Also the column is tapped and bolts down from underneath so not sure how id get around that one.

Bertie, if it's too heavy, that's that. But if not, you can screw waxed dowels over the holes on the inside as cores to prevent the fill from coverng the tapped hole. You can knock those out after cure. Taper them to make it easier.

Guys the only reason my thumb up for a resin solution is that you get a natural adhesion to boot so no need for extra bracing and fixings. I worked in the flooring industry many years ago dealing with all types of concretes, resins and aggregates. Like all mixes it all depends on how much air is excluded to decide how porous the material is. The filler material will really be the deciding factor plus any reinforcing if required like a square of welded mesh, cost wise (UK) two pack resin vs cement would be very little in it.
The piece that is missing you could just box in so the resin mix fills that. A bit of bondo afterwards and a sand/ paint and your done.

well iv got it bolted down on the flat plate and started re-assembly.
actually quite like it at the lower height, only issue so far is that the knee handle hits the lower tray when the knee is at the lower 2 inches or so, can live with that for now as I doubt ill need it that low down often.
the straightened screw seems to be working well, is a little tight in the middle but not excessive. and will do for now

and its alive!!
spent some more time today putting the table on then reassembling the head.
wired up a temp lead direct to the motor as I didn't like the standard wiring, luckily it spun the right way first time! :zap:
that's about all I can do for now, don't have any tooling or a proper vice.

Looking good!
How thick is the base plate?
If it's at all flexible you may have problems in that the table might move relative to the cutter when actually cutting metal! If you're not going to reinstate the original base a piece of 20 or 25mm plate (or a piece of substantial channel section) under the column and extending to the nut would help.
Cheers.
Phil.
