Homebrew PCBs

I don't really like the dust and noise of saws, and i still need a new  
shaft for my small circular saw (10mm bore).

The only disadvantage of all shears is the edge is relatively rough, even  
some delamination with unsuitable shears.
But having used a expensive bungard shear and seen it produced a  
comparatively bad cut i'm satisfied.

My saw would produce a very clean cut with the carbide blade, but without  
a lathe i have a hard time making a new shaft.
When i have some spare money i'll get material for one, and pullies and a  
belt...

If you are using shears, and see "undercut" (the bottom layers of  
glassfiber beeing cut shorter) then there is a gap between the blades of  
your shear. Tighten the screw on handheld shears or put shims behind the  
lower blade of a lever shear.
