Plate Grinding

[Keith Roberts]

Just your basic 4 or 6 inch grinder. Sears has them for about $50. You can
cut a notch with it. Not too good at feathering but that's what files are
for. Some blades for a sawzall will work on cast iron. If you just want to
slice something, put an abrasive saw blade in a circular saw. This will cut
through any metal. All thread rod, cast iron pipe, plate steel, rebar, etc.
and deburr the threads on the side of the blade. Always use a 7 1/4" worm
drive saw such as a Skilsaw Model 77 with the diamond shaped arbor. If what
you have is minor, you can get away with using the homeowner model circular
saw where the blade bolts right on the end of the motor shaft but it won't
do anything heavy duty. You find out right away why they don't put the
diamond shaped arbor on those saws. These saws can be dangerous when used in
this manner. Be careful. Face protection.
