8. ACA D Winchester8 Top of the arch ” R=14.5” D = 29 R = Radius D = Diameter Spring line

9. ACA D Winchester9 D = 29 R=14.5” R = Radius D = Diameter R=14.5” Springing board Pivot point Centre for the fishtail gig stick Dry wall screws used as anchor points

10. ACA D Winchester10 gig stick with fishtail Template Stock Slipper Angle Mould
