The top of my workbench is a hollow-core closet door from the mobile home I lived in before I bought my house. The frame is 2x4 boards that were the frame of one of the couches I had back then. I was trying to bend 2 pieces of steel plate in the vise last year and when my 2# ball peen hammer wouldn't do the job, I tried smacking it around with a 12# sledge hammer. The top of the bench broke and caved in and the vise broke in half. Inside the base was a part the 2 screws go into, to lock and unlock it so you can swivel it around. That's what broke. My vise is somewhat similar to the one in this picture. It has 2 pairs of jaws, one flat and one for holding pipes, plus more jaws on the very bottom, and the whole thing spins 360 degrees on its horizontal axis. I'm going to bolt it directly to the bench without the swivel part of the base. I thought about making a piece to go inside the base to thread the 2 screws in, maybe from those pieces of steel plate, so I could still have it facing the front, side, or corner of the bench, or any other direction. But It's just going to be facing the front.
I already had a 12"x12" piece of 3/4" thick plywood attached to the underside of the bench top in that corner. Today I looked around for scraps of wood to reinforce the top. I had 1 2x4 about 25 1/2" long, so I cut it into thirds. I squirted Goop into the biggest dents and holes in the bench top, then brushed all the Elmer's glue I had to cover an 8+" square in the corner. I brushed glue on the edges of the 2x4s where they butted against one another and screwed them down with 3" drywall screws. I brushed glue that seeped out the sides on top of the 2x4s and screwed a 3/16" scrap of plywood on top to level out the surface. I did that without cutting the plywood to fit or square it up. I had a triangle shaped piece of good 5/16" plywood big enough to cut a 6" square out of. I beveled the edges and corners with my sander, brushed some Goop on the back of it and screwed it down on the other scrap of plywood. The part of the vise I'm able to reuse is 5 1/2" in diameter, an inch less than the swivel base. That part, seen in the third pic is going in the recycle bin when I'm sure I won't be using it for anything.
I painted the whole mess and will drill 2 holes through the whole stack and bench top, including the 3/4" plywood on the bottom. I'll have to buy a couple of 1/2" bolts 6" long to bolt it all together through the holes where the T-handles to tighten the swivel base used to be (yellow arrow in picture). I'll have to buy hex nuts, flat washers, and lock washers to secure it. After that I need to sweep the floor and slide the bench back to where it was before I started hammering on those steel plates. And clean out my tool boxes, fill them with the tools that are piled on the bench or still lying on the floor where they fell, brush off the bench and slap a little more paint on it, before I can put my tool boxes and trays back on the bench. Then when I have everything back as close to normal as it's going to get, I'll finally be ready to start working on my guns again.
I have plans for a new workbench from Norm Abram of The New Yankee Workshop, but I might wait and see if I'll be moving or not. Hopefully my inheritance will be enough to get me out of this ghetto city. Williams Cheese Factory Outlet in Linwood is only 60 miles north of here. If I lived around there instead of here, I'd be a lot happier. And when I went up north to ride my ATV with my friends, I'd be already be halfway there. If I end up moving, I'd rather not have to haul a big, heavy workbench around.
