what is the most common angle for someone that is ripping a log with a chain saw.
i get some larger logs at times and quarter them with my saw before i put them on the mill. i have alot of the time just used my regular chain, at one time i had a chain that i had sharpened to almost 90 degrees that i would put on to rip with.
just wondering if there was an angle that works best.

Chain that is designed to rip saw is available from the on-line saw supply distributors.  You may be able to find it at a good chainsaw dealer, but not many carry loops.  Some may have a roll of rip chain, to make the loops to order.  You will be pleased with the increased performance of rip chain.  Keep your regular chains sharp for cross-cuts.  Regards, Clark

I find that regular chain actually rips faster but ripping chain produces a smoother cut. Cutting goes a lot faster if you can use a long bar and cut at an angle not directly attacking the end grain, you know the angle that produces those long slivers of shavings that eventually clog your saw.

i sharpen mine at 5 deg on my mill

0 to 5 deg.  When I got my ripping chain new, it was at about 5 deg maybe 10 at most, It cut well, but when I sharpened it I went straight across (0 deg.), and it makes a smoother board, cutting speed seems about the same, maybe a tad slower.  For freehand quartering, I would just use a full skip chisel tooth chain for a faster job.

most milling chain manufacturers grind their chain to 10 deg.  as others have said the closer you get to 0 deg (or 90 deg depending on how you look at it) the smoother the cut.  i mill at 10 deg (woodland pro chain) and like it alot.  compared to using standard cross cutting chain it produces a much much smoother surface.  i've not done timed cuts but i didn't notice a huge slowdown with the milling chain.
good luck

Kcwoodbutcher is correct. I have ripped thousands of feet of logs with a chainsaw and regular chain cuts faster just not as smooth of a finish as ripping chain. If you are just breaking down large logs to fit on the mill I would use regular chain.

I used to make my own ripping chain by re-grinding a standard chain.

- File straight across (right angles to the bar).
- Keep the file level (don't file upward toward the chain).
- File deeper into the gullet so there is a lot more hook on the tooth.

This always cut faster than regular chain.

For ripping big logs,  I'm about to try a "skip-tooth" chain.  Additional raking gets more important to keep the kerf clean.

all i am doing is quartering a big log to fit on the bandmill. it is a sycamore that i hope is spalted, i have a ms 360 with a 24 inch bar, so i am in no hurry on the ripping. smoothness does not matter at all.

I run a 5 degree angled grind on the two bars(36" and 54") I use for ripping those big logs. As others have previously posted, you can rip with either design. On smaller diameter pieces, I've had just as smooth with regular chiseled chain.

skip tooth ripping chains great for falling stringy bark because it has time to clean its self out were normal clogs up and you have to take it off and clean it out

weisyboy

for just quatering its like post splitting.

you want a big saw, with a bar about 40% longet than half the log (if that makes sense). chain ground to standard 25 deg or up to 40, low rakers and hangon.

Ripping a full 24" is asking a lot of a ms360

I use the skip tooth chain on a 48" bar with a ms660 and it does fine. I ripped a 48" dia. 16' red oak last week in just over a tank of gas. I file the chain to the regular 20-25 degree angle and let it rip. I have tried the ripping chain and found it slower but smoother as stated above. It will help to have a few wedges on hand to keep the cut open. With practice you get better at it.
