I started to lay out a pattern for a recurve jig and I can't decide on the diameter of the circle I want to use. What do some of you guys use?

I used a 5 gal bucket for one, Bub
-
Probably 6" or more radius. 8" to 10" radius might be better for your first.
-
Wouldn't 6" radius be like a pop can? I was thinking about something like a five gallon bucket but it seemed big when you look at the circle. Wood is pretty cheap though and I can try some different sizes.
-
Radius is measured from the center of the circle to the outside so a popcan would be like a 1.5" radius. A 5 gallon bucket would be about 6" radius......i have also been wondering what size of circle to use for a recurve so im glad u posted this question. :)
-
The smaller the radius the more energy stored by the limb.. :)all things being equal! The smaller the radius the harder the wood is to bend! >:D
-
The larger the radius the less likley to snap the wood. 5 gal bucket is a good starting place. I should have used that.
-
I used the wrong termalology I guess. A 6" diameter or bigger circle would be a good place to start.

I'm doing my first laminate recurve right now...I don't have a lot of hope for it but oh well. I'm using a piece of 18" steel pipe as a form, flipping the last 12" of the limbs.

Mine broke. So much time and effort it's hardly worth it. Maybee wood species makes a difference but I tried to use the 4estTrecker method and I wound up piking the bow. Both sides cracked split and simply broke. I've seen some realy big recurve tip overlays that were glued on . I may try that method next.
My radius was the top of a 5 gal bucket for an 11" section that was pretapered.
