Tell us about yourself!
A great puzzle mind blower and well done, sir.The species of wood is poplar, a typically used paint grade hardwood and very versatile in its uses for interior trim, furniture and model or prototype projects. The slight green tint, grain pattern, and clarity of the piece you used were the tells and the cambium layer remnant you planed off was also typical of poplar. Poplar is a wonderful and inexpensive wood to work with. Again, kudos, on your project.
