I didn't want to necro post to this original thread:
But I wanted to add to it. I just finished up a stainless backplate. I told myself I'd never do another one, because they're just too time consuming to make as a one-off project. But I had a piece of 1/8" plate, so I figured I'd make another and follow the suggestion given by "airsix" in the last post of the linked thread.
THIS is my last one! I really don't know why I bother since I have 3 DSS plates that I prefer. But not everything I do makes sense.
