Hi Paul,
        One concern I had with this design is the tight edge distance of a 1/4" bolt through a 1/2" wide plate section. I thought you needed a minimum of 1-1/2 diameters or something like that. Am I way off base here? I know that Perry Casson shares my concern and was thinking of getting this part welded to the plate.

Not to worry. There is no load on those 1/4 inch  bolts. Parts are fit together. 
Tab A in Slot B. The bolts are there to take the wiggle out. No need to weld
them but OK if you wish. I try to design things that can be made with just
simple shop tools.
