Is filling a crack with glue really gonna prevent the crack from spreading? I have 2 cracks on my lower tenon of the second part of the clarinet. I've thought about getting metal caps over them. Are Metal caps safe?

You can glue tenon cracks with no problem, provided the crack is cleaned up well, ie. there's no grease in it which will prevent the glue adhering to the wood.
Metal tenon rings will keep the tenons tight, and are 'safe'.
Make sure they're made and fitted well - this will mean turning down (and shortening) the lower tenon ring and having a nickel silver tenon cap turned and fitted, and the outside turned down so it will fit into the bell tenon.

Hello
This goes if you don´t want to flush a band around the instrument. If you´ll however do so, supposedly this will go as well.
Before cleaning & glueing, cut a (approx.) 45 degree "ditch" exaxtly in the crack with a razor or similar sharp tool. This will get the glue to make a stronger seal with a bigger contact area. I use super glue (cyano acrylat). If the glued "ditch" where the crack was, comes to be too deep fill it up with african blackwood grains and put on more super glue.
Afterwards, scrape the glue off with a very sharp knife. Scrape it until the hard glue/wood is level to the instruments wooden surface. The mended crack is not supposed to be able to see. :-)
regards
