Homemade Cookie Tin Banjo, part 2

..
It seemed to me that putting screws thru the drumhead to secure the inside part of the neck would tend to dampen the vibes of the drumhead, or effectively reduce its size.

I thought there should be a way to secure the neck on just the sides of the cookie tin.

A banjo usually has an animal skin stretched very tight over a frame and there are provisions for tightening it. Modern commercial banjos use a system of about 20 fancy screws around the perimeter, the tension can be adjusted to exquisite perfection. (And they probably use some synthetic animal.) Homemade ones usually just stretch the skin over a wood frame with tacks, and depend on the natural shrink process of the skin as it dries out to tension it. On cold foggy days the banjo has to be warmed by the fire before it will sing, I 'spose, like a drum.

The bottom of a cookie tin is just a sheet of metal, humidity has no short term effect on it; it's held nicely all around by a crimped seam. Why destroy such a perfect setup?
