Please keep in mind that even if your canopy on the table is held 100% straight and without any twist, there is no guarantee a perfect fit unless your fuse/longeron are 100% straight. Putting it on the Fuse and locking it in place, might yield a better match to the fuselage. The sanding portion and finish product perhaps can be done on the bench which I did to get the fairing to the near paint ready stage.
