John & Gayle,

The Dremel tool I have has an in-built speed control, however could I
suggest an alternative machine when cutting bone and that is a variable
speed SCROLL saw, (Dremel do one but there are many other makes too).  A
large selection of blades are available for these machines from fine blades
which jewellers use to coarse cutters.  The bone would have to be mounted
on a plastic or thin ply-wood base and supported by something like
plasticine if it was small, but larger bones could be cut easily on this
type of saw and certainly much safer to use than a bandsaw.  Prices for
scroll saws vary greatly and it is well worth while searching the market.
