Upsetting the drifters

Blacksmithing today. First with a little rack to hold extra hammers and some bending fixtures, then a hook rack for the items I use everyday next to the stove. Drawing down is pretty much under the belt, but upsetting and drifting are still areas where I lack tools. I wanted to upset the bases of the hooks I made and used an air hammer to blast them while held in the vice like they were rivets having their heads flattened. I have one poker made of a length of concrete rebar, and I wanted to drift a hole in that so that it could be hooked up with the other tools, I got there with an old cold chisel, but it made me realize I need to get a few more jigs and fixtures made if I want to make any serious holes in steel.
