Jammed Steel Fish Tape / Rewinding Steel Fish Tape

After successful running wire through 3 conduits, my 125' steel fish tape got totally jammed, I don't know why. Wouldn't go forward, wouldn't go backward. I went to Youtube, no answers. So I unscrewed the 4 screws, and if I were to do that AGAIN, I would have FIRST prepared like 5 lengths of strong string/rope, and maybe a couple of bricks...because when I opened the casing, I WAS able to hold the tape down (to keep it from popping up & out), but then I had to leave to get scissors/rope, and I put a couple wrenches on it in the meantime to keep the tape down, but it ended up popping out....If i unscrewed the casement, removed one half of the casement carefully while laying bricks down, then tie pieces of rope, to keep the things down....I may have been able to figure out the situation, or at least, pull out all the tape, perhaps adjust something, and reel it back in. INSTEAD, the tape all popped out & tangled, BUT within an hour I was able to untangle, re-attach the one end to the inside of the reel, rescrew the thing back together (not shown on video, straightforward & easy) and wind it all back up (not shown on video, was super easy!). BEAUTIFUL! !! :D
