Right heres the general method, had a block of aluminium knocking about the garage, 40mm x 25mm x 20mm (approx) LxWxH so thought I would mount it to the bottom of my side stand, which is OE by the way.
So marked the block and drilled two 5.5mm holes through it, then held this against the bottom of the stand and using an automatic centre punch marked the positions for the threaded holes to be tapped.
Drilled and tapped the bottom of the side stand to accept 5mm bolts.
Next enlarged holes in block to 6.5 mm to half depth so that the allen bolts will sit below the surface.
Assemble the lot and can now leave the bike on its side stand confident that it will still be standing when I return
Hope this is of use to Y'all
