I'm an Engineering Student in Adelaide completing my final year project and I need to mill out a slot in 1m long stainless steel 1/2'' SHS sections to lighten them for use in the rotor arms of a wind turbine.
We need this done ASAP as our seminar presentations are in the last weeks of September. We have existing aluminium rotors however a 2month delay in our actuators which sit on the end of our rotors has meant we have had to compromise and use big heavy brushed DC motors and planetary gearheads instead of nice light brushless motors with worm gearboxes. This has required a massive redesign to stiffen the rotor arms and basically we need stainless to take the load. But its too damn heavy! We need to slot the side walls... but they are a metre long, anyone have a 1m long mill that could do the job... noting we are students and looking for serious generosity!
Thanks for your time
