Ok I am about to make some bones and and I would love to know why was it decided that 19mm seamless was the way to go for top wishbones? Why not 18mm or 20mm?
From what I am led to believe, in industry, 18mm and 20mm are by far the more frequently used tubes and hence far more easily obtained by the likes of me who is building in true locost style and trying to spend nothing whatsoever
I am just a little curious to know where the 19mm came from particularaly as i have about 5m of 18mm hydraulic seamless with a 2.65 wall (I think) which was very kindly donated
to the cause lying in my workshop.
So what do you guys think; should I throw caution to the wind and use the 18mm tube?
