The initial design started with a simple hexagon that would allow the inclusion of all the holes
Next I had to map out where the holes would go, keeping in mind that this was a universal plate design for both upper and lower deck.
After more testing and chcking I went ahead to put the pattern onto wood and cut the first test plate
Next the drilling holes need to be marked
and then drilled out.
and the main hole
Now a test fit
Now test assembly
Now a real assembly
Thats as far as I got on this day!!!
