Marc. I use an electric blanket when bagging wings in the cold northwest. After the final suck-down, Place the lower "beds" on the blanket. Position the bagged cores on top of beds and carefully fold the E-blanket over the top of the wing..... I have never had a warped wing by using this method. I had a "hot box" but you have to store it someplace........... ----- Original Message ----- From: Marc Webster <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, December 12, 1999 9:28 PM Subject: [RCSE] wing layup with hotbox question? > Hello, > > I am about to vacuum bag lay up a composite wing for a thermal duration > glider called the addiction.
