The hoist is from flea bay. It is a light duty engine hoist. Besides being light duty rated it also has a decent rate, 26 feet per minute without a sheave, so it goes up and down at a reasonable rate.
In my internet searches I found these used to be available through WalMart and a few other places. My showed up with the head of one of the bolts mounting the hoist to the metal frame was snapped off. Probably why many places say "discontinued". Easy to replace but it got me a $10 refund. $70 bucks shipped. I just left the weight hanging, it helps keep tension on the cable a little bit.
I may have to re-address the hoist mount. It is only held to the table with two bolts through the plywood. It does flex on the bolts, the plywood doesn't flex.
