what is it for?

 

[pbillyi69]

i square ground a small stihl chain for a co-worker that may have been the chain that came out kind of like hexa chain

what is it for?

23rsp is real fast out of the box. Hard to duplicate, hooky and delicate. I think @Armbru84 tried squaring it now that I think about it. Said it wasn’t any faster. Maybe @PA Dan . But maybe square could be a little more durable, less grabby, and sever chips vs. choking on them better. @species8472 do you guys race it round or square?

I have a couple of loops of this carlton 325 that I hate. It's cutter is a strange Hight and nothing really fits in there great so I tried this. Pferd 3 square file. No idea if it works yet.

I ran a 16” loop RSP for an unbelievably long time. I think it is some kind of hard alloy. (never tried hand filing it) Finally hit a rock while cutting in snow. I square ground it and was equivalent, but not better than the factory compound grind. I have a bunch, just in case the outlaw the stuff! lol

Dolmar 099, round ground and gullets cleaned out by me on my AMA MaxxPro, rakers set with an Archer FastFiler roller guide and rounded of with a dremel tool.
This was after 3 tanks of fuel worth of bucking oak & beech logs with my Dolmar PS-6100CE, the chain was still self feeding.



I ran another tank and a half of fuel on that loop today.
Will check current wear tomorrow, or whenever I get the to it.

Following up on this. Didn't work, Still cuts like crap. I hate this chain.

Hopefully this might help someone when starting out with square.

The first pic is the side plate when filed with a Pferd 1250 DKT 175 hexagonal file.

Second is with a Vallorbe hexagonal file.

Both are the same design but have a different overall diameter. The Pferd is smaller overall but has a larger flat section that forms the side plate angle. The Pferd fits better in more chains and has a less aggressive cut than the Vallorbe.

The finished results with both are less photogenic than a double bevel file, it's just not as pretty but I think they are more effective.

Learning to use one is a up hill struggle. If your starting out use a double bevel at first.

More updates,

Polar opposite of the carlton .325, this A3LM done with a Pferd 3 square is probably the fastest and smoothest cutting "work" chain I have ever used. I would take this over RSL every day.

It's pure crap round filed, factory grind is awful but the thin top plate is really well suited to square. It's hard to believe the difference.

Have you tried 23RS Pro chain ?

Not yet. I don't have any 050 325 bars at this stage

Round Hexa, attempt number 2. First time was with a 2 in 1 and it cut horribly. Bounced and jerked, just to much side plate angle for the wood I'm cutting.

This time filed 25/10 with a 7/32 and a reduced side plate angle. Much better.

Difference in cutting speed Hexa shape to this round shape? Zero. Averaging them out there is about 3% difference with the round being slightly ahead. Feels the same in the cut.

Looks like a fantastic dry hard wood buster

 

[Moparmyway]

Which one cuts faster ?

Which one lasts longer ?

Gullets will be filed back, same depth rakers on both chains. Angles are identical, only difference is that beak
