Nice tooth

this chain is just plain sexy.

I would recommend homelite410 vice to anyone attempting square ground . His vice works awesome ! @Homelite410

One old timer logger's saw had the gullet completely gone right down through the top of the chain link. While I think this is an oversimplification, it does make the point of more room is better.

More room is better for chip removal .the larger the chip more room is needed.

i keep my gullets filed out i run my rakers a little low and keep my chain razor sharp.
unlike wranglerstar on YT he can't clean or file a gullet to save his ass.

. . . what about filing methods for the sole purpose of clearing chips?

Of course, skip tooth chain will clear more chips in big wood.

Some racers will grind cutters way back to reduce weight, and clear chips faster - but that is kind of a waste for working chain.

Some racers will also 'tunnel' - file or grind away under the top plate and inside of the side plate, to increase chip flow under the cutter. But this is also going to weaken the cutters on a working chain.

I just try to keep up with the gullets, filing or grinding them in a continuous, smooth curl from the cutting edges.

One of my "tweaked" picco chains. Started out as 63PS chain

Might be easier to start with just bare tie straps and raise a slight burr?

Anyone have a pic of the file you are using? A pic of it held in the tooth(at approx angle you use) would be worth 1000 words for me...

Feed conveyor?

It is off the Hart Carter feeder on my Frick thresher. I tore it up at our show last year and never got around to fixing it. Since our show starts next Friday I need to get going. I cut all my straps yesterday then slotted each end and drilled and countersunk the holes. I only needed 13 but cut 35 and ended up with about 25 good ones which will cover me for the rest of my life. My board was milled by Thick and Thin Lumber, I tossed 5 or 6 aside as they were not the same width. Got new bolts, washers and nuts tonight and will start rebuilding tomorrow.

The inside corner is very important !

Thank you, that helps a lot. As usual I was over thinking it.

Front of the rakers aid in pulling the chips out too. Not entirely sure what the best method is for this? Straight vertical on the front of the raker or angled back like they come off the roll?

I'd guess vertical

When I was at some chainsaw races I checked out the rakers on the chains, all of them were vertical.

There's several techniques for sharpening chain teeth with different angles and types of files/grinders. Then there is raker height to maintain optimum running speeds, but what about filing methods for the sole purpose of clearing chips?

I prefer a smooth cutting chain on a working saw so I keep my rakers a touch high. This preference is mainly for when I'm out felling, it makes the saw less jumpy while bore cutting for a trigger etc. I don't keep them so high that I have to push the saw through the wood, it still feeds itself. One of these days I'll have to measure my raker depth so I can share it...lol. I just go by eye with my raker guage and know how high they need to portrude to get the feel that I want.

When I was at some chainsaw races I checked out the rakers on the chains, all of them were vertical.

I figured that out not too long ago by trying to sharpen the outside edges of the rakers. All it did was lean the chain to one side causing the edge of the bar to hang up and free spin off and on throughout the cut. The bonus of that fail was noticed after I filed the front of the rakers flat and vertical to fix them.

On a new chain if you make cuts and look at chips then clean gullets chips will get twice as long. They can get to a point of being too long and clog easier almost like noodles. There's a happy medium to find.

Why do longer chips help? Less left behind for the next cutting to run into?

Keeps the tooth engaged a little longer. Cut a cookie and kill the saw in the cut and break the cookie off while leaving the saw. You'll see where chips ride and all the cutters doing their thing
