- This video shows build techniques for a swingarm of the OpenEmoto project. In this case the swingarm is for a hub motor, but there are other compatible swingarms to chose.

that jig setup using a 1:1 print and bolting 3d printed fixtures in place including height stand off's is awesome. that whole concept of jigging just burned into my brain
If this guy had all the tools and equipment I have in my shop he could probably build a space shuttle. Very good work with very little equipment.
I don't know what is more amazing, the quality of work you do with very little in the way of tools, the quality of your work, the prep work and lay out or the jig you built to hold it all. Great work.!
I Love that cutting grinder attachment . Sweet mod!
Thanks!, although it isn't a DIY version. It is something I brought as a novelty, not very useful. I use it only when cutting small tubings and don't want to reach the full size abrasive saw. Thanks for you support!
Great video... Great technique... Subscribed.
Good job..what a quality work👍👍
Very nice!
This is some nice work, I love the green mounts you made
Awesome video bro👍
Bad Ass. Nice Work !!
good job 👌
Just subscribed dude for your efforts
Is there any video on making headTube
Thank you! Have you checked out my video on making the Frame? czcams.com/video/nFmHWTzSU_E/video.html
About headtubes, I pay to a machinist to make it with a lathe. Here is the drawing I handle to machinist: github.com/eroldan/OpenEMoto/blob/master/MainFrame/HeadtTube.dwg
The above headtube holds a "44mm semi integrated headset" like this www.amazon.com/External-Bearing-Aluminum-Straight-Accessories/dp/B07G6X6NRV
Good luck with your builds!
What's the size of the tube you used for the pivot? Also, what part number bearings did you use to fit in there? Great video and great work too!
Thanks!. The pivot tube is 1 1/2 inch with a 2mm wall. The bearings are 10x30x9mm. Those are fitted with a cup (later welded to the tube). This cup is made with a lathe and the measurements are here github.com/eroldan/OpenEMoto/blob/master/Swingarm/PivotCup.dwg
@@OpenEmoto Thank you!
Nice 👍🏾
Que medida de tuberia rectagunlar usas?
I’m looking for a custom ebike swingarm and/or frame. Can you help?
Hi bro, what kind of steel did u use..thank you
Mild steel 2mm wall tubing.
Sorry I'm very late with this. Why did you weld the bearings in? How will you change them if they get damaged? They can't go anywhere held by the frame on the outside and the spacer tube on the other. Quite apart from heat damage to the bearing itself.
Good question. I think I failed to depict the process good enough. If you look carefully, the bearing is pressed in a metal cup made by a machinist. The weld is done between the tube and the cup. If the heat transfer of the tube/cup damaged the bearing, you can take it out and replace it. In this case, we can call this bearing a "sacrifice" one. I usually weld with high amperage and very quick, waiting to cool down between each point, so the bearing is not damaged, or not enough damaged for this function (not high rpm, not even a full rotation). Here is the drawing of the cup that is welded to the tube. github.com/eroldan/OpenEMoto/blob/master/Swingarm/PivotCup.dwg
@@OpenEmoto Ah it looked like you were welding the bearing straight into the swing arm. As you're using a bush then that Makes sense.
why you weld the bearings? is it the only way?
Jake Gyllenhaal is that you?
