The first addition to my system was a OneWay
look-a-like “V” arm and platform for the 6” wheel. I used ¾”
square tube from Home Depot ($7.50) and with a minimum of welding with
a friend’s help, the 3/8 bolt was in place, the angle was
formed and the platform was built out of ¼” clear Plexiglas.
I laminated (2) 3”x5”
pieces of the plex with instant acrylic solvent, laminated the tang of
the platform and reinforced the tang so that it would withstand downward
pressure from the grinding process. The 3/8” bolt hole was drilled
before laminating the tang into a mortise in the platform.
A piece of sandpaper glued
to the side of the tubing support, around the bolt, adjacent to the tang
minimizes slipping. A 1” dowel spacer was drilled 3/8” and a knob
was created out of ½”
plywood, cutting out three circular shapes on the band saw so as to form
a three star shaped knob. A 3/8” T-nut was fitted to the inside of the
knob into a ¾”
counter-bore 1/8” deep.
The housing for the adjustable grinding platform tube and
“V” arm tube was made out of ¾”
plywood and ¾” poplar. The knob to secure the tubing was made as
before but with a ¼” T-nut mounted inside the ¾” hole before the
pieces were clued together.
