Jonathan,
I dont like heating up bearings. I just normally put the shaft in the freezer for a while and yes I used a tube the same diameter as the bearing inner to hammer the shaft in. With a nylon hammer I might add.

You don't have to heat bearings up that much. 100degC is more than enough for installation, and it won't do any damage to the bearing or whatever grease is inside it.
Often sitting them on top of a hot radiator for an hour or so is enough to give that bit vital clearance for easy installation.

Better still do both that way they just slip on sweet.
I find oven on low works good for large items like crankcase's etc . . .We race motoX so with rebuilding engines and forks I get plenty of practice.!!
