When making my Bluecor FFF planes I roll the wings to get the airfoils. I have 2 fixtures for rolling the wings,
1. From 2" PVC pipe with aluminum siding trim material attached to do the first roll. 1/2 turn puts in the first roll
2. From 3/4" EMT electrical tube with aluminum siding trim material attached mounted in a frame with cranks. Turns a 1/4 turn to put the lead edge curve on the wing...

For smaller models will be making the same type of devices for split bluecor.
will be trying smaller diameter pipes, like 11/2" and 1/2".
