Title: Full skip ripping chain
Post by: casey v on September 21, 2005, 08:14:54 PM
Does the use of a full skip ripping chain require the use of a larger powerhead than a full comp ripping chain? I read somewhere it does, but you would think that with a lesser number of cutter on the full skip would require less power. What are your thoughts on this?

Less teeth= less power necessary, at least that is what my local saw shop says, I agree. Reid

Hi Casey,

if you popped over to the chainsaw forum, the guys who live in there are die hards and would be able to give you a whole swag of info.

For my money like Reid said less teeth for the same length of chain, I would expect less power to be needed.

At the moment I push a chain which has 2 on, 5 off, I've been told that the same length chain can be pushed with more teeth, but to do that the sharpening is done such that it will fly through about 2m of log, but then need re-sharpening and so on, fly like heck, then need re-sharp. All to do with how it's sharpened.

A little above me as I just do what I am told by the manufacturer and leave the R & D to their time and budget rather than mine :D ;D

FWIW I use full comp and a Stihl 066 mag.  Pulls thru a 30" cut without to much more effort than a 24" cut.  I'm to lazy to grind off some teeth and I do all my sharpening on a grinder... I wouldn't want to hand file all those teeth every couple of cuts.

sharpen every couple of cuts?  Whataya mean, they say you only need to sharpen every 8 hours of cutting time.  HA HA HA HA HA. :D ;D

 :D :D :D :D

yeah right,  maybe in debarked pine..... 


In bigger cuts like that in hardwood....  a few cut's at the most and you gotta file/sharpen.  Or be to lazy for that like me and just put on a fresh chain and sharpen them all at the same time some other time. ;)

Less teeth can mean a rougher cut sometimes. One thing that can make a difference in power required  is how much you take off the rakers.
