Some engineering recipes missing

[Bluerabbit]

I was looking to make Adamantite Grenades but can't find it in the list of things I can craft. I looked through the engineering trainer and it's not there, and it isn't sold by the npc on the isle either. I was only able to find an npc that sells the grenades themselves, but only 3 at a time. I also can't find the gnome/goblin transporters recipes.

Am I just blind/not looking hard enough, or are these not available to learn on this server?
