Take a candle,and soot the back of the iron. Put it into the plane and tap down the wedge. The soot will print black where it touched. Carefully cut off the blacked areas until you get blacking all over,as much as possible.
The 18th. C. planes we made had these THIN 18th.C. irons in them that the blacksmith's shop made. I never liked them. They chattered,and had to be fitted like I've described. They were stingy with metal in the 18th.C.,since it was refined by hand,and we just had to deal with it.
