Go with the biggest bandsaw you can afford along with a $5 coping saw for that sort of rare inside cut. I say biggest you can afford because you might need to cut something not airplane related some day. I also do woodworking so I bought a 14" bandsaw and use it all the time on hardwood. However; if you absolutely don't intend to do any larger jobs, then a benchtop bandsaw will be fine. Just don't buy one with 3 small wheels. They tend to break blades. 2 large wheels are much better.
