Hello!
The timebase knob has been acting up lately causing it to skip steps when changing direction. I have been meaning to fix it for awhile but only recently aquired the right tool
to remove the knobs. Aaand additionally, it has finally failed completely.
Anyways, as expected it turned out to be a mechanical issue. The first (longer) plastic cylinder had broken off right after the cogwheel that makes the clicking indents. Fortunately it was easily glued, and as there is not much strain there I expect it to last quite some time.
Although this (the main timebase functionality) now works again, there was still some additional resistance when turning the knob. This came from the additional functionality part (the one that changes when pulling the knob and turning). After having a closer look at that part I found some broken pieces of plastic in there as well. I got them all out and as they seemed rather glueable as well, I attached them as I think they they were before breaking off. See the picture with the cylinder, spring and wingy plastic thingy. The wings of the plastic thingy fits into slots in the cylinder when pulled far enough.
Here is also (finally) my problem. When assembled and pulled the second cylinder now also turns as supposed to, however when not pulled it still is not pushed out far enough out of the slots to not turn the cylinder. By my estimation it needs another 1-2mm. The limiting factor is what protrudes from the pot but I cannot find anything that's adjustable enough to provide the extra space.
So I am looking for some input. Maybe someone has been there already and seen the mechanism and can tell me if I have assembled it correctly. Maybe I added some length when glueing it together, but I have a hard time believing that I added a mm. I could possibly also scrape some off the wings, but I'd rather not
I'll appreciate (almost) any input
