Hi John - you could adopt the (low cost) solution which works for me on a similar sized (midi?) lathe to yours. I find that in a smallish workshop it is vital to have machines which can be moved out of the way or repositioned when not in use.
Basically this method consists of purchasing four braked swivel castors (50mm diameter wheels) each castor with a single threaded attachment hole which matches the existing thread in the base of the lathe stand (typically these will be M8 or M10 on your stand?). These are cheaply available on EBAY.
All you need then are four compatible bolts which can be screwed through the existing threaded holes in the stand and into the threaded holes of the castors. Fit the castors to the stand and simply push the lathe into position in the workshop. The first photo shows the castor bolts screwed
DOWN supporting the lathe in mobile mode.
After positioning the lathe, I either place some breeze-blocks or, as pictured below, some substantial timber battens beneath the stand which thereby maximises the support contact between stand and floor. The bolts on the castors are then screwed
UP so that the stand is lowered and is supported by the breeze-blocks or (as here) the battens. You could use more supports beneath the stand if required.
This method certainly works OK for me!
Hope this may help.
