theres two... introduction and advanced.
Introduction is 11weeks and I presume working on random bits of metal to show you techniques and stuff.
Advanced is a bit longer I think and requires you to work on your own project.
But for the money, don't think you can do any better.
Theres a course at City College (Coventry) but that a 2 year full-time course. And nothing at either of the colleges in Nuneaton...
Hows the shoulder holdin up??
