Tools
When hot, the surface of aluminum mars easily. To eliminate scaring, with your tongs, hold the
material by squeezing it edge-to-edge, not faceto-backside. Next, cut yourself some hardwood
blocks to sink the hot aluminum into (see photo).
Steel forming tools will probably still be a part
of your forming process, but the wood tools will
greatly minimize your clean-up/finishing time
Aluminum is easy to forge, but does require
attentiveness. I cannot write with firsthand
knowledge about how oceanside balcony
railings subjected to salt water spray corrode. What I can write about is how aluminum
stands up in climates similar to Minnesota. If
you forge exterior ornamental aluminum in a
climate similar to Minnesota's, then:
1. Design it with strength in mind. If your artwork is structurally weak, add a background
and discretely weld the elements to the
background, strengthening them.

Bottom tools.

2. Consider using alloy 3003 for sheet work.
Alloy 3003 is recommended for marine
applications and workability. I do not have
experience with 3003, but I am shifting
from 6061 sheet to 3003 with optimism.
3. Pay extra attention to your fastening
locations.
A. Design simple expansion/contraction
slip-joints in between stone or brick
columns. In between stone or brick columns, slip joints should be used with
steel as well.
B. Bolt railing feet in place. Important
with expanding anchors or epoxy
when anchoring studs is with compressed air and a stiff barrel brush,
cleaning out the holes after drilling. Be
careful when blowing compressed air
into a drilled hole, as grinding dust will
shoot back at you. All anchoring methods are compromised when working

against a layer of drilling dust (miniature ball bearings).
C. Place a barrier (rubber sheet) in
between aluminum feet and cement.
D. Use stainless steel fasteners to retard
galvanic corrosion. When applying
stainless nuts on stainless studs, apply
some Never-Seize or an equivalent.
Seized stainless nuts during installations are not common, but they are
really a drag when they do happen.
E. I avoid boring holes in cement, painting
a rubber coating around aluminum legs,
and then casting them in the concrete.
The expansion and contraction of steel
is very similar to concrete. Aluminum
expands and contracts much more than
steel. The concern casting aluminum
in- place is the extra expansion and
contraction, loosening the aluminum
in the casting material.
4. Prep and paint your aluminum well.
5. Here comes the trophy. Revisit your project in 15 years, and if your paint is doing
its job, find decorative metalwork that
looks like it was installed last week. This
is good.
In closing, I want to thank NOMMA member Jack Klahm for his pioneering with aluminum. It was after watching Jack demonstrate
aluminum forging many years ago, that I
thought I would give it a try. I'm glad I did.
Thank you, Jack.
As always with the Collective Mind
series, if you would me to add or have a
different approach to something, email
your thoughts to NOMMA editor Marbella
Miller (marbella@naylor.com), and let's all
become more knowledgeable.
Good luck!
Uncle Bob
