Well, technically anyone can rebuild an engine with the proper equipment and training. While this isn't quite so complicated I have yet to see a thread here that has a reasonable DIY ball pressurizer. That is, one that can be cheaply & easily assembled with common parts and minimal skill.
I find more threads where people have cobbled something together, sometimes with dangerous results (blowing the ends of their pressurized PVC tubes).
I would be all about a good DIY pressurizer. For now this $19 version looks more attractive than anything I have seen.
