If you can get your hands on a face plate or two, that will be a good option for bowls and platters..........it just takes a little more wood so that you have room to put the screws in and then turn away the holes in finishing off the bottoms. Perhaps a call to your closest wood turning club could get you hooked up with other turners who might have an extra they would not mind you borrowing for a while until you can get your own.

Generally speaking, wood turners are good and generous folks.
