I don't hand form my blucor wings.
I built a device to roll them around.
Its a piece of 3inch pvc with a sheet of metal roof flashing screwed down the length of the pipe.
I simple cut my wing to size, insert the leadedge into the bender and then slowly roll the blucor up like rolling up a roll of carpet.
It ends up trapping the blucor against the pvc and uses the flashing to hold it in place.
I usually roll about a little over half the chord and then hold it there for a count of ten.
Then unroll and wala, instant blucor wing.
Then I take a heatgun and run over the entire wing, top and bottom to gently sear over or heat temper the plastic covering, this adds alittle stiffness to the wing, without the weight.
Hopes this helps.
