We have chosen to work primarily with Aspen, Poplar and Maple as the raw lumber in our cores. Aspen and Poplar exhibit both low specific gravity (weight) and high strength to weight ratio. Aspen is slighlty lighter, Poplar machines cleaner and is slightly stronger, while Maple is chosen for cores where light weight is not paramount but the ultimate strength and "pop" are desired.
Coming later this year are Custom tapered cores and sidewalls where we will cut your custom thickness and shape specifications, as well as our new "Feather" wood/composite cores that are the lightest out there - period. Expensive, but if you want the best, these cores are what you want.
