circle crank ms660

[huskihl]

Those hard woods are making sparks off the bar and chain. If there's sparks in the chips there's metal in it. Fire a saw up in the dark and it makes all kinds of sparks

Ironwood does that up here. That's about the only one

In the dark you can see why the screen in the muffler is called a spark arrester.

Only things with thorns up here are raspberry bushes....and some women

I'm fairly certain all female homo sapiens have thorns. Some are external and others retractable.

Thorns, fangs, stingers, or whatever, yeah they do have them.

I think wood varies based on where it grows. We don't have live Oak around here, so I can't comment on it.

Ash & Black Locust are VERY HARD, but IMO often cut faster than an old Sugar Maple or a large Oak tree. Shag Bark Hickory ALWAYS seems to slow my saws down.

For me, White Pine (with full comp square file) was like cutting paper mache, much faster than Ash. Silver Maple, Red Maple and even Apple (which is a hard wood) seem to cut very fast for me also. Ash is someplace in the middle. (Note: the Apple was green, dried I think it would be tougher). Black Walnut also seems to cut pretty fast.

I have encountered Black Locust that grew in sandy soil that would make you sharpen your chain every 2 or 3 rounds, but only in one location. Other times, as hard a wood as it is, it was not that tough to cut.

Oak (Red & White) and Hard Maple are the trees I encounter most often that give my saws a workout. Hickory is not nearly as common around here.

River bottom trees will kill chains as well.

I bucked up some river bottom walnut that a buddy brought me it was hell on a chain.

Back to the circle crank experiment........

When you begin porting for the reduced case volume, remember that it will be hard to grind more volume of material out of the transfers, than what was added by the cranks filler material. This gives you an excellent opportunity to enlarge and shape the tunnels to a much greater extent than normal, even if you have to add epoxy to the outside.
A good example of this is the 576xp, 562xp, and maybe some others. They have full circle cranks, and very long, well-aimed transfers taking advantage of the reduced case volume.

 

[Deets066]

There are a lot of options for porting the circle crank, may take a jug or two to figure it out

 

[awol]

Yup, at this moment, the timing remains a mystery!

Ok I'll cut some oak

Now we are talking real saw cutting.

 

[WKEND LUMBERJAK]

Jason that is a nice running saw .

I'm going to build another saw around this crank,the saw I have now runs good enough thar I'm leaving it.

This saw is for sale! Anyone interested?
It's not cheap but it's completely rebuilt and very strong.

Jim that is a nice running saw .

Jason,lol
