When re-sleeving cylinders on motorcycles, we used to stick the sleeve in the
freezer overnight and heat the cylinder to 400 degrees.

Yup.

Didn't have an oven in the shop, so ring gear supports went into the
freezer and the gears got heated on a steel worktop with a rosebud
torch tip until saliva sizzled on your finger like a hot iron used on
cotton/linen.

Just enuff of the ring gear hanging over the edge of the bench to grab
it with a pair of pliers and plop it on the support. Helpful if you've
got someone standing by with a couple more pairs to hold the ring gear
firmly down against the flange while it's cooling.
