I know where you are coming from here. I was offered at one point to "rent" time on a machine from my boss for my own personal work; but never took the offer as I wanted nothing to do with my bosses equipment after hours. I am now a contract worker for a past boss and my current boss. But all work is done on my equipment in my own shop. It is much harder to work around but the end result is far more rewarding. If you do end up with some or all of your bosses business at that point bring your machine in to the family.
my 2 cents in the jar.
good luck, any endeavor like this is always hard.
