Bu88ered up me chain

Recommended Posts

I normally sharpen my Granberg ripping chain at 20` and 0` but in a moment of madness I have done all the cutters at 0`, is it worth redoing or will it still cut until I need to sharpen again..... Fool!!!! check sharpener setting next time!

It should still cut fine.

Seems to be the preferred angle by some, so you may even like it more?

I'd just make a few cuts and see how she goes.

Hi Lazarus,
Cut away with it as it is. It will actually produce a very clean finish, though slower to push through the log. Its a common angle for super hard and exotic woods. Change the angles back at the next sharpening if you need to. I go the other way with my lucas mill slabber, cutting for speed rather than finish, as my clients are paying by the hour ,and will then go on to a secondary finishing of the timber. My angles of choice are 20-25° .
Play with the angles and find what suits you and your most common timbers.
Nothings ever lost when milling

Do you vary hook angles as well?

No I leave hook angles alone and as spec. Mess about with them to any degree and you'll either get a dangerously snatchy chain or one which doesn't barely cut. Also accurate grinding of hook is so very much harder to judge/ measure accurately . Same with depth guages, I leave at spec for machine and chain. Milling chain lengths are expensive enough without amplifying the risk of chain breakage.

Also because I'm cutting so many different types of wood I have to find the best compromise or all rounder set up to achieve good production rates. If I was doing all one species it would be worthwhile tuning the parameters to get the very best performance:quality balance, plus I'd probably still need to keep a number of standard set up chains just for the odd jobs. -Starts to get really expensive then !

Are you guys taking 10 degree ripping chains and grinding/filing them to 0 degrees? 

That's how I started the thread as I c0cked up setting the grinder so not by design.
