RE: Bowtechs new cam system
We're all knowledgeable to some degree. Why can't we just get along? Let's debate and contribute, not argue.
I know that I'd be nowhere in this world if I hadn't depended on the expertise of others. If you go into an engineering meeting, you always have different disciplines from which to draw. An engineer can design it, but can it be produced - economically or otherwise.
As some of you may have seen in another post I made, I have the flu right now. I'm almost over it, but it really hit me hard. I had to close the shop yesterday and would have done it today, except that I have a customer from Greece who needed my help.
While I was waiting for him, I did some more testing on a variety of cam systems/manufacturers. I wasn't surprised at the complexity of this issue. I was doing both static and dynamic(full draw) analysis. What surprised me moreso was it's there in almost every design.
There was one bow, however, that was ABSOLUTELY perfect - not a bit of lean in either mode. Don't ask me because I won't tell you which manufacturer. The beauty of this bow on paper is only overshadowed by the fact that I can't get this bow to tune. I sent it back to the manufacturer a month ago because of the tuning problem. The manufacturer found that one limb pocket was cracked and that both were loose.
The bow came back totally fixed with new string/cable(s) and finitely adjusted to factory specs. It still won't tune and there is NO CAM LEAN in either mode. Go figure. I took a brand new model of the same bow off the shelf and it had cam lean of about 1/2". Go figure. And, for the most part, I've tuned this design over the years for numerous customers with absolutely no problems.
I know that there are some designs that will 'walk' in the opposite direction if you play with the split yokes incorrectly. Sometimes it's like trying to balance something on a razor blade. Just a touch too much and you're off in the opposite direction.
Another thing that I noticed today was that one of the BowTech bows which had been extremely tight on lean was not the same. The only thing I had done was change the cams to a different DL. As tight as the tolerances are, there are still tolerances to consider.
A bow is a very complex system. There are so many things that can cause variances in the end result. To think that you will get an ABSOLUTELY perfect product is wrong. Like a new car salesman told me a long time ago when I was nit-picking - "If you want a perfect product, you'll have to pay a LOT more."
So, let's give this new cam system a chance. I will continue to do testing; but, it can't/won't happen too soon. Remember, one cam designs have improved tremendously over the past ten years. I was quick to judge them, and rightfully so. But, isn't that what usually makes for a better product?
This flu has really kicked my butt. I wish you all good health.
