Finished match drilling the F830 and F831 front seat floors to the longerons. Also separated and deburred the F830B-1 floor stiffeners. Then worked on the fuselage rotisserie. Spent nearly 6 hours on this project –still need some AN3 bolts (long ones) to bolt the fuselage firewall to the rotisserie. However, my back says this is going to be well worth the time and effort spent. Only logged time worked on the bird.—.5 hr.
