With plenty of time before the build starts, consider going back five, six, or more years in the forum topics and start reading interesting sounding threads. There is a wealth of knowledge that will help your build. Create a document in your favorite word processor and collect a list of hyper-links to the threads you want to revisit in the future. Copy the address in your browser's address bar and paste it to your document to create the link. There will be a way to edit the name of the link to something more useful than the typical "https://teamkitfox.com/Forums/newrep...3018&noquote=1" You'll end up grouping threads into categories. The initial reading will teach you a lot about building a Kitfox and your document will be a big help when you want to refresh a vague memory of a tip.
One of my favorite resources was Tropica Tuba's website. He documented his build and included photos of every step along the way. http://tropicaltuba.com/Kitfox%20Project/Kitfox.htm
More to your topic, the first thing that comes to mind is buy a Drill Doctor and become a sharp bit snob! And buy a dozen each of US made #30 and #40 drill bits.
