Chain size
« on: July 06, 2015, 10:26:12 PM »
I am switching my chainsaw over to .325 for light milling and I was wondering if anyone knows how many links I would need for a 24 inch oregon power match bar with 9 tooth rim sprocket. (D009 mount)  The bar and .325 tip are in the mail and I would like to get some chain soon.

No luck.  I'm putting the chain on a Makita 6421 and the tool you linked only shows 3/8 and 404 for my saw.  My bar with the 3/8 nose calls for 84 drive links so there might be some way to use that to get an idea for the .325 count on the same bar.

A 3/8 chain in 84DL is 5.14 feet long.
To equal that in .325  a 94DL is 5.12 feet long, a 95DL is 5.17 feet.

I would go with the  95DL if you're running a 9 T .325 rim sprocket.

Thanks a bunch Holmentree!  Do you think I could get away with running 325 nk on that bar so long as I retired the chain earlier than I would with standard 325, or does the 325 nk require specialized bar/rim/nose sprockets like the 3/8 picco does?  Also, would 20lpx(standard 325) and 95vxl(nk325) be the best chains to use to slowly file down to ripping specs?

.325 NK  and  standard  .325 take the same rim a nose sprockets.
Either  chain will work well with milling with a 10 top plate. Trouble  with the NK is when its  cutters are filed back to about 1/2 size , if there's  any extra spread in the bar rails that thick 24" bar will be too thick for the kerf of the NK chain. It will cut poorly.
A NK bar is thinner so the NK chain can be filed back to the witness  marks. You won't  find a 24" NK bar.

The only dl count I have seen for a 24" .325 bar is 92. That is for a Sugihara Pro (not Light) with a small Husky mount, in the UK - but the sprocket size was not specified (which usually means 7-pin).

A 9-pin should make only one dl differense - but then your bar brand and bar mount aren't the same, so hard to say.

This won't be much help, but here's another 24" .325 small Husky mount bar.
http://leftcoastsupplies.com/product/24-gb-pro-top-bar-325-050

I'm interested in this bar, as I have half a dozen large trees that have to come down sooner or later that are a bit much for the 18" bar on my Dolmar 5150.  Is this bar suitable for the job? I realize it's a bit too much bar for routine cutting. Holmen Tree is 500 km away and the mileage would be a bit much.   ;D

     Howdy,
   I just wanted to clarify on the UHL24-50PJ Pro Top bar drive link count. That particular bar was shorter version of the "CJ" "K095" for US made saws like Homelite, and Poulan that ran 80dl, or 81dl of 3/8 pitch. I'm guessing 96.

I wondered about that, as the listing didn't say - but 96 sounds very hight to me, specially if the 3/8 version is 80 or 81?

     Howdy,
   I should have clarified that. I meant 96dl of .325 with a 9 tooth for the bar that originally runs 84dl of 3/8's.

This is what 95 drive links of .325 looks like on a 24" power match bar with .325 nose and a 9 tooth rim sprocket.  Do you think I should take one drive link out and go with 94dl?

It appears the bar is as far forward as the adjusting pin will allow so you need to take one drive link out.

Considering the differense from 3/8" to .325 is only 9 dl in 20", 84 makes sense.

I would go with the  95DL if you're running a 9 T .325 rim sprocket.
I have no experience  with  Dolmar. But from your pic you still have lots of adjustment  left with the 95DL. Looks like the adjuster pin is in the sprocket cover.
In the perfect world  it's  nice to have the tail of the bar as close to the rim sprocket that can
be allowed . But to make the chain a 94DL a cutter will have to be removed leaving a skip
tooth gap

It appears as though he's already got a gap, right near the silver rivets just beyond the power head on the top of the bar, so taking out a link there would get rid of the gap.
