PearlDrums mentioned my best method. Get it roughed out pretty close to tiller first, then bend the recurves.
The other thing is, I don't love floor tillering. I can do it, just doesn't come naturally. One thing I like about shorter bows, recurves, and mollies, is I can often spread my 74" wingspan, grasp the limbs and "floor-tiller" it by bending it slightly over my knee. Brace the handle on the front of your knee under the kneecap, grab as far out as you can and flex it with a wide-hands rowing motion. Then flip it and repeat.
