How da hell do you pull off the hub from drum!

:happy10:Okay, so I did the back brakes. Golden!

Now for the fronts! I did some recon this afternoon and noticed the hubs and drums are pretty much fused together. Go figure!

I know a machine shop can seperate these hubs from drums but is there any kinda trick to pop dem suckers off! My back already hurts from the rear shoes as I spent a great deal of pounding away those 20yr old drums.
