Yes I use one of the same design that I fabricated myself when I was young and dumb or was it when I had more time than sense. It has served me well and I am pleased with the performance. It is worth mentioning that it is imperative that the wrench is fully inserted into the front ring or the action can be tweaked pretty easily

Myself and many others have learned this lesson the hard way. I was fortunate that my experience only cost an action wrench, others learn this at the cost of an action...
