Like Raul & Joe, I was actually cheering when I read about FIRST letting us use aluminum extrusions… thanks FIRST!
I’ve been using aluminum extrusions for designing machines at Delphi for the past seven years. So, for what it’s worth, here are my opinions & suggestions.
- What type should you use?
Like Joe said, there are these types with t-slots in them. These are what I suggest. There are four main companies who make the same type of extrusion:
…Item Products (all over US)
…Item MB (German, original maker, smaller US presence)
…ParFrame (Parker Hannifin, all over US)
…80/20 (metric type…all over midwest)
These four types are mostly interchangeable… but not completely. Item MB has the best selection, and they can distribute out of Dayton, OH. They all have lowered their prices considerably during the past 3 years… competition is getting fierce.
I would bet money that most distributors of these components would donate a decent amount of extrusions and simple fasteners to your FIRST team. Just tell them that they are dealing with prospective engineering students who know little about aluminum extrusions and let them give a 1/2 hour ‘speel’ on their extrusion product.
These extrusion companies have very good catologs that take a while to understand all that is available. Also, these catalogs will tell you how to use their extrusions, fasteners and joining plates.
Get yourself educated about these extrusions and use them. As you can see, we’ll use them, along with Wildstang and ChiefDelphi… so you better get some yourself. Beg and plead if you must… just use them.
Think about it… high strength, pre-fabbed, lightweight sticks with adjustable fasteners and neat-o bearing possiblilites with the t-slots… woof!
