I know the feeling Derb!
Ive received so much help on this forum in advice, parts and supplies, even restores!
In the workshop forum, Outback just posted pics today of one he's working on for me.
So I've got a pile of blades that I'm saving up and am planning on doing a give away at some point.
Don't really know how to go about it, have contacted a couple members already for help when the time comes, but want to make it different than other give aways...
Structure it for more participation and sharing.
Still an idea in progress.

Good on you for thinking of giving back!
