It should also be obvious that removing the axle and having the work done safely may have considerable merit. When you talk about rocketing things off a gargage floor you may want to consider alternatives. Home made tools are exactly that home made and carry inherent risks from any standpoint. If you are that far into a rebuild and you are not removing the axle/u-bolts now some 55-60 years old again it begs the question why, you can buy a whole new set of 4 for $32 bucks, anybody price dental work or surgery lately?
