Geez Bruce.....now I gotta' try and make one of these mate.
And I'm not sure if I'm up to the task 
This is absolutely bloody awesome !!!!!!
Lol...Jim, I didnt make it though, I bought a set of 5-6 pieces made by some person long ago, I could tell he didnt have much in the way of tooling but he sure had some neat idea's though. I did go through each item & try to Improve upon what I got.
Good luck with your build Jim & I look forward to seeing your rendition of this fun piece.
