How to increase recoil weight?

[ricardo]

For a given amount of lead, i.e 5 grams, where do I put it to maximize increase in recoil weight?

1. 12
2. 3/9
3. 6
4. Butt cap

Does putting lead in the butt cap increase recoil weight at all?

If I increase swingweight, do I automatically increase recoil weight?

Thank you all in advance..

As i understand it lead at 12pm has the biggest increase because it increases swing weight by 3 times and only increases static weight by one times

So i think an increase in sw will by math increase recoil weight

RW = SW - mdd

m = mass in kg (since SW is measured in kg*cm^2)
d = distance in cm from balance point to axis you measure swingweight from (usually somewhere close to 10 cm).

Recoil Weight is the inertia around the center of mass. The farther you put the lead from the center of mass the greater the increase in RW. Therefore for an even balanced racket either placing mass at 12 or the butt increases RW the same. 3, 6, & 9 will not have as large and increase as butt and 12.

Putting mass in the butt increases RW a great deal using the formula ( mass times distance squared) you can easily calculate the increase. For example a racket with a 32 cm balance let's see what happens if you add a 9 g overgrip. The center of the OG is about at 10 cm so the 9 g is added at about 22 cm from the balance point. 22x22x.009 = 4.356 increase. If you add 9 g at 0 cm 32x32x.009 = 9.216. It's easy to see now too the farther from the COM the greater the increase.

You can increase SW a little by add mass at the balance point. The SW axis is 10 cm so adding 9 g at the balance point increases SW by 22x22x.009 = 4.356. But using the formula again 0x0x.009 = 0. So no just because you increase RW or SW does not mean you increase the other.

EDIT: @ricardo What are you trying to do. It would be easier to answer specific questions.

Thank you very much, my Master.
I want to make my racket(Wilson Steam 105s) more comfortable.

I will add most of the weight (>80%) in the butt.
My swingweight is already high (329).
However, my twistweight is (<15).
I will add a little weight @11/1 or 10/2.

I will report back.

What do you think about achieving a high recoil weight (>175) with a light racquet (270 g)? Is it possible? What about its effects?

Put some black or dark blue string in your racket. Drill for an hour or 2. Then, look on your strings to see where the most ball fuzz is. Add weight adjacent to that area (where the fuzz is).
