Chainsaw Repair

I work at a technical college and have the benefit of a world-class welder (he teaches Certified Welding Inspectors their craft and also was a welder inside nuclear containment vessels) as one of our instructors. I asked him about welding on saws....the bottom line is that he welded a fin back on a 346NE. The piece was missing when I got the saw. I had another cylinder that was beyond repair. I cut the fin on and fitted it to the missing stub. When it was cleaned it up, you could hardly tell where he had been. He has also TIG'd a CB mount and repaired a crankcase fracture on 346's.  On the CC and CB repairs, you will need Mg rod and I couldn't find it locally in small amounts. It was $150/lb with a 3# minimum. I did find someone on Ebay selling it for $2.50/3ft length. The shipping was $13.50, one stick or multiples, so I bought a handful.
