I suspect you are right, since the website lists it as an "Adhesive".

Loctite 425 appears to be the only one they recommend for metal to plastic.
It is Cyanoacrylate based. It may not be that much different from the plain
old CA glue you used, except it is a pretty Loctite blue!

Re: [Elecraft] [KX3] Re: Kx2 paddle issue

[Ron D'Eau Claire]

Hi Josh: 

When I bought Loctite I had a choice of only two, red and blue. So I just
looked and that's all the Loctite web site lists now (they do have a variety
of glues and other chemicals but I am looking at threadlockers). Red Loctite
requires heating the screw to 500F to remove it. Blue Loctite can be removed
using hand tools. They do say they are not "recommended" for use on
plastics, but I believed they meant securing plastic threaded parts. In my
case it was a steel screw and nut so I used blue Loctite on the screw
threads. A tiny amount of the Loctite must have flowed onto the plastic hole
in the parts the screw and nut were securing. That was enough that resulted
in slow disintegration from a hole for a #4 screw out to an inch more in all
directions. 

I'll continue to use a drop of CA glue since I've never had a screw secured
with it come loose yet they are easily removed when needed. 

73, Ron AC7AC

There are something like 40 different formulations of Loctite Threadlocker.
It's a great product *if* you select the correct one for your application.
The wrong one can be a disaster.

Re: [Elecraft] [KX3] Re: Kx2 paddle issue

[Tom Francis, W1TEF]

Kent and Wayne,

I have not had any success with Loc-Tite.  This is strictly an 
engineering issue - the screws are too short
to produce enough torque to hold the contact posts in place - its as 
simple as that.  Longer screws help,
but again, the length of the contact posts and small diameter of the 
screws that cause the problem.


I've gone through three of these paddles and finally gave up - its a 
terrible design and based on others that
have posted here and some friends who have experienced the same 
problems, it seems to be an ongoing
issue.  You should not have to add Loc-Tite to a set of paddles of this 
type.  And it's not like Elecraft is not

aware of the problem - I've had it from day one as have others.

Other than that, I love my KX3 and KX2. And I like the KX3 paddles - 
those seem to work just fine.


Just one of thsoes "little" annoyances, but it should be addressed 
because its little annoyances that create

negative product impressions.

 Very best regards,

Tom, W1TEF
Lexington County, SC

Loctite Blue worked for me.  Some prefer Loctite Red.  A last resort 
would be JB Weld.


Once adjusted to the operator's taste, the KXPD2 is a very nice little 
paddle.

Re: [Elecraft] [KX3] Re: Kx2 paddle issue

[Ron D'Eau Claire]

I avoid Loctite after using it to secure a steel screw and nut holding a
plastic part. Over the next six months the plastic around the screw
disintegrated - crumbled. That was several years ago. Perhaps Loctite has
changed the formula, but I haven't succumbed to making another test.

I found that a small drop of thin (not gel) CA glue (a.k.a "superglue") on
the threads of a screw works very well, yet the screw can be removed later
if needed with little effort. The threads do not need to be coated. Just a
small amount where the screw enters the threaded section, or a small drop on
the end of the screw where it exits are all that is needed.

You may want to reconsider using Loctite Red (or Blue), the highest strengths.  
If you ever want to disassemble that part of the XDP2, it may take heat and 
excessive force to loosen.

Loctite Purple is probably more than adequate for the securing of the posts.  A 
tiny dab of Purple on the end of the screw threads worked great for me.
