golden chain tree take down 53/28 (No. 21)

[Zion]

That is AWESOME! Never heard of that wood but that thing is COOL looking! You make some sweet bows man!

[nathan elliot]

Just cant beat a bit of Laburnum. Nice man!

[simson]

Thanks fellas for your kind compliments.

Will try to answer some questions

Finish: homemade oil mixture of several ingredients (somethingg like danish oil), this stuff hardens out.

Hollow limb design: it isn't such difficult to do, just leave the 'edges' round to get not to much stress there. Thickness here is same as in middle of limb. See here:

http://www.primitivearcher.com/smf/index.php/topic,34898.msg459925.html#msg459925
here on PA were several interesting discussions on hollow limb design
this is the most extreme hollow limb design I did so far

Laburnum: don't know if this wood grows in US, I have goggled the name for it ...

Overlays on ahndle and tips: are not at working parts of the limb - so I do not expect any problems of that


Thanks again!

Laburnum is Golden chain tree or Laburnum anagyroides. See this thread- http://www.primitivearcher.com/smf/index.php/topic,16446.msg226024.html#msg226024
Are you in Germany? Some really good Laburnum in Germany-

[rhansen]

Wow, awesome bow!

[missilemaster]

Dang.....................not much more to say!!!!!

[Josh B]

Beautiful bow Simson!  I got all excited thinking I have one of these trees in my yard that needs pruning.  But alas, my tree is a golden RAIN tree.  No where near to even close to the same thing.  Once again, beautiful bow sir!  Josh

[danny f]

You may not expect them! I understand what you are saying but trust me it is risky. I've been there done that and have the t-shirt. I'm not just spouting
Have you ever tried spliting labernum?
Laburnum anagyroides is the latin name.

[Pappy]

Beautiful work,very cool bow for sure.Hollowing had to take a lot of time and looking like you have done a nice even job of it. I have to agree on the tips,but that's just me.Hope that don't give a problem. Nice job.

O.k. we will see if it holds together. No risk - no fun. Anyway thanks for your advice.
btw. this not laburnum anagyroides, but laburnum alpinum. But I think there is not much difference in wood and behavior.

Nathan I have seen some of your great bows on PP! This made me hungry on laburnum. Could you please say something about the qualities of the sapwood? On your bow above is the complete sap on, wright?
And yes, I'm in Germany.

[Christian Soldier]

Great work man. Very inspiring. I've got to try making one of these takedowns now. Any advice?

[mikekeswick]

Labernum sapwood works just fine in tension. You have to be careful not to use the sapwood if there is any hint of a black line between heart/sap.
Labernum works just like yew, the sapwood is lower density than the heartwood and can give a mildly lower limb weight than an all heartwood limb.
I personally rate labernum at least as highly as the best yew. Here in England it is hard to get yew with good density (not impossible ) but pretty much all the labernum has been high density. It will make the heaviest warbows just like yew and can handle the same cross section. Labernum is very elastic and has great compression tollerance but also just like yew low bend resistance.
