I'm not sure off the top of my head, but if you twat out a bearing by twatting the axle, you'll need to put said axle back in before twatting in the second bearing, the old bearings make reasonable drifts, but can get a bit stuck depending on the hub design, so maybe use them to get things in straight but pause before they go into the hub shell and find something else to finish the twatting.
