To answer your question, grounding off the pots has been a standard practice for years, so it is a viable path to take. Be careful soldering multiple wires to your pots...extended exposure to high heat can do bad things to them.
Proper shielding and star grounding does have it's advantages.
Are there specific areas that are giving you grief with wiring your project?
"Fascism should rightly be called Corporatism, as it is the merger of corporate and government power." - Benito Mussolini
"When fascism comes to America, it will be wrapped in the flag and carrying the cross." - Sinclair Lewis (1935)
"History, in general, only informs us of what bad government is." - Thomas Jefferson
“Be yourself; everyone else is already taken.” - Oscar Wilde
I can't imagine why you would actually want the hassle of trying to collect your ground wires on a pot case anyway. Any convenient lug which connects to the output jack's sleeve, or even the jack sleeve lug itself, make much better places for star grounding. Unless, of course, you're implementing the protection cap from QTB.
A metal tab around a plastic shaft will not accomplish grounding the plastic pot case itself. The point of grounding the pot cases is mostly for shielding of the innards thereof, and is mostly obviated by installing the pot itself inside a shielded enclosure. So you are shielding the control cavity, right?

The shaft of the pot is metal only the case is plastic so i guess i could solder to the lug nut As D2o showed. The cavity is already shielded with the black paint stuff, i've even got a couple of tubs of it somewhere thats for another project though
I think i understand star grounding, its where everything goes to a single ground instead of it being daisy chained along to the ground?
either way i'll be doing it tomorrow so i'll get back to you if its worked or not but i am confident i've got it sussed out now
