G'day all. I'm making a wooden card type line winder for my Rok as the halo just doesn't fit into my bag well. I have made some templates of different styles ready. I am wondering the thickness of ply to use? I have options of 5mm, 7mm, 9mm and 13mm. My guess would be 7mm (9/32). My designs are between 250mm (10") and 330mm (13") long.
Thanks.
