Hi Jeff, Good point, fumes can be a health hazard for sure. Since I seldom braze - I normally turn on a large floor mounted fan behind a wind shield (plywood) with my work below the wind area and my face above it. So I get a pretty steady and strong breeze and it seems to keep most of the fumes below my air intake level. I also wear a nose/mouth guard - but mainly to keep particulates out of the lungs. Needless to say, if I did it frequently (so far about twice in four years) as in fabricating inlets for sale, I would take stronger precautions. But, here is the URL for the MSD on the brazing rod, it does not appear to me to be particularly nasty, but then I am really not that well versed on what some of these MSD descriptions really mean. So if you would take a look and give us all your assessment, it would do us all a service. http://www.aluminumrepair.com/msds_2000.asp Thanks Ed Ed Anderson Rv-6A N494BW Rotary Powered Matthews, NC eanderson@carolina.rr.com http://www.andersonee.com http://www.dmack.net/mazda/index.html http://www.flyrotary.com/ http://members.cox.net/rogersda/rotary/configs.htm#N494BW http://www.rotaryaviation.com/Rotorhead%20Truth.htm -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Jeff Whaley Sent: Tuesday, April 14, 2009 10:29 AM To: Rotary motors in aircraft Subject: [FlyRotary] Re: Brazing was [FlyRotary] Re: Beading a tube Hi Ed, what personal precautions do you take when brazing aluminum? What safety data is provided with the brazing rod? I believe the fumes, mostly from the flux, are extremely harmful to your lungs ... lungs cannot be repaired.

But, I have stacks or aluminum brazing rods that I could never get them to do more than sizzle around like a drop of water in a hot skillet {:>). The HTS-2000 was the first one I had any success with and did not require special prep of the work area. I realize that other folks must have had success with the other brands, but I did not. I mean enough folks must have continued to buy the products to keep them in business - but the HTS-2000 just flowed great and just a brief scrub with a stainless steel brush was enough to get adherence. I use it to braze my aluminum intake manifold (since I don't weld) and am still flying with it and no problems thus far.
