Title: Quick Loco Project
Post by: jonathan on November 15, 2020, 07:50:51 AM
Taking a little break from scenery.

Here is a brass B&O S-1a (2-10-2) which I've posted about before:

I installed a working reverse light, using some gold plated connectors:

Unfortunately, these connectors, which seemed small to me at first, turned out to be a bit bulky--awkward to manipulate, hang too low, and so on:

While shopping for scenery material at a hobby shop, I ran across these micro connectors from "Scale Shops" in Prescott, AZ.  As you can see they are quite tiny:

They are gold plated, there are 20 pairs of connectors for $12.  Had to give it a try.

The wide portion of the connector made it easy to clip on a heat sink and solder to the wires:

I was able to shorten the wires and move everything in close:

Now the connection is easy and doesn't interfere with trackwork or the drawbar:

And it works!

OK. now I have to get back to scenery. Just made 171 new trees.  Will get back to the layout stuff soon.

Nice. If you do another loco, you could chuck the connectors in a drill and spin it against a file or sandpaper to knock the corners off.

Very nice work. Something I cannot do anymore.

 :) As I get older, I try to knock out tiny work.  I know the day is coming when these little projects will get too tough. Even now, getting enough magnification to see what I'm doing, is challenging. I have discovered soldering magnet wire to SMDs is darn near impossible.

Len, I have three more brassies with the same set up.  I will try spinning down the plugs to round 'em out.

Thanks guys.

Jonathan

Man, if I tried something like that, I'd end up with a chrome ball
trailer hitch the size of that penny on the draw bar !  Nice work  Jon.

Thanks for the pics.  Beautifully weathered loco by the way.

Thanks, Grumpy.

I took Len's advice and tried to put a plug in a chuck and round-off the insulating plastic.  Also tried shaving it down with a razor.  Neither method was creating a good look for me.  The plug is just too small.  However....

This is a Q-4b that needed a new smaller connector for the reverse light:

I found it pretty easy to clip off that bit of plastic insulation.  Then I could cover the whole plug with shrink tubing.  This looks okay to me:

Works:

Thanks, Len, for putting my noodle in motion.

Jonathan

Who needs a plastic insulator anyway when you have heat shrink?
