If that is a bolt together table make sure it doesn't vibrate loose. Great job for your first try. Looks like you took some drafting classes and got an A in engineering.

Jim,
Thank you for the compliments. My metal working experience has been trial and error, but I recently also learned how to use a lathe (thanks to MIT videos on youtube). We had to fire our machinist at work, so now I'm able to fill in when we need replacement parts for molds/machines.
The grinder frame is definitely over-built, but it does not vibrate at all. If I were paying for materials, I would probably have opted for a bit thinner material. As for the mounting platform; it is a bolt together rack from HomeDepot reinforced with 1/2" cherry plywood. This is a temporary mount, but the grinder is held in place by 4- M20 fasteners through 1 full inch of wood. I'm more afraid of it catching on fire than weakening haha.
No drafting classes or engineering under my belt. I really just enjoy making stuff. I haven't made much head-way with the water-jetted machine, but I'm still planning to make a few after things settle down at work... of course, turkey, trout, and morel seasons are here. Too much fun to be had all around. I've only ground out 4 knives on the new grinder, but I use it almost daily for other projects.
