Dennis of mafell Nth America reports:

1. As a general rule in oak, a chain should last through at least one average size frame before it needs to be re-sharpened. This could be more or less depending on the number of plunges and the dryness of the wood.

2a. We sharpen chains in our shop.
2b. We have two different sharpening machines here. One of our machines is about 10 years old the other in about a year old.
2c. We got our last sharpening machine from SLYP Machine Fabriek in IJuiden/Holland and paid about $1600 US

We only charge $15 here.

Thank you Dennis
