I’m machining bearing guides that will weld into the top and bottom of the steering tube and house this shaft and bearings. Once the proper length of the shaft is determined, I’ll thread both ends. One end will thread into the bottom triple clamp. The other end will go through the top triple clamp for the nut that holds everything together.  |

…and the bearing seats are machined and ready to be pressed into the top and bottom of the steering tube and welded in place.  |

13.2lbs of aluminum will now be converted from this…  …to a pair of these….  |

So jealous of your cnc in your garage.

 A bucket and a half of chips later, we have this!  Mostly because of available stock, I ended up making the forks about 1/4” closer together. And because I had stock available front-to-back, I made the fork clamps a little bit farther out from the steering stem than they were. Hopefully, these changes plus getting rid of the extra rake will allow me to have the gas tank all the way forward, fork tubes not hit the tank, and still have a decent turning radius. It is proving to be quite a challenge to juggle all of these design features without finishing them. Had I made the seat pan when I got the framework in, I would have run the risk of needing to remake it due to tank position, due to fork position, etc…. Hopefully, I can keep it all straight. |

Guess that is why all the bike building shows always start at the neck and work from there. But impossible when you are starting with a already made frame and moving backwards almost

I will NOT look at what a CNC costs for my own projects.... I will NOT look at what a CNC costs for my own projects.... I will NOT look at what a CNC costs for my own projects....

 The hobby size machines are expensive, junk, or both. These big machines can be surprisingly “affordable”. They go “cheap” because the working shops want the latest and fastest available so when older machines come up on auction the big boys don’t want them and the hobby guy doesn’t have the space. My current machine, I paid the same to move it as I paid for the machine. All-in, machine, rigging, tooling, etc… you could get a machine like this for less than the cost of a side-by-side and when you are all set up, you could make your own side-by-side! |

Man, I didn't need to know that  Now I'm gonna have to go look. I get in enough trouble with the 3D printer, if I could '3D print' in metal I'd be making all SORTS of fun stuff. Things like your wheel fab project and this stem really has my brain churning. You're doing some VERY cool stuff. |

It looks more “bulky” to me than it did drawn up on the computer but I’m ok with how this is turning out.   |

Like how it turned out, should give you enough room to be able to keep your tank moved forward how you want it 🙂

The gas tank issue is resolved!!! Looks like I’ll have roughly 90 degrees of steering travel.  It’s amazing how much more smooth the quality bearings make this. |
