Thoughts

Just a few quick thoughts. You might look at McMaster-Carr for flat ground stock. There are several choices. You would have to drill and tap for your vise ext. as welding would warp the flat ground stock. The radii can be milled. I can check with my local machinist to see if this would be cheaper than welding, flat grinding, and chamfering a regular piece of steel. I cannot remember if he does flat grinding. One thing that needs to be decided are the "spot on" tolerances you need.
I am in Northwest Arkansas and if you want me to look into this, it will be Monday night before I can contact the machinist. I will also provide a CAD drawing for you if you want one.
