Ceeway (http://www.ceeway.com/Framesaver.htm) sells internationally (at least to CAN). The Ni-silver is the Sif bronze no2 I think.

Have you tried local welding shops? Certainly they must carry brazing stuff. That's where I get the low fuming bronze, flux, etc. For silver solder (45, 56%, etc) eBay works sometimes.

I thought Sif was a brand. I've used quite a bit of nickel silver. We used it for brake/chainstay bridges and dropouts. I like low fuming bronze better now. One aspect of nickel silver is that you may be allergic or develop an allergy to it.

"" nickel silver is that you may be allergic or develop an allergy to it "" = whats this?

Some people are sensitive to nickel: http://www.aocd.org/skin/dermatologic_diseases/nickel_allergy.html

Usually this is a dermatologic reaction from jewelry, but brazing could vaporize nickel that could be inhaled and cause a respiratory reaction.

That said, I brazed dropouts using nickel-silver for years at Trek and never had a problem.

I had very mild resperatory symptoms the whole time I was there, don't know if it was the nickel or just the brazing fumes in general. I remember it positively, so bought some just to refresh my memory. I realized that I prefer to use LFB. It is nice to have some around when I need to braze stainless and don't want to waste silver.

hmmm , its ok i think, my skin is always senitive to almost everything .... (i get rashes even from using baby lotion ! ) but i used to using alcohol swaps swapping my skin, funny right ... :D

will worry the allergic if i can get some rods and braze (thanks guys for the headup) ... meanwhile still searching high and low for a few pieces (low buget) :(

apparently, i think i need to change my rear drop- outs as it does not comes with a derailer attachment hole :( (cheap bike) and learn the process while making myself a 'table' ......
