This is great information thank you guy's.
I push the file in towards gullet not down

I can't dispute anything you say here Philbert, but I think I will delete my last gasket to avoid futere damage.The role of the side plate cutting edge is often overlooked / underrated / Rodney Dangerfield'ed. Many say that it has the hardest job when crosscutting, because it has to cut/chop through the wood fibers. If there is too much 'hook', the entry of the side plate cutting edge is delayed until after the top plate has started pulling the fibers up. The 'self-feeding' feeling is the saw pulling itself into the wood, instead of cutting through it effortlessly (like a a light sabre!).
With enough power, the chain can self-feed and still cut efficiently. But on a smaller powerhead, or with too much 'hook', the same chain will try to tear the wood instead of cutting it cleanly.
As Andy notes, the 'depth gauge' controls the depth of the cut. Calling it a 'raker' is a misnomer, because the top plate is what really rakes out the chips, after the side plates have cut the fibers.
(I hope that Old Guy has at least one more gasket to blow!)

Pushing down would be dumb and counterproductive - I keep the pressure in and up.
Gullet filing is a separate operation, when needed.
I may have miss-spoken, "gullet" is bottom of tooth between cutter and raker? I meant I put preasure into the cutter, so the file rides the side cutter and top cutter at same time. (;0)

Speed.What would a square grind be used for?
it will dall faster but cuts a lot quicker. Most people who like to play (race or cookie cutters) use square ground chain.So square filed is not much for everyday use?
Not exactly a firewood chain for sure.I have a long ways to go before I even think about trying it anyways.it will dall faster but cuts a lot quicker. Most people who like to play (race or cookie cutters) use square ground chain.
It depends on the geometry used, square ground can in fact be very durable. The issue is the cost to benefit isn't that great for the average firewood cutter. Learning how to properly square file is time consuming, and at times somewhat expensive. Off the role square ground is usually pretty lame from what I've experienced, but I guess it's a good place to start.Not exactly a firewood chain for sure.I have a long ways to go before I even think about trying it anyways.
Sorry the pics are not better.I think my camera is going south.OK some pics of what I have been working on.What's wrong and what to do to fix it.View attachment 530084 View attachment 530085 View attachment 530086 View attachment 530087
