Sorry still sending only half the message. Don't know why. Mountfleet Models once produced a Chariot kit. This is R & R Engineering's drive unit for it at £290. The picture of the unit might give you some ideas. Good luck .

Sorry Jacko, for some reason this website only sent half the message. Look at this website (it does exist )

Hi Jacko,
I've had a look at the Lego sub and the chariot MK1 diagram. Under normal circumstances a simple prop tube assembly glued into a sub would be sufficient as there isn't enough water pressure to force water into the body if it is surface running and the prop shaft is greased. However the chariot had contra rotating props. I can't imagine how to solve it. The Lego system is novel but I would worry that if it hit a submerged object in a pond the prop assembly could get dislodged. Don't let me discourage you as I'm sure there is an answer out there somewhere.

Hi Jacko,
Can you expand a bit on why you need a magnetic drive? The reason I ask is that subs use a different method to keep water out of the waterproof cylinder whilst driving a propellor.
Best wishes Tim

Interesting project. Modern neodium magnets are much used to hold tops in place and are very powerful so may improve on Colins attempts some time ago.
You can buy magnetic clamps for lathes to hold work so I suspect a similar set up might work. You may have to set the magnet in place when the shaft was stationery but once attached these magnets are very difficult to separate.
Another project to consider should the present unfinished models allow.

Hi Jacko, I have used a magnetic drive disc to propel a small model car experiment for Rolls Royce at college a few years back.
Main problem with this system is find strong enough magnets that are small enough.
Then there is the issue with the distance between the drive magnets and the driven disk, which didn't work well with any shielding between them.
We only managed about 20% efficiency. So the experiment was dropped.
Cheers Colin.
