Chad, I do not use 5 minute epoxy for anything. It sets so fast I can't get everything positioned and clamped quickly enough. I use 30 minute, clamp it, clean up the excess, and leave it alone for 24 hours.

I'd start with a 1 ounce bottle of thin CA. If there is a Hobby Lobby craft store in your area they usually have half ounce and one ounce bottles and the prices are similar to most online sellers and hobby shops. They also stock a limited selection of balsa, basswood, and ply. Nothing big, but at least a possibility if you need to make a new part or two.

You could do most of the build with white or yellow wood glue like Elmers, Titebond, or other brands available at Home Depot, Lowes, or Wal Mart.

You can get things like sandpaper (when you need it) at Home Depot, Lowes, or Wal Mart; so no reason to mail order it.

You will need pins to hold parts in position. I like the hobby store T-Pins but sewing pins from Wal Mart will also work.
