I seem to recall that just about any straight grain wood - hardwood or
softwood or both laminated together will do the job.

Dear Brian,

Sorta-hard softwoods such as fir, do just fine with the VW. Trailing
edge can be relatively blunt and still get the job done. Leading edge
-- the outboard foot or thereabouts -- needs to be glassed then fitted
with a slippery tape. But rpm is definitely a factor. Use the proper
cam on a seriously over-square engine and a tip-speed of no more than
880fps, you can even use spruce... but ONLY if you are running a
flywheel. Maple remains the best choice, not so much for its
durability but because of its MASS. Turns the veedub into a real
chugger.

Wait until you see what Bruce King & Steve Bennett have come up with
for the BK1.3. One of the engine options is a surprisingly light-
weight package that's all wrong... according to the instant
experts :-)
