I would do it now if we were not getting new vehicle next year. Then we are back to a cramped three-car garage. I am pouring concrete now to create a shed base, so that will help. But, two small kids, bikes, balls, etc.Space is always the issue. I would install my 2 post in the center back but I have a heavy 16 foot tall storage rack that I've filled up with good working yet expensive and useless crap like complete hydraulic power units and a new 3 phase electric motor to name a few that I know I won't really need and would live fine without. But I've spent too much time and money just to rid of them. Besides I have 6 lathes left and that's still too much. I only need 2 and at times the 3rd. The second mill has never been used once just tested. Bought these at auction because they were way too cheap to pass up then shoved them anywhere I could. So I need to stop hoarding machines and sell the rest. But I have a mental problem I think. I can't just leave empty space empty my mind just has to put something there. It drives me nuts, don't know if it's just me.
