NICE job! You have a working solution to this problem👍

Forgive me... but my mind immediately went to why not make (or buy)
some larger feathers to fit the Pneumatic drill hole and maybe some
smaller feathers so your battery drill could use a smaller drill hole🤔

If I'd got the Trow & Holden feathers they would have been as-described
and I could use a 10mm drill

(/f (expt 10 2) (expt 14 2)) ;; 0.5102040816326531

Half the area and volume drilled.
