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)?

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.

So to drop down on that further, how do you ensure that? Tiller only with a scraper? Some other stratagem?

Very Cool, very classy. I rarely see horn nocks on a flatbow, I thought I was one of only a few that does it. They look really good, especially with yew.

Great attention to detail. I really like it.

You make sure the reflex is even thought the bending portion of the limb. Whe you bend the limb, you make sure the bend stays even as it straightens out, eventually becoming a straight line as the limb flexes flat. After its a straight line, you make sure it bends evenly into a perfect curve as you pull it through towards full draw. You set yourself up for success by evenly reflexing the bow. Start even, finish even.

Biggest problem is over stressing the limb. A limb will always have a specific amount it can bend no mater its profile. Make sure the bend radius never is exceeded.

A few forumites have mentioned already how difficult it is to not create a hinge when tillering a R/D design. How would you go about actually making sure the bend radius is never exceeded?
