Two hefty pieces of flat bar, one with bolt holes in, 2 or 3 ideally, Piece of 50 mm round bar, and a piece of heavy wall tube with a few nuts welded to it over some clearance holes.
The top piece of bar wants drilling to 5 mm depth with a 10 mm drill bit or some such, all over it. that's the tedious bit.
All sizes don't really matter, whatever is to hand!
I just bought a mag drill. :-) The air drill is a useful thing, but it is slow for drilling the likes of rivet holes, handy for anything over 75mm deep. :-)
