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.
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.
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. Dave
