I've also used a socket before wrapped up to drive the races home, can't remember the size of the socket though, the big one

That's what I used. I put the end that the drive fits into, on the race, so it fits in side it, and gently tapped it home with a rubber mallet.

Nope, the mythbusters I saw disproved the hammer chipping theory, well I think they managed it but only by hitting the hammers so hard the shafts bent or broke.

If you've got to hit the bearing in that hard that you risk shattering it then theres a problem.

I remember that Mythbusters episode. I think the only hammers that chipped for them were the ones that were intentionally selected with pre-existing damage.

The bottom line is that you want to limit your striking or driving to the end of the race and never hit the surface where the rollers operate. Where a drift is used, you want a material significantly softer than the race. If you use a race as a drift, make sure its outside diameter has been reduced a bit so it will not become "stuck" in the hub.

I can't remember the size of the socket now that I used and I'm feeling too lazy to go to the garage to find out, I didn't put it inside the bearing race though, I kept mine flat as it stayed nicely around the bearing race rim and away from the inside surface and was easier to hit aswell

I had an idea.

I've got the old bearing race which I linished down so it slides in and out of the hub easily. I'm going to lay it on some plastic and run a stanley knife round it giving me a plastic disk which I can put between the old race and the new race to prevent damage.

Think that should solve all the issues!

Yes...... except for the very dangerous sharp knife of course..

Yes, putting in outer races must be drifted with a softer material such as brass, bronze or ally. Otherise you can stress the metal. Also, when putting bearings in, they are packed in matched sets, so use the outer race with the bearing it is packed with.
Always good practise if it is OTT to others. Gentle taps at opposite sides working in a circular motion will ensure the race goes in squarely.
