try useing a small washer at the longer post , when you wrap your coil wire around it ,slide it between the washer and sleeve, so that when turning the screwhead to tighten the coil in place, the coil shouldnt pull the mesh to the post.
also , when i put the rope through hole to tank,i made two loops and wraped the coil around it about four times, first, making sure that the peices of rope was long enough so i can wrap the coil and have plenty of stringer to thread it into tank,then i attached coil to srew pins and put some drops of eliguid on it . then i wrapped 3/4" of the rope ends with some mesh , squeeeeezed and rolled it really tight then slid through the hole pulling it through til the slack was all out and i screwed on the atty cover, then i cut the rope , the length of the tank, filled tank , put rest of it together then vaped.
