 Two days ago I went to town to try to buy a steel pipe long enough to be my propeller shaft But they only had one that was thinner wall Basically no good. It was too weak So I got back here, and I'm gonna figure out what to do to connect enough of these things together to make the propeller shaft I'm worried about that next But yesterday what I did was I mounted the gear on here now this is this has always been one of the The trickiest things about building things with gears is getting the gear to stick to the axle Because a lot of times, you know if the gear is driving the axle it's kind of hard to get it to attack without slipping So what I did here is this is a bolt And it goes in about this far And I cut the bolt head so it makes this star shape And then I carved out the star shape in the gear Then I heated up the bolt and stuffed it in there so it melted itself right into the gear and then Since that wasn't gonna satisfy me I did basically the same thing with the other end. I took this pipe Cut it six times flared those bits out and Then carved the corresponding grooves into the gear then heated this up and stuck it in there to melt it in nice and solid So now that gear is Is stuck on there on the bolt going through of course is held in with another bolt going through this way This thing is like gonna break before it slips Not that I want either to happen This is non adjustable which may become a problem at some point And which time I will make it adjustable pretty sure I can make that fit that'll be my splice between my top pipe and the bottom pipe Now I had enough length That I won't need a third whole piece I try to go any further that it's gonna break there should still be able to get all the way through Even though I don't have full threads Since this is gonna have a joint in the middle I'm gonna put a ball bearing well a roller blip roller bearing here Be a good idea even if this was a solid piece I Did just make one and it'll use The actual shaft as the outside So I just need to get this part on there. I'll leave the nub sticking out of these ones These bolts in cases bearing tries to escape straight enough Guess I better put this in place before I bend it I got them all in there. Hey to plenty sticking out at the bottom to attach the propeller. I Think I have some ideas of how to get a bearing in here Without having to take the whole thing back out a little too tight in there the bearing down in the middle I guess that section of pipe is a little skinnier than the rest I can pull all the little rollers out and shave them down a tiny bit Hold on I just pulled it out and there's a bunch of dirt in there Maybe I just need to clean the tube That should be right about where the bearing is. I had some poorly timed rain Another 20 minutes and I would have had this bottom part reconnected and water wouldn't be able to get in there So I'll just have to cover it right now until it blows over
