Update: 9/25/2010 to http://openpcr.org/2010/07/treat-your-machine-shop-professionally/ Good comment from mo - spread the love around. I want to point out that the relationship with your machine/PCB/acrylic/wood shop can be challenging! It's important but not necessarily easy! If you can't meet in person it's tougher to build repertoire over email or telephone, no matter how charismatic you are. And though I'm usually close to my email, people in shops are on tools and machines most of the time. A phone call is a lot quicker and more personal, but conversations on the phone often lead to miscommunications...



Machining aluminum

Another week zooms by! I've been working on sourcing for the aluminum heating block. One thing that's a bit elusive is finding shops to prototype the block out of 1100 aluminum. Most prototype shops stick to 6061, which is a strong material, but we want as high conductivity and low specific heat as we can (reasonably) get, and 1100 is the purest alloy of aluminum. The material itself is cheap but because it's a softer (I think) grade of aluminum, it takes more time to machine. CNC machine time adds up very quickly so Josh and I are both putting out requests for quotes to different shops. Chime...
