Dan, the sleds are made from Paduck for the main part of the sled and the runners are of soft maple, well except for two of the sleds since I ran out of maple and tried something that looks terrible. I had some 1/8 baltic birch ply and painted them white with clear glitter. So everything is natural wood and I now have a place in Springfield Missouri where I can buy hardwoods.
As for the green machines, well everything we have bought has come from Grizzly tools, with the exception of my saw which is a Shop Smith.
Hope this answers some of your questions.
