Is it worth it

Sinew backed with a bamboo belly.

I never tried that,, sounds interesting

Been done many times.  Because it's a good combo. Heat treated high quality bamboo surpasses wood in compression abilities.

Sweet!!! What about for a 46" D bow

[stuckinthemud]

I think I read that the bamboo needs to be charred black when you heat treat it??

[Hamish]

I think the charred black look is overkill, from the days before heatguns, where people used blowtorch set ups for tempering. Not necessary to go that far and you still gets the performance results.
 If you are not already aware you only temper the belly lams, not the backing.

[Swamp Thang]

Haha yeah I'm aware

I am wondering I have harvested 8 deer leg sinew plus some from the butchering how much do I need for a bow 48" long 1.75" wide

[Swamp Thang]

Also how much is to much sinew, soft wood bow with boo belly

[Swamp Thang]

Slaughtered and quartered a steer snagged me some sinew and the hide been scraping for three days now but got some thick long sinew more than enough for 2 more layers of sinew plus a string... I hope

[Swamp Thang]

Okay question sinew backed this bow and within a couple days I've noticed it's deflexing not relfexing what did I do wrong you think?

[Swamp Thang]

Also how might I rectify

[willie]

if you have another slat or scrap of that bamboo, you might try putting a moist cloth or something on the same side as the sinew was applied. look to see if the moisture creates the same effect. my guess is that it will come around the way it's supposed to when it gets a bit drier. did you toast the bamboo before applying he sinew?

[Swamp Thang]

Haven't put the bamboo on yet looking for the right piece it hard to find the larger sizes down here

[Swamp Thang]

Pretty sure it is the moster that's got in the wood but I'll not sure.
