that looks awesome! about the pivots: these are not bearings, that's just some kind of plastic i prepared on a lathe. i don't remember where i got the idea from, but if i recall correctly this is some plastic that can be used for purposes like this. maybe if you know somebody who knows about the different kinds of plastic they might help? or maybe somebody of the community here has more knowledge and is willing to share it?anyway - thanks a lot for sharing your build!

rotation was easy. of course it's probably not comparable to a ball bearing but there's so much force on these rod ends while steering that you don't recognize any resistance.

hi,sorry for the late reply. you mean the brackets to reinforce the pivot? yes, they are mounted in the order you described. this would be pics 3 + 4 in step 13, right?

thank you! there's a bearing cup at the bottom of the extended head tube, yes. probably it's a good idea to check if it fits in the new tube first before cutting/welding...

hi, that's 34mm outer diameter and 2mm wall thickness!

hi, hard to say from a distance. do you have a pic of your bike? there could be a few reasons for this... e.g. if the 90 degree-angle of the pivot is not really accurate the bike leans in turns (this is used with christiania bikes so that it feels more natural to ride the bike in turns). also if you turn too far the weight gets probably shifted to one side while the effective wheelbase gets smaller (think of the points where the wheels touch the ground: with a 90 degree turn they are all in line while the weight is on one side - this can't work :-) ). if you're riding too fast the weight wants to keep on track in turns while you try to move it somewhere else, this can pull your bike over, too, as i experienced in person a few times ;-)

:-) thanks!

yeah, i guess "beast" is the best description for it. a beast in the making, and to ride :-)thanks!c

..aaand another one did it :-) joel from sweden sent a link to a documentation of his bike: http://recycle-design.blogspot.se/2016/05/slutpro...check it out!
