[Elecraft] Handle replacement on K3

[Dan]

Although, properly designed and tightened fasteners should not come apart
when you don't want them to, in practice any screw can come loose at any
time. Whenever I put together any screw or bolt that I do not expect to take
apart routinely, I use Loctite or fingernail polish to 'lock' it in place.
When I built the K3 (#4515), I used that on a few screws/nuts, specifically,
the handle, the feet, the support bail and the ANT1 and ANT2 hold down
screws/nuts. I wouldn't go out of my way to use the stuff, but if you have
any problem, just use that. I did not use them on any connector that needed
good electrical connections or that I expect to take apart from time to
time, e.g. covers, side panels, stand-offs.
 
Best way is to put a drop on the threads INSIDE the nut and then attach it
and tighten it, then place a drop on the exposed screw/bolt threads. If you
are concerned about electrical connection, then only place it on the exposed
screw/bolt threads after tightening it. For the handle, feet and bail,
electrical connectivity are not a concern and you will never expect to need
to remove these items. IF you DO need to remove them, they can be removed
with only a moderate amount of extra effort and it does NOT destroy the
threads.
 
To be thorough, there are two different types of Loctite. The usual is
designed as described above and is essentially fingernail polish. The other
type is a much stronger type for where a near permenant bond is required.
This may destroy the nut/bolt if removed, altho some (epoxy) types are
designed to be removeable after heating to 400 degrees.
