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.
John thanks for the link, I am now subscribed to your chanel
well I went and done it. Worked out ok.

Warren, Did you use that stache as a caul?
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!
