Just something to think about....it would really cut down on the load on your motor.....

This is true...I really like the 1515 due to easiness of mounting stuff with t-nuts, but you are right, using normal alumimum would take down the weight significantly. In fact I think we have some square tube just lying around in the storage room as well....looks like I'll have to start drilling mounting holes again...
