I agree. I use one of these.

All I need is a hole down the middle to give the hollowing tool a start and
prevent the kick you get from trying to start the cut in end grain.

I'm aiming to make some tall hollow forms and want to start the
hollowing
with a forstner bit. Anyone know where - in the UK- I can get
extensions
for forstner bits (which have 5/16" or 8mm shafts)? The extension bars
for
flat bits don't fit.

TIA

Ian
