Nice bow Uwe. Looking forward to full draw pics. 
   Your pics are 800x600. Can you make them 640x480 instead. I can't see the whole pic on my screen. I know you just figured out how to post pics which took me 2 years but it makes it easier to see, for me, them  if they are a bit smaller. ;)     Pat

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.
Title: Re: Bambboo backed bow
Post by: uwe on January 21, 2008, 03:18:45 pm
Why not! It works for more than 150 shots.

Post by: Slivershooter on January 21, 2008, 04:21:32 pm
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

Very nice tiller on that one. How far are you drawing in the picture?
Title: Re: Bambboo backed bow
Post by: tom sawyer on January 21, 2008, 05:33:40 pm
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.

Post by: Justin Snyder on January 21, 2008, 05:35:25 pm
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.

Uwe, that's a fine looking weapon.
Title: Re: Bambboo backed bow
Post by: bootboy on January 22, 2008, 02:58:26 pm
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.
Title: Re: Bambboo backed bow
Post by: uwe on January 22, 2008, 03:00:06 pm
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

Thanks for your comments. I used a german glue called "Bindan Propellerleim". Its waterproofed and the name says, that props of aeroplanes are glued with it.
I read in Germany that some bowyers use it. Another good german glue is "Ponal blau". I have used this too, but the propglue seemed to be a little stronger by name. So I used it. I think that this bow needs a strong glue, because of its highly stressed construction.

@Ekwos: nice to meet you here! I have seen your bow in the last mag. as BOM. Nice work done too. I know the step by step of it, as you send me the pics.
I ll hope, there will be a way for the tendons to come over.

Hello,Uwe, you made a nice bow.
Could you give the address of the makers and the full name of that "bindan propellerleim" ? Smooth-on here in Belgium is very expensive and I would like to find something more affordable. Do you know if you can glue wood and fiberglass with it ass I would like to use it for allwood  and wood- fiberglass too. Thanks.

Very nice job on the arrow, the bow is also spectacular.

Yes, why not! Differnt possibilities. I`ve got it at Ebay`s. There is another shop called "Toplicht" in the www. Equipment for classis ships and yachts. adress in Hamburg:Toplicht GmbH, Friesenweg 4, 22763 Hamburg, Tel.: +49 40 88 90 10-0. e- mail: toplicht@toplicht.de.
Otherwise "Google" gives a lot of info.
Hope it helps!

Yesterday I took a look at ebays Germany. "Bindan Propellerleim" was not found, but as I only searched for "Bindan" I`d found what I wanted: 1 Kilo (?) for 10,??Euro plus postage.
