We make welded steel frames in house. This is one of the steps where we first cut the raw steel into 4 sides. We then use a drill press as you see in this video to make holes for the screws to hold the inside frame. To make the screw heads level with the steel we drill one more time with a countersink bit in the drill press to make the holes a bit recessed as you see in the final results. We have the drill speed set at very low, so the drill bit does not heat up causing it to break. This process takes about 30-40 minutes per frame depending on the size of the frame. I will post most more videos about the other steps involved in making these welded steel custom frames.
