What do you regard as "wrought iron railings" ?
There's a wide range from bolting together components, to welding up
standard bar and tube stock, through to "artist smithing"
If you're interested in the artist end of things, then I suggest a
course. I was lucky enough to take a weekend course with Pter
Parkinson this year. I made this
He's also the author of one of the few good art-smithing books out
"The Artist Blacksmith: Design and Techniques"
Dona Z. Meilach also has a couple of good books out there
"Decorative and Sculptural Ironwork: Tools, Techniques, Inspiration"
and "The Contemporary Blacksmith"
You'll find ABANA or BABA the relevant associations for artist
blacksmiths and their magazines are good reading. There's also an
alt.crafts.blacksmithing usenet group.
What I am planning on doing is using some factory components with some
handformed and CNC plasma cut details. I would like to see some info on
planning and designing railing. I also need info on forming bends in
handrail caps although I have seen some techniques such as splitting the
handrail bending the two pieces separately and joining them back together. I
learned long ago that blazing a new path is a hard way to learn things
people learned long ago. Thanks for your help.
