FlyBaby OK, I see now. I have a Dremmel with a chuck and 1/32" bit. That's how I drilled the aluminum on the rear deck. Where can I buy some 1/4" X 20 cemented nails? Aircraft spruce dosen't have them. Steve, at the risk of sounding critical, each time you send the List a message I'm also receiving an additional "blank" message from you with an attachment. I never open unexplained attachments. Is this something you're sending us? If so, please advise what it is. If not, you may have a configuration problem with your email program. Tactfully as I can be, Darrel
