Sander attachment input wanted

[blindhogg]

Well I just recently finished creating a two wheeled flat platten (2 in wheel and 4 in wheel) attachment for my KMG clone sander. After finishing it I realized a couple of ways I could have possibly made it better. So I cadded this up this afternoon. Does this look do-able, or am I going to make it and see a whole bunch of hidden flaws. Thanks for any input you might have.

that looks very do-able to me.Heck while your at it why not make two of them and send me one

I drew up one of those a few months ago too, except mine was like a rotary platen from rob frink with the rubber belt, which adds the problem of tensioning the belt.

Maybe have only 3 wheels and have one of the platen idlers the small wheel?
