My old blacksmithing group at Forest Gate Learning Zone Monday 19th September
This activity used to be run as part of the Adult Education setup by the London Borough of Newham.
It is now run as a club £180 per term for 10 weeks for three hours. Materials and consumables included (within reason).
I am of the opinion that the shorter one or two day courses do not give you any real skill, this takes time which is why I would favour a longer 10 week course. Not so good if your not local - but one of the gentleman on my course for a couple of terms lived in Oxford. You can always visit them before you commit - Monday Afternoons and evenings.
