Hello all,

in the pursuit of trying something to make my ship sail at a more realistic speed I've purchased a 3:1 gear box. This came in the post yesterday and its size is perfect for the slender lines of my ship (Build Blog HMS Curzon) I was now wondering if I need to construct an oil sump for this gear box? it's brass and Aluminium construction. Any suggestions welcome.

Thanks

Dave


Best Regards

Hi dave
did the unit come with any instructions re lubrication? Can you post a pic? My home made gear boxes all ran with a light oiling on each sail.

Evening Dave,

I've attached three images, no instructions on oiling were in the instructions, I could ask the supplier (Maritime Models) he's been very helpful and quick to respond to other questions I've had.

Looking at the box again I could create something that would hold (and hopefully) contain a small amount of Gear box oil.

Best regards

Dave

Looks to be well made. I would ask Maritime as they may have experience of using the unit. It rather looks like the gears are carried on brass/Bronze shafts with similar bearings mounted in the ali side plates.
Whatever you use you will need to keep any grit etc out of the mechanism. A simple removable plasticard cover would help.
A spot of light machine oil (not 3-in-one) on each bearing before each sail would be my guess. Sewing machine and model train shops sell light oils.
But do ask the supplier.
Cheers
Dave

Are you sure it's aluminium and brass? Those two hate each other, especially when even slightly wet. But I have one of those little jobs and the silver coloured bit is tinplate, but as Dave says a good but careful light oiling at each sailing will be ample.

I agree light oil would be good. If you can make a cover it will not only keep grit out, it will also reduce the noise.


Happy sailing.

John.

Hello, I do not know if it's good to put an oil bathtub in the boat. I think it would be enough to use the grease that they give to the racing car models. I used it a few times and it was great. Grease stays on gears and is not thrown away. Then only the cover of the gearbox is sufficient to prevent the ship from being accidentally wiped. But I prefer to use 6V power motors for 12V and 24V instead of gears. They then have a low current take-off and a small turn, and yet have sufficient force for the bigger bolt. Zdeněk

Hi Inkoust
I think we have already discounted an oil bath.
Sorry but grease should never be used in any gearbox unless it is completely enclosed as any dirt or grit that gets into the grease will destroy both the bearings and gears.
A light oiling before each sail will provide all the lubrication required.
