      I'm going to try my hand at brazing new carbide on some chipped and   
   worn boring bars for my mill . I have 3 choices for heat source , O/A ,   
   TIG , or my induction heater . I also have a couple of choices for braze   
   filler , phosphor bronze TIG filler , regular brazing rod , and silver   
   solder if I can find mine . I also have some brass wire , composition   
   unknown and a few sticks of silphos , though I don't know if that will   
   stick to steel . I also have both borax and regular brazing flux .   
      
     The plan is to heat and remove the old/broken insert , apply flux and   
   a thin piece of brazing filler topped with a new carbide piece , and   
   heat to brazing temp . After watching a couple of youtube videos it   
   looks like I may need to hold the new carbide in place as it heats/cools   
   , I'll probably use a piece of SS TIG filler for that .   
      
      I just realized that I can replace the carbide teeth on the face mill   
   that came with my milling machine . I tried to sharpen the cutters on   
   the lathe , turned out less than optimum . If I do that I'll use the   
   indexing device I built for sharpening end mills to sharpen them . Might   
   try that to even them up , might turn out I don't need to replace them   
   right away .   
      
     Thoughts on heat source and filler selections ?
