Like Terrellflyer, I have always used Sig easy hinges. I fly on an average of 5 days a week, (every day weather permitting). Between 2 and 5 times a day. I too have never had a failure. But what Minnflyer says makes sense. You know what they say, there's a first time for everything. I think I shall start taking the precaution of drilling the hole, can't take but a few seconds. You know an ounce of prevention. Always glad to help if I can. Garry
