Precision Cast Bore, How to remove mandrel when its locked with epoxy?

Hello there,

PLEASE Help,

I want to solve precision bore casting. I have tapered mandrel and bamboo. I will center the mandrel inside of bamboo and fill the gap with epoxy.
If I fill the gap with epoxy on tapered mandrel , How I Would Be Able To Remove The Mandrel from epoxy core ?

Can you help me ? This is very mind confusing problem for me and I need a answer .

Thank you very much,

Best,

Mustafa,

Petroleum jelly (vaseline) applied to the tapered mandrel will lubricate it sufficiently to remove.
