About a week ago, I discovered that the mount part of my 135mm f/3.5 Weltblick lens did come loose.
You can only tighten that by removing the focusing barrel. The focussing barel (part B in the image below) is attached to the lens by a heliod coil (part A in the image below) that at the same time functions as an attachment to the mount part (part C in the image below).
I've been fiddling around for more than a week now, but cannot make a working union.
I start by attaching A and B (because this gives me a reference point for infinity focus). Next I try to attach the combi to part C, but it never works: focussing the lens unscrews to a certain extend the coil (part A).
Could one of you please help me, because I really want to make photo's with my Weltblick.

Ok I am stating the obvious...patience is the key here I lost mine and broke the lens when I was oh so close to getting it back together.I have a soligor 200mm post some where in the repair section I think it was B to C only turn one and a half turns then A to B+C one turning in one direction and the other going the other way.The one and a half turns is the key as it draws both pieces together with the bit left over for focusing room.
I wish my memory was better but I am sure someone will add to this help.
This is my post about the soligor

That I found was the hard part to get the scale right but I don't think impossible if you are willing to fiddle with it a bit more and mark what works and what does not.I broke mine so can not do the last adjustment but I learnt a lot and understand how this certain lens works.
Good news that you have it back together.
