    Yes they will cut to smaller sizes. I'll often buy Rectangular plates like for Z axis just slightly over size leaving just a finish pass. Less machine time this way.

    Yep, exactly what I need.

    In my case, would you use Mild Steel or Alu for my Z setup? I suspect Mild Steel will be more suitable.

    I've used ASC - good service etc.

    Yes ;)

    Aluminium is much easier to machine...

    Yep, doesnt make it better though :-|

    I could probably weld the plates up to leave the slot for the bearing / ballscrew. My Denford can do mild steel machining without too much of a problem - albeit fairly slow going.

    I'd go with steel if could work with it. However I'd only use it if could do it correctly which means will need heat treating and stress reliefing then grinding in critical places.
    If you can't do this then you may find Ground tooling plate will be more accurate as it's already been heat treated and ground flat.

    Plug welding will allow thinner plate to be used but all the above still applies and will require more work because all that heat will warp and put stresses into the whole assembly. If those are not released carefully then they will release eventually which will make for bad day when you do realise.!!

    I agree with all the points in the previous post, but will also add that the advantages of each material are quite slight, so you might as well pick the easy option and use aluminium.

    Yep, this I cant do at home, so looks to me a limited option for me then.

    Chaz,

    I am about to place an order with Misumi. If you do the leg work and find the part number for the piece you need I will order it for you.
