Finally - 48" hickory recurve selfbow
« on: February 14, 2010, 04:45:44 pm »
So I posted pics of this bow while it was unfinished and here it is finally. Hickory selfbow, 48" ntn about 50#@28". Drawn to about 31" in the pics. It is stained with ebony stain. This bow was extremely fun to make. It took a lot of string follow so it has very little tension at brace height so its actually slow. But it looks pretty sweet and thats good enough for me. Thanks for looking.

Really nice work.. Did you steam or dry-heat bend the tips?

El Destructo - Thanks. The whole point of this bow for me was to see if I could get a selfbow to look and draw like a korean/turkish bow. I'm just glad it turned out.

KenH - I boiled the tips. Thanks for looking.

Are you sure you are pulling it back far enough?  :o  :o  :o
Cool bow (and not just cos you've stuck it in the snow ::) )

Wow Ryoon, that is amazing how far that is bending. The tiller looks very good and to be together at the draw length to bow length ratio is incredible. Did it have some deflex to start with?.

 :o :o :o  That is a really neat little bow...It's a little bit of a shame about all that string follow but I guess you need a trade off with all that bending it's doing.  Great Bow man I'm really impressed.

If you want the bow to take less set you should temper the belly.  The temper allow the bow to pull further, reduce set, and will increase draw weight a bit.  Hickory takes well to tempering.  If you're up for more work on the bow (or for the next one) it'd be an easy fix to heat the whole working area and put it in a form (I'll explain that in a min).  Once in the form and cooled down, you temper the wood until it starts to change color.  The form is basically a 2by3 or 2by4 cut to the length between the big bends before the statics, with a block of wood in the middle.  You clamp the handle to the block of wood (cut off of 2by4) and the weight of the tips should bring the ends down to the ends of the board with heat.  If it's not enough you can add pressure with weights or even clamp the ends down. This should give you 1.5in of reflex before the static tips right at the big bends.  It will take some set again but the tempering will help with that.  So it should end up .5in +or- of straight.  An important thing to remember is to not temper the back.  Unlike the belly it will make the back brittle.  Also remember to temper the whole belly of the bow not just the working area.  It will add strength to the whole bow not only the bending parts if you do it that way.  Tempering will make the bow perform better and in my opinion makes it look cooler too.

Amazing that you got a self bow that short to have such a long draw.  Very impressive.

Thanks guys. There was no deflex in this stave when I started. Pipe straight.

jessepeltan - I actually did heat treat this bow. TWICE! Still took this much set.

sulphur - I didn't want to sinew it even if I had some. I just wanted to see if I could make it a selfbow.

Wow it still took that much set after heat treating!  Was the wood too wet?  Hickory is sensitive to moisture.  I understand that that's a lot of stress on the bow, but that's a lot of set for a heat treated bow.  The tiller is spot on so it wasn't that.
