thanks for the response! |

Are you using an electric oven? I am thinking that a gas oven with an open, although shielded flame, may not be a good idea? |
