Post subject: | American Sycamore Tonewood Profile |
Hi Folks! For your viewing pleasure, I have just published a profile on American Sycamore 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: Sycamore refers to different species depending on locality and I found researching American Sycamore a little more difficult than the other tonewoods I have already profiled. If you have an experiences or data to share, I would be very grateful. 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 Platanus occidentalis| Tonewood Profile | ”American Sycamore” 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! Sycamore is a term used differently in Europe and America. In the UK, Sycamore is actually the European Maple (Acer pseudoplatanus), whereas in the US, Sycamore refers to Platanus occidentalis/Platanus racemosa. To confuse the matter further, American Sycamores are referred to as Planes. Hence London Plane is Platanus × hispanica. Quick Facts Scientific name:Platanus occidentalis Trade names: Sycamore Janka: approx 770 lbs force Uses: Back & sides, drop tops, veneer RIYL: Maple/ Ash Bling factor: Figure is uncommon but displays large medullary rays Availability: Relatively Common CITES status: Not listed. No restrictions Natural History Platanus occidentalis is one of the different species of sycamores (planes) found in the US. It occurs mainly in wetland areas ranges from Northern Maine, Western Nebraska and Texas. Sycamores can reach large sizes up to 40 metres high and 2 metres in diameter. American Sycamore is recognized by a mottled exfoliating bark. The bark flake off in large masses, leaving the surface a mottled green-white and brown. This is due to the relative lack of elasticity which is unable to accomodate the growth of the trunk. Status The America Sycamore is not currently endangered- it has been extensively planted as a shade tree in the past due to it’s ability to survive in an urban environment. However, London Plane is now surplanting it as it is more resistant to fungus infection. Physical properties The heartwood usually displays straight, even textured fine grain which is pale reddish brown. When quarterswan, possesses a distinctive fleck figure. It has good workability but may bind on saws and may display high shrinkage with warping tendency. It has a Janka rating of approximately 770 lbs force and a specific gravity of 0.49. Air drying takes long….and like it’s cousin, is very stable in service once dry. As a tonewood… As a tonewood, it is moderately easy to work with and produces a striking guitar. Rick Davis of Running Dog guitars says:”In density, stiffness and hardness, P. occidentalis is closer to mahogany than to the maples. It can be as soft as cardboard, floppy and generally a terrible wood for anything other than pulp. Some trees seem to produce harder, denser wood and that’s the stuff for guitars. It may be somewhat tighter-grained but grain alone isn’t indicative of the better wood. I can only say that I weigh each board (by hefting it, not quantitatively), knock on it, push a fingernail into the surface — generally get a feeling for the individual piece before purchasing it for guitars.” “Quartersawing is essential for the sycamore look: the rays and fleck only show up when the wood’s pretty well quartered. Some is reddish in color and, in limited experience, seems to be very dense and stiff. But the light colored wood can be equally stiff, too. Or not. Individual pieces have to be evaluated. It’s pretty easy to work. Sands and scrapes cleanly, bends well, is easy on edge tools. It is porous though so use excess glue and expect to add an extra coat or two of lacquer. I found that resawing it was OK but it’s fibrous and tends to clog the lower guides.” Subjective tone… I would classify this wood as somewhere between mahogany and maple- good clean overtones like maple but with that punch and elasticity of mahogany. Rick Davis again: “Tonally I liken it to good mahogany: it’s more clean, trebly, and melodic than dark and complex. Projection is OK. The softer sycamore does not produce much volume and gets muddy; I avoid it. As with mahogany, I like to use it with Engelmann or European spruce rather than the denser spruces. I don’t think sycamore’s lightness of tone would couple well with, i.e., red spruce’s bassiness or with cedar’s or redwood’s darkness”. Availability Fairly good. Similar woods/ Alternatives Platanus racemosa and wrightii are also American sycamores which have similar properties to P. occidentalis. London Plane (Platanus x hispanica) and Plantanus orientalis are more common in Europe and worldwide and have their own profile coming up soon. “P. racemosa tends to be denser and stiffer than occidentalis. “ Tonewoods Database References: Wikipedia Fine woodworking: encyclopedia of wood Rick Davis, Running Dog guitars Pictures copyright individual holders.

Hi Terence, Good stuff on Sycamore, thanks for the profile. There are some huge Sycamore trees here in East Texas. Driving by them, I can't help wonder what glories are inside. Surely, a number of fine acoustic guitars are just waiting to emerge! Here's an OM finished late Winter: Attachment: otb back sm.jpg Attachment: otb back3 sm.jpg Thanks, Steve |
