I've got a No. 8 Stanley jointer that I love. I've always had a 25 degree grind on the blade with a slight 1/64th radius. I will be jointing some two inch thick stock and wanted to grind a straight bevel across the 2 1/2 wide blade to get good continuous contact on the gluing surface. After an hour of trying with both my Tormek, then a single wheeled grinding jig with both sandpaper and glass and water stones, I couldn't get the radius out of the blade.
I finally checked the back of the iron and found it to be slightly cupped. This was surprising, since the plane has had little usage and is in new condition.
Anyone know where to buy a replacement blade that is flat?
