Chuck,
Lot's of modeling clay, and release agent!!!! I don't know how many times I looked at my setup trying to visualize all the spots that need to be plugged up. Just take it slow. I think bedding the tip of the hanger, as well as a small pad on each side at the rear, will go a long way towards keeping the forearm from rocking. My main motivation is to make it as solid as possible, so that I can have the tightest forearm to barrel fit, yet still maintain a free float.
