Well, made it back from Alaska, what a nice place to spend some time. When I started this post, I had just used a piece of 20 gauge sheet metal just to see what was going to happen with this thing I created. Today I used a piece of 18 gauge to see how that would do (since that matches closer to the actual running board material). Took slightly more pressure to form it, but turned out again very nicely. Don't think I will need to tweak the stamping plates at all, just need to take your time when pressing and watch how things are working. Going to work good for the area's I need to patch.
Just one more quick note, the so called ribs on my running boards at least do not have the crisp edges like they once had (especially on the 46). I can play with the pressure a bit and get the patch to replicate the flattened out ribs pretty well so it doesn't look like an obvious patch in the board.
Thanks for reading this post.
