When you start making your own chains, don't just make one or two.
It takes a little practise to get the tecnique down.
I have a board set up with a nail in one end and marks telling me where to cut for the different bar lenghts we run.
I'll cut a stack of chains first, and then rivet the whole bunch at once. After doing 5 or so, I get the feel for it and it goes really fast.
After my knee operation when I was housebound, I ran through 2½ rolls, so I probably won't have to make any more this season.
It's a great way to spend a rainy day, too. And the sight of 50 boxes of chains on the shelf is nice.
We go through a LOT of chain logging, especially since it has stopped being really cold here in winter, a big hardwood felled on muddy ground eats up o lot more chain, than one felled on frozen ground.
