The mystery of the blunt chainsaw

Once upon a time I brought a brand new shiny chainsaw which went swimmingly.
I cleaned and checked it over everytime I used it and made sure it was in tip top shape (or so I thought).

Over time it slowly lost it’s edge, so I would sharpen the chain and re tension it three or four times before I was satisfied with it.
But no matter what I did, or how much attention I gave to that chain, I couldn’t get to back to it’s original sharpness.

Even a new chain didn’t help much.

Then a light bulb came in my head and I thought -what if the chainbar is stuffed?

new ond old chainbar

A quick google search confirmed my suspicions, whereupon I reinstalled the chainbar upside down (it’s typically less worn on the top). -it ran a lot better and cut thru wood like butter just as it had in the old days.

The key problem with the chainbar was the groove that the chain sits in

That 0.26 mm ( 0.01023622 inch ) was the difference between cutting wood like a hot knife through butter or burning your way thru like I was inadvertantly doing.

The winter egg famine

When you have your own egg supply , you  end up trying to match the supply to the demand (not too many, not too much). It’s not something you think about when you live in a town -you just go to the supermarket

We have six chickens which on average give us a good supply of eggs for a family of four.



That ‘average’ can fluctuate wildly..
Typically, chickens moult in autumn and grow new feathers for about a month, there are no eggs while this is happening.
Winter means colder weather, so they tend to spend their energy keeping warm, rather than making eggs.

We had several months with no eggs at all, now we are getting around 4 eggs a day.
