Underneath the Lantern - Dynamo Lighting

Underneath the lantern - Dynamo Lighting

“Underneath the lantern by the barrack gate
Darling I remember the way you used to wait
Twas there that you whispered tenderly
That you loved me
You'd always be
My Lili of the lamplight
My own Lili Marlene”


"Das Lied eines jungen Soldaten auf der Wacht" copyright 1937. Lyrics - Hans Liep, Music - Norbert Schultze

With the PMR Dynamo finished , (still deciding on paint colors) there was something not right about the light hanging at the end of two wires, lying next to the dynamo.

Since I’ve already cleaned and reorganized the shop, installed a 220V line, assembled a 2 ton shop crane and read the manual 25 times - all in preparation for tomorrow’s lathe delivery, I needed a project.

A lamp post. A classically- styled lamp post! Some searching located similar posts that the model train guys make. Thanks to them for the shade idea.

K&E’s line of brass tubing will perfectly telescope in consecutively part number order. Like this:









First, I annealed the smallest diameter ( ⅛” ) tubing



Then used the spring-type tubing benders to make a gooseneck. The bend radius was carefully chosen (whatever round piece came out of the scrap box first)



Now we have the post parts.



These were at the hobby shop. They may be a bit small, proportionately. They only had this scale but Plastruct makes them larger or, once the new lathe is running, I can turn some that are a better size.



Drilled to fit the ⅛” tubing.





Next, a base. No lathe, but a bit of brass from the scrap box, in an R8 collet on the Bridgeport. Round forming tool.



Then turned over in a v-block. Drilled and reamed for the largest (3/16”) tubing.



Loctited on the outer tube. The part of the tube below the base will fit into a 3/16” hole in the Dynamo baseplate.



The three tubes loctited.



After paint, the lighting will be one of these micro-led lamps. This is like a dispenser. Cut one off the string. Solder tiny wire to the leads. Thread through the inner, gooseneck tube. Ebay. Less than $5. Free shipping.







Best,
Stan

That came out really well Stan. Will you mount it to the same base as the dynamo?  Will need a pic of that too of course :)

A concise and fun build, Stan. Nicely done.

Oh, and this reminds me of a guy who was helping me get my shop fixed up and repeatedly called my Bridgeport a "lathe".

A man who called himself a handy-man and was old enough to have had shop class in school. A Kentuckian...

Cleverly done, indeed. 

That telescopic tubing has all sorts of uses in modeling.  I believe their square tubing telescopes as well and that opens the opportunity to provide length-adjustable rotary drives.

Google images offers all sorts of options for other designs such as the art nouveau-ish one below.  Too blingy for me but...

Thanks, guys.
Bill
I've made a new baseplate which mounts the mill engine and dynamo. Drilling a hole for the post and a channel on the bottom for the wires. They'll exit under the dynamo's contact screws.

Marv
Too blingy for me also. I wanted a more "industrial look. The square tubing also looks like a natural for a telescoping crane arm (if one were inclined to build one.)

A friend came over when I got the Bridgeport. He said "nice drill press"

Nice looking lights. The details always make a good impression. I made some similar for my LGB garden railway many years ago. The shades were also brass and they used some LES (I think) lamps.

One is just visible in the background of this picture.

Thanks, Phil. Once it's painted, lit and in place it will, hopefully, look even better

Nice looking accessory. It will be interesting to see how it looks when powered by the dynamo. I wonder if an old-time incandescent lamp would look more "authentic", perhaps with a variable color temperature depending on voltage and a bit of flickering. I'm sure I still have some "grain of wheat" lamps among my HO train stuff.

Very cool Stan!
How much of a load will this be?  Probably not a very heavy load with only one LED.  But it sure will look cool having your dynamo drive something real!

And a great 'waiting for the lathe' project!

It's getting close... :)

I have both led and some of the "grain of wheats" to play with.
Still need to relieve the spring tension on the brushes as the drag is a bit much for the mill engine. It runs well, but slowly.

Well...
In this one thread we have seen you drill a hole with it as well as turn a part with it. So, is that Bridgeport a lathe or a drill press?  :shrug:

I've been without a lathe for a week. Withdrawal. I've reverted to three years ago when I started to learn machining. Just had a mill; no lathe. I built my first engine with the mill so this is déjà vu. Today is lathe delivery day.

As everyone says, a nice quick project.
I like the use of the telescoping tube. Didn't know you could get it. worth filing the idea away for future use.

when it's up and running , perhaps a photoshoped picture of Zee in his tutu under it? ... for that true Lily Marlene look? :Jester:

yours in fun

I believe that Zee charges a royalty for any appearance in the tutu.

I've always preferred Vera Lynn's version (1939) to Dietrich's anyway.

Ach, Himmel, nein, nein, nein.  An Englishwoman singing Lili Marlene!  It's a sacrilege.

To truly appreciate that wonderful piece of music it must be sung by a sultry woman with a raspy voice in German, the seductive language of love and poetry.  [Well, ok, maybe that last is a bit OTT, German being more the language of command than love.]

OK. I'll agree in the original German. But, there's just something wrong with Dietrich doing this:

Agree.
As for the last part...you can replace the 'German' with any language or none...and it still works.  :naughty:

I believe that Zee charges a royalty for any appearance in the tutu.

Not necessarily 'any'. It's the audience that sets the price. For (nearly all) you guys...you can't afford it. Free for a special lady we all know. Maybe even free for Marv...so long as there's video to document his reaction...whatever that might be.  ;D

Sorry to trash your thread Stan...but my name was invoked.  ;D

I was wondering what was that "Schlitten" she was singing about. So I found this:
http://de.wikipedia.org/wiki/Schlitten
 
I think I first heard that word in a late night interview with Danny DeVito, who said he had to ride the "Schlitten" down a ski slope. I found a reference to it, and him:
