Jordan LaMay sells cedar, basswood and white pine, for decoy carvings He’s on face book, and will ship.
For my bodies I use cedar or white pine, for the heads basswood.
Wilton power arm, they may not manufacture them anymore, you can still find them used.

Here’s my keel design I use. I can wrap then decoy line around it, and the belly cutout I seem to get more movement. If I need weight or less I can do that to.
