Members guitar Dan Posted February 9, 2012 Members Share Posted February 9, 2012 Hi Folks this is just a long shot. when i was at school in the 70,s we used to braze with propane gas and compressed air,i would like to rig up a little Brazing hearth in my shed but i carnt find a brazing tourch that will work on a gas / comp air mix. so my question to our world wide diy folks is.... do you braze with compressed air & gas and if so were did you buy the tourch from ? many thanks Steve in sunny / cold Almeria Spain Link to comment Share on other sites More sharing options...
Members tedmich Posted February 9, 2012 Members Share Posted February 9, 2012 glass workers use these all the time, an old chem lab type surplus will be cheap, newer ones a little less so. http://www.littonengr.com/National_Hand_Torches.cfm I believe any std gas + Ox torch can work with air it just gets blended at a higher ratio (being only 20% O2)http://www.harborfreight.com/micro-soldering-and-welding-torch-kit-95671.html Link to comment Share on other sites More sharing options...

Anything else and you're asking for trouble. The kind of trouble that can lead to you never posting anywhere again.I may be a cheap b@$t@*d, but I don't like hurting myself.

Members cx04332 Posted February 9, 2012 Members Share Posted February 9, 2012 If you are working with small items, try a Meco midget. There are 3-4 tips with it that allow you to work on larger items also. http://www.tinmantech.com/html/meco_midget_torch.php good tools are good inverstments Link to comment Share on other sites More sharing options...
Members fatusstratus Posted February 10, 2012 Members Share Posted February 10, 2012 Dan; you were probably using oxy (not just aire, you might remember the threads being left hand on the threads of the second bottle) Bernzomatic and worthington still make those sorts of kits, but the propane is usually replaced by MAPP (well, mapp-like blends, I think real MAPP is discontinued) Link to comment Share on other sites More sharing options...
Members guitar Dan Posted February 10, 2012 Author Members Share Posted February 10, 2012 It was deffinatly compressed air,because we used to turn the comp on first ,i can get oxy & welding gases here no problem its just that we have to rent the bottles at $300 a year plus the gas charge ,so i just need somthing to do little jobs that are to thin to weld with mig. just out of intrest ,we use beer co2 gas here for mig welding as its cheap and works great on car bodys and thin steel. thanks for all the feed back folks ,im diy ,ing steel framed guitar & speaker bedroom cupboards at the mo with the pub gas welder Link to comment Share on other sites More sharing options...
Members cx04332 Posted February 10, 2012 Members Share Posted February 10, 2012 Check with other welding shops for rental rates. I pay about $60 a year for one tank. You might be able to find used tanks for cheap. Again check with the welding shops. If you have space, go with the large tanks. Little tanks always need refills in the middle of projects.

A trip to Cheap Chinese Tools (aka Harbor Freight) might be in order Link to comment Share on other sites More sharing options...
