Average size is about 8x10 on Army, 8x13 on Family name plaques. Most average about 0.75" to 1" thick. (Thickness varies depending on shape carved in MeshCAM). As far as parquet flooring, it might be fine for an engraving project. But for 3D scuplting, you need something more than an inch thick to start out with. If you want something carved, send me your artwork and I will see what I can do with it - as far as creating a tool path.
Just send as an attachment to adprinters@bellsouth.net BE SURE TO INCLUDE IN SUBJECT LINE: WOOD CARVING, otherwise your email may end up in my trash folder unread. (I get a LOT of junk emails everyday!). Happy New Year to all my Mach friends!
