I am still a novice wwer. I inherited this tool from my father-in-law. I found out today that it belonged originally to my mother-in-law’s grandfather. So we have estimated that the plane is over 100 years old. I have tried once, unsuccessfully, to set up and use this tool. My mother-in-law also figures that this is the original blade (basaed on some paint that her dad put on the plane).
It could be that I just don’t have the blade sharpened very well; I just recently got a grinder. It could also be that I don’t know what I am doing. So here are the questions
1. Would I be able to find a replacement blade for this planer?
2. The plane is not flat (picture 7). There is a slight upward arc to the surface of the plane. Is this a defect or is this the way that this plane should be?
3. What should that left-to-right toggle do for this tool (picture 5 right above the back handle)?
4. Is this a jack plane or a smoothing plane?
Thanks for the help.
