It's a pretty stupid short roof. I won't bitch too much because it is a dedicated room to me.
to maintain 6" clearance as access above hopper it will leave the handle of the press at 42.5ish inches. I am assuming a bench height of 34.5 inches and press mounted directly to bench.
My issue with with this is this is about 7 inches lower than my current rig up. ( I reload standing).
if I can trim the case feeder as others have suggested I can better maintain the proper height for the press handle. This sounds like the best option for path forward.
if I trim the unit then I will use a strong mount instead building the bench to the proper height, unless that's a bad idea.
