I uploaded this file in antique plug forum in reply to a post there about a plug i.d. inquiry and thought that if anyone wanted to see the actual diagram I made after researching Frech's 6 5/8" darter that I gleaned from several different articles I found. These measurements are the exact same as Frech used. I just gather them all up and put them on one drawing. I f I remember correctly I found three different drawings. The only thing I asn't able to actually discern was the total weight Frech used in his plugs. I have used "00" and it works really well in the plug made from AYC. Prior to this I made the darters from maple, which not only cracked but doesn't swim nearly as well. Although they did catch, as Andy Stephenson can attest too.
