Make a short cart/table to hold the enlarger so that the column fits in the room with your ceiling height. On each side of the short enlarger table, place a cabinet on the sides of which are horizontally level 2x2 inch stringers placed at convenient intervals. Get a piece of laminated countrtop (i.e. heavy, flat, and stable) that you can place on the stringers at the apporpriate height for the size of enlargement you are making. Try to do some forethought so that the print size tht you make the most results in a comfortable easel position. For Larger prints, drop the piece of counter top to a lower level or remove completely and use the enlarger baseboard. In my setup, I use just one position for the countertop or else I remove it and use the enlarger baseboard.
As an alternative, wall mount the enlarger column and use the 2 cabinets interconnected with a moveable piece of countertop as noted above.
Be sure that the enlarger negative carriage and the final position of the easel are in alignment.
