Good evening,
I've been thinking a lot how to realize the bearing for the pivot and
have made the attached sketches (fortunately the STLs of the parts can
be downloaded). The quick release bolt (light-blue) is an M10 bolt [1]
and the rod-end bearing (red) is a bearing with 10 mm diameter hole [2].
The idea is that the rod-end bearing would be connected to the rear
frame and the green part is part of the front frame with a M10 thread
inside (or a M10 nut on the other side). The construction would be
mirrored like 10 cm lower so that two bearings are forming the pivot,
just like in the design by Dirk [3]. In the sketch the quick release
bolt is not fully fastened to show where the bolt is actually located.
What do you think, would this pivot work?
Best wishes and have a nice weekend,
Matthias
