I had to run semi-chisel today, no joy

[B_Turner]

Spend a bunch of today cutting wood that was gritty enough I had to get out semi-chisel chain.

I had forgotten how un fun it is as compared to square chisel. I just don't enjoy saw when I have to use that stuff. I'm spoilt...

It's like cutting with square where the edge is first gone, although it's stays that way a while before it stops cutting. I started with square and then switched to SC because of all the grit in the bark, so I was able to see if the SC was running hotter than square before the square went dull. Much hotter.

LOL! I don't think you would want to square file semi-chisel, I don't think it would cut to good or at all! LOL! I like semi-chisel also, but for firewood, and real dirty logs on the landing. I use round chisel bucking logs at the landing, the key is to have the chain pulling the dirt out of the cut, not into the cut.:greenchainsaw:

No Joy??

This is a classic " Is the glass half full or half empty" scenario. Which means the lower cutting performance can be rationalized I just repeat this mantra when running DG

" I'm glad I'm not cuttin this crap with my chisel chains"

I posted here a while ago about getting a roundtooth chain for my 394-30"bar, I was kind of choked. I use the saw for bucking firewood and a little falling. Anyways after cutting into a few nails it sure was easy to file it sharp agian.

I mind semi-chisel less in softwoods, as softer woods cut easily regardless.

But most of this was somewhat dry black locust, which is a fairly tough wood. The square was smoother in the cut, but these logs had been handled enough (dirt and small rocks in the bark) that semi-chisel was the most practical way to go.

The difference in the shavings/chips created was pretty dramatic with this stringy stuff between the chain grinds. Big square chips with the square and a mix of chips and smaller stuff with the SC.

Also the semi-chisel was ground on my 510 grinder, and I will admit that with a really good hand filing my round chains cut a LITTLE faster than ground. I run enough saws/chains that I seldom take the time to file on 3/8 round anymore.
