Rich,
It's the loading coil for a Lionel train. Santa Fe if I remember correctly.

Hi All;
Can someone here either direct me to a site or knows what this device is used
for or associated with.
It is made by Lionel, C-114-A, Coil, loading.
I know what the model is, hi, but would be nice to know what actual military
unit it was used with.
Many WWW searches really found nothing.
Any help will be appreciated.

Dan,
my notes say it's 8-36 UNF thread, yet another oddity of the 39x's. If you
had the tap you could epoxy the hole and drill and retap it but a
replacement knob can be gotten cheaper.
Sometimes you can smear some JB Weld across just the damaged area, let it
firm up a bit, and then use the setscrew itself as a tap, then remove it and
let the JB cure. If your lucky it can give the setscrew the little extra
bite it needs to do the job.
That phenolic insulating shaft on the 390 is pretty tough, I wouldn't worry
too much about hurting it.

Maybe you can just buy a new knob from someone here. I have done that, usually a few bucks each.

Just remembered another quick fix......
Try wrapping a layer or so of plumbers Teflon pipe thread tape tightly over
the setscrew, it'll build up its diameter and make it fit tighter.

Hi John
Coincidentally, I have a question about JB Weld. I just used it to repair a
small folding table which was inadequately glued to start with.
I'm more accustomed to regular and quick-cure epoxy which is clear.
Had some small tube sets of JB weld somewhere, but lost track of it. I
picked up some at Pep
Boys -- big box "J-B Industro Weld, Cold Weld Shop Size"
This stuff when mixed is medium to light gray. Are all of the J-B Welds
that color? I also picked up the small tubes of the quick set version.
That grey looks very similar in shade to the "right" shade for R-390 front
panels. Anyone try it to detail out a chip? Might not even need touch-up.
I used to assume J-B was the same basically as regular epoxy glue, but
possibly better quality. Must be something very different as it doesn't
have that characteristic annoying aroma. It also cleans up a heck of a lot
easier.
Barry

Apparently they do make #8-36 helicoil inserts. I found the helicoil taps
for them but haven't found the coils. It would make for some good threads
if you could find them (and have the knack for drilling, tapping, and
inserting them).

I was looking for some JB Weld last night at a local AutoZone store. They
didn't have the usual stuff, but they did have the Quick Set version. I
didn't get it because it appeared to be more of an epoxy rather than a
filler. The package didn't mention it was machinable like the regular JB
Weld is. Anyone know?

Barry,
I didn't know there was a quick set version, all I've used so far is the
regular stuff which is dark grey after mixing. The next time I'm out
shopping I'll look for the quickie stuff out of curiosity.
Check out http://jbweld.net/index.php especially the FAQ and technical
section, it has some of the info you seek.
Yes, I've also noticed that it is a pretty good match for the front panel
and its shade can also be altered depending on the resin/hardener mix ratio.
It also can be thinned with the usual paint solvents.
They call it a "steel" epoxy. The MSDS info didn't say anything about steel
but the two components do contain calcium carbonate, iron powder, and barium
sulfate in large parts which probably account for it's hardness and
machinability.
They also said in the FAQ section that the quick set version is only half
the strength of the original JB, which agrees with my thinking that the
longer set time epoxies are inherently stronger. I'll use quick set epoxy on
tiny parts and things that don't require a lot of strength but use the
longer cure time stuff elsewhere.
I just epoxied part of a hair dryer power switch back together where the
switch contactor broke away from the finger slide part of the switch. It was
an easy fix but I couldn't believe how freakin' weakly they designed the
broken joint; for lack of a bean sized amount of additional plastic they
created a very weak link. So besides gluing the original break I also filled
in the entire hollow end of the joint and now it's strong as a rock.
73,
John
