Hiya, it is funny you bring up this subject, I had the same thoughts last
week. I'll just tell you my conclusions, you do with them what you want
I first thought my axles should be 20mm, so they would fit my wheels. This
is serious overkill in size, and did not seem practicle for the following
- The hole in my hull would be big, and my bearings would make the hole
I decided to reduce the size to 12 mm (around 7/16") which gives me
smaller bearings, and less work drilling holes in my sprockets. I make
sure my sprockets are tight on my axle by: drilling holes in the sprockets
and fitting in tightening-screws. I'll indent the axles for extra grip.
Then again my tank will most likely be totally different from yours: I
use big wheels, and I am building an Amphibian, which means WATERPROVING
holes through my hull.
Good luck on figuring this all out!
