Discussion in '118' started by rollschmidts, Jan 25, 2011.
Hi all together ,here you see my Radius 118 .Its a fine latern,i love it.
ich würde sie auch lieben.
Ich würde sie dir auch abnehmen
Ah! Das ist ein sehr schönes laterne, und leider eine das ich vermisse.
Es sollte eigentlich in Schweden bleibt, so sie können es zu mir schicken
Hallo . ja wir können mit der schönen Tischlampe von Deinem Avantar tauschen
OK! Denn Ich denke, Sie werden Ihr Radius halten.
Ein Primus kann nie mit einem Radius ersetzt werden.
Considering it's a Radius 118, it must be getting close.
True, true... A 118 is always a 118.
I really like the cleaning needle mechanism on those. I have no idea if it works well, but it has a pleasing look to me with that lever.
To bad that the Revolto misses a few parts.
That was a nice one!
Isn't the top unusual as well, green can't be most common colour Radius used.
I just assumed that it was a replacement from something else, but looking closer it does seem to have the correct Radius shape. Maybe Roland knows if it is original.
It works well on my 118. It has to be set right so needs more care when re assembling the lamp but it is simple and positive in action. Actually an old idea. You see this done on some Britsh lamps in the mid 1920s. The BP Cleary has a lever operated screw like that. ::Neil::
can you take a picture of its gauge. If only you can open the gauge and tell me if it is the mercury gauge or the spiral metal gauge.
I want to know that for some reason.
ah we have not seen these questions for a long time now.
So what do you think is the magic potion in these old pressure gauges. Tell us the reason and we may be able to help.
Hoooray! Here they are again - how I missed the hunters of the miracle manometer.
I can remember these folks walking in to the shop of Stuga-Cabana and examining carefully each single lantern until I asked them to leave and not to come back. I can't believe this nonsense is still going on. Others purchased lanterns and send them back complaining, the pressure gauge was "wrong". @Mohammad Yaseen, sorry for being impolite but please go away, do not come back and tell your customer to stop that incredible junk.
I think no one need to be impolite because all we can be so but this is not helpfull for us. We need to cooprate not to heat each other. Why some people are so angry here !?. Ok yes I want to know about this fact and if it was a fact or just a rumor or marketing hook. There is no majic or meracle. Some people say that there was some precios isotope of mercury that was used in some of the models as mercury is responsive for heat change. I want to know about this as science researcher. Hi Erik I am physics theorist that made great researches in theortical physics, unconventinal science reseaecher. Not a fool as you may thing. this material was really used in some if the old devices and some frirnd was show me some sample of it. Please be more flexible regarding scintifical facts.
I wish if someone can help me make sure that this metarial was really used in this devices.
Well, all I can say is that some years ago I got an NDT engineer to take X-ray images of a Vapalux manometer - which proved to be a Bourdon tube* as it happened (not that someone here believed even X-ray images - no names; no pack drill ). Perhaps that's a way forward here, though...
*admin edit - as requested.
This makes no sense to me. Mercury like most metals expands with heat which is why it is used in thermometers but these gauges are measuring pressure and in general metals don't compress well. I know mercury at room temperature is a liquid but I still doubt it responds to pressure. It was indeed used in early pressure gauges but only as a column driven by air pressure. Petromax gauges were patented in the 1930s when there was much experience in engineering with Bourdon tube pressure gauges and can hardly beliveve Petromax opted to used mercury in a Bourdon tube when air does the job perfectly well. Bi-Metal makes no sense either as that also responds to heat not pressure. I am pretty sure all Petromax gauges will be Bourdon tubes. ::Neil::
Nah, it makes no sense to me either, Neil - and I wrote it! What I meant to say was that the Vapalux pressure gauge was shown to have a Bourdon tube inside. Hopefully Christer will edit my earlier post and say what the edit was for.
Too much alcohol, too few hours of sleep and too many miles on the clock - pick any two from three...
Neil, David, these people are immune to feedback, believe it. They want to hunt down a source of "red mercury" ore some other fantastic material. Words just wasted, for 10 or more years.
Erik, I wasn't referring to anything other than the obvious error I made in my post #15 above. Hopefully that'll clear things up...
