Just solder it

Well, crimping a stainless steel tube actually isn't very easy, as I had to learn. So a solder free solution isn't really in sight.

Furthermore I do not like the gap between the screws caused by the crimping, as it hinders the flow of molten plastics. Therefore I came up with a solution, where the barrel is soldered to the upper screw.

I think this solution is the best one as it leaves no gap open and allows me to change the barrel and/or the nozzle. In fact I only need two barrels (one for ABS and one for PLA).

So I've begun to make the barrel.

Next step will be the nozzle.
