Bunch of random pics of cutters

cool. i cant wait to hear how well this works. have you tried this before?

 

[davidwyby]

I did but I dunno if it helped, too short of a bar and not in a felling situ

It was pretty fast tho

I keep posting pictures of my 36"/115DL "hillbilly skip with a twist" but it doesn't seem to get noticed.
Take a full comp loop, grind off the top plate on every third cutter, do not touch the side plate, sharpen as You would a regular full comp loop.
You got a semi-scratcher chain.
Bucks and noodles hardwoods great, less clogging than with a un-modded full comp when the bars full length is utilized.

Nice work.

I decided to finally try square chain. Rocked it pretty good on my 4th cut so I get to learn how to sharpen.
Down the rabbit hole I go.
How's this look?

Practice and Patience is ur friend, ur blunt , witch is good in the wood ur cutting, just needs some fine tuning on the underside of ur cutter angles , angles vary with wood species, the sharper angle for softer wood and blunter angles for tougher wood ,try to match up top plate and side plate angles with a tangent line on the underside of tooth in corner we’re they both meet, 5 degrees forward lean is idea ,for side plate , cut ur gullet back to bottom of cutter with round file , Ur on your way and stay out of dirty wood, or ur good day will turn into a bad one real quick, Lol

Practice and Patience is ur friend,

Great advice. It takes a lot of practice to be able to do this and it's like learning to sharpen all over again.

I have now tried 5 different files to find the shape I like and have tried so many different ways of filing. My preference is for the Pferd 1250 TKD files.

Compared to the Vallorbe style of this file they have a slightly smaller overall diameter but larger flat sections for the side plate. They also have a less aggressive cut than the Vallorbes.

I file inside to out. Tried both ways but I'm more consistent this way. I also mark a 45 degree line on the bar as a reference line. I saw this in a Vallorbe video and find it helps give me a basic guide. I don't need it for small touch ups but if I'm converting round to square or have done some serious damage it helps me.

Who makes just a square 4 corner file?

 

[davidwyby]

Reminds me of an idea I had for square filing or at least learning. Start with already square chain and file one edge at a time. Don't have to keep track of so many angles at once.

Trying to avoid this:



Std full comp :



Sweeper cowboy skip



Seems to help a little but cut slower. I think the cutters I hacked back are dragging.

It’s crazy how hard that pine gets baking in the desert. 32” bar buried, took 50/60 seconds to cut on a ported 75cc. The rest of that is getting hit with 90-95 cc… fatwood

Your "sweeper" cutters still have a top plate that will bite.
My hillbilly skip version only features a side plate functioning as a scratcher.

Try converting Your mod to mine.
I'd love to know whether it makes a positive or negative performance change.

Won’t your side plate angle be wrong with a true square file?

I just posted it for the above question, if anyone makes a square file looks like a machine file not actual chain file, I use a double bevel myself,

I like round!
