Very neat Rich!

I wonder if laminating a blank together out of a few stips of wood with some fiberglass cloth and eopxy resin between them would stiffen things up. You know sort of like a wood and epoxy sandwich.

Very ingenious with excel and access too. Rich-cam.

I saw the laminated boards that Jacques and Scott were using, I was wondering how they laminated them so that they were weather proof and wouldn't come apart. The seem to work well and I'm sure that they both did their homework. For these small blades, I'm not planning on keeping it as simple as possible, load a piece or pieces of dimensional lumber and carve out a blade. I think that at this radius most woods would work well, however, Hickory, Elm or Ash would probably make nice strong blades. I have access to lots of scrap pine, so it would be nice if I could use it. Rich Hagen

I have Full 1" thick x around 2" wide clear hickory, in 12~16" lengths.
I don't have any 'good' stepper motors.
Hmmmm...

The NEMA 17's are small, but as Ratometer found out I do have a bunch of them. RichHagen (no-spam) at Juno.com
