I just dug my old blades out of the snow and found that they are
delaminated but I think that they could be wet out and glued back
together and then lam some glass over the top and they should work
for a test blade.
I also have a 4 blade hub and set of blade blocks you could use.

That sounds great Ken. A catastrophic failure on the dyno is no where
near as bad as in the air :)

Yeah, but even on the dyno a catastrophic failure would still be very
bad. Those
blades are really suspect; no telling what the "uncontrolled heat
treatment" did to
them. Perhaps the hub and blade blocks could be re-used if one could
scrounge up a
reliable set of blades. Otherwise, get a "real" club prop.

I need something adjustable.

A good safety trick would be to rig a dead-man switch with a lanyard.  Tie
the other end of the lanyard to a stake in the ground.  That way if you
throw a blade and the dyno starts jumping around it will kill the engine on
the first jump.
