I hit send by mistake before I was done writing...

There is a radius on the block where the rope enters the metal block. However,
at the junction of the block and the cylinder, both are left sharp edged. I
don't recall, but the cylinder may be bored out on the inside so there is
effectively a cutting edge.

This should work fine with spectra. I don't think an electrically heated blade
is the way to go because it takes time to heat the blade. When you want to use
a guillotine, you want to use it NOW!

Here is a design that one of my friends designed tfor our club winch.
The
beauty of this design is that there is no chance of getting a finger cut
and it
works perfectly.

The design is based on a rotating cylinder mounted inside a metal cube.
The
metal cube has a hole drilled through it through the center line. The
cylinder
also has a hole drilled through it. In normal use, the hole in the cube
lines
up with the holein the cylinder. To activate, a handle rotates the
cylinder,
which the cylinder rotatesImagine an 8 inch square solid metal cube.

Spectra can be tough to cut. Are they using this design
with Spectra?

Spectra cuts OK with a sharp edge but blunt steel cutters may have a problem
with it.

The stuff melts below 300F so the people who work with it regularly use hot
blade knives to cut it. It shouldn't be too hard to make a guillotine with
an electrically heated blade.
