Okay, I finally got the 395 back together and running sorta okay, still need to get the high speed carb setting right. I got lazy and just bought a Granberg - wanted to build my own CSM but will save that project for later. Setup a 'ladder' with sq. steel tubes that stayed remarkably flat with the weight of the saw on them. Anyway...got to where I did my first cut late this afternoon and it seemed to go okay. At least, I thought it went okay until I flipped the top section over.
Don't know how obvious it is, but the cut started off nice and flat and got progressively wavier - there's 1/4" scallops at the end of the cut. Now I'm trying to figure out what contributes to waviness in the cut and what I can do to fix it.
I know the chain is tired. It's a Stihl .404/.063 full skip with about 25% of usable tooth left. The guy I bought the saw from did a pretty good job keeping the gullets clear and the chain still seems sharp but it just doesn't seem to cut like it should.
I know the chain got a bit loose, but didn't seem too bad. It started off where I could pull the driver about half-way out of the bar, seems ok but maybe a little tight. Wound up able to pull the driver out of the bar about 1/4".
Thought I could have done a better job of keeping the CSM flat on the steel rails, and know I should have just pushed the saw through rather than wobbling my way through with my usual front-of-bar then root-of-bar CS technique. It's clear where the cuts cross, but the waviness just follows and doesn't appear to be caused by that motion.
I was *really* impressed with the 395. Really something to let it cool for a bit mid-cut and then just pull the trigger. No BS whatsoever, just get-er-done.
Would appreciate any insights that people can offer. Really want to get the next cuts right.
