Serious about performance, why aren't you running square ground?

[B_Turner]

Here's something I have often wondered about:

There are lot of folks here that spent a lot of time and effort trying to sqeeze extra speed out of their saws. Muffler mods, porting, etc. Good stuff.

But to me if a person is really serious about a real performance gain across all saws why aren't they running fresh ground square grind when using flattop chisel chain?

The difference is cutting speed is huge and I don't think the edge holding ability is as much worse as most think as compared to the same chain round ground chisel. I find in fact the reason it seems to lose edge faster than round ground is partly because it was so much quicker cutting to begin with.

Ask anyone that runs fresh ground square chisel and they can't imagine otherwise. (Again not talking about when needing semi chisel for dirty stuff, talking chisel only.)

atleast over here they dont sell full chisel square nor full chisel... those :censored:

Is that true? Unbelievable! I'll mail you a loop if you want and your eyes will bug.

My dad told me that there used to be chisel (with round cutter) but there havent been any on sale for last decade or two.....

btw, is it available as .325?

So all your cutting is with semi-chisel (not flattop chisel)? You are getting cheated in life.

Not seen a square ground .325, and my square grinder wouldn't deal with chain that small.

Not seen a square ground .325, and my grinder wouldn't deal with it anyway.

yeah, semi-chisel (like h25 etc...).... Meh, if i had a 3/8 setup for my 353 id love to try real chisel chain...

I would guess most dont, due to the in the field touch ups of hand filing.
When your tired from the work, it would be a pita to do in the field, i would think.
I have a hard enough time doing the square chain in the vise one tooth at a time.

I guess that make sense, as most here like to touch up their chains on site. I bring a bag of chains for each bar for each saw as I would rather just cut and sharpen sometime later when I feel like it.

Especially on a larger saw, I could never go back to round ground when using chisel. Once I felt the clean bite (and crisp chips) ofva freshly ground square chain I was hooked anything else feels weeney.

My 7900 with a fresh square chain is nearly a religious experience. When I accidently get out a chain that I sharpened before I got my square grinder, I usually take it back off and put it in the to be sharpened queue.

+1.

That and the fact that an Oregon 511A is a lot cheaper than a Silvey.

WHen I was using SC I meant semi chisel. I don't know the standard abbreviation for square ground chisel or round ground chisel (both flattops).

In terms of manufacturors labels, I use Stihl RSLK which is square ground (L) chisel (flat top) and with Oregon CL or CLX (both square ground flat top chisel , the x is the duropro which is a wider cutter and allegedly a tougher cutter).

Maybe someone can offer standard abbrevs? Using Stihls or Oregons is confusing...

Blis, you should be able to get your dealer to take it home for you, maybe not squareground but surely some round chisel.
Husky has it in their lists, both small mount bar and rims för 3/8.
but the chiselbit files to file square ground is a bit trickier, I got my files from D.Neiger have not been able to get any of those her in Sweden .

 

[wdchuck]

I have to hold on tight for the first bite with Stihl RSLFK, it's crazy fast compared to other chains I have used, just wish I could file it to maintain that great cutting ability.

Patience grasshopper.

 

[Cut4fun]

I found Madsen's carriers square 6 sided bevel files in good quality as the stihl square files were. I also tried woodsman pro square files and wouldn't recommend them for anything but a raker file IMO.

Madsen's site is down, do you have a part/model # or is their only one kind?

I'd really like to get the same performance, new to many uses, and the round file just doesn't do justice.

Wait until you try one fresh off the grinder. It will change one's idea of what sharp is. I run 36RSLFK mostly on my longer bars. It makes the saw seem like the next size up. Even my 42 inch bar sings pretty well with it on my 066 or 395.

That does not keep me from dreaming about a bigger saw, though but that is a different thread.

Anyone that considers themselves serious about performance and hasn't tried well sharpened square (Oregon CL out of the box needs resharpening first) needs to try it. Be square or not be there. Maybe that will be my next sig.

 

[SWE#Kipp]

I have only tried Pferd chiselbit files and have now ordered some Wallorbe files, is their someone who has tested them ???

 

[motosierra]

what brand of square grinder do you use?....and where can I get one?

I went to my dealer and tried all the models of Silvey and there was one that was heads and shoulders better than all the rest of the Silveys. I am very demanding in what tools I use so the choice was very clear for me. Pro Sharp. Pretty expensive, but I'll be using that grinder in 20 years god willing.

More accurate and rigid than the others, and the chain is held in 3 ways which makes me unwilling to consider anything else. The final kicker was the design where the wheel wear does not affect the angle.

Other folks with more skill patience and experience can get great results with the less expensive models, but my tools are my one extravagance in life.

I got mine at Madsn but Baileys (sponsor) sells them and are great to deal with. Price not for the weak of heart, but I could never go back....I think TreeSlinger uses one, see if he'd give his up.:hmm3grin2orange:
