    Building headstock, yokes, etc from scratch

    Yeah. I'm thinking I could hide the clamp within the design of the yoke. I was originally thinking of steel for yokes but am going to have to make them out of aluminium due to thickness and weight. 10mm thick steel yokes will weigh a tonne Sent from my CLT-L09 using Tapatalk

    Haha diablo. My bad dude lol. I did first think about rotated but then that would make tube fitting harder so may as well use round and mitre. My thoughts behind this build were... I had unlimited box at work to use for free (this has now changed but still like the idea) I wasn't hugely...

    Yeah the square shape is limiting for sure. The picture below was my initial idea. But that's not going to suitably clamp square legs. Or is it. The clamping force would only be on two side right? The benefit of your initial idea is I can use the same design across three potential...

    OK so both top and bottom are welded to forks. I was thinking maybe a solid 30mm aluminium rod going all the way through with tapped hole bottom and top and something like M12 screw both sides Sent from my CLT-L09 using Tapatalk

    Hey guys. I'm making a chopper style ebike. I've got my initial design I'm just struggling with some of the more specific details. I plan on having a square headtubeout of 60mm2 box. 5mm thick wall. I'll then machine out a 55mm dia round recess to sit the taper bearings in. I'm not sure on...

    That's an M16 countersunk. Actually... That's it sat in the bearing.
