Ripping posts
Did a bit of chainsaw fiddling today....I've had some people talk about using .404 chain for ripping posts and some people talk about using .325 chain. I've just used 3/8 as that is what was standard on my saw.
Decided yesterday was the day to run some tests...first got hold of parts needed to fit the 395XP with .325 chain instead of the 3/8 I normally use. To make the test about the chain as much as possible, I had two ppl timing who only timed when sawdust was flying, this way any discrepancy in log handling or setting up was removed, each billet was cut into 5 using the same cut pattern on each billet.

Got 3 billets of ironbark, all 2.4m long, all from the same paddock, all within an inch of each other in diameter, all harvested at the same time. Used three new chains to try and keep things as even as possible and used the same powerhead to run all three.

First log, started with the 3/8 chain full compliment on a 24" bar, gave the rakers 2 files fresh from the box. First billet, ripped out 5 post, took 6 mins 01 seconds.
Then used 3/8 chain on 24" bar with every third tooth and raker cut off, (this is what I normally have used for ripping posts) again new chain, rakers 2 file strokes. Second billet, 5 posts ripped took 4 mins 41 seconds.
Then went to .325 chain 16" bar, full comp chain, fresh from box two files on the rakers. Third billet, 5 posts ripped 3 mins 53 seconds.

I worked at one time with a guy running 3/8 set up like yours beside me... Same saws 056 MagII's, same 22 inch solid nose bar... I was running .404 skip.
We raced all the time, he always beat me over a single cut or a given billet or two. But I mostly tallied better at the end of the day: not much, 5 or 10 posts at best. We always put it down to the heavier chain being quicker to sharpen and being able to wear a bit more dirt before the edge gave out.
Ive used a 395 with a 16" bar.... dammed near as fast as a Hagan, and as likely to eat you I reckon. And what's the yellow thing in the background? You been toy shopping again???

John, the yellow thing in the background is Bertha. An old Hyster fork from WWII, she does a good lift - 7t 600mm out from the tower. Its not mine,just being stored down here and I get to use it occasionally.
JD, I just used .325 .058 gauge, it came with all the bits, so I couldn't tell ya. As I've never played with chain that small dunno how to tell the difference.it does have bumper link (which I hate, but can't source it without) on the rakers it has 25 stamped, on the drivelinks it's stamped with 21 - oregon chain.
On Friday, I did a bit more comparing, with a chap who uses .404 chain we ripped out 4 posts each (billets are getting a bit scarce, all my practicing is going through my pile) In proper competition style, and I ended up with my posts ripped out and finished about 25-30 seconds before him. Although he maintains the .404 was quicker in the cuts than the .325, and felt its coz he isn't used to ripping to a point (usually splits them off with wedges) and had to go back and rip through the cuts twice to get the post free. I reckon it was a positive win for .325 chain as obviously he didn't go deep enough with his cuts and so gained a bit of time that way, but overall it was a good bit of fun. I'll have to try get the video uploaded...I love my Lucas!! ...just ask me!

JD, I'm pretty sure its semi chisel, not full chisel, but like I said, I've never used chain this small, so not very sure about its 'name'.
I am thinking about dropping every 5th tooth off to see if that allows me a bit more speed.......I love my Lucas!! ...just ask me!

Interesting exercise. What dia are the logs, and what angle are you holding the saw?
With your mates 404 it would have been interesting if you had used his saw and you had times it, that way it would have been a consistent cut etc. Oh well too late now and with limited stock can't really try everything LOL
Ran into you brother in Canberra, didn't know you were related, small worldNeil____________________________________________Every day presents an opportunity to learn something new

Yeah, a bit difficult to cover every facet of it to give a definitive result on which chain was better. I do suspect that a day using .325 will be a lot easier on the body.
Yeah, the brother is around, but we don't talk to each other, so not surprising ya didn't know we where relatedI love my Lucas!! ...just ask me!
