I picked up a vintage Sears D-49 chainsaw for my lumber mill the other day and immediately got it going to see how well it cuts lumber.
This is an 80cc chainsaw from the 1960s made by Sears. It is a direct gear drive. I figure it should be powerful enough to run the chainsaw mill. I have been using my old Homelite SXL Old blue 50cc chainsaw and do not want to burn it up.
Also the old Homelite burns a tank of gas to two 8 inch wide boards which is not efficient at all. And the Homelite cuts about 1 foot per minute on that same board. That is too slow for me.
I was hoping the old Sears would bolt right onto my mill with no modifications. I was also hoping the chain would fit although I plan to get a new chain anyway for this once I know it is going to work.
It took me about 15 minutes to get it mounted because the clutch is on the outside and the drive teeth are on the inside. But I finally got it together. I could use a couple more links in the chain though to make things go easier.
I cut down a tree right next to the lumber mill which I wanted gone anyway. I plan to set up a roof over the mill and lumber drying area before winter. I cut a good sized log out of the tree and moved it over onto the mill.
I got it clamped down and settled where I wanted it. Then I fired up the old chainsaw and started to cut. I noticed that this old saw cuts way faster than the 50cc.
I was able to cut three 10 inch wide boards on a tank of gas and the saw was not hot like the Homelite always was. I figure with smaller 8 inch logs I can get 3.5 to 4 cuts per tank of gas. This is going to be a more efficient chainsaw for my lumber mill.
The old Sears 80cc chainsaw also cuts way faster than the Homelite. I am not sure yet on the time but I can see it cuts so much faster and smoother. I figure with the new chain it is really going to cut nice.
Part of becoming self sufficient is to make our own lumber for projects and a lumber mill will certainly help out here on the homestead a lot.
