20" Narrow Kerf Bars for 50cc Saws

[JimmyT]

All 3 bars are 20" .325 pitch and 50 gauge They were weighed on a household kitchen scale so the weights could be off just a touch. If you have a narrow kerf Stihl,Husqvarna or Sugihara Bar please post their weights.
Cannon CSM-C1-20-50---34 oz.
Woodland Pro WPNK 20 UM50---27 oz.
Oregon Speedcut 200TXLBK095---22oz.

 

[Franny K]

What does the width of the three measure? Oregon and Husqvarna seem to be about 0.155" for the NK and 0.175 for the lpx, bpx type of chain in 0.050.

Right now my vote is cast for the Oregon Speedcut Bar even though the Cannon will outlast it.

I would get the Sugihara VH2U-0J50HV

I would get the Stihl Light 04, 3003 008 3321/s

Dave, just found this post Jun 28, 2018 — The Sugi bar was recommended over the Oregon narrow gauge because it's less fragile. Does Tsumura make a narrow kerf?

Franny, I'm looking for the Cannon width https://www.cannonbar.com/product/csm-c1-20-50-2/
Boy that Cannon is heavy but it has got some tough steel in it.

I just bought 6 Oregon Speedcut Bars for $28 each on ebay and I just read the label
Made in China

Franny, I put a crescent wrench on the Cannon bar then ran it down tight then slipped a drill bit in the crescent jaws to get the Cannon Bar width. It is 11/64" dead on. Both the Woodland Pro and Oregon Speedcut Bars are 9/64"

that is 0.140 and 0.171

https://www.cannonbar.com/product/csm-c1-20-50-2/ They are calling it NK. It is for 81dl like the replaceable nose solid bars 24" 72dl in 3/8. Hard nose bars can be thinner than the solid replaceable nose bars.

I knew that 1/8" was .125 but had to use my calculator on the others. If I had a mic I'm betting the Cannon is .175 I know the Oregon is not as durable as the Cannon but it is a pleasure to cut with when you are pushing 75 years old.

Franny K. got you an update, just had a neighbor stop by and he had an old mechanical dial caliper in his toolbox. He got a .147 reading on Woodland Pro and a .152 reading on the Oregon Speedcut.

What model saw are you running? I ran some LP's on some small Echos years ago while topping and limbing.

Does the Woodland pro have an 11 tooth nose? I have a 72 dl one and I always count 11 where the catalog said something else.

Just marked mine with a sharpie and counted 11 teeth on the sprocket. I had these Woodland Pro for 10 or 12 years. Nik Bailey (Baileys Logging Supply) would put them on sale every July.

The total length of the Woodland Pro and Oregon is 22 1/2" The Cannon is 23 1/2"

The .375 pitch has 72 drive links on the 20" bar
The .325 pitch has 78 drive links on the 20" NK bar

72 dl is 18" called length for non Stihl in .325. it takes 81dl to make the same size loop as 72 in 3/8. as in replaceable nose or hard nose.

Oregon has 95txl, Husqvarna has sp33g or something close to that and Stihl has the 3690 23rspro. All somewhat redesigned from the h30/Oregon equilivent.
