I made a spoon out of a cheap stainless teaspoon once as a gag if that counts. Actually caught a northern or two, but that's a northern. These days it's mostly the usual live bait walleye rigs with little modifications that I like to think work better (but likely don't ). Always better if caught on something you've made!

My brother builds almost all the spinners I used for UL trout fishing. I keep a few store bought spinners around, but not many. I do use store bought for where there is a single hook restriction such as on TN and NC native trout streams and streams in Smoky Mountains National Park.
