Quartering Logs with chainsaw

[Baron]

Hello All,
I am buying a 660 stihl to quarter many of the large logs that I've been given by local tree services. I want to run them through my Norwood mill and it only handles 29".  The saw that I'm buying has a 36" and 25" bar to go with it . They are both .050. Will I live to regret not going .063?
Also, when quartering these 50-70" x 8-10' logs I'll never be exactly at 90degrees to the grain. You know how it is, you roll around the dogs over and over, so the angle changes unlike when using an alaskan mill. So will a full skip work in this environment or should I stick with 35 degree chisel?

I did a lot of board sawing with my 088 and a alaskan frame before i bought a sawmill. when you go 90degre to the grain you should use 10degree angle chains

Thanks teakwood!
Chisel or round chisel.

I used to split all of the oversize logs for mill I contract to. I used a 660 with Oregon 42 in 63 gauge bar and 75 lgx chain. I had best luck filing at 10 degrees. Oregon offers a ripping chain I have never tried it but I believe the filing angle is around 10 on it as well.

Does anyone ever quarter logs this way (see below)? This method would not require a bar long enough to reach across the whole log, and each cut would have a shorter amount of bar in the wood.

Saw horizontally or vertically lengthwise reaching past the center of the log, but not all the way through.   Then make a cut at right angles to the first cut to free that quarter.    Pull that first quarter off the log.       Now saw again, to free a second quarter.   Then cut the remaining half into the third and fourth quarters.

That is how I will saw when possible. The 25" MS660 is a whole lot nicer than using a 32".

Thanks, can you say why is that and what size logs are you quartering this way?

We have always started by standing at one end and cut all the way through that end, then climbed atop the log and inserted b&c into the cut and sawed across far enough to where the saw could finish the cut from the other end. Hop off the log and cut down that end. If your lucky the log will fall apart, then you can split the 2 halves into quarters. That was always with at least a 42in b&c though, and very big logs. I have quartered some small sycamore with a 24in the same way. These logs ranged from 8 to 14 foot long. Im sure there's other ways to do it and maybe more efficiently but I was just doing it how the mill owner told me to. 10 hour day of it gets hard on the back :D

I am quartering logs up to 65". When I do smaller logs up to approximately 45" I use a shorter 25" bar. At this point, being new to it, I haven't purchased any special chain. I am now, after hearing from others, going to get some full skip, 10*, round chisel.

Be interested in hearing if you find a 10 degree full skip chain.

I am not aware if there is or isn't 10* available. Being new to this and having no instincts to guide me. I was thinking that the operator (me) is supposed to take it from 35* to 10*. But I'd like to hear from others whom have been there.
