I was out doing some trial run work on the lathe today and realized that I am going to have to make some changes before long like as soon as I can! My thought is to get some square plate that will fit inside some 2 x 2 square tubing, remove one leg at a time drill a hole to mount the square plate and that being like 2 inch square the slide the metal tube up over the square plate drill the holes for large screws so that the tubing is secured the plates then do as you mentioned weld plated to the bottom of the tubing with adjustable feet. the table top as it is over 11/2 thick as it is now but the legs do need more stability and not sure if gussets alone will do the job. But I need to get back in stroke and play some, I had nose surgery in December so I couldn't play as I couldn't bend my head down for long. But I did get to try my hand at some Delrin for collets today and it worked ok just need some do some fine tuning.
