Oddball projects for some Wood and Iron level badges

As we develop the Straw, Wood and Iron level of the PEP badges it's becoming likely that there will be innumerable projects where someone says something along the lines of "I welded up a merry-go-round.  Can I get points for that?  

Since it is a welding project, we'd hereby like it to be submitted as an Oddball project in the applicable badge thread.  This way we won't overload the regular Oddball badge with these sorts of awesome projects.

If your project is reasonable enough that we should consider making it a BB for the badge (roundwood teeter totter?), please post to the badge thread and explain your thinking.  

Pro tip:  It's preferred to have your creative project be a BB since the points are easier to get.  Points in a BB are based on how hard it is for a talented newbie to complete them.  Oddball points are based on how hard it is for an expert to complete them with a bit of luck.  So a given project will generally yield twice as many points if it's a BB instead of an oddball.

Is there a thread for Metalworking Oddball?  The Metalworking Badge Wood and Iron levels mention "Oddball points allowed", but it isn't a hyperlink to the oddball thread where those points can be achieved, and I haven't found the thread.

Good find R!  It's been fixed

Is there a list somewhere for which aspects have Oddball badges?

I just made a portable chicken perch out of a mix of bamboo and dimensional lumber and I couldn't find a BB it seemed to fit under...

Of course, since I was having to create the whole thing from scratch as I went along, it won't be worth much... An expert with a pattern could have knocked it out in an hour I expect, and it took me 6 hours. (I *really* need a decent workshop with stuff all accessible and handy!)

I think they are in Metalworking, Electricity, Plumbing and Homesteading.
