What will be the fastest cutting STOCK off the reel .325 chain in the chain build off rd 3? Will be using 8x8 white pine cant. 57cc-60cc saw and 8T.
-
Well it looks like the Stihl RS is coming in with a high rating.

Only reason I went with RS was the gullet of the chains coming stock off the reel.

I figure by the time you get to modifying a race chain that it really does not matter that much on what you start with. I guess if the cutter height is higher that could be an advantage but how much in .325 I do not know. It seems to me a lot of other things will come into play.

Yep
I did notice even though RS dont have the bumper link like the LPX. I would swear the RS felt heavier picking up.
Can anyone weigh the 2 loops stock for stock?
or have a scale I could use to check local.

Like I said on the .325 build thread the narrow kerf 95VPX even though it's semi chisel, it will surprise the .325 chisel users in stock class 8X8.
The new 95TXL is supposed to be even faster.

Now you made me go look stuff up. ;)
Oregon 95VPX G-Series Saw Chain
95VPX chain is part of a Micro-Lite™ narrow-kerf cutting system that requires less power from the saw to cut than standard cutting systems and meets the ANSI low-kickback standard. https://www.oregonproducts.com/pro/products/chain/95VPX.htm
(https://www.oregonproducts.com/images_pro/products/detail_95VPX.jpg)
Oregon 95TXL Work faster, sharper, easier, with a more efficient chain. Ideal for arborists and property owners who want top performance. 95TXL is for saws up to 55 cc. (Replaces 95VPX.) SpeedCut™ 95TXL narrow kerf cutting systems are more efficient, needing less power from the saw than standard cutting systems. Low-vibration, Micro Chisel cutters have small-radius working corners for excellent performance and easy maintenance. Get a faster, easier cut with a reshaped cutting surface. A sharper, more durable cutting edge from a new precision grind and optimized cutting angle. Always use SpeedCut narrow kerf chain in combination with SpeedCut or Micro-Lite bars. https://www.oregonproducts.com/pro/products/chain/95TXL.htm

That top chain 95VPX looks like Vangard chain. I suppose that's what the "V" stands for?
-
I dont think it has the bent raker Jim like vanguard.
If you remember VX and VXL was also 3/8LP semi micro chain
-
No bent over depth gauge on the 95VPX. Same style as the LPX just narrower.
91VXL is the lo profile 3/8" semi chisel. Still waiting for Oregon to introduce a 91 series chisel.
-
I'll have all 4 of these stock to test in the chain build off.
-
Really should have some good info by the time you get finished with this.

Did a little testing today regarding .325" build off chain.
Figured it would be better posted on this thread and not clog up the build thread. Hope this it is helpful to you guys.
I know I've learned a good deal from this exercise.
The first thing I did today was just kiss grind the rakers on the Stihl RSC that I Square ground the other day.
Near as I can tell they are set to .022" I did this more to "even up" all the rakers. This takes out any irregularities/Inconsistances as far as height from the manufacture. Very minimal material removal.

Next I thought it would be good to compare that square grind to the two factory chains I have ordered for the build off.
I ran the square grind first.

And finally last but not least I ran the Sthil RSC factory off the roll chain. completely unmolested:

In conclusion I took the following pics
that associate the chip size produced by each
of the chains in the video's above:
.325" Stihl RSC Square Ground Kissed Rakers:
-
.325" Oregon LPX
-
.325" Stihl RSC (Factory Edge)
-
Final Thoughts:
I was surprised the Square held up fine with those angles.
Even more surprised at the length of those cross cut chips.
Had a bunch 4"+ and a few 5" in length.
(I've never seen That before)- Kudos to Deets for his help on this one.
My suspicions are that Stihl RSC may have the best results for the following reasons.
Slightly taller cutter, no saftey Bumpers, thinner raker, thinner rivets,Better (larger) chip flow channel.
That why I'm putting my $$$ on Stihl RS for the .325 build-off

Well we will see. When it comes to the race chains they go through one heck of a transformation so I think it is any ones game.
That is a pretty long noodle, but that could be from chip clearance like you said.

Good info. Thanks for sharing. What kind of wood are you running in?
-
Back when I made a living logging we tried everything going for chains. Ran .325 on small saws for softwood 242-357 Huskys. 21lp was the hands down favorite for most crews. 95vx was decent up to 50cc but on 254 or 357 lp was quicker. Had a lot off chains breaking in 95vp and bar tips were weak.
At the shop now the remaining pro guys still buy 20/21lpx, only homeowners buy RS.
As for fastest chain out of the box probably RS,but to quote our Bowater instructor, " if you think a chain is fast out of the box, you need a filing course"
Have fun, if someone can find an old loop of 33LG watch out.
Why 50 gauge? No 58 in US?
-
New England is .058" but in the central USA if someone is stuck with a .058" bar, he'll run .050" chain in the bar until he wears it out. No one stocks .058" around here in Ohio.
-

It's Lodge pole pine.
It was all I had. Buddy of mine is going to bring some
test logs tomorrow.
-
Have fun, if someone can find an old loop of 33LG watch out.
I have a partial roll and 2 new loops in 33LG made. Its in the list of choices in first post.
My friend likes the 33LG on the 16" 353 I set him up with.
050 is the poplar chain in my area not 058. I cant give 058 away.
The stock ones are being run untouched. They are to compare to the work and race chains we are doing in the chain build off.
Do one up Art. ;)

Could I purchase a loop of 33 LG ?

Chris all of mine was spoke for local. I have 2 loops left for testing 1 stock 1 I am going to file.
might be the ticket http://www.ebay.com/itm/Oregon-16-Chainsaw-Chain-33LG-066G-NEW-/310659425814?hash=item4854bea616:m:mx_P8nLLQwMoVdjrdU9bQUg

Oregon used to claim 20LP was 6-12 (or so)% faster for any kind of cutting (specified), but never said on which saw...

You would have trouble giving .050 chain away in regular .325 or 3/8", except in certain areas of the US. .050 also is a quite meaningless gauge today, as it just is .058 chain with stamped down drive tangs.
Also, I suspect many of the voters here never really compared RS/RSC to LP/LPX, as there is no doubt the LP/LPX is the fastest cutter. The difference isn't large, but it is consistent in the comparisons I have done (21LP vs. 25RSC). I happily use both for practical cutting - but that's where it stops with .325 chain.
I suspect the votes reflect how the different chains looks, and not how they actually cuts (dangerous statement, but so be it).
-
I've only used one 325 chisel loop in the last 6-8 years. It was RS to try on the bars the dirty hippy sent me. I got Oregon since that's what Stevess had to give me at that gtg. I would liked to have done a race chain but no tools to do that in the motel.
-
I think they both cut well. I have found that Stihl chain holds the edge longer than Oregon chain. But in general I have found the Oregon chain is faster with how I file my regular work chains
-
I am going to try and run all 4 stock chains in the same 1.5' section of cant. That way they are all in equal wood all at same time and no knots etc No excuses then. ;)
-
I have the following .325 chain if anyone is interested
Oregon 20AP .050
Oregon 33LG .050
Oregon 34LG .058
Oregon 35LG .063
Oregon 19 .063
Homelite DI .050

I split post and set you up with a for sale thread in for section too.

What I am really wanting to see. Is the 3/16 stock LPX really 8% faster then the smaller 5/32 LG33 it replaced. Just the cutter difference in file size should cover that I would think. That was LP, would think the LPX would cut same or faster then the LP
Then I have a 3/16 filed LG33 to throw in there as I just hit the front of cutters on a new chain.
Found it in my old oregon 33LG thread here. 8% bucking, 18% boring http://www.oregonproducts.com/pdf/chain/20lp_flyer.pdf

That's what Oregon used to state, and 30 series LG has been history for a while now. I believe the similar Stihl TS was discontinued even earlier.

The way I seen these stock chains in the cut.
K1L felt slow and rough through cuts. Vibrations.
33LG felt smooth through the cuts and faster then Carlton.
RS felt faster again but more vibrations felt in the cut = rough.
LPX felt smooth through the cuts. Cut better then I thought it would stock with the gullets the way they are from the factory. Felt like it cut with or close to RS.

Yes stock LPX was faster the the stock LG33
Think the stock LGX was also faster stock then my 3/16 round filed touch up cutters on LG33 too.

No real surprises there, except I would have expected the LPX to be a tad faster than the RS, as well as smoother.
21LP was a tad faster than 25RSC in my comparisons some years ago, with a 346NE and a 5100S (both minus spark screen, but otherwise stock).
-
According to my timing the LPX and the RS were very close.

Just had to share as it made me feel good to hear.
The 325 chain build off work chains I did. One of my regular firewood cutters ended up with them because he runs 16" 325 on his 353 as he wants light weight set up.
Yesterday he was in getting saws looked at and he said I dont know what you did to those chains but I want you to keep doing it.
-
This is a old thread and I like Stihl RS .325 chain. If I could get it at a good price I would use it But .325 chain doesn't last too long and I can't tell if it's any better than LPX chain. You never know when you're going to hit something like a rock and mess up a new chain so I use the less expensive LPX loops. I run 72 DL LPX on my 357xp with a 8T sprocket and can cut up a 20" oak for fire wood with out the chain getting dull.

Guy I been setting up with stihl RS 325 063 74dl for a 271 in past.
I talked to him about trying 22LPX to compare and see how he likes it. So today he took home a new loop.
See if his feedback is like mine.
Think he said he had a dead ash to drop.

Billyram, no need to run .325 on a 357XP. You got all the power you need to run 72LPX. But try a 7 tooth rim sprocket on that 357 in oak or whatever you cut and you'll thank me.
.325 23RS I run on my 562 XP-18" and it's perfect for that saw.

Was you in the 325 chain build off? I remember you in the 3/8 low profile picco chain build off.
I'm done with all this type stuff chain build offs etc. Anything to do with racing etc. Just watching now days.
I always said when it is no longer fun for me I'll walk away. The chain build offs was the last thing to walk away from.

think you got that right, picco. only thing that chain would be good for is maybe tire chains. fun is what it is. always something else out there. if going to watch something fun, lately been into watching in car camera rally racing.

Well I really fell for the Oregon LPX while doing this testing and now I see them have the Oregon 325 chain in LGX now too.
Guess I will be ordering some 20LGX next.

I have had the oregon .325 LGX in hand for a bit now. Just never compared it to the LPX I have NIB yet to see.
Anyone else buy any and have feedback?

Timing last 2 cuts of LPX were fastest. But what I noticed most (could have been just that section of wood too) . The LGX didnt vibrate like the 325 RSC RS I ran before. So from now own either or is good for me. But will order LGX 325 from now on.
