It is said that necessity is the mother of invention. In my case it is
frustration. Getting folder parts flat and parallel is a pain on most days,
adding blades and springs makes it worse.
This is the plan I made:
The spindle has a reverse thread. I used one from a rubber sanding disk.
The disk I junked as it is quite useless on the best of days, replacing it
with a piece of MDF (Supawood)
I recessed the bottom of the disk for the washer to fit.
I moved the depth control nut on my drill press to below the
steel tab.
I use repositionable spray adhesive to hold wet and dry sand
paper to the disk. My knife parts are glued to a steel disk using CA
adhesive. (I first sanded the disk on both sides using this setup to make
sure that it is flat and parallel.)
Turning the nut lowers the disk to compensate for the steel
and paper being worn away.
The result of a few minutes of sanding with 180grit paper.
Soaking the parts with acetone loosens the adhesive.
