Wong,
In terms of the arbour my choice would be for a 25mm dia bar turned to 20mm to go through the "chuck" with a 16mm threaded bit at the end to take a nut and washer. Centre drilled so that it can be supported by a rotating centre.
Now will you be able to drill a 20mm hole through that piece of steel, and a 16mm die to cut the thread? Do you have a 20mm drill?
