Hi, Matthew -
Should I change the thread title to:

Drum Suitcase: Any Tips?

or

Suitcase for drum: any tips?

From the thread title, I thought you wanted to make a drum out of a suitcase, but your message seems to indicate you want to make a suitcase for a drum. I was thinking maybe you could use a cardboard barrel. They come in a variety of sizes. ULine is a good supplier.
