I meant to update part 2 forever ago…but here it is now!
Last time I finished rambling about the deck and the fork. After that I started working on the folding and locking mechanism:
First I wanted to give the base of the handlebars more material so that I could make a fairly beefy pivot joint for the folding mechanism. I could have found a big block, drilled a hole in it the diameter of the handlebar, and then glued it in. But I didn’t have a big block, so instead I chose to glue lots of smaller bits to the base to build into a block. In order to have flat surfaces to attach small blocks to, I started by cutting the base of the handle at an angle.
Next I wanted to make a mechanism that would securely clamp this pivot to the front fork. I really wanted to use a bike quick-release mechanism, but I didn’t have the right tap, and couldn’t think of an easy way to do it. So this is what I came up with:
First, a bracket that goes on the front of the fork:
This bracket receives two threaded rods that go through the front fork. On the other side there is a latch that clamps to the back of the handle bar pivot.
yes, these pictures are taken in a bathroom.
About this time I took it all apart and applied two coats of polyurethane. I used spray on, high gloss, which resulted in kind of an orange peel texture. But the bark isn’t smooth anyway, and its something that I will step on with shoes, so its probably better to not have a perfect gloss surface.
Finally, I made a latch to keep the scooter folded. It makes it much easier to carry around.
Soon I’ll post a video of my neighbor riding it (because I have no balance, and he does…).
