Lighter Touch For Modded Saws???

[rahtreelimbs]

For those of us that run modded saws, one thing has got me thinking. I know that when a saw is ported the torque moves up in the rpm range. On some saws does this seem to mean a lighter, more aware touch is needed to keep the saw cutting fast? I haven't noticed this in any of my modded saws,I cut with a pretty light touch. But not all saws respond the same to porting.

In my limited experience with my two small modded saws (34 and 46cc), I have found that I need a light touch in order to maximize cutting speed. I can still lean on them but not very hard or else I might pull them down out of their powerband. Then it's all over. But with a light touch they simply scream through anything. So therefore I believe it takes a slightly more experienced sawyer to fully appreciate a small modded saw.

I can't say about larger modded saws, ain't there yet.

Thanx Brian, that is the answer that I was looking for.


A few weekends ago Husk288XP and I were working for Geofore. I let Husky288XP try me PP346XP. He was leaning to ####### the saw, I told him to just let it rev.........made all the difference in the world!

If you lay on the modded saw and hold it down in revs, you wont see a lot of improvement in cut times. You got to let them run; the cream is at the top! If you dont run sharp chain you are wasting your money too!

It work very well to have a buddy with a stopwatch stand there and yell times at you while you slice cookies off a log strapped to a stand. I don't mean 5 or 10 cuts, I mean a lot. After a bunch of cuts you'll start to see patterns of what works and what doesn't.
It's very educational.

That is why I stick with the 325 on the 026. Lets the motor stay in the powerband better. Practice will keep you in the powerband and let you cut faster.

Of course if you are running a 400cc Rotax, like Matt Bush, JUST LAY ON IT!

2100

Steve here... In small wood I push as hard as I can on my modded 2100Super. The saw runs in the 11000's in the wood. The time dropped even more when I went from an 8 to a 9 pin. I have not run a ten pin with this ported cylinder. WHen the saw was not ported it could run a 10 but you could not push near as hard, and the tymes went up.

Wouldn't you want to play with your racker hieght so there is max cutting. Ever since I started filing them down way more than average my saws are self feed. I never have to push just use kid gloves.

Marky,
I have to agree with you 100%. I have to file my rakers down alot more than average.
I was using the EHP7900 and thought the chain was getting dull, after further inspection, I lowered the rakers and hold on.
The EHP7900 hit the rev limiter so quick. I do have to make sure the rakers are right and this thing will walk through the wood.

Marky , you are talking like a pro now, it is all in the set-up of the saw , you should be able to run the saw the same if it is ported or not, myself i donot like to push ,i would sooner have the saw work for me than me have to work the saw, now the ported saw is going to hold its rpm's in the wood higher than a stocksaw but with the racker height and gearing you should be able to get the saw to cut for you the way you like to run the a saw and not have to make changes to your style of cutting

Ed made the most sense with his last post, whether or not a saw is modded does not have any bearing on overcutting, always let the saw cut wood, a light pressure, use the dogs to guide the cut. All the time I hear someone in a tree or on the ground over cutting a saw. Keep the chain sharp, riders set and guide the saw thru the cut over torque and you will not be pleased. Operator error.

 

[rahtreelimbs]

I phoned Ken Dunn after I bought Scott Kluges Solo KD651P. Ken stated that he liked to push and thought the saw would run its best with the rakers set at .017-.018". He stated that it all depended on your style. Well my style is to not work any harder than I have to. So pushing doesn't apply here.

 

[rbtree]

If I recall correctly, the no longer availble dyno test results that Walker's did showed that most modded saws (theirs) had a much broader power band, not just at higher rpm, but lower also. That is what I notice with most of my modded saws, that they are not finicky, and will handle lower rpms as well as a stock saw. That is not to say that a saw should be overworked, on the contrary, I agree with everyone here, let the saw do most of the work..as long as the chain is sharp and depth gauges are set correctly.

saw cuts

There are a few mistakes that are common and you can hear them being made when someone else is running a saw. It starts with the guy that sets the bar on the wood then pulls the trigger and the chain hangs on the bark and hesitates to start the cut. Bring the chain up to speed before you touch the wood. Next is the lean on the saw as hard as possible to get the saw to cut through faster and the saw bogs out, when he should have let off the pressure and let the saw do the cutting, the saw should pull itself through the wood if the chain is sharp. The chain moves through the wood at a higher speed and cuts much faster with less push. Backoff and let the saw do the work. The guys that rev the saws up and down, up and down in the cut, when they should be trying to hold a steady chain speed. With a light touch and steady speed you are more apt to feel when you hit a nail, rock or knot in the wood and know when to backoff and check what you hit before you knock the edge over on all the cutters. Just by the sound, you can tell the guy is pushing too hard or needs to wiggle the saw to clear the chips out of a cut in big wood. Untill they cut lots of wood and learn by experience their not going to listen if you suggest they are doing something wrong. They are not going to believe a lighter touch cuts faster. They will be out there trying to push on the saw to get it to cut as fast as they saw you make the cut.

this whole thread is a statement to what i believe to be a fact..learning the saw..
what works is not necessarilly any strit rule that applys to all saws and operators..it goes to the sayin ,some people got 1 yr experience ,10 imes..
others are able to add each yr of experience ,so by ten yrs [example reference only] they are a lot better ,thru learning and adjust so u know how to get the best out of a saw or any tool..
i can do things with tools [ztr mower] for example,that allow me to almost equeal what these newer guys can do with trim man an mow man working togather in the same amount of time..
as to saws ,i didnt really know much about getting the best out ofum until i found this site..its much to be learned here,best learned by working with the tool and trying things learned here..
the ability to think a bit, dont hurt..
anybody thinks everybody knows how the use there brain tool.. just aint tried to hire good help lately..jmo
