Joe's 1000x600x200 steel and aluminium router started

I temporarily bolted a length of rail to the slot, it seems to mount extremely firmly and doesn't move (maybe helped by the very slight V angle it is sitting in) but must be slightly canted as discussed above. Will decide whether to face mill it tomorrow, another option is just to mill a few mm each side of the slot so the rail can sit flat, this would also preserve the 3 planar points (both corners and centre) in case I mess up.

I initially wanted to fix the rail to the centre however this does increase the moment between the Y bearing and the Z plate by 20mm which may counter the increased stiffness from the firmer rail mounting.Then again the centre of this extrusion will be stiffer than either slot as it i supported equally whereas the slots are supported on one side by the unsupported corner. No idea really.

In the mean time I spent at least an hour tapping the ends:
