Remember your rakers are the important part, it doesn’t matter if every tooth is a different length so long as the rakers are set [emoji106]

Interesting I’ve heard this many times but I hate it personally, if you keep teeth that uneven by the end of the chain you will be missing some.. it just keeps things simple as well if the teeth are the same then the same number of strokes for each raker is needed and you won’t have to measure and set them individually.

I dont think thats good advice at all but hey ho.

 

And if anyone is thinking of getting a Granberg Sharpener they can set the Rakers to the correct depth too.

Cheers for replys, 

 

Chain sharpens with granberg

 

cut started again from the other end because it come to a stop in the cut almost felt like the mill frame was hitting something, but not.

 

Wedges put in after so I could make a severence cut with a different saw

I really think this is an issue with that part of the timber rather than the chain/ mill. I just don't know how to fix it

Ok .... I have never had an issue with tension when milling ash but larch on a band saw can be a pita if not saw log quality .... any photos of the log end to see the ring growth? would be interesting to see a photo of your chain cutters from a top view to.. unless as bill says there is an almighty knot and even then that will only slow the mill down the only other thing would be Stone or metal and that would destroy your chain.

I will see if I can grab a few pics tonight. Thanks

Good to know. I always look after mine anyway so its never been an issue. But Ive always been told that the teeth set to the right depth each side is the most important. 

[Gerbutt]

Yeah when I did my courses years ago I was told that all teeth had to be the same size, so if you hit some metal with a new chain and badly hit five teeth, you had to take all the others down to the same size once sharpened. I don’t know why they teach that cos if you get a new chain and take one side down to half and set the rakers then it’ll still cut straight. Of course all that goes out the window if you don’t keep your rails level and flat ?
