All Bamboo Hill Style
« on: April 19, 2026, 06:23:02 am »
This is my take at the fancy all bamboo Hill-Style bow.
Not yet sure what to think about the all bamboo thing. Somehow feels and shoots like a very soft yew.
Got massivly underweight also - thought 16.5mm would easy make that ordered 60# bow - I was wrong and only got 40#.
Will start over with 19mm and do more intense heat treating.

cheers

the limbs are made of 5 layers of boo while the grip is black locust.

All bamboo makes a nice looking bow. Maybe your next try will meet your intentions.  :OK

Did you use commercially available boo lamelles for your core laminates? If you did this may be why your bow was under weight. Like Willie's article mentions it can be unevenly distributed power fibres.

For best chance of success I would heat temper the core and belly slats, glue up with a slight reflex.

If you go to a lot of trouble you can split, and glue up narrow sections with high content power fibres into a belly slat. Its a lot of work.

For the commercial boo slats my results were exactly the same as your description, like soft yew. Very pleasant to shoot, light in the hand, but took more set than I expected(I only made unreflexed bows at the time, so a little reflex would have been a good idea.

Well done man! That's a nice looking bow even coming in under what you wanted. I suppose you would pre-tiller the bamboo before gluing like a deflex recurve? I've tried some of them with the native wood we have here in NZ with mixed results haha.

What glue did you use to laminate the limbs if you don't mind me asking? I've tried smooth on ea-40 and titebond 3 myself.
