Chainsaw Repair

I use silver solder for all my muffler mods. far easier to use than bronze as you don't need to excessively heat the crap out of the parts. most times it's stronger than bronze. adheres better as well.
lots of talk about 'puddle control'. it's a non-issue somebody is making out to be an issue. the silver (or in other cases bronze) will follow the crack, seam, hole, connection, etc. with no help if the area is cleaned and fluxed properly.
the only issue I have doing it this way is cost. the price of silver solder has been steadily creeping up. it's still cheaper than brazing if you factor in the cost of the oxy-acetylene gasses.

I use this with map gas for the heat: http://www.bernzomatic.com/item.html?id=21

this is the silver I use: http://www.harrisproductsgroup.com/en/Products/Alloys/Brazing/High-Silver/Safety-Silv-50.aspx

the map gas goes a long way. way farther than a small oxy-acetylene tank set up will. barely costs a 1/4 of the price to get a refill and doesn't stink up the place like acetylene does. i'll pick it first over bronze, tig/mig or the sparkle box as it's the quickest way getting that tube attached to the muffler and it's damn strong. it also won't crack like bronze or an over heated tig weld will.
