Delivery day came and went! There was a great old storm coming through but the tank was unloaded and not a chip or crack in it.
I hired one company that brought it into the house but then looked at the stairwell and said no way. So I built a 2x2 frame of the exact tank dimensions (minus the overflow) and made a dry run through the stairwell and it fit, just like my measurements suggested it would, sans overflow.
After trying to cut the overflow off for over five hours (razor blade, 20g wire, etc.) and with the movers coming in a couple hours I made the hard decision and broke the smallest pane on the overflow and peeled the rest off. It came off easy once I had the once pane off. Made me cry inside a little but oh well, better the tank is downstairs and I have to repair one little pane of glass.
So the movers showed up and looked at the route and weren't too stoked. But they didn't complain, just got their equipment together and got to work, The laid the tank, starfire up, on the piano dolly, then lashed a wheeled dolly onto the overflow side. After some swearing and back breaking work, they had it down safe and sound! I paid them, am tipped them well to boot!
Here it is in place!
