| I'm not too clear what you are saying here,scotstoxo.
Reading your last sentence first, it seems we agree that no bow has a perfectly fitting long rod. I think you are saying that this points to the makers doing it for a reason. I'm not sure that they would do that and never tell the archers what the reasons are.
I am not saying they do it wrong on purpose.
I am not saying they don't try to get it right.
Some will be pretty close to perfect, but not all.
I know that to get it dead right is not as easy as it sounds. Put any threaded rod into a tapped hole, and if the rod is long enough there will be an error show up.Threads do not fit that tightly together for a start. Put a log rod part way into the hole and it can shake about. When it is tightened down, the faces that meet, contribute to the error. If the faces are not square to the length of the rod or the hole,the rod gets pushed off centre.
I do not doubt the millions spent on research and development but I would expect a large proportion of that goes into designing new risers, new cams etc etc. Getting the long rod bushing perfectly in line, when they don't know whose long rod will be fitted into it, would seem wastful to me. Many bows are designed for the bowhunters not the target shooters. They use very short front rods which means the errors hardly show at all.
In a similar way, very few bows have limbs that are perfectly in line with the riser. This is not so obvious as the limb alignment is not so easy to check.
Interesting idea though.  |
