here we have the wood we need to make the blade. so now measure the wood and
mark out 15 inch peice and cut it. it must be wide enough that it doesnt move
about to freely in the tube but not so much that it wont slide.
next we have the plastic that you put electrical wires in to keep them tidy
another pic of the plastic
and my fave tool
now measure the tube and mark out 13 inch peice and cut it
it should look like this
now here is a pics of the blade
now back to the tube, mark a line on the top of the tube
now cut out the line that you marked
you should now have something like this
now slide the blade into the tube and using a pen or marker put a dot on the
blade where you will put a screw to stop it sliding out to far
this is how the screw is placed
this is were you put the screw on the blade
hope this helps, will try and do a better one when i have more time
