| Writer: clarnibass From what side of the cork is information technology broken? It's not articulate if it'southward just a piece missing at the cease, after the cork, or the entire tenon including the cork. Can y'all post a photograph? If it's the entire tenon, epoxy might exist strong enough, simply might not exist. It's risky. The type of epoxy is also important, you need a stronger slow setting one and even that might not be potent enough for this purpose. If it's but the end of the tenon so very strong deadening setting epoxy will probably exist ok fifty-fifty without reinforcement pins simply information technology's still a small risk. My preferred method for gluing broken tenons (prefer to grafting) is to gum with potent epoxy and reinforcement of stainless steel pins that are parallel to the diameter like yous described. However, the disquisitional thing about doing this is that the pins demand to take air vents from the blind end of the hole. The pins need to have complete support of glue inside the holes, with no air. Without air vents you will get air bubbles within the holes (so bad support) or you won't be able to insert the pins (considering of air pressure forcing them out). I utilize a 0.5mm drill for the air vents and they are almost invisible because they are and so small. They are just small-scale holes drill from the blind finish of the pin holes from the side of the body (just to the hole, non deeper). I then force the epoxy into the pin holes from a syringe, slightly rough and smear glue on the pins and put them in the holes. For the tenon terminate of the holes, you lot might not demand air vents since you will have "automatic" ones by the area of the tenon band. Another selection is a solvent glue like this which was recommended by a couple of repairers http://www.oatey.com/Channel/Shared/ProductGroupDetail/ane/All+Purpose+Cement.html I prefer the epoxy with pins, eventhough information technology takes longer (but usually not equally long equally a graft), considering it is most likely stronger than the original, which bankrupt. As long every bit you treat the clarinet unremarkably, almsot as strong as the original is probably stronger than information technology needs to be, but I rather not take a chance it and make it as strong as I tin can. |

| Author: jmsa Y'all tin besides put masking tape around the end of the tenon with the glutinous side on the inside and pour finely ground grenadilla powder ( Ferrees sells this) and so use very thin and runny Cyanoacrylate. Then later it dries but remove the record and sand to proper length. Works smashing on chips and missing pieces at the end of tenons. jmsa |

| Author: Ralph Katz Have you tried contacting the manufacturer? They might sell you a new, unfractured upper joint. jmsa: this is not a wood clarinet. |

| Author: Tony F When drilling the holes for the pins on a broken tenon, I've found that if you apply a syringe with a broad-bore needle, all the same small enough to go into the pigsty, y'all tin can inject the epoxy correct to the base of the hole. When the roughened pins are pushed into the pigsty the surplus will exist expelled. The hole is then completely filled, with no air gaps. This eliminates the need for air bleed holes and makes a slightly stronger repair. I commonly insert half-dozen pins. Never had one break all the same. I use Monel metallic nails cut slightly shorter than the depth of the hole with the heads clipped off. Tony F. |

| Writer: BartHx I take successfully repaired the middle tenon on a resin clarinet using your option two. However, it is critical that the wire yous use and the holes yous drill be carefully matched. Resin is brittle and drilled holes practice not leave you very thick walls on your holes. I used wires mainly to resist twisting forces at the fracture line. If y'all were to use a standard replacement tenon, it would also work fine since it would be completely subconscious when the musical instrument is assembled. |

| Author: clarnibass For pinning, I have tried the method described above, no vent holes and using a smalerl neelde to offset filling the glue from the end of the hole. At that place are two reasons I prefer not to practise this. Get-go, my friend who taught me this method saw a failed repair when no vent holes were drilled. Second, when I've tried this, I decided it is non proficient enough to guarantee that the hole is completely filled. It might have air bubbles and there is no existent way to know if there are any. I've checked this by using a very small transparent tube, aforementioned diameter every bit the pin holes. Sometimes there were air bubbles, sometimes there weren't. I disagree that this is slighty stronger, or rather, that this is significant. The air vent holes are filled with the epoxy and IMO are insignificant to the forcefulness of the repair. Yet the guarantee that the entire hole is filled with glue with no bubbling is very important to me. |

| Writer: Tony F Hi. I quite appreciate your reasons for using your method. Something I didn't mention was that when I pivot a tenon, I showtime warm the tenon gently with a hair drier and as well warm the epoxy by floating it in a plastic cup in hot water. This considerably reduces the viscosity of the epoxy and also speeds the setting. By half-filling the warmed hole with warmed epoxy and so slowly inserting an epoxy-wiped pin I tin can exist pretty certain there are no voids. I generally us Araldite full-force for this. I stress that this is my method and seems to work for me. Your mileage may vary.☺ Tony F. |

| Writer: clarnibass Yep, I agree that almost probable there wouldn't exist air gaps... but I simply prefer the other method to exist sure. I besides warm the epoxy to make it thinner viscosity and I've used a few types, the strongest Araldite being i of my favorites. |
