Barrel replacement illustrated

[John Sabato]

I haven't needed rosin but it's a good idea (I don't have any);

Just buy yourself a bowler's resin bag

... or at the local bowling alley shop. There is enough resin in one of those to do dozens of barrels and you can reuse it most of the time if you are careful... just keep it in a zip lock bag...
