Thorbecke Brothers ball joint removal input HELP!

[m6z]

I'm needing some input/opinion/ideas on removeing the ball joints on a set of TB control arms. Need to take them apart for powder coat. I'm not sure how to go about pressing them out since the bottom of the cup is cut at a angle. I don't see how a typical BJ press would work because of the bevel cut. I also have a 20 ton upright press, should I just try and keep it level(prop it up on the short side) or ??????????
