hubs and hubs

I messed up my front hub a few weeks ago by running loose lugnuts...it reamed out the holes and the lug nuts wouldn't tighten....a friend brought me the front end from an old jeep he had....turns out to be 11" brakes on it vs 10' on mine.... after grinding the lug studs and a lot of hammering I finely got the 10" brake drum seperated from the bad hub....I found a better way to seperate the drum from the hub on the 11"...I started driving a chisel between the hub and drum...went just a little at a time and it took several rounds, but it was a lot faster and easier than grinding the lug studs off and hammering them out...the knurls all look good, so I don't think it hurt it any...gonna get new lug studs today and we will see
