Fixing a broken tenon on an old Vito Reso-Tone alto clarinet. What is the best cement to use- I have acrylic, ABS and PVC cements available, but need to choose the proper type.
Thanks,
Jerry

Araldite or any similar epoxy resin are best used for tenon repairs, but as it's made from resin, ABS may be the best one.
Are you fitting a new tenon or glueing the existing broken one back on? If you're glueing a snapped off tenon back, then you'll need to pin it to reinforce it as it won't hold with just glue alone.

To glue a broken tenon, similar to what Chris wrote, I use the strongest slow epoxy and reinforcement stainless steel pins. With this method, it is super important to have vent holes for the pin holes. I don't trust glue alone, regardless of what type of glue.
However, one repairer claims he gets excellent results by using a solvent glue. It supposedly "welds" the parts back together. In reality it doesn't really do that but since it is a solvent glue it does connect it in a way different from "normal" glues like epoxy, etc.
I think the glue is this one http://www.oatey.com/Channel/Shared/ProductGroupDetail/1/All+Purpose+Cement.html
This company also makes glues specific to certain materials that might work even better but with clarinets you never really know the exact material so this works best according to the two people who experimented with it.
I still don't trust it and prefer epoxy and pins, but it's worth a try maybe.

Actually, what broke was the reciever on the lower joint, not the tenon ( sorry to be imprecise). After reading all your posts, I settled on Oatey ABS cement and clamped it securely with a long screw-rod, large washers and nuts. Left it set overnight, then put the two joints together with the clamping ring that covers the joint. Tested it by applying plenty of bending force- it held well. Hopefully, no force greater than what I could apply will rise to challenge it; meanwhile, looks like we are back in business! Thanks for your inputs.
