I did build the box on my 33% Edga square and had Roger make me the standoffs.He talked me out machining the taper because he said it be fairly expensive.He did however caculate the offset for me on his computer and make two of the standoffs longer than the others,but they are cut square.There was no extra charge for that.So far after about twenty flights all is well.I just thought I would do this right,not that there's anything wrong my Edge.
