Stu Miller's Spine Calculator
« on: January 07, 2011, 04:22:00 AM »
I have used the calculator to determine arrow selection for a number of bows.  I noticed the data library tab at the bottom and thought that would be a great place to store everything as opposed to saving multiple versions of the calculator with the data entered.  I was just wondering if there was an easy way to transport data from the calculator to the data library area without completely re-typing it there.  I also want to thank Stu Miller for this great tool - it has saved me a lot of time, money, and frustration!

Been thinking the same thing for the past two weeks.  Instead of using the database I just do a Save As on each different bow/arrow set up.  Set up a folder just for Stu's calculator spreadsheets.  Currently working on evaluating 4 different spine/point weights on Surewood's and one for Beman MFX carbons.  It would be nice like ya said to just click the data onto one sheet.

I play with the calculator all the time and didn't realize that tab was there. This thing just keeps getting better the more I use it.

Hello Guys,
I think I have worked up a decent solution to the issue of getting your data easily into the library page.  I added a "header" line to the data library page that is automatically filled out with as much detail as possble of your setup that has been intered in the main calculator page.  You can now simply copy and paste that data into any of the archived rows below the header....this info then stays put and becomes your historical data.  The added bonus is that I have made it so the AMO deflection and spine as well as the shaft diameter now shows in the header line for any shaft selected.  This was a previous request from someone who mentioned that fining this information on all the various shafts is sometimes difficult.  Now you can see all the data at will!

Les is testing it out now and if he gives it a thumbs up then it will be released on the website very soon.
-Stu

TEST TEST TEST

segment of email I got from Stu.
Hello Les,
  Take a look at the new data library page.  The idea is that whatever is inputted on the main page is duplicated in the top line of the library page.  From there the user can sect those cells and copy them to any archive line below.  The other cool thing is that whatever shaft is selected on the main page, now you can click over to the library to see the AMO deflection and static spine as well as shaft diameter.

  WOW, I have sent some feed back to Stu and I think we can all look forward to an early 2011 release.  Simply amazing what Stu does for this community.

I really love youre programm, though my bareshaft results are that much off that even with a 15 for personal form i cant make them work in the programm.
Nevertheless i cherish it much for a starting point.

Now I have to figure out how to save to the data library the different bows.

I love the fact that he has different makes of bows already in the calculator.

Stu will continue to add bows to the list as he get qualified data.  
I just sent him the information on Big Jims Buffalo and Thunderchild after speaking with Jim.
Both bows are cut to center.

Stu's calculator has been so good at tuning arrows for me, I no longer bare shaft tune. It's like a "what if" program. You can put different sized shafts in and it will give you a tunable arrow in about 15 minutes of time without having to buy arrows. Just a little tweaking with point weight and brace height and I end up with arrows that fly great. Just make sure you put in the correct info needed or it won't work right.

Thanks, Night Wing! One more question - when you are using wood shafts, what do you put in the insert weight cell (4)?

Huntress,

You must have me mixed up with someone else. I've never used wood for arrows. I'm strictly an aluminum arrow guy. With me shooting low poundages and my 30" draw length, I wanted to shoot 32" BOP arrows. Aluminum was easier to work with than wood or carbon. I never took to wood. With carbon, the correct spine for me with carbon arrows, the carbon shafts only come full length in 30"-31" lengths so I can't make a 32" arrow. Aluminum gave me what I needed.

Using Stu's program shooting my 42# bow, I could shoot 2114s, 2212s, 2213s, 2215s and 2117's. I was lucky since I have 32" test arrows from 2013 all the way up to 2314. All I had to do was use the suggested field point weights, tweak the point weight with 5 grain brass washers behind the field points and adjust the brace height up or down a little.

I found out my bow really likes 2215s and 2117s since they really wallop and deeply penetrate into a bag target with very little trajectory drop between 10-20 yards which is my limit. Without using Stu's program, I would never have even thought about shooting a 2215 or 2117 arrow out of my 42# bow and I finally chose the 2117.

One thing I do to confirm what Stu's program suggests, I paper tune at 5 yards. If I can shoot a bullet hole without any tears, I'm there. One added bonus, Stu's program doesn't give me any aggravation that bare shaft tuning always gave me.
Blacktail TD Recurve: 66", 42# @ 30". Arrow: 32", 2212. PW: 75 Grains. AW: 421 Grains. GPP: 10.02
Blacktail TD Recurve: 66", 37# @ 30". Arrow: 32", 2212. PW: 75 Grains. AW: 421 Grains. GPP: 11.37

Huntress you need to select wood shafts and input the data below the box.  Here is an example of the calculator with wood shafts.

Sorry, Night Wing. I didn't realize. I don't know the first thing about carbon or aluminum. I've shot wood all my life.

Thanks for the example, metsastaja. I see what I was doing wrong now!
