Simple quesiion
 

Does it "hurt" anything to cut the 1/4" nylon wing bolts shorter? Right now they are about 2" long and I don't need all 2" can I cut them in half, or as deep as the threads go?

Thanks

you can cut them as long as they have about 1/4" or so into the threaded block or blind nut .

The bolts should extend through, or beyond, any securing device by at least three threads.

Thanks, that is what I figured, but I just wanted to make sure, on one of my planes they screw in nice and almost too easy, on another it is a bit more diffucult to screw in and I have a good extra inch that I may remove.

Aerowoof's response is correct.

I'll add that if you can find nylon bolts the correct length, they will fit better than one that is cut down. It is a chore to get a nylon bolt clean on the end after cutting it down. If you do cut it, use a razor saw and cut it as square as you can and don't over heat it and casue the blade to bind. Once you have the clean cut use a sanding block or fine file and champfer the end of the screw at a 30 degree angle. Do this stroking from the Od to the center so any flashing left will be in the center of the screw not on the threads.. Hardware store nylon bolts seem to be the toughest to clean up, and the Dubro black bolts seem to be the easiest. Last, don't make the mistake of using a die to try and clean the threads. It just makes a mess of things.

You can shorten them as noted above. One thing that makes it asier to get them started is to use a cheap hand-held pencil sharpener to chamfer the end. I do this whether or not the golts have been shortened. A small washer and an "O" ring keep them from falling out and getting lost too.

go to a hardware store and find a nut that threads on, run the nut on and then cut it to length. after you cut back off the nut and the threads will be cleaned up.

I recommend you to follow ALL the excellent above tips in the following order:

For bolts too difficult to turn, check for big missaligments.

well, I am not going to worry abotu cutting them, I did a woopsy, that is what happens when you try to rush stuff and are a little tired:eek: I just taped the threads in the hardwood, and I put a little thin ca in the threads to make sure they were a little stiffer, then, I gave it a few minutes for the ca to dry, then I was not thinking and decided to test them out one more time. A few hours later I went to go take the wing off, well guess what the nylon bolt got gled to the wood. I had to vice grip the bolt out in a few secitons then, I had to drill out the remainder and retap. It is done now, but darn that took some extra time.

Thanks guys

When you are finished tightening any assembly, three full threads must extend beyond the fastener. This is an FAA Regulation, but I like to use it for modeling as well as all the other things I do.

It would not sit well with me if a tightened up wing bolt were to wind up in the middle of a mounting block. To each his own.
