Here are a couple pics of the new design... It's just rough sanded and has not been tillered yet... I feel I got really lucky being that it is the first one... I may do a little tweaking and stiffen up the tips just a hair...

If that is 28 in. it looks good. a couple more in. may need tip wedge.

Nice looking bend what's the stats on it !

I will have all the numbers in a few days... Right now she is 64" ntn, 54# and has over 91% string tension... The DFC also looks pretty good...

91% is way too low:)

Looks great!

Thanks for the good word guys...

Here are the numbers on that new bow...

64" ntn / 48.6# / string tension is 92%

480 gr. 28"/ 185 fps 29"/ 194fps

500gr. 28"/ 180 fps 29"/ 188fps

Good numbers and curve.

Very Nice Shredd. Good numbers there.
Can you explain the string tension number and how it was obtained?

Shredd · « **Reply #11 on:** October 17, 2018, 01:16:00 PM »

It is the percentage of tension on the string compared to the draw weight on the bow... I guess it does... The formula is: string tension divided by draw weight times two...

This bow DW 48.6 x 2= 97.2

ST 89.7 / 97.2 = 92%

BMorv · « **Reply #12 on:** October 17, 2018, 02:24:24 PM »

That makes sense to keep it relative to draw weight. One more question: how do you measure the tension in the string?

Shredd · « **Reply #13 on:** October 17, 2018, 04:51:19 PM »

Its just a simple scale in the middle of a bow string... Turnbuckle is for adjustment.. Here is a pic I sent on another forum of a grinder... The scale on the string just happens to be in it...

BMorv · « **Reply #14 on:** October 17, 2018, 06:13:47 PM »

Thanks for the pic. That's exactly what I had envisioned in my mind... I had no idea the string tension was that much. 89.7 lbs. Is that normal?

Shredd · « **Reply #15 on:** October 17, 2018, 07:55:05 PM »

String tension is close to double the draw weight...

It is the percentage of tension on the string compared to the draw weight on the bow... I made up a formula in which I did not know if it would go over 100%... I guess it does... The formula is: string tension divided by draw weight times two...

This bow DW 48.6 x 2= 97.2

ST 89.7 / 97.2 = 108%

Might have to modify my formula if it is going over 100%... It is basically just a reference number that helps me to read the bow better...

I’m not sure if your math in Florida is different than here in Ohio but.......
That’s 92.3% not 108

Now Roy...... I’m not trying to insult or make fun. Just wanna make sure all numbers are correct for comparison.

Roy from Pa · « **Reply #19 on:** October 17, 2018, 09:38:49 PM »

I got the same answer as you did so I guess Ohio and Pa are on the same page..

92.3%
