Okay, so I've been working on this little project for quite a while. It's a vertical wobbler, from my own design. I think I've remade just about every part on the thing at least twice. As I tend to be my own worst critic, I am notorious for not being ever completely satified. So, without further ado, here is a pic or two on the progress:

Why the notch? Because I originally made the frame out of CRS, and broke off the tap in the end. Not wanting to remake the bushing (about the only part I got right the first try), I made the center to the thickness of the steel piece. Milling it was actually fairly succesful without too much drama. Still needs some sanding. The stainless is a scrap I scrounged from work. Nice and shiny with no work! Try not to notice the runs in the paint of the PVC base...
The piston rod:

Which is further along than the pic. I added flats on the larger end, cut to length and polished it. It was assembled to the piston, and fit better than I dared hope for.
More pictures to follow soon. If pics are too big, let me know and I'll resize them.
