Manufactured 6 propeller lugs which I pressed with a 0.015mm interference each into the extension. The lugs are made from 25Crmo4. The pressed part have diameters around 15.95mm, while the propellerside of the lugs show diameters around 16.2mm. Inner diameter are drilled to 16mm to fit the 3/8" propeller bolts. The overall length of the lugs are 31mm.
