Re: Construction materials

Aluminum box tubing (square and recangular) has been the material of choice for 696 since 2004. Previously we had used Bosch 30x30 extrusion but then we realized that it was too heavy especially with all the corner brackets and fasteners.

I'd say if your base frame is more than 15lbs and it's not a crab drive, you need to rethink it.

mechanicalbrain, what exactly did you have bend and what were the circumstances under which it bent? Any pictures?
