I use a brass tube for making holes in balsa. Sharpen the inside of one end of the tube with an exacto knife. Drill out 1/8'' deep at a time, cleaning the tube every 1/8''

Kinda hard to chuck 5/8'' brass tube into a 3/8'' drill chuck....
There are many ways:
- reduce the dia at the chuck end of the tube by using wooden dowels
- or Solder progressively smaller dia concentric tubes inside each other.
- or buy a chuck that accepts larger bits.
- or just do it by hand, balsa is soft.

BTW works great on foam too.

Read section 1.3 on my how to webpage. It describes foam but the same works on balsa too
