I recently acquired a fisher #4 vise(6-1/4" jaws, 120lbs) and built a new home for it. I used 3/4" thick plate for the top and bottom, 12x12 & 12x18, the legs are 3x4x1/4" tube filled with sand, all that comes to about 230lbs and right about 350lbs with the vise.
Cutting the legs on the Grizz.
"Milling"
1/2" Holes
Marking holes for the top plate.
This is my first big welding project(big for me anyway) my little mig is a little under powered so I did 3 passes, seemed to hold up well and I didn't think my welds were too terrible. "Mind the puddle not the spark" is what I had to keep telling myself. I would have used the stick welder but I have to get a new cord for it.
Just over 50lbs of sand.
The paint is a walnut color, it was still a bit wet and in the sunlight its more brown but in the shop its a nice dark brown not quite black, goes well with the old tools.
The leg had a crappy plate welded to it already so I made a better one. Though I was too much of a noob to remember when I drilled all the holes, these were supposed to line up with threaded holes in the base but I accidently drilled them 1/2" instead of 27/64". These pins hold it really well since there was a lot of down force on the leg anyway after bolting the vise to the top plate.
HEAVY and ready to anchor to the floor! There are 3 holes to use for anchoring, 2 in front and 1 you cant see that is in between the 2 back legs. I wanted a stand that would protect the screws as well, this seems to work.
