There is also an additional weight savings since you won't be using any adhesive to adhere microfilm to the framework.

It includes a chart relating the color to the thickness. Bill also weighed some MicroDyne microfilm and you can use that weight along with the chart to estimate how much a given color of film should weigh. His weight puts red violet film, which is slightly thicker than straw brown, at approximately 17mg/100si. Silver film should weigh 10-12mg/100si, or about a third the weight of the lightest Y2K2.

I think it would be a great online resource for builders and lurkers, not just today, but in the future. I have converted it to a text document, with just the names and dates, not the links. If there was interest and permission, I could post it to the Files section.
