Nice lift! Favorited. :-)

Thanks :D.

No problem! :-)

Just saw The Exception on Youtube. Mind-blowingly awesome, one of the best ball machines I have seen! I love all the brand new elements (and there were lots). Then I saw the reference to instructables in the element videos and became even more excited! ;-)

Thanks. Do you think you are going to use some of the elements? :-)

Maybe...I'll have to see where they might fit in. ;-)

Can you please put videos of these in your 'ibles as well? All these awesome things you are making look truly... awesome, however, a video would be very helpful to find out what exactly it does without having to build it first.

Of course :-).
