Thank you for sharing very informative, I always wondered about what if a whole guitar was torrefied if let’s say I want to simulate really aged vintage one then it’s not only the top that aged? Just curious here 😅 i understand now that bending wood might be more difficult after the process so I think its practicality matter after all, imagine J45 style guitar but the whole guitar was torrefied vs origin vintage good survivor example
Cool. If somebody wants it can find a oven design and study on thermal wood on the Roukangas guitars site and why lower temperatures are better for instrument use. I hope that we will begin to see other wood species in thermal treatment being offered. Personal dream is to get a full thickness and heelless Les Paul with torrefied Okume/Spanish cedar and Sycamore for the body and torrefied Spanish cedar neck wrapped in carbon fiber and have the finished guitar weight around 6lb 10oz (3 kg).
👍 Another major benefit of roasting guitar wood is often overlooked... because it goes to the builder rather the player. Many of the medium to large size manufacturers have intonation warranties. Since builders have little control over what kind of environments their builds are taken into and often have to correct issues that might not even be their fault, roasting (the neck, primarily) it’s almost like an insurance policy for the builder. Nobody likes call backs!
Fascinating process Robert, thank you for sharing that. I had seen a Rob Cosman video on Birdseye maple where he had a board that had been cooked and I wanted to know more about the process . This video explains it very well .Thanks
Once again thank you for sharing your experience sir, starting for pickup alot of mahogany and put inside my chamber. Will weld some of plate build my chamber. Thanks Rob...
Would love to see some more torrefied apple, pear, and plum. Normally it's very twisty, unstable, stringy. Considered junk wood, and usually chipped for smoking. Torrefaction would make it stable for instruments. It would be hard to find large diameter pices, since trees are usually grafted onto smaller rootstock for pickers to actually reach the fruit. But they could be great for necks.
Great video. Now I'm daydreaming about a dreadnought with torrefied red spruce,Brazilian RW,and mahogany. It might resonate so much that you couldn't hold it in your lap while strumming :)
If I have a torrified top and neck with a non-torrified back and sides, will there be a problem with expansion of the woods at different rates? Thank you for all the videos and happy holidays.
I would imagine so because the back and side woods are a different species anyway. However, just keep your guitar at the proper RH levels and you shouldn't have a problem. Merry Christmas and all the best in 2020
Interesting. It seems like torrefied wood has more applications in home building, then in instruments. Another example of I want it, and want it now. Is this a problem for forestry? Where dried lumber is turned over far faster than forests can regenerate and recover? I'll stick to milling a nice piece of spruce, and let it adjust over a couple decades. 2 cents
I know a guy who does it in his home oven by tenting his billet in aluminum foil with several hand warmers. Hand warmers remove oxygen through an oxidation reaction. Home ovens are typically accurate enough to hit the needed temperatures and maintain them. His caution to me was to make sure the wood is really dry before. He apparently used the oven for an elevated temp drying step.
Great video. Concise
This video is fantastic!
Glad you enjoyed the video. Thanks for watching.

Thanks a lot for sharing your research and solving all our questions in a great way.
Thanks Robert for showing this video, great info!!
Great vid, man, so much to learn. Ok, Finland, imagine that, couple of hours driving from here.....thanks Robert, have a good one!

Nice video- Does he say, at 9:50, that torrefied spruce is not subject to humidity issues? or just some hardwoods??
Yes Torrefied wood is mostly Immune to Humidity, That's what makes its stable

Excelente!
Thanks Maestro! Give that shop
Dog some pets and scritches for me. I want to try some of this torrefied wood.

“Completely dry” but they are using steam to prevent combustion at torrification temperatures? I am a little confused.
temperature is lower for that process
torrefied - When you are walking down a small alley in Spain and find out first hand what 'the running of the bulls' means.
I wonder what would happen if cocobolo is torrefied. Would that remove most of the oil?

Btw do you have experience with cryogenic fret treatment?
Or floyd rose plates and pins?
Seems like it could make them a hair more durable.
Sorry, I have no experience in this area.
Would steaming add back in any moisture content?
Hum, I think that would kind of defeat the purpose of torrefication. It might work for furniture but I wouldn't do it for instrument grade wood.
watch the video again, he explains that
How exactly do you achieve 0% moisture in wood?
Where could we send wood inside the usa to have threated by a reputable operator?
Can I torrefy a spruce top at home?! 🤔😊
I wouldn't recommend it.

3 steps:
-drying
-torrifing for 3 hours
-? (you forgot to explain in the interview)
Otherwise, thanks for the video
The years are 1940-1950
That guy doesn't know much about guitars, lol!
Someone somewhere post a diy vacuum oven video. There has to be an affordable, safe way to do this in small shops
