Fingernail polish uses acetone which, of course, will soften *some* plastics, but unlike the solvent in Loctite, acetone evaporates completely and the end result is quick-drying, chemically stable coating.
Of course there is always Glyptal which uses xylene for its solvent. That, too, will soften some plastics. But it, too, dries to a chemically stable state, unlike Loctite. I don't know what Loctite uses. 73 Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Phil Kane Sent: Friday, December 28, 2012 3:42 PM To: Elecraft Subject: Re: [Elecraft] Problem with a K3 screw On 12/28/2012 11:08 AM, Ron D'Eau Claire wrote: > Instead I borrow a trick from my post WWII aircraft service days: > paint.

How much and what type of solvent does the fingernail polish carry as compared to LockTite? My preferred solution is to use nylon-insert stop nuts, which I learned about when I worked at the Douglas Airplane Works for a brief time. The local ACE Hardware outlet carries them in all sizes. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
