I have a 3 pc longbow that is 62" long. Semi narrow limbs and strings up into a 'D' shape; but it's a r/d design.

How much weight gain would be increased if the tips were shorten an inch each?

I know the bow pulls smoothly past 29" right not. My draw length is 28" and it's a little light. Just wondering if I want to have the bow reworked to add weight.

According to Bingham, it's about 7 lbs per inch. In my experience, it's more like 3-4 lbs per inch.

When you shorten the limbs you will also loose reflex in the tips which will detract from performance. You may end up with more draw weight for less performance.

That is an interesting and alarming point you made badger; thanks.

Depends on amount of taper in limbs, Plus a few other small things.

I personally would just enjoy the bow as is. Its nice to have bows with different draw weights IMHO.

How much weight you gain depends on the initial bow weight? Shortening the bow to 60 inches will also increase your finger pinch slightly. And, of course, Badger is correct. I also agree with Deer51. Nice to have bows of several weights. Use the lighter one to work on form. If you're a one bow person, might be better to sell or trade for exactly what you want.

IT being a 3 pc you could just look at having another set of limbs made.

You could see exactly how much weight it would gain by tying on nocks...not the safest or best option to shoot with them but I have done it on bows up to 50lbs myself when determining draw weight before cutting nocks.

The bowyer no longer is making bows. It was good asking the question though. Thanks everyone.

even if he doens't make them someone else could make limbs for it. Before Mike at maddog did such things.

Get new limbs. The length was figured in with the R/D.like said above keep the way it is for good form practice. I would not shorten that particular bow. Bmb

I made tapered shim plates out of maple and just shimmed the limb tips forward an inch. Got 5# more out of the bow.

Sell it and get what you really want.

You start mucking around with it and you'll probably wind up with fire wood.

I have always gotten somewhere around 5#'s per inch of length removed ....... however as mentioned several times above removing length is not always the best way to go.The length was factored in in the building of the bow and for what ever reason they just don't seem to shoot as good for me afterwards.Again maybe pass that one along and buy what you really want in length and draw weight bd

THRC has the best solution a wedge shaped shim that will move the tip to more reflex. If you don't like it you only have to take the shim back off.
