I am trying to remove my blades from my WB myself today (just got 3 sets of blades in) and I am having a little trouble. I normally don't do this myself, I have a friend with an air compressor and impact wrench that is powered by the compressor. Anyway, he is busy today and I think I should be able to do very routine maintenance like this myself! I tried to use this giant cressant wrench and it with no luck at all. It, of course, just wanted to turn the blades so I had one foot on the blade and the other foot on the wrench and still no luck. So, my question is... Do they make impact wrenches that are electric? I can't really afford to buy an air compressor, but if they have electric elcheapo versions that will get the blades off and on then that would suffice. Also, what are my other options? I don't care what tool is used, I just want a way to get the blades off and back on, I won't be using the wrench for anything else. Thanks for any ideas!
