The one righty tighty is using is for on the car use. Yellow Rose, your's looks handy for home made. I have a Lisle 16750 for on the car use. (set it once and it works for all) and a 44300 for on the bench. I always wanted one for rocker shafts but with those you have to remove the shafts anyway and use a dummy shaft or unload the original shaft.
