 So a while ago, I was working on this boat and I had to make bearings for these propeller shafts to go through down here. I've got one for pedals and then another one back here that has a motor. Now for the bearings, I was deciding between having a rubber sleeve like they usually do or making plastic roller bearings. And I ended up going with the plastic roller bearings and I guess the point of this video is to give you an update on how they're doing. They're doing spectacularly. I've gone at least a couple hundred miles in this boat so far. Not super far, but you know, definitely a test. So these things have been running for hours at a time and no problems at all. And when I built them, I made them a little bit loose. This jiggles a little bit in there so that any sand bits that get in there can go through without getting crushed into the plastic. And I have a couple little holes up here that let water run through. Hey, let me just give you a quick drawing of what all is in there. Oh, I should mention that one of the reasons I thought I could get away with the roller bearings is because the boat is not always in the water. If it was always in the water, I'd probably go with the rubber sleeve. But usually it's out of the water so it's not going to get barnacles, you know, gumming up the works. Alright, I've got my propeller shaft and then back here there's the propeller. And then right here there's a ring and then here there's a bunch of rollers and those go all the way around. And then here there's a PVC pipe that's covered in fiberglass that goes all the way up inside. And then on the inside of the PVC pipe is another ring of slightly smaller PVC that goes around and that's glued in really well. So the rollers are held in, they're held from going this way by this and they're held from going that way by this. So that way if you take the propeller off and pull off this ring you can pull out all the rollers. And there are a couple holes up here that let water get in and it runs through and out there. And yeah, I've had no problems with these at all, they work really, really well. I think I'm going to use these more often so anytime I have any spinning underwater stuff I'm totally doing these. But like I said before, I don't know if I would do them on something that would be permanently underwater. Because then it might get barnacles growing up in here and mess things up. And there is a video of me making those from scratch somewhere in some fairly recent boat making videos. Awesome. Someone reminded me to put the link in the description. I always forget to put links in the description.
