Preliminary images of the end cap. I was inspired from the hydraulic quick connections such as "Serto" that using a tapered ring with a sharp edge to crimp the ribbon leather. Inside I used a plastic cap with a threaded metal core to screw the cap outside. Probably I will have to revise the form of a nylon plug to ensure that under the action of the tool does not slip inside the tube. Thanks to Tobias Mattsson for ready to employ logo! Rev: 3-2-12 After the prior images I upload now improved version of the plug and ring CONCEPT The concept with whom I developed this plug and the locking ring for handlebar is analogous to the hydraulic joints of rapid connection that contain a conical ferrules tightened by a screw. I assumed the dimensions in my opinion, but the final size of the ferrule and rings is dependent on the type of leather, by how thick and soft so that the sharp edge of the ferrule can hold it in place. The other element determinant of the assembly is the cap to be inserted inside the tube; It must be easily insertable and not rotate due to the action of tightening of the screw. In the attached photo you can see a plug for sparkling wine, really used for wine quality not excellent, casually sizes are nearly equal to those of the tube. So we all know that the grip of these plugs can be very effective and that if it were not for the action of the gases of wine would be difficult to remove, or at least it should easily withstand the action of the screw cap. Consider then that the roughness of the pipe is superior to that of the glass of the bottle and also I added one ring more than in cap. If you want to remove the cap, just insert a M8 screw and pull For information the wine plugs are for sale on e-Bay for 2 Euro per 100 pieces MATERIALS Cap and locking ring in aluminum, Ferrules in AISI 304 / AISI 431, Screws in AISI 304, Heart of the threaded plug, electrolytically galvanized carbon steel, Plastic plug in Polyethylene Logo: Aluminum sticker The paintings of colored bands should be made ​​"saving", With a CNC center run grooves on aluminium rod, painted the whole thing and then finish the piece by removing the excess material ASSEMBLY Insert the plastic plug in the tube, then they must be mounted the inner ring and the ferrules, Wrap the ribbon of skin on the tube with spiral left, stapling the tape with the ferrules, so that when is screwed the cap which obviously has right hand thread, the tape continues to tighten on the pipe. Place the ferrule on the inner end of the ribbon and secure with ring having three radial screws 120 ° . Alignment of the logo. Mounting with screw can submit the logo not in correct position, but given that the cap has a key of 30 mm, will be easy to take him in position Place the ferrule on the inner end of the ribbon and secure with three screws fixing the ring to 120 ° radial
