Back it.

use wood, Bamboo or sinew.

or Pike it (make limbs shorter)

or a mix of both.

So I take it you came in a little under weight with your new bow?  the easiest and fastest and most sure-fire fix there is would be to just start another.  :)  My first 2 or 3 came in underweight too.  Try to get it braced earlier, most people leave it on the long string too long and by the time they get to the full brace they are already under weight.   IF it is a succesful bow then just keep that one to practice your form with and try to make your next one heavier.   You know you are going to make another one anyways!    :)

I'm with Josh. Normally it's more than weight that I'd like to fix, so on the next one I adjust the handle, the tips, maybe the style or shape. Not only is the second one closer in draw to what I wanted, but there are usually other little aspects that I like. Unless I don't have anymore of that material, I usually just go make more :)

Heck if it's 70 inches go ahead and pike an inch off both limbs and make it 68 inches... should give you 4 or 5 lbs... I thought you meant it came in waaay under weight.   :)


....but still build another just because.   ...and post pics.  :)

What kind of wood? Might be able to go shorter?

i'm a big fan of heat treating a little reflex in if it's close to my target weight- for me it kinda depends on the wood, though

I gained 2.5#/inch when I piked.
I gained 10 pounds of draw weight when I went from 72"to 68"

Hey Kink, it looks great!  Good work on the bow, I think with your draw weight and draw length that this bow is not overly strained at all.  At the 70" length there was too high a degree of "overbuild" and you would have had a problem with some handshock and low arrow speed.  I bet it's a sweeter shooter now, too.

Now get back in the shop and start the next one!

That's the idea. Start another just like you did. Piking is a bowyer band aid which teaches you nothing about making weight. There are buidlalongs on my site. Your bow looks great! Jawge
