Granberg rip chain

[davidbrac]

I have just realised that l can get Granberg rip chain in the UK. I have about 4 years experience in using a standard rip chain at 10 deg angles, but have no experience with the Granberg with its scoring and cleaning cutters.

can anyone give me a run down is it as fact and as clean as stated and is there any problems in use or sharpening l should be aware of?

Thanks

David

I have posted several speed tests for Granberg-style chain. Results were mixed, but in no case was it slower than "regular" 10 degree milling chain.

It behaves similar to skip chain in that it lightens the load on the powerhead and lets it rev faster (about 500 rpm faster).

I haven't run it long enough to draw firm conclusions, but so far it seems to want a more aggressive raker angle on the scoring cutter, for best performance.

Thanks l have now found your thread and read it. I think l will stay away from this chain, at the moment, as there does not seem to be a fast improvement, in relation to the fussiness of sharpening a chain with different angles on the scoring and clearing cutters.

There were actually several threads, with results gradually improving as I learned the best way to sharpen it.

I settled on using the same angle for both the scoring and the clearing cutters. It's simpler and seemed to make no difference.

However, the scoring cutters do want a different raker depth.

I have lots of experience using that sort of chain on 090`s. It is fast and self feeds well but there are some tricks to it, it is important to keep the cutters taller than the cleaners, so you have to file/grind the cleaners back abit before you start using an new chain. We filed the cutters at 10 and 25 and the cleaners at 10 and 10. That would give you a very good self feeding set up, the other thing is there is no need to buy the hi priced ripping chain just make it by cutting the tops of every other pair of teeth with the dremal tool.

Hope that helps
