I've noticed this before but it was very apparent yesterday bucking some big white oak. If I try to cut a small round and stay standing up with the outer 1/3 of the bar it cuts slow and lots of dust. If I drop the saw head a cut right at the dog it rips through like butter so not a chain issue. This is a 20" rollomatic es .063 on a 441c No visible bend in the bar with a straight edge on it.
Sounds like maybe the chain is sharp but the rakers could be a touch high? You get a little extra leverage down near the dogs which could be helping the chain take a more “normal” bite.
Yep I agree with Shawn. Drop the rakers a little more and the chain will start to self feed in the cut.
Thanks I'll check the rakers. I thought I set them at 15-20mils last time all the chains were sharpened on the vise. The bar does not have any flared edges.
The depth gauge measurement tool that came with my Oregon grinder states. .030 for 3/8 chain. .015 is definitely too high.
So I got a new granberg file n joint as my old Viking plastic unit finally broke. Took the cutters back a good bit and set the rakers at .030 The chain screams through cutting at the dogs and still cuts like a turd when standing. Starting to wonder if the anti vibe bushings in the powerhead are allowing the bar to torque when cutting with the bar end?
