Today I took off the jointer guard of my Grizzly G0490X. I made a mistake by taking the bolt out of the top rather than the set screw from the bottom. The spring became loose and I'm totally confused on how to get this thing together with the spring tension as before. I've played with it for a couple hours and quite honestly feel pretty stupid. It's only a couple of parts and I just can't put it together with the spring tension as before. I get it back on but totally unable to adjust spring tension. HELP
