Got a 66" ttt osage, thinking about flipping the tips, never done it. Could use some advice. How far from the ends and whats the best way? Form?
-
I traced one limb of my recurve on a 2x12. cut out the curve and drilled holes every 4" or so. the farther you clamp the tip down the curve the more "flip" you get. no science to it.
-
I flip the last 6 inches on a form like Kevin's. Love how easy it is to bend osage with a heat gun.
-
Rings are super thin should I strap the belly when I bend it?
Any pics or dimensions on forms?
-
I made a 7" long form which I clamp the tips down after heating them till pretty warm..

I use the same form that I make recurves with. Just hold up on the clamp pressure at the tips so the arc isn't so severe. I'd imagine you could use a plate or pail as a template on a 4 foot 2" by 6" and get the same results. Not a bad idea to bend it a little past what you'd like the arc to be 'cuz they usually straighten out a little while the bow is being broken in.

I don't think you'd need to use a metal strap as long as the edges of the bow are rounded and you heat the osage long enough that it bends willingly. I use square wood shims so the clamps don't dent the belly.

thanks for the ideas, will probably be in the shop giving it a try tomorrow.

I consider "flipping the tips" to be just a little bit of correction to regain some profile from a bow setting as tillering commences. That is in contrast to adding recurves which has a different, albeit similar, purpose.
That said, the process is the same for me. I have several forms of differing design depending on my goals. For flipping, they are maybe 12" long and add 1-1/2" of reflex over that span. Use a flexible ruler to get your curve. I use a 2x6 to make the form.
Here's is a video of me doing recurves: http://youtu.be/SFtMJpMJn74
This form has a notch built into it to hold the tip. Flipping forms don't for me. I just clamp the tip.

Seriously that looks great.
Bill
-
you really FLIPPED those. looks great
-
Beautiful bow!!!
-
Bill thanks for the compliment, the stach is my trade mark. it goes on the bow when I,m done
Karrow, i was nervous as heck doing it, made the form and just done it, go big or go home I always say.
4runr, thanks , I still have to back it yet, and make a string. This bow is probably going to go to a good friend of mine. He just don't know it
-
that is one really great bow- i'll be your friend :D
what are you planning on backing it with?
-
Why are you backing it?
-
Pat, it has super thin rings. Just the process off tillering has made a few spots look a little stressed.
-
Wow that looks awesome and tiller looks spot on. Congratulations!!
-
Bingo
-
what are you going to back it with?
-
The best way to learn is to just do it.
Looks awesome
-
Fujimo, got some raw hide for the back, my next day off I'm gonna turn the heat up in the shop and get down to it.
-
One heck of a nice bow!
