Hi Floyd,
As you might have guessed, I have been approached before to make a lift for pachiniko machines. I do have a machinist, but he needs plans. I don't really have the time to branch out into something that would require a bit of time to get right, let alone build from scratch. If I ever get some time to myself I may pursue this, but at this time, It's just me building RBS.

Thanks for thinking of me, and I will keep this in the back of my mind. If I had one to look at, or some sort of plans then I could proceed no problem. But I just don't have the time to reverse engineer from pictures... : )

Best regards,
-Matt
