I wondered how easy is it to form a pouring lip in an aluminium pot (and how)?... Eg in a Trangia 25 inner UL saucepan: to improve pouring into small flasks (inspired by the MSR titan 'kettle' which is really a mug/pot with a pouring lip...?)
Interesting question! I was musing on this the other day with a different pot - the Svea cup is a little tricky - the user has to be just slightly aggressive with the pour, though not too aggressive, or there will be spillage. A minor annoyance for sure. Making early morning Tea or Coffee is a series of steps or sort of competency test, you see.
I've wondered this, too. I actually find the inner saucepan pours ok if done very slowly. the frying pan is more useful for catching water from a source with many slow drips, but has much worse pouring properties (annoying to lose the product, because those drips come so slowly...). pouring accuracy can be improved by putting a spoon handle against the lip, which discourages the water from curving backwards over the rolled edge of the pan. but that ties up two hands, with none left for the bottle there's lots of guidance on spout design for potters on YT, etc: the key thing seems to be to make the edge of the lip sharp, which would mean flattening the aluminium rolled edge. I'm minded to get a battered old Trangia pan (anyone in the UK wants to sell me one, lmk) and bash a few lips in the edge to see what works. I'm guessing something like a lead worker's setting-in stick would be useful: www roofingmerchant co uk/tools
Shape a piece of wood as a female mold so to speak and use the end of a ball pean hammer to form the pot to the mold . To avoid problems with chipping the hammer us a dead blow or plastic mallet to strike the hammer face ,The hammer itself is actually the punch in this case not a hammer . Good luck
Use the ball pean hammer as the forming device / punch , the round end should form the pot easily . You will be striking the “Punch” with another hammer / mallet . One good heavy blow will more than likely do the job displacing the metal into the form cut into the wood .Note a 6 oz pean hammer has about a 5/8 inch ball . Hope this clarifies . Cheers
