I have a Husqvarna 55 rubbish saw, ~2000, 18" bar, 51cc, 2.4kW@9k,
used mostly on hardwood in VERY sandy conditions.
The original bar/chain is: 72DL, 0.325 pitch, 0.050 gauge, 7T sprocket on tip
the bar has both worn unevenly and warped. It no longer cuts straight,
creating a sharp arc and binding badly when it gets deep enough in.
I've flipped the bar over and this helped considerably. But there is
still a warp in the overall bar and so it's cutting action is still
less than straight.
1) Bar Recommendation: Stay with same size bar or consider a 20" bar?
Any specific recommendations for 18 or 20" bars? (Oregon does not
offer separate bars for this particular application) I'm planning to
stay w/ 0.050 gauge absent alternate recommendations.
2) Chain Recommendation: The chain I'm currently using is Oregon
G-Series 95VPX. Good chain or consider something else? (for hardwood
cutting in my case). I'm thinking I can change the sprocket to 3/8
0.375 pitch. The same saw was available back in the day as the '55
Rancher' but came w/ the 3/8 pitch instead.
3) Ripping Option: I'm planning on doing some lumber ripping on a very small scale
(think mini Alaska mill on 6-8 inch hickory or oak logs). I've read
mixed reviews on dedicated ripping chain vs standard chain. Other than
a smoother cut, some say it's slower less efficient, others faster...
So any recommendations here?
Summary: So I'm looking for a bar/chain recommendation and optionally
a ripping chain recommendation.
