32 guitars from a cocobolo beam 

I found this fun to watch.

I liked that he took the time to maximize the wood to get the most out of it rather then wasting it. I had a precious plank of spruce suitable for a stack of top plates I miss cut for not being attentive: brace wood now. Actually that perfect three inch slice I took off the good edge became a couple necks.

Stephan, what is it you don't like about Coconolo?

It makes some people sick and it sounds like sh^t, but dealers in Japan won't sell maple and cypress guitars for as much because they have fixated on Cocobolo and Brazilian. And I dislike both of them, except Brazilian bridges.

If you become sensitized to Cocobolo you can get extremely sick with both respiratory and skin conditions. It effects most people, getting cocobolo fine particulate in my shop is something I never want. It's toxic wood.

It's to the point where I may completely stop making any rosewood guitars because I favor Cypress sound and love the transparency of Maple. I also have a local supplier who finds figured Japanese Cherry that I'm stock piling. Other than bridges I just don't enjoy working with rosewoods.

Research it:

https://www.wood-database.com/cocobolo/#:~:text=Allergies%2FToxicity%3A%20Notoriously%20allergenic.,%2C%20and%20asthma-like%20symptoms.


Cocobolo is becoming rare and the slash and burn politics in Brazil are reducing habitat every year. It's my personal belief that Brazilian and Cocobolo are blood commodities and I don't want anything to do with using mass quantities of it. I don't have any Brazilian bridge blanks.

I'm not going to participate in that mentality were the guitar collector is in the philosophical space of - Oh I know the wood is rare, but I just want to get mine before it's too rare. - Cypress is easier on the planet and grows faster and in more places.








From the page:

Odor: Cocobolo has a distinct spice-like scent when being worked, which some find unpleasant: though it has been used in at least one women’s perfume.

Allergies/Toxicity: Notoriously allergenic. Reported as a sensitizer; can cause skin, eye, and respiratory irritation, as well as nausea, pink-eye, and asthma-like symptoms. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Cocobolo is in limited supply, and is also in relatively high demand, (for ornamental purposes), and is likely to be quite expensive. Prices should compare similarly to other rosewoods in the Dalbergia genus.

Sustainability: Cocobolo is listed on CITES appendix II under the genus-wide restriction on all Dalbergia species—which also includes finished products made of the wood. It is also listed on the IUCN Red List as vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.

Common Uses: Fine furniture, musical instruments, turnings, and other small specialty objects.

Comments: One of today’s most prized lumbers for its outstanding color and figure; yet also one of the most infamous for its difficulty in gluing, and its tendency to cause allergic reactions in woodworkers.

Also, there are a few misleading reports of Cocobolo’s Janka hardness being only about 1,100 lbf, and it’s modulus of elasticity at only about 1,100,000 lbf/in2: which is almost certainly either a typo or a different wood than what is commonly called Cocobolo (Dalbergia retusa). Reports indicate that Cocobolo is stronger and denser than Brazilian Rosewood, and that is the basis for the strength values (bending strength and modulus of elasticity) that are quoted at the top of this page.

Specific gravity is used to predict the hardness of wood with a fair degree of accuracy, and given its incredibly high density, (it sinks in water: see video below), Cocobolo’s hardness (and other strength properties) is most likely several times higher than the 1,100 lbf which is sometimes reported.

I enjoyed that Ethan thanks for sharing. What a great channel! I ended up watching the soundboard one and the action height one which were both really facinating.

I was pretty surprised to see he rarely wears a dust mask. Looks like he has got amazing extraction but still... I think I would put one on when running wood like that through a bandsaw.

Cheers.

He's an idiot for not wearing a mask with Cocobolo

He had the log two weeks and his sinuses are messed up through the entire video

For the amount cocobolo costs you could by twice as much cypress and have tons of money left over for a several weeks supply of pharmaceutical grade coke.

I have lung issues but zero alergies. I pull my saws outside to cut up problematic woods. Got three split billets of WR Cedar for tops to resaw, outside for sure, still use the dust extractor, and one micron filters on my respirator.
If your gonna be dumb, you better be tough ;)

I tried to watch the guys setup video but he was using too many words and too much time saying nothing and wasn't entertaining enough to keep my attention. I'm an information junky but I need to mainline it, give it to me without the fluff.

There’s a guy on YouTube called Nate Marling he makes fishing lures. His channel is called Marling Baits - it’s more interesting than all the guitar makers
