Ha, I’ve got you all beat!!
In my shop next to my house (if that counts).
I have an old Brown and Sharpe NC Machining center that I have retrofitted to CNC and new electronics.
It was 32,500 lbs when I bought it, but is now slimmed down to about 28,000 lbs.
This is not for a business, it is just a hobby.
Next would be my wife’s corner entertainment center at about 500lbs.
Or the forklift at 7,000, but the forklift seems lighter as it moves itself.
MacGyver.
While my spa is damn heavy (~400 gallons + spa) I am pretty sure my toolbox outweighs it. 6’ wide 2’ deep and 5’ high full of tools. I am guessing it at about 4,000 lbs.
It’s so heavy the last couple of times I have gone to move it, I have rented a truck with a trailer that lowered to the ground.
Me too on the rolltop desk. I call mine ‘The Monstrosity’ since it’s built to swallow a 21" CRT in a gulp and not burp. Cherry, disassembles into three or four pieces too with bunches of drawers. Got it off someone’s houseboat, but it can’t be that heavy since it only took three people to move. It took five or six people to assemble, since we got it back to my apartment just when my sister’s friends were over to pick her up. They insisted on helping us. 
No cat, but I’ll keep an eye out for that there other thing crashing through my bedroom window.
Bridgeport,1,950#.Without the Kurt vise.
OP,I liked that menorah you made a while back.You must be happy with the drill press.
The heaviest thing I own is a pool table, and the slates themselves weigh 750 pounds, so I’m sure the entire table is well over 1000 lbs. And I don’t even have a house, just an apartment. I’m not looking forward to moving it again once I move out. In fact, I think I just might stay.
We have a Ford farm tractor, out in the barn. Have no idea what it weighs, but it moves itself.
We have a 1860’s pump organ that is a PITA to move. The woodwork on it is amazing, but it takes up alot of real estate.
A claw footed bathtub is a micro garden in my back yard. After my husband dumped it off the back end of the pickup and URRRRGHHHHHH’d it to a spot by the deck, he said, “There is where it will be for the rest of its life.”
One day in the future, we will both be the recipients of two pool tables. I’ve always wanted to do the Drew Carey shooting pool outside thing, and when these come into our lives, I just might build a garden around them ( and tarp them for the crapactular weather.)
Thanks! Yeah, it’s nice but now I realize that I need a milling machine as well! I can tell my wife: “See honey, Carson has one…”
Wow. At 225, I weigh more than any of my belongings.
