-I mounted the spinner back on the plane and fitted it up and checked for wobble. -Removed the cowl to allow more room to work on the spinner and backplate -After some adjustments I used cleco clamps to hold it firmly in place -Drilled the backing plate attach holes (14) with #30 drill -Layed out the support plate holes and drilled with #30 (6) -Countersunk the support plate holes for flush #8 screws -Drilled out all the holes to #19 for #8 screws -Deburred all the holes in the metal parts -Started attaching nutplates to the support plate when I ran out of time
Spinner clamped into place-point of no return
All 20 holes drilled evenly spaced across the circumference
