my latest board bow came in just a hair too light.

this one is hickory.

question for those who would know......

if i shorten the bow by 1 inch, by filing the nock grooves a half inch closer to center on each end, will i gain any poundage at all?

only looking for maybe a 2 pound increase.

i have room on the tip overlay to do it with not much hassle.

heres a pic, i would re file at roughly the green line.

How long is it and what is the draw weight?

duh,that would help alot wouldnt it haha

currently its 64 5/8" nock to nock. and pulling 33# at 27" draw.

Start by taking 3/4" off each end. That will be close.

Rob Nicol build some beautiful double nock bows over in Australia. He had pictures of one posted just a week or two ago along with the draw weight for each position. You might want to look up some of his work. He works under the name Flatline Custom Bows. I just went and took a look at his Facebook page. You can probably get a good idea how much an inch will change the weight based on some of his posts.

I think fdp should get you in the ballpark.

PS pretty backing. Almost look like Dbar’s turkey feathers backing.

its nowhere near as cool as the feather backing.

its just a wide ribbon that has photo realistic tree bark on it.

looks pretty cool though :)

Double Noch should solve the issue.

1 inch from both ends will bet you about 5 pounds. It will also get you increased set so it is hard to tell the eventual outcome.

I've done it but not a fan of the process.

george, can you elaborate why you arent a fan?

so,in theory,

a half inch from both ends should get me about 2.5# ?

i know thats just a guess, and i doubt the weight increase is linear.

it already has some set, an inch or so, which im not really worried about.

its a great shooter so far though, i may just leave it as is for a while.

I’m going to guess you have about a 10” handle. That gives you 54” of working limb if everything is working to its potential.

54 / 2 = 27” draw. If you shorten two inches you give up that much working limb. Now you are doing the work of a 27” draw with working limb length of a 26” draw. It’s not saying it can’t be done. I’m sure it can. But I think what George is trying to tell you. It will put more stress on the limbs. Hickory is a bit poor in compression from what I am told. It’s probably not going to like the extra stress. It probably will take more set and wear out faster.

If you started out overbuilt with 58” of working limb and removed two inches . You would get to 56” of working limb and have limbs that would work for a 28”draw. That would still put more stress on limbs than the 58” but you would still be slightly overbuilt and hopefully able to handle the stress.

The shorter the limbs the less wood in both length and thickness we have to spread those stresses over for the same draw length. Yes our weight will increase. But the wood available to handle the stress will decrease

That depends. I have increased poundage on self bows by shortening the limbs as much as 1.5 inches. Then I give the bow a deep belly heat treat to minimize any more limb set, and it can increase poundage. I am not a fan of it either, but use it as a last ditch effort if I am lower in poundage than I want to be on a self bow. Not telling you to do that. Only what I have done. I have also reflexed limb tips an inch,or so ,and with a belly heat treat, and increased bow poundage. You can also increase poundage with just a deep belly heat treat, but with a backed bow it would not be a good idea unless you have more backing material to re do the bow if you screw it up which I have done before.

brian, handle is 12" to the end of the fades at the dark strip of wenge running through the middle.

seems the consensus is i should leave well enough alone lol

i really like how it turned out, just have to knock the shine off with steel wool, (used a gloss finish this time with the intention of taking it to a satin finish)

id hate to mess it up somehow, because it shoots really good for me.

thanks everyone for the advice :)

I think that’s the right choice . You can always try something different on the next one. Bjrogg

I think you have too much wood at the tips. I would simply put another string grooves 1/2 inch below the old ones and see how it goes.

see now that's what i thought too.

i feel i made the tip overlays too long.

I think you could back up your fades a bit and get more wood working close to the riser and then chop the tips back a bit.

I am not a fan because you have made the bow shorter causing more set to happen. Also, you won't learn to make weight. Yes, a 1/2 inch from both ends will give you 2.5 pounds. But you can try it and see if you become a fan. :) Jawge

you can tie a nock on lower and see where it gets you,, or you could pull the bow a bit further and get your poundage,

It doesn't necessarily cause set . As long as the bow is slightly overbuilt in width it will stand shortening.

I built a wide six foot bow and cut it down 10 inches with no increase in set.
