Was just wondering if the break happened while thrashing and a wad came through when tightening the concaves ? Would put a greater load on the casting .

That is a very good question. Iím lead to believe that when running ACS, the system will try to maintain that setting.
It would make sense in what youíre saying but I have no confirmation this is correct.
It may just be that the lumps going through will eventually break something ...... & this is the first weakest point.

Correct, the speed of adjusting is so slow compared to the millisecond loading that occurs in threshing.
The only way it won’t ever break is open the concave wide open and if the concave sits on other stops the adjusting mechanism won’t break.
Doesn’t strike me as the complete answer.

Thumbs up V1.0 Flagship concave suspension

Here's the first version of the concave suspension kit I've been working on. Hopefully it will take the shocks out of the linkage ....... that ultimately end up in the little concave adjusting motor!
It will need at least a full season of field testing to see if they do the job.

Interesting.
How did you pick spring strength?
Any way to mount a camera for field observation Rod?
I suspect it moves both more and much faster than the bar demo.

Found the toughest spring for that length & diameter. Whether it is strong enough, I don't know.
Probably could mount a Go-Pro in there but I'm guessing it will look like an Alberta spring day ....... without the cold!
How much it could possibly mover up & down & how fast ...... is all up in the air. I'm not sure if this is the answer but its worth a crack at something.
adsinaus and SWMan like this.

Good luck with your project, keep us apprised please.
