That's very helpful! Appreciate the effort to draw it out!
My spring needs some adjustment then as it doesn't sit over the hole as you rightly said trying to get the Arbor hook engaged and get into its hole at the same time is what's causing my problem. I did think about manipulating the spring but didn't know if I would damage the MS.
I will have a go at centering it whilst I wait for a new Arbor and spring to arrive.
Thanks again for all the help, it's been invaluable!
Glissalube 20 is 8217 and used in automatic barrels. Others forms of this grease is used for aluminum and brass barrels. The fit should be tight. If the end is not in the correct position over the hole in the barrel it could still slip no matter if it’s tight or loose. It should be positioned to where the hole end of the should be in center of the barrel slightly offset. I would love to show a pic but I don’t have any movements apart on my bench currently so I drew a makeshift diagram. As you see sometimes a new MS wont line the end up with the barrel hole so adjustments should be made prior to the end to get it centered. You are trying to hook the arbor on then trying to move it over to set it into the barrel hole which iam going guess that’s why it flew across the room.
and I just realized I drew the MS backwards but you get the idea.
Thanks for this, I used breaking grease 8217 I think was the number, however looking at these videos I put too much on. I will address that.
I got the barrel apart last night but again ended up fighting with the Arbor before and hour before it went flying.. new one on order...
As for manipulation of the end, I've not done this before, the couple of manual springs I have changed for new the Arbor has just fitted straight in. This sounds like it might be part of my problem as the end of the spring just seems too tight to accept the Arbor.
