"your welcome to take the point away"
No need to take the hump Brian.
Just think a little more about what it is that you are trying to tell us and show us.
Remember; a picture tells a thousand words😉
Cheers, Doug 😎

Hi Brian,
Very pleased to see that you decided to go for an 8mm tube👍
That leaves you some 'meat' to play with for bushes/bearings😊
If you use a 6mm running tube with a 4mm drive shaft, as some have advocated, that only leaves you 1mm to play with for outer tube and bearings. Not a lot☹️ Resulting in a comparatively flimsy arrangement that I would only want to use for very short shafts at low revs. If at all.
Personally I would regard 3mm as the absolute max diameter of a shaft in a 6mm outer, and then only for short e.g. >/=6" or so shafts.
That's my humble twopenn'orth anyway.
Wonder whose shafts / bearings will last longest 😁
Happy building👍
Stay safe🤞

I heartily agree Martin👍
Such text posts are pointless (apart from ranking points🙄) without the associated pics and some explanation of HOW!

Brian, some set-ups use a small washer, then a nut, last a threaded prop. Other set-up is the washer, then a “Dog”, a prop then a lock nut.
Hope these images help.
