The advice from these people should not be understated.
use a proper Jig for every step of the process, accuracy is important or it won't fit together properly.
do it by hand by guessing.
use a Chop Saw to cut each piece, be sure you take into consideration how wide your blade is, they aren't all the same! They are also very fast!!
use a hand held tool, it's slow.
use an appropriate press with an appropriate stand. 10 ton should be able to crush smaller EMT.
use any hand held tools. Your ends won't be flat or parallel, both are important for the overall stability of your structure.
use a vertical mill/drill press. By following these simple instructions each of my struts are accurate to +- 1/100 inch. I also finished the whole project by my self in 3 days. I used a Bridgeport like this one to do the drilling:
My Bridgeport is serous overkill but its sure fast!
If you buy all the "basic" equipment to do it right you would have to spend about $800. Use what you have at hand or borrow from a friend. I'm sure you are no more than a phone call away from all the equipment you need. Good luck and remember, measure twice, cut once
! If you calculate it properly you should end up with no more than a few inches of wasted pipe when you are all done.
