I really like your magnetic vent damper. Pretty savvy piece of engineering.
Thank you very much... This drum is an opened lid variety with a removable top.
In the picture of the build with the layout lines the drum is actually upside down. divided-circle.jpg
I layed out the geometry on my computer for even placement of all the holes that I needed or thought I may need. I printed out the file and trimmed the paper to fit the bottom of the barrel. From there I made sure it was level and using a string with a weight attached I aligned the string to match the layout lines.drum_string.jpg
I measured and marked upon the string the location of the hole to be drilled and transfered that to the drum itself.
Then, move string to next alignment, mark drum, etc.
