PLEASE HELP

Bob,

I see you are venturing into the "sling wing" area.  Fermis is right about "pinning" the blade as your best option.  A section of paper clip would work well.  Go with something stiff, stay away from wire for something like a heavy rotor blade.  Look forward to seeing your build and meeting you in the near future.

You should be able to get a pin vise and wire gauge drill bits from any well stocked hardware store. I've seen them in most chain stores (Home Depot, Orchard Supply etc).

Bob,

You need to invest in a Dremel tool with variable speed.  It really does come in handy for lots of projects besides model buidling.  I don't know how small you can get drill bits at Lowes or Home Depot, worth a visit.  Also don't know if Hobby Lobby would have a pin vise and bits.  Might visit Harbor Freight behind Picadilly.  I just came offshore today or I'd invite you over and use my tools to pin your blade.  You could also check out Big Boy Toys.  Micro-Mark Tools always has sets on sale.  Send me an E-mail if you want to call me this week at work and I'll send you the local number.
