well yes, to technically finish the bow did not take long at all! the finish work sure took way longer!!
heat-treating rattan is no problem at all; just a few minutes with the heatgun and it bends! i heated it some more when it was clamped down and worked on soon as i could touch it.
the recurves are ridgid, so they wont be pulled out!
in germany rattan (also called manau) is available from archery suppliers.
i had seen a guy with a similar bow with a cable backing, looked pretty much like an inuitbow. thatone had around 50# and he was happy with it!
thanks again, frank
