"skip" means pretty much that, there are spaces between the cutters (bits), maybe only half as many bits are on the chain.   The first pic shows what is currently called "full comp" meaning normal compliment of bits. The second pic shows "skip" Modern high rev saws need fewer bits in order to keep the revs up with longer bars, less friction, less of a bite. Our older saws have the type of power to pull a full set of bits without loss of rpms. I used skip on my Super 250, it was somewhat cheaper and I was cutting very soft second growth Redwood, it was filed fairly agressively. |

Now it makes sense. I suppose if you don't have a 3100G to pull 48" .404, using a 3/8 skip on a 903 would be an alternative.
Speaking of long bars and small engines, I suppose setting the rakers at .020 on 3/8 who also help.
In the picture it looks like there is one extra drive link between each cutter.

I reread your last post, and realize that you were speaking hypothetically. But it begs the question, could you do it? and would it work?

I thought I'd use a wire feed and touch each raker then grind it to .020. ;D   Actually I was typing faster than I was thinking. I guess in theory it would be a good idea but I don't see any chain on the market with unground rakers. |
