[QUOTE="Browninglover1, post: 878027, member: 29966"] While this seems true it is incorrect. A hollow tube when heated will expand away from its central axis. When I first started in manufacturing I argued with a machinist of 30 years that heating a tube would shrink the ID. He simply laughed at me and told me to heat it and then measure it and I would see the ID was bigger. He was right it had grown. We used this principle to press fit sleeves onto the ends of shafts for giant mixers. The sleeves were impossible to slip over the ends of the shafts at room temperature, but a little heat would expand the ID and they would slip right on. Once cooled they would be so tight you would almost think they were welded. [/QUOTE]
