I have spent the last few days reading everything I could find on best/ideal/preferred bar size and nose type, chain style, chain pitch and gauge, and sprocket size. The general conclusion is to go with what is commonly sold at your local shop, with some general guidelines. It also seems that some of the guidelines are split at the 50cc line. I have listed my thoughts below and would apreciate any comments, note my saw is an older 49cc saw which has more torque than speed and will only see occasional use but is my only saw.
- Bar length – 16”: can’t think of any time I came up against a tree by myself any larger than 16”
- Bar nose – sprocket or hardnose: I am on the fence on this one, comes down to likelihood of locking up a nose sprocket vs chain wear & increased power consumption, or is all of this a non-point
- Chain: thinking some kind of semi-chisel
- Chain pitch – 3/8” or .325: this one seems to have no clear answer, suggestions?
- Chain gauge - .050 or .063: would going with the larger gauge have any drawbacks other that potential availability, or is there another aspect to factor in?
- Sprocket – 7 or 8 tooth: probably go with a 7 tooth rim sprocket
