Should you give more informations about torch :) Cost of torch, oxygen bottle etc.
I'm planning to buy torch like you, but firstly I must buy oxygene bottle, which is a little
expensive for me..
Grotesque is always for me a negative thing
oxy bottle is 10Liter and cost me about 150 euro. I bought everything seperate and don't know all the costs anymore.
what don't you like about my evap?
You can rent a 10l bottle for 30€ for a year here, if the bottle is empty you can change it for a full bottle with any gas you want (only have to pay the gas price). So renting is an opinion too.Quote:

Unknown_road, I'm not saying about your evaporator. I'm saying about photo. Only
this photo makes me grotesque feelings, not evaporator :)
Looks good, but all that extra copper will make it pretty heavy. On the other hand the extra mass may enable it to hold its own against a higher load.
I love this thread. I wish it had the pics from the evap gallery thread from www.phase-change.com
So many beautiful and innovative evaps!
i have seen yesterday a "trapano a colonna" donno english :(, like the one that you use shamino) for 49€....i think i will buy it....49€ and i can make all the evaps i need :D

what you use to drill lots of holes in a copper block to make an evap?? :toast:
when it comes to torches ppl really underestimate the map gas torch.
that is really all you need, and maybe gas camping oven. i do evaps on low map gas setting.
i would hate to have to pay for oxygen the way i braze.
map gas last foreva.
you would be suprised the ampunt of ppl that use it.
Today I went to the shop to get more brazing ros and ended upp with 1kg of 2% PhosCo and this:
http://www.primus.fi/www/popupcard.php?id=221
It uses a gas mixture of Propane Butane Propene and Acetone so it is more powerfull than the regular propane+butane torches. Very handy and brazed 5/8 tubes with ease:) I'm pretty sure it is equalent to MAPP in preformance. The set cost me 130 wich is kinda much byut not if you compare it to oxy/acetylene setup costing 1500€

The torch I posted above works like a charm and you can propably find one in italy for a less than what I paid for. Just make sure it has the ultra gas botle and not the power gas one. the powergas is regular propane+butane one and the torch tip is smaler and less powerfull than in this torch. you can find it either under Primus or Sievert brand name:)
i found mapp bottles @3€, the prblem is the torch!
I have more torches here. I have a oxy/propane set (Gloor lilliput) of very high quality, I use this one for brazing. Mainly because it is much quicker than a non-oxy flame and smaller (so easier to handle)
I have 10 euro hand propane torch (with expendable propane containers). I bought it for soft soldering, but now i use it for extra heating when brazing evaps (to safe the much more expensive oxygen).
And a swirl flame propane torch. This one has a 2000c flame with a 21mm diameter. This is more than enough to braze pipes together, but i use my oxy/propane torch for this. Now this torch is used as pre-heater and extra heat sorce when brazing very large things.
I can get a oxy refill for about 20 euro (10Liter) so that not to bad. The price of buying an oxy cilinder is high but once you have one your in bussiness :p:Quote:

One of my evaps is brazed like this and the other is still unbrazed:

Do you think it's like this?
I know that it's better to have the cap line in the center, but with this design, that's the way I think it's mean to be used...
lol no
see the little hole in the middle ?
it should go through there (from within the suction line)
