I am pretty sure I still have the 1st cylinder he built me, I will take a few pics after work.
I know a lot of grinding don't always make a strong saw, and a rough grinding won't always make a poor running saw, but the first one was far from perfect, it was fine and the saw was really strong. But it failed, a whole part of the cylinder broke in the middle of the lowers. Another member told me this could be because of the poor grinding, I don't know if it's true, but for me, it wasn't a big deal, it was my 1st ported saw and she last me a good year or more.
Then, I replaced the jug by a new one ported by Brad. And I can't tell you how impressed I was by the quality of his work. Everything was smooth and shiny.
Of course, the saw was not MUCH stronger... But it was.
And this cylinder has today at least twice more running time and it is still perfect.
2 weeks ago the piston ring pin broke and destroyed the piston, but the cylinder should be salvageable and I will rebuild it.
So when I saw the quality of the porting job on this saw, I knew from my own experience it won't make the saw as good as the 1st one, and I know it won't be reliable.
Glad I see it before it failed, the saw is brand new and a good 346 case became hard to find.
