Warner, So no vinegar for you? What kind of oil did you use and did you stick with the brush/wool or also use the angle grinder? Also, Your Grandfathers double bit is beautiful, great job. Did you fill the PVC pipe with linseed oil and let it soak, if so how long?
Your axe is a great tribute to your Grandfather. My Grandparents were farmers. In particular they raised chickens, sold eggs, sold vegetables, and also grew/sold tree's. Growing up, all I did was work with my Grandfather, particularly trimming, shaping, and cutting down trees. The axe I'm refurbishing is the axe my Grandfather used to use. He told me I had to learn the traditional way before I could appreciate the modern chainsaw..... His health is really starting to deteriorate so I am trying to get this axe done for him before he passes.
I really appreciate the advice you all are giving me!!
