I've always just turned the brake drum around, screwed on at least 3 nuts a few threads and used it as a slide hammer. I guess I've been lucky, they always came right out. I agree with tacking the axle/bearing. If the reassembly uses the safety collar, I tack it to the axle. If it's just a bearing, I just put three little tacks on the axle itself to keep the bearing from sliding off. The last time I got lazy and had the bearings replaced, they didn't tack them and sure enough the axle came out, the new Coker WW tire hit the fender and self destructed. I had my '31 Tudor behind me on the trailer at the time. Luckily, I got it whoa'd down and off the highway without incident, but it cost me a tow, a tire (twice) and a bunch of time. I'd rather tack 'em.
