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.
