Tobias asked about any ill effects of using vinegar. So, here are a couple of pics of the results of an overnight bath in plain old, edible, distilled white vinegar. (straight from the grocery store, 5% acidity) Metal that was not previously rusted shows no noticeable change. Places where there was red rust are now free of the roughness, but are darker gray. There were some blotchy darker areas that are unchanged.Â Heck, I’m only 1/3 the age of these plane irons and I’ve got blotches.
Next: sharpening, which as I mentioned to “Boy” will be freehand usingÂ a course India stone and two finer grades of Arkansas stones. The rounds can be sharpened on normal flat stones, the hollows on rounded edge slip stones.
