Welding together the big frame for the injection molding machine was the easy part. Now comes all the small stuff that takes up all the time, but makes all the difference. Todays mission is to make holders for the temperature sensors which will give a good connection against the circular cylinder where all the melted plastic goes. It's the aluminium block you see in the lower right...

Also the brass end plug needs to be transformed into a makeshift nozzle, which is why Im taking a trip later this week to my metal shop out in the woods. The nozzles need to be machined nicely and get a hole drilled through the middle in a perfectly sized diameter (that I have no clue about). I think I'll start with 3mm.
