Hi guys, thanks a lot for the advice about the taper. Personally i like the bow the way it is, but a lot of people said that it felt kinda hard to pull, especially at the beginning, although it only draws 42@28. So i was thinking what i could do about it without loosing to much of that speed that everybody loved that much.

@Jason: The curves are pretty sharp and what do you mean by 'parabolic width taper' ?

You do such nice work!

Parabolic width taper caries most of the width into the curve and more suddenly reduces to the tip. More of a rounded width profile reduction that is close to the end of the limb. A standerd width taper is more of a straighter line from say 2/3 or 3/4 limb to the tip, where you start the standard straight taper depends on design of course. How straight or how parabolic you need to be is a trial and error thing. It is best, if you're not sure on a new inrceased stack taper design experiment, to start out parabolic and reduce the width profile down until you get the tips opening up when and how much you want. The key moment to take note of is how many inches into the draw cycle does the string lift off the belly on both limbs. Hopefully it happens on both limbs at the same time and later in the draw cycle is preferable to get the most from curve.

Tell your friends that preload "early weight" is a desirable trait. Preload ussually means that the string nock will be tracking straighter and thrusting more efficiently at the best time for both accuracy and speed, the end of the shot cycle. Preload is more forgiving of a bad release because the string tends to get on track better at the moment the arrow is leaving the string. It is easier to quiten a bow with preload too.

Sweet bow Andy!! Ever any problem with the cloth under glass?

[Swissbow]

No didn't have any problems until now except the mess i had to clean up  because i used a lot of epoxy to make sure the cloth was completely soaked with it.  The next few bows i will do without it to see if there is any difference.

Thanks Jason, for the explanation about parabolic tiller.
