Moose: i'm not sure how Duckface knows how much you paid for your stand, but i think it's a great improvement over the old one you had that is better for a table or band saw. how much did you pay and you don't have to say? any more pictures to post? it looks fairly new so are you sure it's cast or just steel?
i started a vise and grinder stand thread in the fabrication section if you want a few more ideas on how to mount a few grinders and vises.
If you're trolling for a "You ****". none will be given without details of said CL find. Plus we need a better description of said stand as far as weight, diameter, and height, before a "You ****" will even be considered by the panel of members.
