The chain saws I make are cut out of a solid block of Pine with my Scroll saw from a pattern by John Polhemus found in the 2003 issue of Creative Woodworks & Crafts. Once the chain is removed from the cut block the fun Sorts!!
You have to use rotary tool with small bits to take the chain apart without braking the links. The handle is cut from a separate piece of Pine.
I make my Chain Saws various sizes by reducing the size of the original pattern.
The smaller you make them the harder it is to make the chain without braking the links.
I have found that the smaller ones sell best.
As always comments and or suggestions are appreciated.
Thanks for looking.
