How do you raise up the gantry? Do you need to do one side, then the other? So they are offset when you lift one side, then walk around to the other side and raise it up to match? Or does it require 2 people at the same time?
I would be pretty shocked if Northern tool asked for that back cuz you actually paid for one and they made the mistake....and by featuring their product you actually gave them free advertising on youtube that probably will make them plenty of money to cover the difference. They give out free stuff to folks to feature on here all the time...yours would be half paid for.
