I usually use this method, with the engine bolted into a test bed made from a cut down Ruby chassis. It's worthwhile examining the crankcase minutely for cracks before you start. I use a 3 foot long, 3/4 drive breaker bar to do the nut up and put my weight on the end of it. (>300ft/lb?)
BTW, it's worthwhile, if you can, to machine out the small end of the tapered hole in the flywheel so it's parallel for about the first 3/16". I've seen cranks digging into the flywheel here and then coming loose on the taper. It's especially a problem on the Phoenix cranks as these are surface hardened - I saw one Phoenix where the small end of the taper had dug in and then broken away in a ring.
