I have just finished putting up Stu's New Dynamic Spine Calculator (rev 12-25-2010)
Here is a snapshot of what has been included in this latest release:
1. There has been many new shafts added to the database including: Easton 1820 Genesis, Beman ICS Bowhunters, Gold Tip Hunters, Carbon Express Predator II, Easton A/C/C, Easton Axis FMJ, and Bullseye Premium Shafts
2. Our Warbow shooting friends asked to increase the allowed draw weight so the new limit is now 240# --- That should cover everyone!
3. Center cut selections now include +3/4” and +7/8” for those shooting wide handled selfbows
4. The fletching options have been enhanced to now include "Bare Shaft" & "Other" options. When selecting other you now have a cell to enter you own specific weight if desired. Also, 2 and 4 fletch options have been include for 3”, 4”, and 5” feather sizes.
5. Corrected an error to the PSE X-Weave shaft deflection numbers.
6. Added “Data Library” tab to store your own arrow and bow data as you use the DSC. This separate page can be selected by clicking on the “tab” at the bottom and is available for you to fill out and store data for your own reference.
7. You can now select specific bow makers and types! The benefit here is that the riser cut is pre-programed and you now only need to enter the thickness of the strike plate you are using. The “generic” bow types at the top of the list are the same as before and should be used when your specific bow is not yet listed. When using a “generic” bow selection the strike plate position is entered as usual.
8. The graphical format has change so that only the values in the necessary fields are shown. As example, when selecting “Wood Shaft” from the arrow menu the three boxes directly below now become active and the values are visible. Vice-versa, if for example you select “2018” those same three fields are not needed and the values will not be visible.
9. The Instruction Sheet has been updated for the new features and also improved with clearer descriptions (hopefully!). As example, many were confused at how to correctly use the footing option so I have added a graphical diagram to help clarify the most common types and how they are intended to be inputted.
