Just thought id post this (I hope the image shows up) to see what people think. I've seen a lot of other neat ideas for diy cappers, this one is complete overkill but it was fun to build. It weighs about 15 pounds and is made mostly of 6061 aluminum with a steel base and 4130 CroMo tube for the height adjustment. the thing slides on a steel dovetail and has interchangeable capping bells.
