How to waste an afternoon

Trying to turn a piece of actual with a tube in it.  The walls flex too much to get a solid grip on a slippery material like acetal.  I have done this stupid before and forgot.

Acetal is so flexible and slippery that once you have drilled a hole down the middle, the lathe chuck cannot get a solid grip because the outer part of the tube flexes under clamping force. I will cut the exterior down to size before drilling and boring the holes. If that doesn't work, aluminum.
