aceteal (probably spelt wrong!) a type of plastic, water lubricated, and tap in to the shaft ends. Easy to fit, easy to change, and very very cheap. I get mine from shg marine, come in various sizes👍

I make my own prop shafts.
If you do use steel bar you will need to service the shaft frequently as it will rust inside the proptube. The real problem is the rust may damage the bearing when you remove it to clean.

If I can I use 316 marine grade stainless as it is more resistant to rust in salt environments. 303 grade will work but in my experience shows signs of rust over time, especially if your water is saline.
I have used phosphor bronze but you do need to check the specs as suggested above. Some can be exceptionally hard and may cause wear to the shaft.
Acetyl is very good but it comes in two variants and I have found Delrin to be more resilient and just as easy to machine.
You can read details of the two types at https://www.directplastics.co.uk/about_plastics/why-choose-a...

We actually used a type of white Nylon on our six club model tugs which have been running since 2007 at shows where we give the public a chance to have a go. Some of the motors have required replacing but the bearings are as good today as when first installed.


Live long and prosper

Hi Ed, sorry 🤔 occurred to me later I should have posted the link!
http://www.shgmodels.com/acatalog/
Download the catalogue and you'll find all the info.
The other page links are useless, they only re-direct you again to the Download Catalogue.😲
Otherwise there is no useful product info on the website 🤔
Cheers Doug, Happy Tugging 😉

HI Ed, long time no speak. If you want up-graded prop shafts, have a look at Raboesch, they do shafts with roller bearings and great seals, look on their site , but , order from either Deans Marine, or Cornwall Model Boats, expensive but truly superb

Hi Mark

Yes it's been a while!
Had to keep the house.
The wife wasn't feeling well!
She's doing much better know!

I finally have a project I'm working on!
It's the Brooklyn Tugboat by Dumas.
I ordered the Prop and shaft by Dumas 3 weeks ago.
Still waiting for it!
When I saw Doug, RNinMunich talking about shafts that's when I asked about them! I could've ordered somewhere else!
Hi Doug! Thanks for the URL's, I will bookmark them!
