Stroke with only Pistons and Crank?

Yes it's something I try to put $100 a week away and then by the end of 3 months or so I can purchase something large but it takes time and work...
Oh yeah and patience...
I'm sure. I'm very fortunate to be able to do all that I do. I just don't have that kind of budget. I probably never will. I enjoy playing with junk. It's actually pretty rewarding.
