over-the-tip stringing

I don't know the particulars of this. Draw force on one axis and draw length on the other? I ended up splitting one tip with the string, so I am in the process of applying deer antler tips before further experimentation. I will try determining that curve after the tips are healed.

Hey, Godfreymik,
It's nice to see someone is furthing the research on my idea haha! I love it! I found the same exact thing in my tests. I found that the longer bows did not improve very much at all but the short ones did a fair amount.
Also I noticed you said you had issues with one of them splitting. To prevent that from happening wrap sinew around the nock in a perpendicular fashion relative to the bow. It will hold those fibers tightly together and will eliminate the possibility of it splitting.
I have one more tip for stringing the bow more easily but it's tricky to explain so I am going to attach a video when I get home tonight

I finished repairing the split tip and added deer antler tips. This lengthens the bow about 3/8". As I didn't think to change the string, the brace was increased by 1/2" to 6" The thing that amazed me is the speed this is now shooting with the same 20 g. arrow. I got 150.9, 149.8, 149.9. Then I must have drawn past 22", because it shot 153.9. A higher brace shouldn't make it faster, just nicer to shoot, right? In any case, I think I will build another with the tips only designed for over-the-tip. Here are some photos and the table of draw length and weight. The tips are kind of mangled due to being changed so many times.

In your last photo, it looks like there may be some excessive string wear. If so, that may be the reason it’s not done on a regular basis.
godfreymik:
Another reason they have not become popular is that they are REALLY difficult to string without an aid. I ended up using a bow stringer on a tillering board. Once the bow is bent, it is easy. Stringing it without an aid is difficult and not fast.
I would be interested to learn how pierce_schmeiche stringed his bows.
