10 inch drums front bearing hub removal

I searched, and couldn't find anything. Can someone tell me how to remove the front bearing hubs form the brake drums. I have two 10 inch front hubs I would like to save, and don't want to scrap the hubs with the drums. It dosen't look like the studs can be pressed out easily, and i dont want to beat the hell out of them.
I was thinking of cutting the studs off evenly with the top of the drums, grinding them smooth, and then trying to press them out. The fac service manual dosen't mention front drum/hub separation any where.
