Square VS Round

[junkman]

Thanks, I got ya know. The thickness of the side plate cutter height.

This is the only spot need to sharpen if helps out ,between the arrows ,the winning chain sounds like 1/2 or 1/3 of the side plate was sharpened

All of the area in the box is for is moving chips and breaking them as they curl up if they're that long. The little bit up top is what's cutting the edge of the fibers. The top plate does 80% of it. Look in the CPD thread in this section at the next to last picture Shaun put up. That's the PS I was talking about. Some of the fastest chains I've made barely have a side plate.

Here's Shaun's pic to keep following this easier.

I could see squared corner then rounded up near corner on the above chain. I am guessing that is why he called it hybrid.

Finished the 272 build today so will be checking over that ported 026 with 12" picco set up next.

The fastest chain on the 63 PS in the work and race category looked like round filed and had a very short side plate. The side plate doesn't have to be tall. Just .050-.080" is all that is touching the wood any way. The raker depth is pretty much all the side plate that gets to work. Cut down into a cookie and kill the saw at WOT with pressure on it. Break the cookie off and look at what the chips, cutters, and rakers are doing like that. A lot more stuff will make sense then. Not every cutter will bite the whole time.

Matt (Hedgerow) showed me this trick in Iowa this past Spring. I wondered why he stopped and broke that thin slice of cookie off with the saw half way through the cut.

Lots to learn looking at that.. Thanks for sharing that Mike.

346 xpg - FTW!!

It had the benefit of a true square top plate and corner, and tons of room to get rid of debris...
Very well thought out on Shaun's part I thought.
Worked great!!

Looks a little fragile for the rocks i cut sometimes .

Got a lesson from a chain hack, lol.
Been milling a bunch on full skip square with great success as well Mike. Its been holding its edge a lot better than I would have ever thought. Now that I finally have some files on the way I can practice more. Pa gtg is comin' up soon

 

[concretegrazer]

That aught to chew up some wood.

When is the next PA gtg?

 

[Wolverine]

Usually May but I'm sure we'll do a mini next time you are up.

I was hoping to get up there soon but doesn't look likely for another month.

I use a goofy file in most cases when I hand file....

I'm liking the goofy file...

Squarefile is witch craft stuff, and all!

I need to try this black magic voodoo chain stuff

Likely a dumb question but can you square file round ground semi? As in, is there any point?

The Goofy File is black magic for the brotha on the street. It's all around the best tool in my box especially on square chain and pound for pound dollar for dollar. If you can have one file there's no other logical choice.

No. Wouldn't be any point (pun intended ). You can convert round chisel tho.

It's not true except for the pun. I've made semi-chisel converted by goofy file and is insanely fast and excellent durability. Even .325 chain. It's a tight squeeze. But it almost makes a tunneled hybrid square effect with rakers taken down as a collateral damage because of the angle and relative motion the goofy is at to get under the tooth. A little shaping on the DG and the stuff is bad.

In the mean time I've been goofy filing for the practice.

I dunno why it seems almost nobody but Mike Lee and me is listening to this. Sometimes I think they named the goofy file the wrong thang and men are ashamed to use it. We used to laugh when we were kids when they talked about funny cars. Wasn't really any thing wrong with them bad SOB's just a silly sounding name. I'm a firm believer in the goofy. It's the best of all possible worlds. Nobody listens.

Randy, I don't see much point to the Goofy,

The goofy file diminishes both

MustangMike you're crazy. What the goofy file diminishes is cost and lost efficiency. Those are things that need to be diminished unless you have a big assload of cash.

Filed this side left handed for the practice. Not bad for the off hand. Milling is beating the bottom of the chain links up. I cut about 160 bd ft with this chain in the last week on 4 touch ups.

Pics of a goofy filed cutter? How much do they cost?

I'll try to remember to put up some pics.
