Wayne (and other interested readers) ... I do a fair amount of bowls and have fantastic results using the Guinevere which can be found here

I got mine from Woodcraft during their initial introduction and it was still rather expensive. For me the expense was definitely worth it.
The unit is great for sanding internal throats of vases and deep into bowls. BTW, it only takes just a few minutes of sanding to finish the job. By hand it would take much, much more time and cussing, and a few skint knuckles, etc.
If you can get to Woodcraft and look the system over, and you do a fair amount of inside sanding you too may find the system very worthwhile and interesting.
One other thing, you can design your own flex cable system from components that are available from Craftsman or even Woodcraft. The only trick here is to ensure that the cable chuck will accept the larger diameter mounting shafts of inflatable bulbs.
I also will tell you that I don't inflate my bulbs at all. The firmness of the sanding collar holds the shape and forms to the cut shape great. Just start sanding ASAP as the sanding collar can fly off due to the high speed of the cable motor.
Start to finish takes me less than five minutes and that includes going through several grades of sandpaper. There is almost always some hand work to be done, but the majority of the hard work is all over with in minutes.
Good luck ...
