The entire stand is at a comfortable height for working from a standard chair. I used a 20 liter plastic washing basin as the base for this. The large circular plate was a piece of scrap found on a farm. Once I stripped the paint I found it was actually stainless steel, but any mild steel of at least 3mm thick would do.

The upright is a 70mm tube of 2mm wall thickness. I made the height to suit me seated.

The plate on the press stand tube and the mount-plate on the press are 3mm mild steel. This is rigid enough, a thicker plate just adds weight.

Bolts are 5mm, four of them hold the press to the stand. I used the same size to bolt the press to it's plate.
