How much weight does piking really add?

[bowman_79]

I came in too light on my last bow. Its 45#@28 and 69 1/2 ntn. How much weight would it add if I took off an inch on each end?

There's a formula, I think it was in an article in one of the first bowyers jurnal, if not In one of the primitive archers published in the last year

Thanks, I found it.

Please provide a link. I cannot find it.

Don't know about the formula but I get between 5 and 10 lbs for an inch off both ends.

Is that for glass and wood bows??

I have shortened a few glass and wood longbows including a Mosshorn, a Kaibab Chaparall, and a Kabekona River.   (I wanted to make sure I could shoot short bows before spending the money to buy a Super Shrew.)  I shortened them from starting lengths of 60-62" and took off 3-5 inches per bow.  I picked up around 4-5 pounds per inch. An inch off of each end would give you an extra 8-9 pounds.  If you take off more than a couple of inches your pounds go up more than that and I had to narrow the limbs some to bring the weight down to where I wanted when I shortened the bow 5 inches.
