any of You folks using it ? How bad is the learning curve on sharpening ? Is it worth the effort as far a chain speed ?
 
You're talking about square ground/filed chain? I haven't tried it mostly because it's supposed to be darn near impossible to hand-file and I do not have a grinder.

Supposed to cut faster than round-filed chisel chain but dulls faster as well.

That's exactly what I'm talking about . I may just get a few chains just to see if it's hype ,or fact . As far as sharpening .....If I like it , I'll buy an Atop jig to do it . they aren't cheap at close to $200 . Bailey's - Atop Square Filing Guide with 2 Files
Like You said , it's darned near impossible ,so that's why I want to try it . a 20+% increase in cutting speed is worth chasing .
 
Try it & give us a review.
That's part of the fun, try some new things & ideas
Keeps some fun in the game ;)

I believe I'm going to . But now as to the review ....Y'all will just have to take my opinions , No pics ,and definitely no vids . :)
 
LOL ;lol

It'll be fun
Your opinion will be good enough. ;)
May need a bigger saw with more HP to throw a square chisel. ha ha

Aw, come on. I've never seen square chisel.
neither have I ! At any rate , the chain (2 72 dl ,and 2 84 dl ) has been ordered . Also the ATOP jig . Like they say ... in for a penny , in for a pound .
And before it's mentioned ....... Yes , there is nice jewelry involved in this venture . :)

I'm working on the bigger /more hp dream right now . there are rumors of a 572 xp auto tune in the wind . Personally , I was hoping for a 595 xp auto tune . :)
 
Thanks mike ! Have you used it ?

Nixon, if you're buyin' the hardware, I'll provide the review production. ;)

Just say "no" to a square ground for what most of us use saws for.
It is not just the learning curve for sharpening, simple enough with practice. The chain is for strictly clean, fast cutting.
Firewood harvesting and bucking means grit, dirt that quickly dulls a square ground, besides 'grounding' a chain or rocking one such as discovering a round in a tree, barbed wire, fencing,
or nails. Bad enough to see sparks on a cloudy day!

Advice from the pits ? Stick to shorter bars ~ 16"-20", and round or semi chains. No need for the macho 36", square ground chains, or MS880 saws for what you do.

My newer MS261 with a 16" bar and "yellow" chains does 99 44/100 % of the yearly firewood, pulp, and blowdowns for this coastal Maine woods; trees rarely larger than 24" DBH. The shorter bar is easier to handle, sharpen, carry. And yes, the 16" bar will easily do a 24" butt.

No its not worth the effort or expense! (Unless you have a real need for speed) Better be making good money to support the cost. :eek: Good file alone about 15.00.

20 percent extra speed with a chain will take more than atop(Race Chain). Proven race chains will go for "BIG MONEY" And remember your only looking to do 3 cuts with it before its re-sharpened.

*The following is just my opinion based on a lifetime of experience, and the experience of the lifetimes of others growing up and living in a logging town*

1) I am not using it

2) It is no more difficult to sharpen than round bit chains - the principles are identical - but they do dull much more quickly.

3) Unless you are falling the trees and bucking them before they get a chance to sit on the ground very long they are not worth the extra cutting speed.

I have a loop of full chisel square grind but I never use it. The square filed chisel tips are so thin anything will bend, dull, chip or rock them. Then filing them evenly and at the right angles is really hard to do. I use round filed semi-chisel in crud, on stumps, dirty and gritty wood. Semi-chisel cutters stay sharp a lot longer. The curve in the chisel deflects a lot of crud that would otherwise dull a full chisel point. They are also easier to file than full-chisel. I use round filed full chisel in clean wood, as round filing gives the chisel point a lot more support.

Rule of thumb (from Madsens) is that square filed full chisel is 10% faster than round filed full chisel, which is 10% faster than round filed semi-chisel. I doubt that you will get 20% gains from square filed full chisel over round filed, unless you are doing three cut cookie race cuts in squeeky clean wood. I have found that semi-chisel stays sharp a lot longer than full chisel. If you want a better cutting chain use non-safety to get rid of the extra rakers and keep your rakers filed right. If you want to get better torque or speed in the wood, change the rim drives to give you better control. Larger rims will give you more chain speed, and faster cuts in many situations. Smaller rims will give you more torque and more pull with less bogging.

As for shrimpy bars always being better, that is not the case in my experience. Making one cut from one side is usually faster, cleaner and you get better face and back cuts, as well as falling hinges. If the bar seems long, go to semi or full skip chain to keep the chain speed up, or reduce the rim size to get more torque. It all depends on what wood you are cutting of course, the type of cutting (cross grain or with the grain) and what size saw you have. And it helps to have an outboard clutch to make rims swaps. Short loops may be faster to sharpen, but they are also faster to dull. I have found that a few inches either way in bar size does not make that much difference in how they handle, especially with larger saws. I have found that longer bars do better in all around cutting myself, but then I suffer from PNW long bar disease. ;)
 
Thanks for the advice and opinions guys. This is just one of those things that i've been meaning to try for a few years .
If it works out reasonably well.... Great ! If not ......no big loss in the grand scheme of things . If nothing else , it'll help keep an old fart occupied .;)

Might try a part-time gf......;) Could be cheaper and make "You" faster! lmbo

Well the ATOP ,files and chains arrived this AM . Still trying to get my head around the angles of these chains . Shouldn't be all that hateful to learn with the jig . As soon as I'm done cleaning up all the dead-falls from this winter , I've got a few Aspen and Tamarack to drop . That should give the chains something clean to work on .


Nixon, if you're buyin' the hardware, I'll provide the review production. ;)
If you're serious , I can chuck one(chain ) in the mail . Do You want it new , or butchered by Me ? Oh ,and I get it back after the review , right ? :)
