Small night on the build. I took my time to do some final sanding on the large 2 1/2" hole to get the fit of the Aerolab unit just right.
Next I used the stainless steel template to make the 5/16" hole for the safety release button. I did not use a drill bit for this hole since I have already cut the 2 1/2" hole...., however the stainless template was a great guide to open up that hole with the use of files and the dremel.
