    I went and bought a lathe for myself last fall. I've always wanted one.

    It's kept me pretty busy over the past winter. Here's what I have to show for the hack project:

    Turned this axle out (not yet cut to length)

    I bored out the center of the brake plate, and pressed a new center.

    Here's the axle assembled to the wheel.

    It's still early yet in the project. No guarantees on when she'll be on 3 wheels.

    I started assembly of the frame today. She don't look like much, but it's more forward momentum for the project.

    I'm hoping I can get the swing arm together sometime this week. We'll see.

    Well, life is full of surprises. This week, the exhaust fell off my '95 Miata. My girlfriend and I plan on taking it up to the mountains next week for her birthday. So my time will be invested in repairing that this week, instead of the sidecar project (boooo). On the upside, I scored a full exhaust for the miata off craigslist for $20 :rofl. Should have it back together by the weekend.

    Anywho, minor update: spent some minutes on the lathe.

    The piece on the left is the stock center stand / brake pedal mount. The piece on the right will be the new one that will protrude from the frame and serve as the lower rear sidecar mount.

    Finally, I've got something that looks like a swingarm! [​IMG]

    I wanted to step aside from the structural stuff for a moment, so I started getting creative with a pair of ct200 fenders I've had in my parts stash.

    Cut off the mangled fronts and spliced them together. Added a bit of support with a piece of bar stock bent around the edge.

    Well, I'm embarrassed about the shit welds (forgot to turn the gas on at first ). But here's the start of the lower rear mount.[​IMG][​IMG]

    I've been going hard on this thing - and loving every minute of it. I need to fab the upper supports and she'll be ready for a test run.[​IMG][​IMG]

    That sidecar suspension is pretty trick. Does it have enough travel? It looks like it would bottom out the shock pretty easily.

    Thanks! I've got to give credit where it's due, I 'borrowed' the design idea from this guy.
    I stood my 285lbs on the frame and bounced for a bit to try it out. I got to it budge a few inches and there's still plenty of travel left. The shock has a pre-load adjustment, along with the ability to add or remove air to change the dampening characteristics. I'll have to dial it in once I have the tub all built, but it seemed pretty close to where I want it :D

    Still some reinforcements to take care of, but she's a roller! Just need to setup the brakes before I can take her for a spin.[​IMG][​IMG]

    Proud to say, I took her for a spin yesterday! Plenty of ballast loaded up. My first time hacking. I'm going to need a lot more practice, lol.[​IMG]

    Excellent work! I'm still kicking myself for not pursuing the rough ct200 with factory sidecar that came up on Ebay in Nevada last year. I was high bidder and lost out to a last minute $380 bid! It was a sweet rig, but in really rough shape. I just didn't have time for that project at that moment. A nice Lifan 140cc swap would've made a very cool rig!

    That thing would have made a sweet project for sure! Though, I'm not sure Honda ever had a "factory" sidecar. Sounds like the seller was trying to bring the value up!

    Great build, I have a C110 sport 50 in pieces waiting for this kinda love.

    From what I understand Honda actually did have a "factory" sidecar, it was an accessory and appears to be a kinda universal design.

    Cheers! I really need to get mine put back together!

    I retract my skepticism, that's sweet! I'd love to see how honda mounted them.

    Ran across this interesting "ride along" side car that was made for the CT's:

    I spent a bit of time on the rig today. Mostly small stuff like adding gussets. I beefed up my subframe by adding a X section under the engine. I'll be able to start on the tub very soon![​IMG][​IMG][​IMG][​IMG]

    I got the floor welded in, and my 3rd brake hooked up. I practiced riding up and down the street for about an hour this evening. My face is plastered with a huge grin
    My father even volunteered to be the first passenger... for about 50 ft / until 2nd gear. Can't say I blame him, I haven't built the tub or installed any "oh shit" handles yet, haha.[​IMG][​IMG][​IMG]
