Going to the store in a moment: What tool does reaming require?
Hello.
I am going to the store in a moment. What is the name of the tool that you use to wide the end of a copper tube like the following for brazing?:
Reamed tube.png
I need to know so I can at least check the price in the store, if it is a very cheap tool, i'll get it. Is it a necessary tool?
Sorry, I thought it was reaming for a second. Not reaming, just widening the end of the tube so I can fit another tube of the same size into it snugly. Not the flaring tool used for compression fittings.Last edited by Kompulsa; 05-11-2011 at 11:52 AM.

good morning kompulsa- now hopefully u have a turbo torch,and a swaging kit, to carry out ur lil hobby, dont forget the nitrogen gauge and nitrogen, gauge manifold,vac pump,torr gauge and charging scales too,and also leak spray your gonna have to recycle ur copper collection to fund this-get a fire extinguisher too!

Re: Going to the store in a moment: What tool does reaming require?
Tut tut Mike
Soliciting for reps is frowned upon.And surely changing pots at 8 is ok.
But you scratch my back ,and all that .haha

Re: Going to the store in a moment: What tool does reaming require?
I got the torch at the store yesterday and am improving already. I didn't burn up the tube nearly as much this time, and did the braze in less than 30 seconds this time, I will keep trying to minimize burning.
By pot, do you mean compressor?Visit http://www.kompulsa.com/ for technology news, reviews, and more. Twitter: Kompulsa.

Re: Going to the store in a moment: What tool does reaming require?
yes the term pot is referring to the compressor- try heat shield mats or koolgel to reduce burning,otherwise reduce the flame on your new toy

Re: Going to the store in a moment: What tool does reaming require?
Ok, I don't have nitrogen. Can I circulate R22 through it instead to prevent the corrosion then?

Re: Going to the store in a moment: What tool does reaming require?
No absolutely not burning R22 produces a nasty by product akin to phosgene .
Good for clearing the sinus and not much else.
Any agent used for purging must be inert.

I strongly suggest you undertake some formal training in these disciplines as this forum is not a school.
Some of these questions are ridiculous ,and a serious injury is only around the corner.
Do yourself a favour and get some training.

Re: Going to the store in a moment: What tool does reaming require?
Hi Kompulsa
You'd be best to pressure with oxygen and get a nice flo of it for when your brazing, it would help a lot of new comers if you could video this and arrange someone to upload it here, in your absence

and O2 might be cheaper than nitrogen, not sure
Just make sure your insurance is up to date

Re: Going to the store in a moment: What tool does reaming require?
Hi Kompulsa,
Some would call it a joke I suppose...
Nitrogen is the standard purging gas for brazing. Probably find other gases cost more but any inert gas would do I suppose.

Re: Going to the store in a moment: What tool does reaming require?
What I am seeing here is that purging during brazing is to displace oxygen which causes oxidation of the joint, which is what I thought: http://webcache.googleusercontent.com/search?q=cache:_bBM4iK-QG0J:www.copper.org/applications/plumbing/techref/cth/cth_7brzjts_purge.html+copper+purging+gas&cd=1&hl=en&ct=clnk&gl=jm
That is the Google cache of Copper.org's page, the link is now broken so you can only see that cache page.
There is no oxygen in R22, so why can't it work instead of nitrogen? I have R22 already.
http://en.wikipedia.org/wiki/Chlorodifluoromethane
I forgot to add that this is a temporary project, I am going to break it off within the next year anyway, so the joint does not need to last long, if that is the only concern...Last edited by Kompulsa; 07-11-2011 at 12:11 PM.

Re: Going to the store in a moment: What tool does reaming require?
Yeah, try r22, just try it.
Come back with the findings as none of us have ever brazed with a bit of R22 left in the system before, so we don't really know.

Re: Going to the store in a moment: What tool does reaming require?
If you have to ask why you cant braze with R22 you shouldnt be brazing until you get some training..... as has already been suggested!

Re: Going to the store in a moment: What tool does reaming require?
Good point Stu, might have created a monster!
An old supervisor of mine did some brazing on a Foster cabinet which used R600a. He steamed in (untrained I think) let the gas go, lit up the torch and promptly lost his eyebrows.
Shouldn't laugh but can't help it, even now.

Re: Going to the store in a moment: What tool does reaming require?
Kompulsa, do you really want to use an ozone depleting gas as a purge gas? It won't end well. Find an old fridgie and cry poverty. He may help you more than you could imagine.
