I noticed that props and shafts seems to be popping up in different subjects again. As it has been a while and there are new members on model-boats.com, perhaps this should be discussed again. As usual, chime in with your opinions.

Some of my boats (usually kits or RTR models given to me by others) have factory made shafts and props.

My focus here is on home made shafts, stuffing boxes, and props.

Seems some people go to a great extent to make the shafts and stuffing boxes (materials, bearings, etc.). I make my own out of copper/brass tubing (usually K&S) soldered together. There is a gap between the shaft and outer tube filled with Vaseline (petroleum jelly). I also added a filler tube near the motor end. Make your own length. Simple and no leaks over all these years.

As for props, the last few I designed as 3D printed them using ABS. Sure, I can't get a high polished brass finish on them but then I haven't seen many ships with that kind of finish. Virtually no expense, just time. If I want more, no problem. I probably spend less time in making a prop than searching for one. Two, three, four, five blades, whatever. ABS is tough but I can always print another. Not to mention replacing a lost prop.

Anyway, that's my opinion.
