Hi Folks! For your viewing pleasure, I have just published a profile on European Yew as part of my ongoing tonewood database. As always, improvements, corrections and additional information/ your own experiences are much appreciated- I'll update the profile citing you and linking back to you! This may be a little contentious and but no means complete. I can't link pics directly to here so do pop by to http://guitarbench.com/index.php/2009/0 ... -database/ for the full Visual presentation. As always, I present the text portion of the interview for your consideration- although I do highly recommend popping by to see the pics! Warmest regards, Terence http://www.guitarbench.com Taxus baccata| Tonewood Profile | ”Yew” Tonewoods Database All pictures - Click to enlarge! Please email with any corrections/ additional info We aim to keep each profile as complete as possible & your help is appreciated! European and Pacific Yew are very similar species, in terms of physical properties. Quick Facts Scientific name: Taxus baccata Trade names: Yew Janka: approx 1,600 lbs-force Uses: Back & sides, drop tops, veneer RIYL: Maple, Walnut Bling factor: Often very plain Availability: Limited CITES status: Not listed. No restrictions Natural History European Yew is a very slow growing small/medium evergreen attaining heights of 28m and a trunk diameter of up to 4m. Some stands in Scotland are estimated to be approximately 2,000 years old. The fruits are soft, bright red and berry-like. Whilst the seed itself is extremely poisonous, the aril not harmful and very sweet tasting. The Yew has been exploited throughout history for it’s timber as well as for taxanes. In the Middle Ages, yew was extensively harvested for bowstaves whereas more recently, chemotherapy agents called Taxanes have been extracted from the leaves of European Yew & bark of the Pacific Yew. Status This species is threatened by disease as well as demand from pharmaceutical companies. However, conservation efforts are ongoing. Physical properties European Yew as a narrow, white sapwood which is sharply demarcated from the orange-brown heartwood. It takes an excellent finish, but is prone to tearing especially in cross-grained material. It has a Janka rating of approximately 1,600 lbs-force and a specific gravity of 670kg/m3. It can be stable and durable although the sapwood is susceptible to woodworm attack and many newer trees have spiralled trunks creating problems especially when bending sides. As a tonewood… As a tonewood, Yew has been only infrequently used and predominantly by the UK luthiers. In my experience it is modestly difficult to work with, although care needs to be taken when bending the sides. UK based luthier Adrian Lucas says “the colour ranges from pale brown to purple in the heartwood and a creamy white in the sapwood. The grain patterns are quite striking as this is a softwood, being evergreen, although it has a density higher than many hardwoods.It grows in quite a twisted fashion and has a lot of knots and cracks. This makes it difficult to plane without tearing, so it’s best scraped and sanded. It’s also quite difficult to find in large sizes that are free of large knots and cracks, so I tend to make multi-piece backs using only the clear wood.” (read more about Adrian Lucas here) Subjective tone… I have found it to be an excellent tonally with a maple like clarity but with very sweet, intimate and appealing overtones. Adrian Lucas finds it “imparts a woody, springy quality to the tone of a guitar.” Availability Very limited.

your opening a whole can of worms on that one as americans and british can get into some quite heated descusions about the american and english sycamore. but i should point out now that the only TRUE sycamores we have in the U.K. is london and oriental plane. what we call sycamore here is a type of maple called acer psudoplatinus (means false plane) which tends to be called euro maple in the states. but we call acer campester and acer platinoide euro maple. in fact a more accurate name for english sycamore would be great maple which it is called in scotland and some parts of england. confusing yes but i am sure terrence will shed some light on this one. this should be interesting i am looking forward seeing the results, joel. |
