Baldwin Gas Mechanical Lamps

I have just finished a pair of these lamps for my Baldwin 50HP gas mechanical. One sat on the "hood" in front of the chimney and the other hung from the rear underside of the cab roof. The body is turned from solid corrosion resistant aluminium alloy.  The bit of wood was so I could take them to the Work in Progress night without risk of damage.

Nice work Steve...what scale are you working in?

Regards,

John.

Very tidy, Steve

LED illumination too.

Thanks guys.

It is 7.25" gauge which converted from 600mm gauge I make 3.26" to the foot. Not an ideal scale. The LEDs were sourced as filament automotive bulbs will vanish shortly in my opinion and these have a very long life - I bought a spare set too!

The lamp body is 72 of 73mm diameter I can't remember which.

Here is the "office" at the present state of building.

That looks really interesting Steve- I hope you'll post your progress occasionally. That is very much my kind of model engineering!

Regards,

John.

Hi John

Not looked on here for a while. I have recently equipped myself with some electronic gear so last night lit the lamps with the proper voltage from a bench power supply. I'll upload the picture of them lighting my bedroom from complete darkness.

Steve,

You need to take some viagra last thing at night.

It will stop you rolling out of bed.

Steve, you'll have no trouble finding your way around a track at night...very impressive!

John...I am lost for words!

Regards,

John.

LOL!

Further to these lamps. I have drawn the manufacturers plates in 3D. These have been printed in wax in New Zealand and investment cast in silicon bronze. The detail level was at the edge of the printing capability. I have made a jig to bend the plates to fit the lamp body. Pictures hopefully in a minute.

Jig as milled in dividing head, the spindle is actually vertical

Microscope on Dore Westbury. Drilling spindle is a Proxxon flexible drive held in a drill chuck in a modified tool post holder. You can just about see the plate I was drilling, taped to a bit of card.

All wax printing/casting was done by Michael Jack of Stanier Engineering in Auckland. I would not hesitate to recommend this thoroughly nice guy to fellow modellers. Usual disclaimer - only a very satisfied customer!
