skip chain, pro's and cons

[Stubby]

Full skip chain has a Rh cutter then a driver , then another driver , them a Lh cutter etc etc . Semi skip has The same arrangement but alternates between 2 drivers then 1 driver then 2 etc etc .

 

Here is full skip

From personal experience, it does allow you to run a longer bar as there is less 'bite' from having fewer teeth in contact at any one time. A longer bar has more friction anyway, so the increase isn't huge, and if it exceeds design length you can run out of oiling capacity, but it allows you to step up a bit without bogging down.

I tried square ground skip tooth, and did not notice any faster cutting. It was also an absolute git to sharpen.

A skip tooth low pro I reckon would be the way forward if such a thing exists, and be much easier to sharpen.

Less teeth to sharpen and cuts as fast or faster on 25" and up bars.

Cuts hardwood just as good as it performs in softwood.

 

Full skip chatters more bore cutting. Grabs more while limbing.

 

Square ground cuts faster but is slower to sharpen. Also takes a special style grinder that no one makes anymore. Silvey and Simington were both closed last I knew.

 

I have been running semi skip square on a 390xp 25" bar cutting some Red oak, worked well around the same number of teeth to file as full comp 20". First time you rock it a little switch it to round file.

Ok I'll admit it, I don't know what "skip chain" is.

Ok, easy to remember, it "skips" a link.

you can get full skip square ground off rob d on chainsaw bars only has it in .404/.063 though, not an easy chain to hand file though, think it would take a lot of practice
