@podbros You raise a very good point. Once upon a time there was Hawker Siddeley in Hatfield only about 3 miles from me. They made Tridents and...
@Fireexit1 yes thanks. I have tried tempering a second razor blade and it's better but I suspect it's still basically the wrong steel. Also it's...
I have been looking to obtain a small quantity of the above. Maybe something like a 100 x 100mm sheet though even smaller would still be useful....
It's not an easy measurement to make.. here is my idea about it. It would need at least vernier calipers or even better some sort of micrometer....
I thought of another. I wish I could find a picture to support this - it is true. In the 1980s there was a scanning radio receiver on the market...
Isn't this all down to tolerances in the machining? If the back drill process goes too deep it leaves the dome very thin. Easy to make the jet...
I have a beautiful engraved Zippo saying 1997 Hong Kong Day of Retrun. When I noticed I started back to the seller thinking knock off!! I noted...
I think that's different. C2H6O Ethanol - main constituent of Meths and probably Bio-Ethanol. CH3CHOHCH3 - Isopropyl Alchohol.
Isn't rubbing alchohol Isopropyl alchohol? I'm pretty sure that is what I have here. I seem to remember that it burns with a yellow flame....
@Anthony wow- what a picture. Congratulations on your cross sectioning skills.
Good progress. Does the air pressure leak out of the tank even when you have screwed the pump rod in? Usually the NRV leaking a bit during...
I suspect this might have a similar fuel pickup issue to the 533 stove. In the exploded diagram they don't show a rubber washer that goes hard and...
Don't fancy being sent to work the pricker on that FL6 locomotive headlight...
Is there a difference between vapourised fuel and atomised fuel (spray). Can that be why the preheater might use more? Absolutely right that...
Thanks for the ideas. I suppose it could be just marking. Actually what I want is the needle since I already have a new nipple marked 350. It has...
Does anyone know why the base camp lists different part numbers for 350 and 250cp nozzles if the lamp is a Hipolito vs Petromax? For 500CP they...
I have a Hipolito H502 which is stamped on the base 0858. As I read the foregoing that would suggest it is week 08 1985. Am I right? Given...
@isfuzzy - putting out the challenges!! :)
Thanks @Mackburner. I knew I had seen an earlier post from you about it. I went looking in the ref library but I could not find it. It is a very...
I think once you have done this modification the jet will last almost forever. Afterwards the pricker wire and the jet have about the same...
