Repairing old bulbs
FRANCO.M:
Hi collectors.
I think that adam2's comment is very true !
Light bulbs repair is more difficult than build a new .
I'm principally a ww1's radio collector and i'm tto much fascinated fron first electronic tubes.
For my enjoy ( and scientific curiosity ) after 3 years of work i've built an radio tube factory.
In my laboratory i bend, weld and blow the glass; i've an air cooled diffusion oil pump and many other machines.
The problems to repair an old light bulb are too much.
Is very easy that the glass crack during the cutting to open the bulb and more easy when welding to close too.
Another problem is that you cannot weld two different quality of glass, so when you weld the air estractor you are't sure of a perfect join.
The vacuum pump is the ultimate of your problems.
I've began repair 7 bulbs ( not precious double loop carbon filament about 1900 ) and i've broken all !
I think that for learn to repair ( well ) an antique light bulb i must destroy 1000 bulbs, that is inconcepible.
So i've decided to abandoned this project.
If you are curious to watch my " secret lab " go on Youtube and digit: Le Valvole: Costruzione hobbistica di un triodo anni '20 .
