I have decided to add a lamp post and generator to my wobbler engine I finnished a while ago. Here is the lamp for the top of the post.

Next to make the post and base.

That's a very nice looking fabrication david. Well done.

Getting on a bit with lamp post.

A good job on your lamp, interested in how you made the lamp cover David.

Hi

Bob I

had a go at cutting out the shape and silver soldering the join but it started to melt although I used a low temp jewlers solder. I had a go at lead soldering it but it was a pigs ear.

I then made a wooden press tool from a piece of oak on the mill with a couple of pinns to locate the two halves. I anealed a piece of brass and pressed it in the vice with a small amount of getting it worked well.

A lot of work involved getting the shape with no joints, well done Dave.

Just a bit nearer. Made part of generator to power the lamp post. Cut a plate to mount the motor on. Made a strip and end cap and soldered together. The cap was anealed and spun on the lathe to make the shape on a former.

The retaining lugs were bent and drilled and a ferrule made and soldered for exit for wiring to lamp.

Very good work David, l like the former as well.

I'll be interested to see how you link it all up with your mini oscillator

Just had a look at your picture file and the boiler snaps.

You've made a really good job of it, looks great

I have made the bracket to support the motor/generator and decided to check out if it works ok.

I powered up the wobbler and no problem.

The output is 3.2 volts and so time to Finnish the lamp etc.

Nice work!

Both mechanical and fabrication. A pleasure to behold

Great work David,

It's a wonderful looking lamp.

I also really like the wooden former. Good job.

ATB,

Finnished the lamp post. Painted polished and made the globe for the LED just needs wire soldering on and insulating.

David

[John MCParticipant @johnmc39344]

lovely job, what LED did you use?

John

[David George 1Participant @davidgeorge1]

Hi John I bought them from RS

3.2 V White LED 5mm Through Hole, Nichia NSPW515DS

I had to turn the flange off the base of the LED body so they would go through the tapped 6mm hole.

David

[David George 1Participant @davidgeorge1]

That's it finnished at last.

I have had the first run since completing it. Hope you like it.

What can I do now I am trying to think of something to make, maybe a more complicated steam engine.

David

[geoff walker 1Participant @geoffwalker1]

Well I like it David. Looks great, and as I said in an earlier post the boiler is superb.

Well done

Geoff

I'm sure you will get some suggestions for your next engine. Have you made one with a slide valve. A lot of people go from the simple oscillator to a simple slide valve engine
