Junk Yard Grinder
I inherited an 'antique'
multi-tool type contraption, part grinder - table saw - lathe - drill
press (and who know what else) from my grandfather. So this thing
must be like 50 years old or something, it takes up way too much in my
garage, and I am in need of a 2" x 72" belt grinder, so I'm going to do
some 'field-fabrication' and convert it as best I can. I'm
basically 'winging-it' but am referencing the section in Wayne Goddards
book, the $50 Knife Shop, about building grinders. so here it
here is the assemblage.....the multi-tool and its pieces, the 4" steel
drive wheel purchased from Rob
Frink, 8" and 4" cast iron & polyurethane casters
purchased used from Surplus
Center. And I pallet form the trash pile to scavenge for wood
I determined that the bulk of the waste was length so I shortened up
the steel tubing and wood plank base. Cutting and rewelding
where necessary. Note the base on the left hand side in the pic
above and below. the whole assembly is meant to lift vertical and
tighten down, which I have no use for, so I flipped the base piece when
I reassembled it. I kept the axle/pivot cause that's the only way
you can change the V-belt.
it is with the cut off tubing welded back on for the vertical arm
and with the motor tilted up just to show the action.
finally, then end of the work day today, a mock-up of a potential way
to mount the contact and idler wheels, using wood from the pallet,
bar clamps, and drill bits for the axles (cause the axles that came
the casters weren't long enough....and I just wanted to see how it
looked laid out). I'm gonna do this part drilling and bolting as
Goddard recommends so shimming is possible to aid in alignment.
This orientation so give me plenty of room for a good, long platen and
spot for 'slack belt'.
I have not yet decided on steel or wood for the arms, and have yet to
build the platen assembly and support table for the grind wheel at the
other end f the arbor.
