A Bit INSTRUCTION:The tube itself under the flu consists of three parts on the thread. I recommend threaded parts to assemble on a threaded retainer (glue), otherwise there will be permanent untwisting. The cable is twisted into the handle for several turns and does not go further, it is necessary to drive the thread. Under the sleeve that presses the glass it is necessary to put washers, because. There is a gap to the base, and if you squeeze the glass will burst. In general, like all tuning parts requires attention to detail and refinement with a file.
