- The large diameter of a brodie helmet (the horizontal diameter in the picture) is about 1 foot (or 12")
- The disks seem to be the same diameter (if you want to check, don't forget that the higher you get in the picture, the smaller items become, due to the perspective)
- When I measure the horizontal diameter of the bottom disk on my screen, I have 25mm; when I measure the width of 9 sticks on my screen, I have 18mm. That means that the diameter of the sticks should be 1"...?
- When I measure the vertical diameter of the bottom disk on my screen, I have 18mm; when I measure the height of the sticks on my screen, I have 27mm. That means that the length of the sticks should be 1 1/2 feet, or 18"...?
