Many times a project calls for materials of specific dimensions and quality that can't be obtained, financially or logistically. A chainsaw mill is a tool that can be utilized to produce beams for timber framing or to cut slabs for wood working. Being mobile, it can be on site or right where the tree falls. This instructable shows how to construct a 20 in bar , variable height chainsaw mill.
There is an update
in the mill post section. The post clamps now have bolt pins to secure the mill to the bar.
There are details in the pictures so mouse over the yellow image notes to get a clearer explanation.
Step 1: Measure & Cut
(This is for a 20 in bar) Accounting for the width of the square stock, the diameter of the largest tree that is able to be milled is 14.5 in.
(4) 8 in square stock
(2) 12 in pipe
(1) 3 in wide by 8 in long sheet steel
(4) 2 by .75 by .25 in bar stock
(4) 4 in bolt, (4) nuts, (8) washers , (4) lock washers
(2) 9 in square stock
(2) 14.5 in square stock
(1) 6.6 in square stock
(1) 5 in pipe
(1) 1.25 in square stock
(1) 2.5 in square stock
(2) .5 in nut and bolt
Square stock is (1.25 by 1.25 in)
Pipe is (1 in) outer diameter
