6 piece Asiatic style bamboo bow

So update. I did an autopsy of this bow and discovered the reason. It was my mistake not the wood in this case the top boo strip that failed. I had filed down the top sections of the limbs at where they meet up at the handle to place the top piece onto violated the top limb integrity and it popped off.
So in the end my mistake and will not make that mistake again.
Here’s a pic of where it pulled up

Update on this little bow. I made new set of limbs and tapered thicknesses towards the tips. I measured as carefully as I could and measured every 2” along each slat of boo. Glue up and put about 2-3” reflex induced glue up. Used stretched bicycle tubes to hold together on glue up. The problem I noticed with using tubes is that it introduced a bit of twist. I had to shim and straighten them up and then we’re fine. Assembly was hot glue method as before. Tillered to about 26” then put a thing on it. It’s about 45lbs. Brace was still low at around 5 3/4” from string to belly at deepest spot. I then did a few more scrapes and sanding to fine tune the tiller. It all went pretty fast. I still had to remove more then I wanted from the belly in scrapes. I lost about half of the reflex as expected so far. Have a look here a few pics. More to come…

Sorry forgot to mention. It weighs 450grams at the moment which will likley end up around 400grams when I thin down the and shape the siyahs. Gonna wrap it tomorrow and shoot it a bit and post another update.
Thanks for looking
Cheers

It looks great. congrats. It's pretty amazing how thin the limbs need to be for 45#. Looking forward to the rest of the build and shooting results.
