Is there a noticeable difference between 50cc and 60cc saws?

I like lo pro. I had my 261cm set up with lo pro. I cuts great with an 8t sprocket. I tried the LP on an 026 with the 8t and it was too much for it. My 261 screams with the LP on it but right now I have big boy 3/8 on it since my LP set up is still on the 026. As you probably know there is not a big enough difference between .325 and 3/8 and not much more to 3/8LP to justify buying a new bar, chain, rim sprocket and socket to remove the clutch on a husky to cut firewood like jo191145 was talking about doing.

The 261 cuts good with 3/8 on it.

 

I did a bit of testing on 3/8 lp and .325 with my 421 and with my experience 3/8lp stihl ps on a 50cc saw might just be a fun setup.

 

Good running saw you have there.

Setup right, 3/8 is where it's at for maximum efficiency. For firewood just properly sharpen whatever pitch chain you have and go cut some wood.

8 pin is probably too much for an 026 even with lp chain.

No need to buy a special tool to remove the clutch on a Husqvarna. All you need is a punch an a hammer, that's why the clutch has a cutout on it, even a scrwrench will do in a pinch.

MasterMech Where is the link to your chains test?

 

Think I remember seeing that a while back when Mike turned me on to 63ps. Good write-up and comparison!!

One of the benefits of thinned race chain is the narrowed kerf, which is more or less what I was referring to. The only issue I see with 63PS would be chip clearance do to the hight of the tooth, with longer bars and larger power heads it may become an issue, at least that's what I saw when I was still playing around with race chains.

I'd still like to see what 63ps would do on a bigger saw, it may prove interesting. Problem is getting the right bars and rim.

 

One negative I found with 63ps that I'm running on my little Dolmar421is that it doesn't seem to hold an edge very well. Do any of you have the same issues, or am I just cutting too much dirt?

 

I have a loop of PS3 and it hold a edge well.

 

You could get dansco to make you a rim.

 

Now that you said that, tomorrow I am going to try to get a picco setup on the 441 or 660.

I've had it on the 034S.



I'm pretty sure this was with the 7 pin and PM.

 

Some guys mill with it and get along well.

 

Yeah to save as much wood as possible, but you're not pulling big chips milling.

 

Runs pretty well. Only timing cuts will give a real answer, but I think from just listening to the saw it could have use more gearing, or full size chain.

One way to tell you have chip clearance issues is to stop cutting in the middle of a larger log, and see if you have wood chips packing inbetween the bar rail and chain. If it gets bad enough the chain can totally bind, really common when running long bars 28" and longer. Just something to look for.

Big chips doesn't mean faster either though.

 

Correct!! But that ain't no firewood chain.

 

Gotta practice on something. Might as well be usefull.

 

That's exactly what my saw was doing with the stock chain. One slight wrong move in the cut and it would bog down or stop the chain completely. Mostly seemed to be caused by the chains inability to clear the chips fast enough or chips jamming between the bar and chain,,,, sometimes the nose sprocket. Seemed I had to constantly back the saw out of the cut slightly to allow it to clear itself.
The RS cured that problem for me and it cuts like crazy. I have noticed its rougher running as someone mentioned. I'm quite OK with that. It smoothies out once it's buried.

The other problem was the thin kerf. That might be good for folks cutting cookies off a saw horse but I personally didn't care for it in the woods bucking trees. Never enough warning the bar was about to pinch. RS cuts a wider kerf so I can cut until I see movement.

Yeah I like my 550 just fine. I'll need it this winter so I can't send it out anytime soon. Did the muffler mod (which some people refer to as porting occasionally). Have to wait on the real thing.

 

The 026 ported by Randy Dunlap will pull a 20" 3/8" chain in hardwood quite well. It usually wears a 16" in .325 with a 8 pin and it rips.<iframe width="560" height="315" src="Oh26 20" bar 3/8 chain testing - YouTube" frameborder="0" allowfullscreen></iframe>

 

That would be annoying. Was that with a narrow kerf? I think CoreyB had some issues like that.

 

On the 50 vs 60cc topic, I think most have pretty much said that a 60cc probably isn't worth the cost. BUT, a 64cc Makita bought from Home Depot's rental department probably is. A lot of folks say that saw runs closer to a 70cc saw than a 60cc. But if that's not enough it's easily converted into a 79cc monster!

I run my 550xp until the logs get to 10" or so, then the Makita comes out. I think my little Husqvarna runs pretty darned good, but the Makita runs like a raped ape in comparison, and I've got around $450 invested in it including the p/c upgrade.
