   Getting back to the original idea.   
      
   By using a commercial or commercial like welding table as the base:   
   1.  You don't have to make a base plate.   
   2.  You can adjust the distance between the cutting spindle and the tube   
   vise without loosing your angle.   
   3.  The base plate (table) is going to be flatter than the typical bent   
   and welded base plate that comes with many tube notchers.   
   4.  Its an out of the box solution that will produce quality repeatable   
   results without spend half your day cobbling up a makeshift solution.   
      
   I've spent way to much of my mental budget thinking about this, and I   
   have solutions for tables with different dog hole sizes and grid pattern   
   spacing.  To a limited extent even for tables with erratic grid spacing,   
   but maybe not for tables with radically erratic dog hole sizes.  LOL.   
      
   Making the spindle fit multiple tables is easier than making the vise do   
   so, but both are possible.  You still have the same accuracy (more or   
   less) as the grid itself.

   That makes it simple and very adaptable. Optical benches are similar, plates   
   with grids of tapped holes that make positioning easy and precise.   
      
   Having neither I'd consider the mill table as the base. Plates below the   
   sides would align to the tee slot or table edges, coarsely adjustable with   
   parallels as spacers.   
      
   I have a very old horizontal milling machine whose spindle head advances on   
   dovetails, in effect a horizontal boring machine. Unfortunately it has a   
   lever feed table meant for production runs after setup, and lacks any dial   
   graduations. It cuts steel much faster than my vertical mill and the vise   
   swivels in a cutout in the table so it could cut angled fishmouths as-is.   
      
   Grizzly sells a somewhat similar machine that might suggest something you   
   could assemble from parts on hand.

   A lathe milling attachment could cut angled fishmouths on tubing within its   
   vise capacity. I bought an available one for genuine collectible South Bend   
   10L accessory completeness but haven't found much justification for it.
