I want to proudly say I work on one project at a time. But I have to admit I have at least three bikes in some state of disassembly at the moment. But all of them are heaping piles of doodie.
I did have a survivor though I bought recently that came to the front of the queue so I will crank things like that out fairly quickly. But because I'm not flipping and only wrenching for the enjoyment of it, I don't have to get in a hurry. In fact I can flat drag a project out, I'll buy parts for one step of the build and when that step is complete, I'll order the parts for the next step.
In a way, dragging it out save me money. Because if I didn't have something to work on, I'd buy another bike.
