Hickory backed bows always perform poor. Its a massive difference to the same bow backed with boo.   

Very interesting find! Why is that? Why would a hickory back be a poor choice? Does it take tension set (assuming that’s even possible)?

lots of different kinds of hickory here in the US, and densities vary widely. Lumber grading is mostly by appearance rather than structural strength. https://www.extension.purdue.edu/extmedia/FNR/FNR-285-W.pdf
A bowyer sourcing top end hickory in the states would most likely not source from the lumber retailers.

Nice collection of hatchets and axes, Clint. Aren't most of those carpenters and roofer's hatchets?

Yes they are Pat.  I like the small camping style hatchets better.   I’ve got a lot more in the garage.  Maybe when I retire I can start restoring them all.

Bows / Re: Common mistakes in deflex/reflex bows?
« Last post by Tuomo on December 14, 2025, 10:35:44 am »
I think the biggest mistake is having too much reflex (tips bent too far behind the back). The second mistake is not using the VirtualBow program to model the bow and find the correct taper rate for a specific front profile.

In my opinion, and what I prefer to do, is keep the reflex at about 0–50 mm—no more in normal bow. If I want to make a flight bow or a bow just for speed, and I can trust my materials, then more.

I always make deflex–reflex bows as laminates, because then the correct taper rate for evenly distributed stress is easy to achieve. Usually, a taper of 0.006 or 0.008 works well. I have a good taper sled, so the tiller is almost always spot on. If the tiller needs correction, a scraper works well and is almost the only tool I use.

This is very nice bow! I wish I had good quality yew!

How long this bow is? What is that dark area under the black nock?

Tuomo I really dig your D/R design. Would you be willing to share the parameters here?

Here is VirtualBow model file, and measurements of the bow number 6.
