I purchased a blade for use in a wooden compass plane. It has a pronounced 3 inch radius on it because it's used largely for shaping. I nicked the blade and needed to sharpen it but I'm not sure how to do this. The square edge jig will put a square edge on it. Don't want that. Will the SVD 110 work? Whenever I use that thing, I end up ruining the entire blade. Any tips? Thx.
I would suggest making a cardboard template the width and length of the blade. Scribe a three inch radius on one end of the template. Cut out this arc. With the template on the back of the blade, draw an arc on the blade using the template and a marker. Set up the plarform jig and carefully grind away the arc marking. This should restore the original shape.
Work patiently, frequently checking your progress.
Keep us posted.
