any secrets or special tools for replacing the brake drum rivets?
Only suggestion I have would be to either remove and replace one rivet at a time, or remove all the old and bolt up all the holes tight but one, the one you are riveting, then remove one bolt at a time as you continue. After you've done the job, turn the end with the peened ends on a lathe to make a smooth surface. To set the rivets I've used a hammer and punch. I've also used a press for a neater job.
I second what rchard saying bob
John, a second set of hands is invaluable. Have someone else hold the assembly on a stout buck, while you do the pounding. It is essential that the back of the rivet is supported to avoid damage to the drum.
Hope this helps.

I've always used a press. You have to be careful that you don't press the rivets too hard or you'll split out a really nice drum. Did that once...
