Ft Gordon for Signal AIT in 1973 for 9 months, then Permanent Party in 1984 for 2 years, and last time was Advanced NCO course in 1989 for 18 weeks. My Advanced course class rooms were in Brems Barracks. They moved the MP course back in the late 80's.

Dave,
Thanks for your service as well as your support! I'm supposed to be dropping the butter bar by the end of June. So I'll be halfway past all of the LT jokes.
Since I'm in charge of wheeled vehicle mechanics and armorers, I enjoy getting my hands dirty and getting to know the Platoon. Many have told me that I've earned their respect, due to the fact that I actually understand the work that they do and some of the struggles they face.
1983JZR3W,
It's definitely a small world between us service men and women. I am constantly running into others that I have met somewhere along my military career. As short as it is.
Isaiah

Onto some more updates. There's a couple big ones this week. Pictures #60-62: Continued work on bracing of structural sections. It seems like progress with these extra bars takes forever. I tend to do one a night because I am tempted with getting the motorcycle out for a cruise. The weather in Ohio is finally where I like it. (BIG Update #1) Pictures #63 & #64: I got my hands on a 3' x 8' sheet of 16ga steel for a lump sum of $0. A favor that I will surely be returning.... as soon as I can figure out how to. Pictures #65-69: Since adding supporting structures seemed like it was taking forever, I decided to switch gears and finish the cage structure. The overall cockpit is pretty much complete. Just supporting structure is needed now. Pictures #70-72: Bearings for the steering shaft came in! So I began mocking up the mounts and am thinking I'll need one more bearing or support of sorts near the upper U-joint. I am getting a loose feeling from the play in the bearings. I'd like for the steering wheel to not be able to wiggle from side to side when my hands are on it. (BIG Update #2): My biggest update yet maybe? I finally have a donor motorcycle! It is a 2002 Yamaha FZ1. If you're not familiar with the model, it is essentially an R1 motor sitting in a sport touring frame. I am told by the previous owner that the motor has R1 cams installed. The FZ1 came from the factory with a cam suited for a flatter torque curve than the R1. If the cams really are installed, I essentially have an R1 powerplant in a steel frame. The only other aftermarket parts it has are a Two Brothers exhaust and different turn signals. There is one problem with it. The Carburetor boots are beginning to crack, but not to the point where they cause a vacuum leak. I will need to replace those sooner rather than later. I promptly registered it and have been enjoying the boost in power over my current bike, a 2006 Yamaha FZ6.   |

Been super busy at work lately, so I haven't had time to write up a good update. The past three weeks I've been out of town for various different reasons, but I was able to work on the trike at least a couple hours on the weekends. I'll keep it in chronological order the best I can. First Update: I've continued work on adding structural support bars throughout the frame. I've attached some photos. Nothing too crazy to look at here.    |

More Updates: Began Stripping down the donor bike to get it ready for fixture and mounting to my cockpit. I used some angle iron and castors to hold the front end up off the ground until I could get it in place behind the frame. I've attached more photos showing the bike and the "legs" I made.    |

The two frames are for the most part, one complete frame. If you look at the first picture you can see my method of attaching the long bars to the motorcycle frame. I bolted 3/16 plate into point of the frame that I felt were strong enough to act as "landing pads" for structural bars coming from the frame. There are four total and I was able to finish up the welding late last night. As you might already know, I have many other photos in my google drive showing different angles to everything I tend to upload to this folder first, then write posts in this forum when I get the chance. In case you don't see an update on here, you can always check the google drive folder to at least see what I've been working on.

Nice work so far, you might want to add structural gussets about the motorcycle front top mounting plate. Under the foward thrust that mount will be absorbing a lot of force, two gussets above the plate will help prevent flexing. Thanks for lots of pictures and details, good luck!

Nice work Lt. I understand the "Out of Town" issues. Retirement is so nice. Over engineering is my Forte!  I would rather put gussets on everything than have to spend weeks recovering in Hospital when it falls apart. And adding a 1/4" or 1/2" 0.062 inch tube in to triangulate a square area doe not add too much weight. |

Joe, Is this the area you are recommending gussets?  |

I have been thinking about adding more structural braces using smaller tubing, but haven't decided on where its needed. Any recommendations from forum members would be highly appreciated! |

Found some time this weekend to start the wiring harness!! Over 4 hours and 60+ solder joints to get to this point. I also mounted the light bars that I'll be using as headlights. They are a focused beam and super bright! All while pulling only half the power the original halogen bulbs used. See photos attached. Next step will be the controls.    |

I know you are still in the tack welding stage but YES in your above picture it does need some gusseting. Sort of like this (in Red) and weld up those joint cracks (in black).  |

Since the pictures above I have finished all of the welding. As far as the gusset recommendations go, I did have a plan for adding some on the lower portion. Hadn't thought about the upper portion until you two commented. I think I have a pretty good idea on how to tackle that. Updates will follow.... hopefully this week, being a holiday week, I can find some time to get good work done. |

I have been thinking about adding more structural braces using smaller tubing, but haven't decided on where its needed. Any recommendations from forum members would be highly appreciated! Ideally, anywhere the tubes form a 4-sided bay it should be triangulated by a diagonal. Otherwise the tubes and joints are subject to bending, which magnifies loads compared to only tension/compression when triangulated. |

On a few race cars we just used 1/2 inch EMT as bracing. It is a thinner wall and light weight and should never be used as the main structure frame but as cross bracing and to mount lights or dash parts it works well. Just remember to grind the galvanization off the weld areas and do not breath the welding fumes as it will make you sick.

Just remember to grind the galvanization off the weld areas and do not breath the welding fumes as it will make you sick. Yes, even cause brain damage. First dip the ends to be welded in muriatic acid and that will dissolve the zinc inside and out almost instantly. Do it outside, and hold your breath. Rinse with water as of course the acid itself is toxic and corrosive. Then you can move back inside for your welding, but use ventilation as you always should with any kind of metal welding. |

Thanks for all the tips! I think I'll stick with tubing that isn't galvanized though.... I'm ok with the extra cost if I avoid dealing with those health issues. I have gotten the clutch, throttle, brakes, and temporary shifter hooked up, but am going to need rethink my shifter setup. What I've currently got is a pull pull system using bicycle cables. This was more or less so I could get it out for a test ride before figuring out what exactly I want to do. Its not a good assembly and the cable housings cause all sorts of friction which stops my lever from returning to center. I've been out of town all week for work and haven't had time to write up a good post, but if you look in the build log you'll see that I've been working on things when I get the chance. I still need to review the structure and decide what areas should get structural bracing. For now, I believe I am ok for test drives around the block, except for the gussets around the head stock. Here is the link to the build log: drive.google.com/open?id=1oBlSssnbgsK_iEgZtF5DRVPc_4wc69sRcaptainamerica I looked through your build thread but I must've missed what size tubing you used for your sway bar. Any chance you would want to share your details with me? I apologize if I missed it. |

Update July 18: So I spent the weekend buttoning up a few things and racking up nearly 150 miles on the Trike. It felt good to finally get it out of the garage. Although I did end up stranded on the side of the road, and it was my birthday! I had an issue with the slave cylinder I used for the clutch. There's an end cap that acts as the mechanical limit for the piston inside. I forgot to give the threads on the end cap a little loctite and it eventually loosened enough for the piston seal to poke out past the end of its travel. It damaged the seal, but since the amount of pressure it sees is comparably low, I put it all back together properly and it works without issue! I went ahead and ordered a replacement just in case. Attached to this post, you'll see photos of the shifter cable I used. Its made by TCI automotive and usually used for automatic transmissions. It works flawlessly for my application and acts as an alternative to using a complicated linkage system. I would highly recommend it to anyone looking for a mostly flexible/rigid solution to routing shifter components. In my application it has two slight bends and operates with little to no friction. See the Mostly Finished Trike in the attachments as well as in the build log photos. Link Here: drive.google.com/open?id=1oBlSssnbgsK_iEgZtF5DRVPc_4wc69sREDIT: The "insert attachments" button is not showing up on my end today... You can see the photos and even a couple video clips of the trike in action at my google drive link! |

Isaiah, sorry but we had an issue where we hit the 200 Meg limit for attachments. It was allowing members to post up to a 1 meg picture and some builds have 40 or more pictures. So 5 members postings could lock us all down.
Everyone needs to find a photo hosting site.
