I use Ricks Traditional Bow Strings on all my custom bows now and he makes a decent flemish twist. Kirk

Yes, get this, I changed to a B-50 from FF and not only was it quieter on said bow, it was 3 FPS faster on average. Go figure!
Unfortunately that can’t be figured, because it defies physics. A modern FF string will always be faster than Dacron.
Did you get your post backwards here? Kirk

Kirk, I did the SAME EXACT THING with an osage selfbow that I built. Are you really going to start down these roads AGAIN???

I just thought he got that backwards. Didn’t mean to offend anyone with my opinion. I have no experience with self bows. Kirk

No matter, 3 fps does not define me as a bow hunter, or will prevent me from a kill. 3 fps is basically nonsensical brain fodder, like so much other stuff I could list and piss people off.

Calling out members as a Sponsor???? Are you trying to self destruct?
:banghead: :banghead: :banghead: :banghead: :banghead: :banghead:
Absolutely not trying to self destruct... Wasn't my intention to call anyone out. It just seems really strange having a softer dacron string transferring more energy to the arrow shaft than a fast flight string. Never heard of that happening before.
Very cool looking self bows there. That is an artform i've never spent much time with, but totally appreciate. I've got an osage stave with the rings chased on the back that has been sitting on a shelf for about 12 years now. I suppose i should pull it out and finish it some time. Kirk

Bet it darkened up a good bit in color?
Start a new thread in the bowyers bench section if you decide to start working on it, we can help you along if you need any suggestions tillering it out.

Needless to say I still have both 22 and 21 years later. Maiden Voyage and Bear Nessesities were 53 n 48 pounds respectively at finish. By now I'm sure they are 3 to 5 pounds heavier.

12 years old, damn Kirk that otta be a great stave for a self bow.

Thanks Roy,
I have known a number of bowyers that were really into board bows, and self bows over the years and I’ve got the basics down. I’ve actually built a couple lighter weight self bows from yew staves years ago, and built my own draw knives and scrapers from old planer blades.
Time consuming tillering process scraping and sanding the belly and exercising the limbs…. But it was a good experience learning how to manipulate where the limbs bend, and the effects it had on how they performed.
The same theory applies to glass bows for balancing the limbs, only it’s achieved differently, or should I say “ it can be achieved” if the time is taken to actually tiller the bow. But that procedure starts with wedge configurations and taper rates to determine where the limb bends, as well as the shape of your form well before you lay up the limbs. Then mounting them on and adjustable riser to maximize your limb pad angle.
You are right Roy…. Anyone can lay up a glass bow and have it shoot arrows. But building a well balanced, smooth drawing bow that has decent performance requires years of experience. Starting with self bows is an excellent way to learn how these things really work and makes a true bowyer out of you.
Most glass bowyers come up with a limb shape they like, lay up the limbs, get the limbs aligned, get their width profile ground, and their tillering process is nothing more than sanding glass until the tiller measurements at the fades or riser are even, then call it good. Very few bowyers I know take the time to actually tiller a glass limb bow and balance the limbs properly and wonder how come some bows have more vibration than others do and don’t perform as well.
There are tillering tricks that can be used to fine tune glass limbs too if you don’t mind taking the extra time to do so……
Now you guys got me going on this self bow project. I’m going to have to pull out that Osage stave out and blow the dust off it….. Kirk

Limb mass vs arrow weight? Limb travel distance? Lower pre load at brace ? Is it a self bow thing? It makes my head hurt thinking about it…:biglaugh:

Don't have a clue why b50 was faster but it was. And of course quieter, although either was quiet enough for hunting as selfbows are inherently the quietest bows anyway.
Also was called crazy for stating one particular arrow shaft allowing me to shoot 150 to 225 grain heads off of bows ranging from 58 to 78#s. But others soon found out the same validating I had 'defied physics'.

after many years of bow building I still get one now and then that just fights me all the way though for no good reason at all. No rhyme, nor reason detected , or ever figured out why….. “Some times you get da lion…. Sometimes da lion get you.”
