I finally got time to get the receiver cut into the table. I decided to go thru the top itself.
I cut a square hole just large enough to allow the outside of the receiver to go thru.
I welded a 5/8 nut over the pin hole for a "tightening bolt". Then welded the receiver in place. I left it about 3/16" below the surface. I made a removable plug out of 3/16" steel to cover the opening if nothing is in the receiver.
I used 1/2" thick plate to make the vise mount. Drilled and tapped it for 1/2" bolts.
Welded a 2" tube to the bottom...
Bolted the vise ( My Christmas present
) to the plate....
Also made an anvil out of an old rail..
Next up will be mounts for a grinder and buffer.
