How does chainsaw chain actually work??

[Rob D]

Why tweak it, if it ain't broke don't fix it.....

 

 

Not looking to debate the rational for asking the question just for helpful posts that might help answer it.

Personally I don't think the cutter pivot as there's to much tension on the chain when the saws cutting. But i've never really thought that hard, wonder if my mate who does a lot of photography can do slow mo stuff so we could see....... but how would you get a picture of the chain cutting unless you could shave a kerfs width of the end of a log? will ask but i suspect the kinda chain speeds were talking your goin gto need some serious high tech kit.............

 

Good thoughts Rob, will look forward to some sensible answers coming forward in this thread!

High tech isn't the word, ther a short vid of chain cutting on YouTube, 1400 fps, and it is no were near slow enough.

 

I thought about it and you would be shaving the log to do it, this would require a well held log and a supported saw, don't think holding by hand would be good enough.

 

If anyone got the kit to record there is no reason why it can't be done.

Try this one, closest I've found so far

its like an inverted carpenters plane /plough share The chip comes out he curved hollowed side of the saw tooth.,or more crudely scratching your finger nail through a soft substance.

 

The saw chain was devised after somebody studied a cockchafer beetle mandibles cutting action,hope this helps (if you have time to watch cockchafer beetles,if not take one saw tooth clamp it in molegrip jaws and pull it through a piece of soft woo. (sharpen the toot h 1st!

hope this helps?

It works just the same as a plane but with a side cutter

 

The point of the tooth and side plate cut the grain allowing the top plate or blade in the case of a plain, to take a shaving of which the thickness is regulated by the depth gauges.

 

The tooth is taking a shaving off for the full length of the cut, but there is only so much room to store the waste or shaving hence jamming can occur in longer cuts

would be good to see one cutting through a lump of perspex or similar using a very high speed camera!

Hence when running long bars skip chain is better as there is less cutting per set length of chain so less chance of it all blocking up and therefore the chain keeps going at a decent speed. 50% cutting capacity at full speed is better than 100% cutting capacity when stopped.

i have some dvd's and cd's you can borrow, you only had to ask !

 

back down your way in a couple of weeks
