Another brazing job.......

admin

Okay..... This is a roller guide for a bandsaw blade..... make that a broken guide.http://i147.photobucket.com/albums/r...e/P1010007.jpgAfter cleaning I beveled the crack edges that are on the inside of the bore and brazed those joints first.... I then went back and gouged out the cracks from the surface side, making sure to gouge into the root of the prior joint, and brazed it up. One of the cracks went right through the threaded hole on the top of the part.http://i147.photobucket.com/albums/r...e/p1010009.jpghttp://i147.photobucket.com/albums/r...e/p1010008.jpgA bit of grinding with a flap disc, a trip to the Bridgeport for a new bore and a new threaded hole and......... http://i147.photobucket.com/albums/r...e/P1010020.jpghttp://i147.photobucket.com/albums/r...e/P1010019.jpghttp://i147.photobucket.com/albums/r...e/P1010018.jpgAnother happy customer......_________________Chris

Reply:Is it phosphor bronze?  I'm really interested in cast iron repairs and I want to know what works for everybody.  I brazed a bevel gear that split in half back together using Safty-Silv 45, it held together suprisingly well.  I tried to repair a water cooled exhaust manifold with the bronze and that didn't work at all.
Reply:Sorry 76GMC.... I forgot to check the rod..... I'll do it tomorrow. I wrote myself a note, now I just need to remember to take the note to work...._________________Chris
Reply:Originally Posted by lorenzoYou had to ask..... I'll have to look tomorrow....... I can tell you that it is a flux coated rod and I use a flux powder as well, pretty much when I begin or when I restart a used rod. As a matter of fact the flux can is in one of the pics that I placed the parts on top of it. The rods run really well. I'll let you know the rod specifics tomorrow.

Reply:A good trick to know when repairing cast iron is to finish all your bevel preparations with a file.  The grinder seems to smear the surface of cast and it is more difficult to get the alloy to bond.  If you doubt this next time you do a repair leave the grinding finish on one side of the vee and file the other.  You will notice a difference in the wetting action.  Also don't leave a sharp edge where the vee meets the top surface...  Round it off a bit.  These are just suggestions that some people don't know about.  These tricks give you that extra bit of strength.
Reply:great looking job on the braze. any idea if you could braze a cast door on a wood stove ??? or would ht heat cause problems after the job was done and the log's went in ??wow thats a lot of work on the boat cage, MIG shore would have made it go faster. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected] i got lots of time.

Reply:thanks guys i'll let my brother know its doable and he can bring it over for fixing. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected] i got lots of time.
Reply:A word of caution about brazing alloy at high temps.  The bronze will lose strength rapidly at higher temperatures.  As long as there is little strain on the brazed joint on the stove the brazing will hold.  If however the door hangs on a braze repaired hinge, the brazing might fail one day when you open the door to replenish the fire.
Reply:yep i understand that , if it was or turns out to be a hinge point i will revert back to my first thought witch was to stick weld it with nickle 99. but as i understand it its not on the hinge, just a crack in the side of the door. but if it has any stress to it i'll look at stick welding again.thanks for the warning though. summer is here, plant a tree for mother earth. if you dont have time or space, sponcer some one else to plant one for you.feel free to shoot me a PM or e-mail me at [email][email protected] i got lots of time.
Reply:What about silver or nickel brazing alloys?  Would they not work on the oven?
