Blacksmithing in the San Francisco Bay Area

For the last 5 weeks, ending yesterday, Cristin and I have been making a once-a-week journey to Oakland to take a introductory blacksmithing class at the Crucible. The Crucible ( is a non-profit in Oakland which serves as a avenue for the industrial arts in the community. They tend to focus on alot of arts related to fire, hence the name.

The class teaches you several basic blacksmithing techniques as you create 4 projects over 5 weeks. You create a hook, which is looks like an enormous fishing hook, but designed to hang on a wall. You create a knife, or a shiv out of rebar. You create a spoon - the two week project. Finally you create a 2-pronged fork. And most people create two of each - one piece heating up in the forge while the other piece is being worked on. Here is a photo of some of the steps in the various projects:

There are a few other photos up on picasaweb of Cristin and I here: Blacksmithing Photos, but the most important photo is the one that resolves the "pics or it didn't happen" issue:
Cristin and I had a blast, so a small plug for these classes. Turns out that in a few weeks, they are running a special weekend "sampler": . They have morning and afternoon single session classes on both Saturday, Sep 19 and Sunday, Sep 20. It isn't cheap, but it isn't horrible either, $85/class. If you take two on the same day, you get $15 off the set. Cristin and I going to head up there on Saturday, Sep 19 for the whole day and if anyone else is interested in going, let me know.

The classes offered as samplers include:

  • Blacksmithing: undamental skills needed to forge steel and understand blacksmithing tools. Each students will walk away with a small finished project.
  • Glass Fusing: glass/heat interaction, glass cutting, fusing (combining colors), slumping (shaping glass into or over molds to create flat and dimensional forms), as well as a brief description of firing and annealing procedures.
  • Glass Flameworking: fundamentals of flameworking, and will cover a small variety of techniques like color pulling and applying, frit application, and marble making.
  • MIG Welding: Metal inert gas (MIG) welding, also known as wire-feed welding, falls between arc welding and TIG in the welding spectrum. Quieter and cleaner (and some say easier) than arc welding, MIG welding is typically used in production fabrication such as furniture making, light construction, and auto restoration. In this workshop you’ll learn the basics of MIG welding and plasma cutting.
  • Ceramics: no description online, but I think this is sculpting.
  • Jewelry: sawing, filing, sanding, soldering, texturing, annealing, stamping, polishing, safety, and design. Each student will walk away with one finished piece.
  • Sand Casting: Working with resin-bonded sand, you’ll learn the foundry basics as you build your own molds. As part of a casting team, you’ll have the exhilarating experience of pouring molten aluminum.
  • Resin Casting: Learn the secrets of plastic casting using flexible molds, just like the ones that professionals use for product development. You'll learn to make molds of found objects and use them to create plastic reproductions. Each student will walk away with one piece.

Duplicate Content & Multiple Site Issues

Earlier this morning I gave a talk at SES San Jose on Duplicate Content and Multiple Site Issues. For those who couldn't make it to the conference or just want a copy of the slides I'm embedding them here:

Keep an eye on the Google Webmaster Youtube Channel. I going to try to see if I can record the presentation and have it up there as well for anyone who missed it.

Update (09/17/2009):

The re-recorded video is now up:

As well as a interview with Mike McDonald of WebProNews:
