Bearings....?

[R.G.Y.]

As members who look a my posts will know I have lots of rubbish. I use old sealed bearings from drills. Super glued to the shaft and held with a metal or wooden housing screwed to hull Geoff

Hi PDs
I was re reading this thread as I'm trying out simple bearing ideas before I go near my hull!!!  My shaft will be 5mm silver steel, so I tried 5mm bore universal coupling ends, but the shaft won't go through.
Then had a go with some 6mm brass tube, (5mm tube telescopes into this) shaft goes through fine, but with a bit of play, I think because the tube is thinwall.
Obviously the play is tiny, but not sure about using the tube because of this.
Thinking about trying to find some 6mm tube with a slightly thicker wall, but will still allow free rotation of the shaft....any ideas/suggestions anyone?
cheers

One thing to beware of Clark, silver steel can rust, so it could seize up if the model is put into storage for a while!

Personally I'd change it to stainless steel, or brass for the shaft...

Thanks for that, Eddy, Good advice.
I had the silver steel (at least thats what its labelled) lying about, so have been experimenting with it.
I will try stainless or brass and see how the fit is inside the 6mm tubing.

you can buy bronze/brass pre made bearings from some bearing retail out-lets , but i normally make my own on my lathe, i secure them in the hull sides w araldite , or i fit them into small prop tubes, but i have noticed some wear , as the paddle wheel is large compared to a prop, and intend to do the next set in bronze .
 last one i did i basically turned up bearings same as a prop tube , and glued them into ply up-rights , no outer prop tube ,all mine are fitted w a oiling tube
