I watched the video and found it to be an interesting concept. My question is, there is no option for different size chains or pitch. Does that mean the file is a "One Size Fits All"?????Here is something I have been wanting to try out.

Watch the video.
I also want to try a skip tooth and 1/2 tooth skip chain.
The 1/2 skip tooth is maybe called something else but the object is to have a tooth that has been narrowed so it only cuts 1/2 the width and then a full width tooth follows that but only needs to cut the other 1/2.
It is also a skip tooth though.
Supposed to cross cut much better (Make slabs) and running a longer bar for wider slabs requires more power and the skip tooth helps out the smaller saws when a long bar is needed.
Of course my MS250 has oil and muffler mods done to it.
Amazing what some muffler mods do to 2 stroke engines.
Btw, I use a dremel type tool and then do a finishing touch with a hand file.
