The ripping chain myth!

Your trying to find a ripping chain for your chainsaw mill and you realize they are hard to find, well let me tell you that you dont need to go out and look for a special chain. Ripping chains are over rated, just a way to get some extra money out of the average joe.

Ive have run chainsaws as a hand faller on a helicopter logging operation for many years of my life, ive split logs in 2 in the bush many times because the helicopter couldn't lift a full size log, in all that time I have never needed a ripping chain to do the job, I file my saw 3 times a day and it cuts like cheese weather I cut against the grain or with the grain, some times the long string like slivers of sawdust get piled up in the dogs of the saw but its never been a problem.

I say ripping chain is a scam to get more money out of everyone who thinks they need one,"hey are you an idiot, trying to cut that log with regular chain" tell them they are idiots to pay extra for a ripping chain. all you need to do is file the chan with less angle on the tooth 

Normal chain


Ripping chain


And keep the raker as high as possible to prevent the chain from cutting too fast and stalling the saw

Just my two cents

I hate to tell you, but if you are truely cross cutting,
you will not get strings, you will get powder. If you are splitting a 42" log with a 48" bar, you couldn't get any angle other than 90 degrees, and thats how chainsaw mills cut.

I am about to re-grind my first chain for ripping. The original grinding is about 30 degrees. If I file it to les than 10 degrees (other literatures suggest 0 to 5 degrees) the top leeding edge will be level with the depth gauge. I belive it has to be filed down to.030 below the top cutting edge. Am I right or what?

I have used ripping chain on various setups. The chain indeed has a different angle for the cut tooth but every second tooth there is a raker tooth that is ground almost flat that cuts a path for the 10 degree teeth.
The purpose of the ripping chain is to allow the saw to run with less power saving the saw. Also when using a chain saw mill the boards come off with no chain marks like a standard chain. As for costs the rip chains are the same price if not a couple bucks more. If you use a chain saw mill and want your saw to last and your cut to be clean with less planning afterwards you have to use a rip chain.
Try cutting a 36 inch wide cut on a standard chain and your saw will not last very long.
Why do table saws have rip blades and cross cut blades? You can rip with crosscut blade but it will bind and stall the motor more than if you used a rip blade if cutting deep cuts.

get a carbide tip blade and spend mor tim cutting than fileing

Hey,

After reading you post, I took my old chain to the Tractor store where I usually get my chains sharpened. I described your method and they made a rip chain out of my old chain. Thank you so much for saving me hundreds of dollars. It only cost 5.00 to get it made. Thanks Again

You loved her most of all but ceases after the first year or so, she eventually finish looking like the great pussy you married, and if she ditches out with your best friend, she obtains at least half of your belongins. She is the baby of the 6 and she still do like it. I saw Andrea across the room actually looking like someone who had been to a disco, so I walked over and took her picture along with a book about affordable seo . Cassandra had almost as fine a time, playing tennis between Ian and Alex, but
had a panicky moment when she removed her mask to clean it, and started drumming the water with both arms in that way that frightened people do.
Bye

Sometimes it's hard to find the original chain. To re-grind 30 degrees chain - is just the way. I've tried it and my saw cut faster and works not so hard.

comment to the original poster. what kind of logger rips a log in half to reduce the weight large logs bucked into shorter pieces are worth more at the mill than a log that had some yayhoo haphazardly rips down a log. I'm truly baffled what woods boss would let you get away with that and secondly just because something works doesn't mean its the right way. and to the second poster why don't you go out pick up a saw and run it for a while before you tell someone what kind of dust you get from ripping especially when in theory that person has more hours on a saw working for psycho woods bosses the lets him rip logs in half some chains do put out long strings when ripping so until you go out and cut all species with all chain options don't be such a know it all or everyone reading this will be as dumb and the dumbest person writing this stuff.

You would rip the log in half when it is bucked to the shortest length, I would only rip logs in half if they were 8 foot and still weigh more than the helicopter could lift

Getting strings means that you are not truely ripping, but you are probably gravity feeding the saw vertically through the log while standing at one end, then.. standind at the other end you can do the same again while trying to line up the bar nose with the first cut. The bar needs to be half the length of the log so only short logs can be done reasonably accurately, and wedges can be used to finish by splitting any remainder.

Anonymous I hate being the one to tell you you are wrong. Japanese, Chinese, and Korean sorts call for 13'10" logs. Logs such as Sitka Spruce have to be ripped for helicopter weight. They'd rather have halved or quartered 13'10"s than a friggin 8 footer they can't use.
Maybe you should get some experience with big timber, then make your comments on this board.

If your getting long strings, then you are cutting almost with the grain, if you are cutting across, you will get powder with a standard crosscut 30 degree chain. And across I mean lay the bar straight across a stump and cut straight down. If your bar tip is pointing at the ground maybe 30 degrees from verticle then you will spit out some long strips. I proved it this weekend cutting some chairs into Pine stumps for my kids in my yard with my Husky 288.
