This postreally trigger my curisoty as I certainly feel Bowtech has still to 'perfect' the center pivot technology. Somehow my feelingsdrives a fear/scare in me most times when drawing a center pivot bow. Even though I've drawn them K's of time,there's always a possibility that something can go wrong.
And this is all due to the fact that I CONSTANTLY have to SNUG UP the allen bolts holding the bezel,limb and center pivot arm together.Also the spacers between the bezels and limb will compress over time, thus loosing its thickness and this will also cause those bolts to loosen.
I can say there is a big difference paper tuning these center pivot bows when those bolts are loose, as against when they're snugged up/tightened...(PS. NOT OVER-tightened)...as doing this can crack the bezel itself.
All in all, it is definitely necessary we 'constantly' check these bolts as quite a bit of energy is generated by these bows and this will manifest itself moreat the most vulnerable point on the bow...it is my view, that this point is at the center pivot.
As for addressing the movement...this happens at the axel ends of the center pivot arms and not where the center pivot arm bolts to the limbs itself. The point where the center pivot arm deflects from the riser as well as where it pivots on the limbs.
Nevbertheless I would definitely like to see BowTech 'improve' this design/engineeringon their newer CPbows.
