Thank you Dan. I am away at the moment so I can't post any measurements for comparison with your readings but I can say that, from memory, your...
Yes David, the background count is important and so it would only be meaningful to state the background count and then the absolute counts or to...
I see what you mean David. MR/HR is milliroentgens per hour, mR/hr is millirems per hour.....
Very interesting. My friend has a Geiger Counter and we have tested a variety of different mantles. He is an electronics enthusiast and has...
I presume your lamp is a Petromax from your description? You can turn the lamp off by turning the wheel but the risk is that the needle then sits...
I've also found Peerless 24A mantles excellent in Petromax 829s. They are a good size, shape very well and the fine weave contains the flame...
Completely agree with you Stu -it's up to the individual's judgement. In clock forums there are endless, often heated, arguments about this. The...
Interesting Steve. My tank was also low when this happened. I suspect grot in the fuel. This could be especially problematic with an Anchor...
I would check that the burner is clean. You can unscrew the air buttons to get the whole burner/mixing dome assembly out and clean it. When you...
Stress cracking in brass is also well recognised in brass clock parts (another interest of mine). It happens when the zinc is selectively removed...
From left to right: All operating on paraffin at 2.5 Bar. 1) 829B Bundeswehr made 1969. Fitted with paraffin. preston coil vapouriser. Hybrid...
Yes. Obviously one shouldn't leave lamps unattended for long periods but this happens so quickly that it means I feel uneasy walking away from the...
I found some more information on diesel in Petromax lanterns. Apparently Petromax did say diesel could be used but only in emergencies (this was...
You are absolutely right. I was quite scared! It has never happened before but I won't trust this lamp. I think I will rinse out the tank tomorrow...
Thank you Christer. I had the lamp in the garden and I was only a short distance away but by the time I had realised what was going on the j-tube...
Whilst using a Petromax 829B this evening an unusual thing happened. The lamp had been lit for about half an hour and was at a pressure of 2.5...
I like the Peerless 24A the most. Not just because they are so bright but because they have a very fine weave that contains the flame very well...
I thought I would do a test of 3 different mantles on 3 as near as possible identical lamps. All three lamps are Petromax 500 HK. Two are...
I just received some Peerless 24A and Peerless 1111 mantles from the USA. It took a while because there was a customs charge and an £8 handling...
Thank you for the information Stephan. I learnt something else about these hoods from the Pelam forum. Some of the early ones, like mine, are...
