OK, always a lurker here, posted a few times with projects, have heisted a bunch of ideas (thanks to all), and always look on Google and search threads here to try to find answers before I have to ask but on this one I'm stuck. 
I want to build a core, or plug, aerator. Can get one new at Lowes for $317 and find a used one locally for around $200. I think I can build a better one for cheaper. Only thing I can not seem to find, and would be a P.I.T.A. for me to make would be the the actual core aerator thingies....the things that actually pull the plugs out of the ground.
Anyone have a source for these (kind of like I can get landscape rake tines or box blade teeth from Agri Supply)?
Much thanks if anyone can throw me a bone here.
