There is a southafrican mountain bike company that changes the distance between the backwheel axel and the pedal axel depending on the size of the bike. They advertise this like its something special.
Makes you wonder what other non-changing parts are used to simplify production processes.
Take a hh style longbow. With it being flat. Cutting the tips back doesnt effect the reflex of the limbs.
So one former can fit all bow lengths.
But on reflex deflex... thats not the case. Cut a reflex deflex back and you get more deflex when unstrung. Ie less preload for any set BH.
So lets look at td recurve limbs.
Its possible to do the same with recurve limbs. Cutting the limb back. But that makes the recurve smaller.
Its also possible to have different formers for each limb length.
Just read a coment about another bowyer that tweeks the limb to work at a set draw length...
So ways to do this would be increase the fadeout. Or change the core tapers. Or change how much you make the limb work and where you make it work.
The next question is. When making a set of limbs how accurate are your weights. As most probably knows all bowyers miss limb weights. And with glass limbs you can rub the faces. Which changes the amount of glass to core.
0.010" glass each side and a thick core. Can make the same draw weight as 0.040" of glass and a much thinner core. But these would be different bows.
Its also possible to skinny a limb down to meet a weight. As in the 1.75" limb blank can be whittled down to a slender 1.5". And still be called the same bow model.
Since 2005. We have changed the widths of our limbs inkeeping with what we are finding works better.
So inline production changes also take place.
How would these kinds of bow changes effect bow tests.
The quote on another bowyer indicates that there might be a change to the dfc on a set bow length. So that means no on 62" brand X bow will be the same.
This excludes tiller changes during production
Without knowing the tricks of the trade on making different bow lengths. How do you know what the bow is going to be like?
