I am planning to do this in 1/8 birch ply. I need about 100mm high cylinder. The outside cylinder I can do but the smaller one, around 20mm diameter, I am not sure what is the best way :
- Stack of cut circle glued together (complicated to make aligned and lots of waste)
- Living hinge glued in a cylinder (too small diameter it seems from my test)
- paper/ other thin material to make the cylinder. (not strong enough to support the inner material maybe?
