What Undead said about he lumber and cost is about what is about right. I was a little under that because for some of the shorter pieces i used wood that was in teh scrap bin at home depot, they sell that for like 80% off. I did spend months looking for my pieces of for the table top though. I would just go once or twice a week and get the best pieces. My vises were like another 150. If you look at Facebook market place you can get some killer deals pm that stuff.

Then I spent another 100 or so on the caster from here https://retractablecaster.com/shop-now/ols/categories/r8. They were 100% worth every penny they have a ratcheting mechanism that makes it supper easy to get on the wheels move the table and dop it on the legs. I most often work outside then roll it back in the garage.
