Start sumpin

[Tony Snyder]

Sedanman or Mike, get some crap started. I'm bored. I can't seem to start nuttin.

Why does Stihl use a 13/64" file on 3/8 pitch and Oregon use 7/32"?

You asked for it!

 

[treeclimber165]

I've run Stihl chain for years and NEVER even seen a 13/64 file. 7/32 works great on the 3/8 chisel chain (RS, I believe).

 

[Tony Snyder]

I use 13/64 all the time, easier to get into new chain and makes it a little more aggresive. But I'm usually filling for demo saws, not for durability.

Customers chains I grind on the Silvey.

 

[woodsjunkie]

I use 7/32 for about half of the cutter life then switch to 13/64 works real well for me

 

[rbtree]

I use 7/32 or 13/64 on new chain, and switch to 13/64 or 3/16 for shorter cutters.

13/64 is best if you just use one size. However, it is easy with it to cut a bit too deep and end up with too much point on the cutting corner, which makes the chain too aggressive and can dull easily.

It is usually suggested to tip the file down about 10 degrees, with chisel chain, which increases the possibility of filing into the tie straps, thus another reason for using smaller file sizes.

Been trying a bit of square filing, but it is so hard and time consuming.......


Roger B,

Now with five tuned saws:

Husky 335 XPT Walkerized

Stihl 044 madsen's power tuned
Husky 372 XP " " "

Husky 3120 Greffardized ( 36, 42, 60 inch bars)
Craftsman/Solo 651 Pro Greffardized

 

[WOLF_RIVER_MIKE]

go rbtree! how's that 3120 working out? have you got a chance to use it much?

Who is an expert on square ground? Sure would like to know how to do it correctly.

 

[woodsjunkie]

Me too sure would like some pointers.
Mine cut ok but not as good as they should.

 

[rbtree]

Wolfen:

After getting it back from Dennis, the second cut I made was with the five foot bar in a 70 inch maple butt cut. Dogging in with most of my strength, she still kept spewing huge chips. I did no before/ after tests, but guess it has 30-40 % more power, from 9.3 to now 12-14 hp. No way could I dog it in like that before, even with the 42 inch bar.

However, any napping babies for blocks around probably wake up bawling thanks to me!!

Climbed and felled close to 10000 board feet of maple, cedar, fir in close quarters earlier this week, a few butt cuts with it, some with the tuned 372.

 

[WOLF_RIVER_MIKE]

Wow, Roger, it must be deafening. Got a question. How to estimate the board feet of a log?

 

[Newfie]

Hey Mike,

Couple of different tools to estimate BF in a log. Conway Cleveland makes a log scale which is essentially a cross reference chart on a measuring stick. measure your average diameter inside bark cross reference the diameter w/ the log length and it tells BF. they come in the different scales (Intl.,scribner,doyle). Bailey's and CCD have 'em for $45 or so. They also make a version which can help do the same thing while the tree is still on the stump.

I'm sure there is also probably a formula for the different log scales but math makes my head hurt so I use the rule

 

[Gypo Logger]

Hi there, I sell hardwood logs on the Doyle scale: tip dia. in inches, minus 4, divided by 4, squared, times length. Therefore, a 24" log, 10 feet long scales out at 250 board feet, while an 8" log scales out at 0 board feet. This scale is exponential and beats up on small wood, but is not reflective of yeild when it is sawn into boards, ie, one could realize a 50% over run, however, the sawmill folk wont tell the logger that.

Just thought i would share a pic of my new best bud.

Does it sleep in cedar shavings and eat lettuce?
