Going on forty four years in construction...and during that time I have never been laid off for lack of work. This company will have work until I retire or just get too old to do it.

Pictures show the pvc casing we are bending for the exterior of the arched windows. Bending it edgewise is possible but it tries to flip up at the outer edge, so we keep it under control by keeping it sandwiched between blocking. You have to work it slowly and apply heat as you go.
Also helps to over bend it slightly due to some springback.

Nice job
