Guys, I have to tell you some things
1. Machine
shop always do its job perfectly. There are no differences between batches and all GG constructions are always exactly the same. When you see a difference is because I ask machine
shop to make it like this. Even the smallest change is made because I recheck the designs before the new batch and I make very small changes like 0,1mm where an o-ring sits etc. Of course I always check if the changes will work ok with previous batches.
2. Now, about Ody. When ana send me back the bases, I checked
threads and I saw that there was no problem with them. But I forgot to check the total length of the bases. Now after ruj post I checked the length and I saw that we have 0,5mm difference. That happened because I made the base of the base 0,5mm fatter to make channels under the base a little deeper. But I forgot that the pin of Ody wouldnt fit well that way. So yes, ana was right from the begining.
As I have said a lot of times in the past, I always try to leave room for bigger or smaller o-rings to avoid issues. So the simple solution is to put a thinner o-ring under the center pin. That means that if you remove the 3x2 o-ring and put a 3x1,5 o-ring , your problem is solved.
Ana, I am really sorry that I didnt manage to see the problem on your bases at once.
