Curing Tips
10/27/20
The reason you don’t see much information on curing time is because there are so many variables. Differences in room temperature and humidity will change the duration needed. Also, the type of jig and how carefully the jig is handles will change how much time is needed. NPV needs between 3 and 10 minutes before the jig can be removed from the vane. The actual 100% cure can take days in cooler temps but is usually ready to shoot within 24 hours. A warmer room may lessen the cure time to 8 hours.
Wood shafts are ideal for NPV cement since there usually there are no release agents used in manufacturing of the shaft. Sometimes using a very fine wet and dry sandpaper just on the contact area of the vanes and shaft is a good idea followed by rubbing alcohol to remove any dust. A little trial and error is the best method to get off to a good start.
