I knock out the original blind nuts obviously. And threading the wood to take whatever nylon size I think suits the gear has so many positives that I don't bother using metal blind nuts for those nylon bolts.

Threading the wood is extremely easy. It's more than adequately strong. It grips the nylon bolts perfectly. There is no additional weight. Matter of fact, since I am replacing metal bolts and metal nuts with a couple of nylon bolts, there is a weight savings.

I also retrofit the wing bolts with nylon for all those reasons as well as a couple more. And don't use blind nuts there either. And nylon wing bolts are so much easier to use than metal, it's no contest. I taper the ends of the wing bolts and they find their holes by themselves.

Which reminds me............. I've flown my newest plane enough to know it's a definite keeper. And all my keepers get the nylon wing bolt retrofit. And I got nothing to do tonight so......... Think I'll go down and give her better wing bolts. see ya.........
