I was playing around Sunday with a bench mount drill press and started to build a stand to bolt it to so I could move it around were ever I needed it. I went up to Big Lots and bought a heavy umbrella base stand for about 20 bucks, found some pipe and some 1/4" steal plate in the garage and proceeded to cut and weld it up. Had it all painted nice and pretty, bolted the drill press to it and when I went to put it back in the garage by rolling it on the stand (kind of how a garbage man rolls a trash can) the top weld between the pipe and 1/4 steal plate broke, not all the way but I heard it crack and knew the weld gave way. I got to thinking about the pipe and it being galvanized. Did I just learn a life lesson here because the weld will not penetrate the galvanized pipe or did I just not get the weld to penetrate?
