Very nice work.  It amazes me that you can get a stiff handled, static tipped bow of a 54" length to bend to a 26" draw.  You are not supposed to be able to do that you know.

Tom,
Building a bow with those specifications would be extremely difficult for a selfbow, but when laminations (Osage and boo) are used you should be able to shorten the bows length without risking durability/safety of the bow.  Most people building bows use the rule of thumb of doubling the draw length and adding the length of the riser for the minimum length.  That formula has a lot of safety built into the bow and works well for almost any wood.  Boo and Osage are really tough wood and allow these guidelines to be altered downward.  The rule of thumb I have used for the last several years is to double the draw length and be extremely careful with the tillering.  For example, most of my Osage selfbows are between 58-60 inches and I draw them between 28-29 inches with weights ranging between 55-65 pounds.  I haven’t had one fail with these shorter specifications, but they do have a tendency to follow the string a little more then the longer bows I have made (about ½” more).  Also, I leave all my tips non-bending and slightly reflexed for the first 4-6 inches

Just goes to show you how much leeway is built into our rules of thumb.  And yes I agree that a BBO can do things a selfbow can't.

Thanks for showing us what boo and hedge can do Uwe.

Uwe, I kind of like full draw pictures with a wall behind them.  It allows us to see the great tiller you have on this bow.  I think it will do great in the BOM contest.  Justin

   Very nice bow. Bamboo an Osage makes a great combination.

This is a great picture of a fine bow at full draw, folks! And bookmarked for January Laminant Bow of the Month, too. Looking forward to seeing it again next week.

I'll bet it's really something. I always saw everyone putting up photos of their osage bows, or Osage backed  boo bows, or this and that. Up until Now I've only used, oak, and ask. I finally got a chance to use the black locust that had forgotten about, around two years ago. I had hidden it behind a wardrobe to prevent family members from destroying it somehow, Well anyways I found it, and made a Wee 40" flatbow. Man Alive Its unlike everything I have ever used. They saw yew and Osage are even better.
 Then With the addition of bamboo as a back WOOOO! I'd like to shoot something like that, man.

It makes me feel happy! Especially that this bow may come into the BOM- contest!
@Gordon: The draw is as I just measured it up about 25". It is amazing that my draw has changed over the years to a shorter draw. But this seems to be a phenomane (hope its correct writing) which appears to other bowyers too, as I have been reading.
Some additional words to this bow. The handle is salmon leather and the ermine taildecoration is coming its way with red woolcloth and phaesantfeathers as well as tin cones. The horntips are made of african watussi horn. The osagebelly is spliced in the handle and has a laminated osageriser. The string is dacron.
Additional you see some arrows made of cane with aluminiumpoints crafted on my lathe and osagenocks with a dowelinsert for the caneshaft (nock 1 piece of osage).

Very nice full draw pic looks great. What did you use to glue on that riser? It looks like the top limb starts bending right at the riser. You must have good glue for it to be staying on so nicely.               Jesse
