my k95 is very headlight and I want to balance it out. How many grams would I put @ 3 and 9 to balance it out?

That depends on how headlight it is.

You'll need quite a lot.
A K six one 95 weighs in at about 349 grams.
8 pts headlight would put the balance at 22,5inch from the butt.

Suppose you put lead at 20 inch from the butt (that should be around 3 and 9)

You'll then need a whopping 40 to 50 grams of lead to get to even balance.
When put at 25 inch (around 10 and 2), you'll 'only' need 15 to 20 grams to get even balance.

This is a pretty handy webpage:

There was an excel sheet as well, somewhere on this forum.

Why do you want to get an even balance in the first place?

you could just add lead tape and see as it becomes more evenly balanced. you're probably going to have to layer the lead on top of each other anyway.

No. 8pt HL would be 27in/2 - 8*1/8in = 12.5" from butt.

i do not think you need that much lead, maybe 6 grams max... swingweight and weight is allready pretty high, 340sw.

To get it to the even balance from 8HL, you need MUCH more than 6g in the hoop, even at 12 o'clock.
6g would move it maybe 2 points to the head.

you need to move the balance 1 inch twd the Head to even it (from 8 HL).

I am estimating about 20g or so, but you would need to experiment...

The SW would be insane in that case

i know, but the 6 grams is just my advice... i am not so sure the OP wants to make it completely even as that will swing amazingly heavy then, unplayable IMO.. it is a warning.

I thought that is what he meant by "balancing it out"? Otherwise, his question makes no sense to me...

I was switching back and forth between cm and inch, and making lots of mistakes. FWIW, I did use 12,5 inch for the calculation.

ehh im probably just going to go for 4 points headlight

So would it be correct to assume that 3g equals moving the balance 1pt?

What is the estimated additional swingweight that is added moving the balance 1pt making a racquet more head heavy?

What would it be if you moved the balance toward being more head light?

This is a good site for measuring swingweight.
Its quite interesting...i added 7g to the hoop and my swingweight went up from 330 to 360.

How does 8pts headlight feel? Why do you want to change it?

Play with the calculator and you can see...

I am not sure 3g = 1PT...I was estimating it, also assuming 12 o'clock weight position

The TW Reverse Engineering calculator is the most useful thing around for customization:

You'd need about 12.5 grams at 12 o'clock to move the balance by 1/2" (4 points). These 12.5 grams at 12 o'clock will change your swingweight from 340 to 390! I think you're better off with a different frame, unless you're ready for SW2:).
