This is just a simple saw mill that hooks up to a chainsaw and slides along a 2x4. This is not going to be super strong, so its really just for lighter chain saws, such as electric ones. To attache this, you need to drill two holes in your bar matching the two holes on the bracket, ( DRILLING SHOULD NOT DAMAGE BAR IF DONE CORRECTLY).this is a link to a mill that works the same way. https://www.amazon.com/Timber-Tuff-TMW-56-Lumber-Cutting/dp/B01CNRL6TQ/ref=sr_1_4?ie=UTF8&qid=1506344853&sr=8-4&keywords=chainsaw+sawmill. Things you will need: (1) 10mm bolt in width, (2) 6mm bolts in width.

UPDATED!!!

I just uploaded a newer version of the mill that fixes the old problems.

New features:

1.) The mill can now be printed without supports! 2.) The bracket has become easy to attache to the chainsaw bar using the bracket spacer. 3.) bracket spacers are new to this mill, you need to print 4 and place them on both sides of the chainsaw bar inside the bracket.
