My First Crack at a single stage

[Dementor]

Well after recieving everything that I needed from runmc and chilly, its time to work on my first ever anything related to cooling, specifically, my first single stage :) Here are a few pics attached below. Basically, I dont want this thread to only be MY worklog, but also as a thread, possibly even a sticky if it gets good enough, on absolutely everything and anything anyone would need to get themselves started. For now, ill just post pictures of all the necessities, and then update it slowly as I go along for the ride. :woot:

More to come soon. Any tips would be nice :)

Seems condensor and fan are a bit fubared...

Very nice tools,i'm crazy searching for a new torch and a vacuum pump.
What gas do you have in the bottle?
Tip 1 ) You should be able to braze most of your joints with just mapp without oxigen,this kind of bottle lasts very little and is expensive,a bigger bottle with oxi regulator would be a good investment.
brazing copper/copper use phosporus or 15% silver,no flux needed. copper/brass you can use 15% silver with white flux needed.copper/ss you need at least 45% silver rods and black flux.
Do you have nitrogen or co2 to purge/leak test your system?That would be good too

[Dementor]

The gas is the blue bottle is one of chilly1's mixes, 65% Iceon and 35% R507 I believe. The vacuum pump itself was purchased from chilly aswell.
As far as the nitrogen or co2, I dont have those.

Seems condensor and fan are a bit fubared...

The condensor does have some damages to it, but the fan is just cosmetic damage. Damn USPS! Took forever to get here and they break crap.

[GuGaCoSa]

Please,if can,send me the price you paid on the vacuum pump and how much cfm it are.

[l3ored]

would it be allright to post how much you spent?

[Dementor]

$150 for the single stage 1.5 cfm vacuum pump.
Hrm... For everything? Well I spent around $180 at runmc's shop, $275 from chilly, and around $150 locally and a few other things... I would say around $700 for everything included in that picture :)

[l3ored]

owch, i was under the impression that phase change could be done cheaper

[Dementor]

A phase itself is alot cheaper. You just need to buy all the tools if you getting started. Which puts a hefty price on it.

[jinu117]

And dementor managed to play cheaper with getting gas from Chilly1 :) Try getting gas locally or what not... I don't see recovery tank and recovery machine which will add substantial cost to the setup :) Looks like you are really getting ready dementor. BTW, if you got the torch from homedepot, it might save you in long run to return it and getting actual acetylene & oxygen kit... I really didn't like the thing and it's sitting there doing nothing really (anyone need one?)

[n00b 0f l337]

*I could use an extra torch*
The homedepot one works just fine.

[Dementor]

Yea, I bought this torch from Sears, which is basically the same as a home depot for $50. Isnt a acetylene & oxygen torch costly? BTW, I cant return this one because Ive had it for awhile.. Probaly a month and I dont even have th receipt :-p

[jinu117]

*I could use an extra torch*
The homedepot one works just fine.

Wow, some people have the finess to adjust it well I guess :) It took me too long to adjust each time correctly and eventually used too many gases (I need to find out what is the RIGHT way to dispose this little cans.... 7 in total)
As for extra torch lol, let's see if anyone needs one first :) Even MC and R tank is cost effective for me than this run down to homedepot and grab bunch of tanks run hehe.... :P I will probably get B tank and RR tank soon in next few days as I don't want to drive down every week for gases.

[the_new_guy]

cool Dementor you have got almost every thing now
how long have you been collecting?

[Dementor]

Well im new at this, but when i opened the MAPP and light it, and then applied oxygen, nothing really changed. Is there susposed to be a big change in the flame? I knwo oxygen is being applied, but nothing about the flame changed :-p

[Sneil]

you probably dont have any o2 in that flame. it should change drastically getting way smaller and turn into a bright whitish blue color. it should hiss loud too. i have a canadian tire oxy mapp torch and the regulator on the o2 is crap. i have to turn it like 3-5 times before anything comes out then adjust it ever so slowly once the o2 finally does start commin out. just keep turning the regulator very slowly until the flame changes, may take a while if you have the same one as me. be as quick as possible when u braze (with quality brazed joints) otherwise the tiny o2 bottles will be empty in no time. it will take practice and you may waste some o2, but dont get discouraged

Edit: actually looking at the picture that is the torch i have. your big yellow flame should turn to a very small .5cm loud blue flame. that'll heat things up nice and fast. once the copper is red hot, pull the flame back about 1-2 inches over the solder rod and it'll flow very nicely. adjusting the distance of the flame when the copper is hot enough and as your applying solder is key. experiment

[jinu117]

Regulator in O2 is crap with no fine adjustment (reason why I said finesse above). That is the exact reason why I don't like. Another thing is regulator on mapp fluctuates over time which makes it harder to get good flame going. But seems like at least few people are good with it... I gave up after burning through 7 cans total myself.

[Dementor]

7 Cans. Ouch... Now I wish I had someone to do this whole thing in NY with, cuz im really lost. Dont have spare parts to be putting everything together in the wrong place. This is, afterall, my first try.

[RussC]

It can be a little "overwhelming" to begin with. But, it's not that hard. But you will burn up some of those red cans, to be sure. Ive been through 6, so look forward to that. The valves are touchy, but not so hard you can't get a good hot flame. I've done well with that torch.

Just go slow, and ask questions.

[jinu117]

Oh... and buy 3 times more oxygen than mapp. Ratio of consumption was roughly 3:1 :P Damn these little things do get expensive over time quickly vs acetylene oxy setup...
