You might be better off posting this in 'shop made tools and machines'.

Shopsmith uses a faceplate that mounts on a 5/8" arbor. Tightens with an Allen screw

What John says or you could find an aluminium vee belt pulley, drill some holes through it and screw/bolt on the timber disc. It works. Cheers

woodgears.ca has some shop made machines featured as do the back issues of Shopnotes. youtube has a few vids as well.

I think Woodcraft sells one of those.
