I was able to get a good start on my mounding adapter for the 3-jaw chuck for my new to me weld positioner last night.
Started by machining some T-nuts for mounting the chuck to the weld positioner's turn table. The turn table has four elongated slots spaced 90-degrees apart. I figured I may as well machine some mounting nuts so I could use them for mounting other items if not using the 3-jaw chuck.
Started with a couple pieces of .5" plate by 2" wide.
I snuck up on the dimensions by plunging along the sides to within .005" width and .020" depth.
I then dropped the end mill the final .020" depth and moved in the .005" to my final dimension for a clean up cut, then drilled and tapped some 5/16"-18 holes and removed from the mill vise for deburring.
Next up was to cut some .188" plate to match the size of the turn table. I cut some plate out roughly on the vertical bandsaw before chucking it up in the lathe to turn it to exact size. It needed a purge hole in the center anyways so that was a good place to grab it in the chuck.
Parts completed so far.
Tonight I will drill the mounting holes to mount the plate to the chuck/adapter and then drill the four holes in the plate to attach to the turn table. I will then weld the chuck adapter to the plate and call it done.
