let ther be light
« on: April 01, 2018, 04:56:14 PM »
hi all I got a carbide lamp off john so I have bin on with it in all its ok just needs my loving touch  a lot of the rivets have cum out I was surprised that they where aluminium and not copper or brass any way I removed the front lenses cover as the rivets on the hinge had broken off the lenses it self is broken I will get a new one but to stop it all falling to bits when I remove the retaining ring I went over the broken parts with thick super glue to keep it in one bit then I removed the brackets and wind Gard of  the lamp bowl  then gave them a good buff up right pics

Bob

It looks like a cycle lamp as it has a bike bracket

'Lead kindly light!'

hi yep its a cycle lamp any way I re riveted the wind Gard and bracket back on desolderd the base of the water container so I can remove sum dents and  when I make the tank filling  top it can be soldered in place am thinking of strengthening up the bottom cap where the gas burner goes threw I removed the spring loaded mounting bracket and put them in a gar with citric acid to remove the rust then gave them a cote of rust inhibitor then panted them black right pics

ok all its Neely finish I resolderd  the bottom of the water tank back on and the burner tube then I made a plate out of brass to go on the bottom just to sit inside the space where the burner tube sits don't no if tis is right but looking at watt holds the felt filter I think there shod be something like that there any way fitted the filter then filled the tank with soapy water  then cheeked for  leeks there was non and cheeked the valve to see that it let the water run out all ok I made a rubber seal for the bottom tank that holds the carbide and yep it works pics

Bob,

Have you a rough idea as to the dimension of the spring, if so I'll have a rummage in shed.

Great job on that! Where can you get the carbide for them and how long does a piece last?

Hi Bob and All,
Great work on the lamp
If I may make an observation?
All the carbide lamps I have seen have a glass mirror / reflector behind the burner
I cannot see one in yours?
They are very often cracked or broken though  :bang:

Many years ago when I was much fitter (and much slimmer!) I went down Swildon's Hole in the Mendip Hills.

Once down past the 40 foot and 20 foot pots, the cave levels out a bit.  I remember that, every so often, one would pass a small heap of wet lime where a previous caver had emptied his (or her) acetylene helmet lamp and refilled the carbide container.

I remember that the trick was to cup one's hand over the reflector to allow sufficient acetylene to accumulate before operating the spark igniter.   
Best regards,

Pete W.

It brings back memories.   

I was brought up in a BC mining town where miner's carbide cap lamps were common.  In the '40's there was a conversion to electric lamps which liberated hundreds of carbide lamps that became toys for the more youthful element.  In these days carbide lamps were blamed for many fences and garages burning to the ground and even a house or two but the biggest problem was that when the flame was extended it produced a very dark black soot on any object it touched and for a few years almost every window and painted area in town was covered with rude graffiti written in carbide soot.

As Pete.W says the starting technique was to turn on the water a bit and cup your  hand over the reflector for a few seconds before drawing your hand off over the flint-wheel.  My understanding was that if the flame was moderated a single filling would easily last 10 hours although the water might have to be topped up.

There are still many carbide cap-lamps around although carbide IS hard to get.   Here's one that hangs on a nail in my shed...it's a typical "Justrite" miners cap lamp.


Of course I never took part in any malicious activity but I did learn that carbide and water makes brand-new blue-jeans turn white and crumble away in minutes.

Good job, thanks for the memories KRV3000, yours is very pretty.
