When you get to the point in your bow making journey where your reflexing and recurving you can never have enough jigs. I have a few full length cauls that are all for different lengths and style, and also a few different recurve jigs. One that I recently made is one of my favs, it's got a nice sharp recurve and a nice curve for reflexing the limb. I like to start with a steam or boil for my tips, bend it in the jig, then continue heating with a gun and clamping up the limb as you go.
For recurve jigs make them long, it helps with them lining up and you can even recurve and get out some propeller twist at the same time.
