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.
