While installing a trolling motor mount to my kayak (Really? You're supposed to paddle them?) I realized that I could reach the head of the nut with a ratchet in my right hand and box wrench in my left, held under the deck, but my arm wasn't long enough to start the nut on the threads.
Step 1: Attempt #1
It should have worked. Unfortunately, I couldn't keep the washer balanced on the nut long enough to get it threaded. I tried taping the whole works together, but I kept either knocking the washer out of line with the nut or pushing the nut hard enough to make the tape come loose.
