This was progress that I made yesterday afternoon.
I put the dado stack into my table saw and cut around one end of the legs to form a tenon that will go into the top. With the reduced thickness where the tenon was, I was able to cut them to length.
Then I started on making my own heavy duty levelling feet. Using hockey pucks and 1/2" bolts, etc. Levelling feet are a necessity on anything in my shop, since the floor isn't level - it's sloped toward a floor drain, which is near where the bench is, and the slope is more prominent in that area. The rubber pucks provide a good, solid foot that won't side around.
Mount a puck on the lathe. Drilling on the lathe ensures that I will have centered holes and is quicker and easier than finding the center, marking it, and then lining everything up on the drill press. But you could do it on the drill press as well - I've done it that way as well.
Drill 1/3 to 1/2 way into the puck with a forstner bit. Ideally I would have used 1 1/8" or 1 1/4" to do this, but the next size up from 1" that I could find in my shop was 1 1/2", so that's what I used. It'll work just fine.
Then drill the remainder of the way through with a 1/2" bit. I prefer to use brad point bits for drilling through the hockey pucks as it doesn't blow out the backside of the hole.
And four feet, ready for hardware.
Insert the 1/2" carriage bolt. Don't worry about the square portion not going in - when you tighten the nut down, it'll pull it in and it'll be nice and secure in place.
Then put a washer and a jam nut on the other side and tighten down. You can use a regular nut, but I used a jam nut for the fact that it was thinner. And, see, it pulled the carriage bolt in.
And four finished levelling feet! I will inset the coupling nuts into the bottom of the legs. You could use T-nuts as well, but the hardware store didn't have any 1/2" T-nuts.
And hockey pucks do make great feet for things in the shop. I've used them as feet on Delta stands as well.
