 So i have a trangia burner that the screw cap is stuck, i think it was screwed on to tight while the burner was warm so causing a vacum? Anyway apart from using a vice-grip (which i don't have) or stabing the lid with a knife, can anyone think of a way to get the lid off? cheers

 freezer! metal shrinks when cold,expands when hot! Just and idea.
|
|
 Try unscrewing it whilst wearing rubber gloves (so many jokes there).
|
|
 I solved it by putting burner in freezer. Then I put the burner in a vice and used adjustable grips to get the lid off. The only casualty was the rubber sealing ring which had to be replaced.

@ The Didster, was thinking about freezing it but wasn't sure if that was just all in my head that if metal shrinks wont the cap shrink onto the threads more?cheers! @ Lester, don't really want a hole in it, but cheers! @ Warhippo, not sure if i have any of them either, but think i have some rubber gloves. cheers! @ moel hebog, don't have a vice or vice-grips, but cheers anyhows!

 Rubber gloves are always a good start for stuck lids of any sort, simply by improving your grip. If you're going for the thermal route, then I'd stick the lot on the freezer, then, when cold, take it out, heat the cap and quickly try to open it with the gloves (leather gloves might be good in this case, giving grip even if hot or damp (condensation)). If it really is due to a partial vacuum, then heating the lot will be the best bet, increasing the pressure inside to something like atmospheric. How long has the lid been on? Was there meths in it when you put the lid on? If it's been a long time, and there was meths in it, it could simply be corrosion. In which case, some WD-40 and brute force with the gloves... Actually, a lubricant might work even with the pressure problem, as it might allow the rubber to slide over the brass.

 This will sound a bit weird but try and tighten it first. Sometimes it works. Failing that, a dry cloth. Just build up the pressure without gripping too hard... ...said the bishop to the actress.

thanks to everyone!
I stuck it in the freezer for a few hours then managed to get it off with a pair of rubber gloves, so cheers again all! (maybe next time i wont be in such a hurry to get a move on  )

Or if all else failing try asking the wife to have a go  . .

.jpg) What did you need the lid for anyway.?Just another item
to carry and loose.Cheers.
|
|
well it was only a day walk so i just poured x amount into the burner to do for a few brew ups, on the last one i must have been a bit over zealous! No fear of losing it as its either screwed on, or as soon as its unscrewed i put it away in the bag that i carry the lot in. So yeah it all adds up to extra weight, but it kinda works for me for what i want to do with it & how not to lose anything.

I remember taking a group of 'city folk' on a camping trip, gave them 6 Trangias and all the instruction they needed to use them but despite this, they all put the lids straight onto the hot burners after use - glued half a dozen lids on. BAH!
I wasn't there where they did it but I was certainly there having to sort the mess out.
Glad your burner's sorted : ) I'm the same as you Padstowe - the lid is more useful than the extra weight is a problem to carry.
|
|
Padstowe,like you say, you unscrew the lid and put it in the bag with the other bits. My question was what do you need the lid for.? When in use the lid is off and serving no purpose anyway.Cheers.
|
|
 Waldo, you do realise you can fill the burner and put the lid on? The Meths won't leak out of the burner.
You make a brew, snuff out the flame (with meths remaining in the burner) and put the lid back on again... Then you can use the remaining meths later.
|
|
Waldo, i did say that i had put the meths in the burner to make a few brew ups, so if i hadn't of used the lid then it would have emptied out all over the bag. I know i could have taken a small bottle, but my choice was to take the burner & cap. Hope that has cleared it up for you. cheers
|
|
Maybe smear a bit of alcohol gel/grease/oil around the inside of the lid will help in future. Might actually do that to mine - I've had trouble myself at times.
|
|
Padstowe, thanks for the explanation,you use a different system to me. For instance cos. I,m usually out for multi days I carry my meths. in a seperate container anyway ,and only top up with sufficent for a brew etc.. I only only take the simmer cap with me, and often leave the burner on low until it burns out.This helps to "air"the tent a bit too. How we do these things is often what suites us best. Cheers.

I with you on multi days waldo, but as you say it is down to what suits us, & the lid suits me fine for day walks. I never take it if am out for longer & have a bottle with me. cheers P.s i may go back to a penny stove for day walks, but then i have to take a bottle. I guess its down to what we have & how we use them?

MrSworld, yes I do realise the cap can be screwed on to contain the remaining meths. Also realise the meths remaining is very hot and although the seal is butyl rubber in no way is it good practice to replace the screw top until it's at least cool. During that" cooling period "the brass burner ,also very hot, is very nicely evaporating what little meths. remains in the burner.Cheers.
|
|
So just use the lid to snuff out the flame, remove, and wait until the burner is cool. Then put the lid back on.
It's not rocket science Waldo....
