Just wanted to let all interested in this topic that you should not even think about starting to deal with the removal of spot welds until you have a spot weld drilling tool in your hands and ready to install in your drill motor. The one that you will find in the Eastwood Catalogue is an excellent tool. This tool together with an air chisel (I found one and four chisel bits for 20 bucks) and you are ready to rock and roll. The drilling tool, together with a 4500 strokes per minute chisel and you can make child’s play out of spot weld drilling. 😀
