I would never go smaller than 4mm (1/8”), or wider than 6mm (1/4”) and 10 mm (3/8) BS blades. Manufacturers may say their BS works find with 3mm wide blades but breakage pretty common. It may be true of 4mm blades too! Not sure if operator did not set up BS correctly or tried forcing wood, or too many teeth per inch blade.
Depending upon radius and size of wood to cut also whether wet or dry will find 6mm, 10mm, and 12mm with right number of teeth per inch TPI workhorses of bandsaw box world. Depending upon availability 3, 4, and 6 teeth per inch with hook, or raker set blades should serve you well.
PVA white or yellow glue should work well for glue ups. I like Elmers and Tidebond II sold here in U.S.
