Prop Shaft Support and Water Scoop

Here is best explanation of a stuffing box Harbor models is in California but I would think Cornwall models would have it. Harbor models makes them and sells them. https://www.harbormodels.com/shaftstuffbox.html
there are also stuffing box adapters you can buy that clamp around the prop shaft. that can be used being as you have installed your shaft already, also might think of putting a nylon washer at each end of your prop tube to act as a seal

Prop Shaft Support and Water Scoop

Hi Neil,
It is not a silly question, As different people and countries call things differently.

Nylon "Net curtains" if that makes any sense.

I have also used bandage (First aid) material with slow setting Araldite as it soaks in to the cloth.

If it looks right it probably is.

Stuffing box is the outside unit glue or epoxied into the boat that the prop shaft runs in.Silicon grease is used inside the stuffing box to help keep water from going up the shaft .

Thanks for the responses and still like the idea of car filler as bought some for the task ages ago. I will be looking at the different glues and fillers mentioned though.
One small question what's a stuffing box?
Also wondered if I should have posted this photo as well with the mention of making it look like the keel is holding it. As the keel would now look as if its in two.
Cheers and be safe

Although I think your wood support is very good, I use Stabilit express glue on all water tight areas such as this. A little expensive but reliable.
Peter.👍
I cannot promise to finish one project before starting another. I know, I tried.

Can you make an angled piece and slip it under the stuffing box making it look like the keel fixing it in place.

Hi Neil,
I've used Araldite for a long time and had no problems at all. P38 is equally a great space filler. As a strange add on, I've also poured liquid Silicon mould maker around the rudder post (Something like GP-3481F or a cheaper brand equivalent), Prop shaft entry and water scoop inlet area to not only provide a great water proofing, but it also worked to quieten down vibration sound travelling through the hull - it damps a lot of things and the softer grades don't adversely affect buoyancy or add to flotation issues. Just remember to plug the water inlet to make sure no silicon goes down the tube.

Hi Neil,
I have used isopon p38 car filler and had no problems.
I have also used Araldite to glue mounting blocks to the inside of the hull to take the RC equipment again with on problems.

If you want to add a little more strength you could add bits of nylon curtain and cover with ether car filler or Araldite.

Hope everyone is safe and enjoying lockdown?

I've been away from this for a while but would love some advice.
I had major issues with the prop having to remove it with great difficulty. But after some excellent advice and it being sorted thats were it stopped. I may have some time now though between work and decorating jobs from the boss.
The last advice I can remember is that I needed some form of stiffening on my shaft 😉 which I believe was just to use car filler to fill the gap between the hull and the prop shaft. Wasn't quite sure how to achieve this so thought I could place a piece of ply to provide some support to the shaft but also to build the filler up against.
What do you guys think?
Also I purchased some new remote gear with a water cooled speed controller. A new water scoop was purchased and wonder if its in the right sort of place. Also would fixing it in with araldite be OK as the threaded section doesn't go all the way through the hull. I still have the original but think its long now the angle of the shaft has changed.
What do you guys think?
The rudder and serci is a different matter and a question for another day.
Thanks and stay safe 👍
