Alternate work holding methods.
Coffenup raised the matter of using bowl jaws to reverse and hold items for finishing. There are about as many ways to hold and to reverse a work piece as there are turners but I like to crossover between the face plate only brigade and the chucks only mob and use a range of hybrid options.
Most modern turners forget that turners a couple of centuries back were turning quite intricate pieces with out scroll chucks. So it really is a great skill to learn to safely use jamb chucks and non scroll chuck work holding methods.
One handy tip is to have a series of already prepared discs with tenons cut to match your preferred chuck jaws in a range of sizes. Then its only a matter of inserting them into the chuck, facing off and glueing them on as a chuck tennon to a blank you don't want to waste or cutting a recess for a jamb chuck when you require one. I have made up a series from Tas Oak, radiata pine, rubber wood etc and my favourites for the small lathe with kwilia face plates approx 40mm thick x 75mm dia, some with 1"x8 black nuts set into the rear, that I glue (hot melt or Titebond / AVXL Plus) sacrificial radiata pine face plates onto. When the pine is past its use by date face off and glue on another. Using these waste tennons and spacer blocks also give you more room to safely manoveure around the back of the bowl if you like to do pull / shear cuts.
These small temporary tennons, face plates and jamb chucks are really versatile. When used with a scroll chuck they really open up your options, but you must use tennons with sufficient surface area for strength and for sound glue joints to be formed.
