24" Bar comparison - stihl cannon tsumura sugihara

[mdavlee]

Tsumura makes .050" bars for total in husky mount. Probably stihl mount too in the US. Canada uses .058" and .063" for husky and stihl.

I checked some cannon and Oregon bar grooves when new and cannon was .002-.003" and Oregon was .005-006" bigger than the .063". The chain rides with less side to side pull in a cannon than the Oregon. Never checked a tsumura with feeler gauges.

Redbull, thanks for the info and ordered a Tsumura this evening.

Bumping this up because I'm thinking about a 24" lightweight bar for my 441R-CM... Anybody heard anything about Cannon bringing out a lightweight?

I called them earlier this month, they said its gonna be a while.

I called them earlier this month, they said its gonna be a while.

Then I think I'll try out a Tsumura, although I have had great luck with my Sugi's in 20 and 28 inch (let the 28 go with the 390XP I sold).

 

[Laslabjohn]

I have one and had a few others, they are great bars. Your saw won't feel like the same saw.

Last I heard it will be this spring for the lightweight cannons. Just so you know the Tsumura only comes in .063 for Stihl

 

[Laslabjohn]

Fordf150 has them in .050

 

[Laslabjohn]

But they have the total logo. I just bought a 3/8 .050

Fordf150 has them in .050

In reduced weight?

 

[Laslabjohn]

Yes sir!!

 

[Officer's Match]

[Laslabjohn]

I've yet to see one, even in pic's.

I did measure the bar grooves.
I don't know exactly why the custom bars perform better but my guess is that it could be any of the following...

- grooves are more true
- grooves are cut cleaner
- better metal used

The grooves might be more true, but if the light weight bars flex more it might not matter.

I would think the Cannon would be the tighest tolerances as they are handmade 1 at a time to within .002".

I checked some cannon and Oregon bar grooves when new and cannon was .002-.003" and Oregon was .005-006" bigger than the .063". The chain rides with less side to side pull in a cannon than the Oregon. Never checked a tsumura with feeler gauges.

I saw the bar groove depth was measured, which may play a role, but that's an interesting point about width. I wonder if anyone can take some feeler gauges or a caliper and measure the bar groove width on a Tsumura?

.... . Canada uses .058" and .063" for husky and stihl.

.....

That's the norm, basically anywhere outside certain parts of the US.

This surely is interesting, but we don't know the exact state of the chain or the wood on each cut, so I hardly will call it conclusive.

The tendency is clear though, and confirmed by your other trials!
