New Way, Der Squared Max Build, Part 4, Nose Cone Forming

The nose cone shoulder and exposed sides will require some forming to fit the tube.

The shoulder starts square but needs rounding to fit inside the slightly rounded tube corners.

Round a bit, and check the fit. In the right side picture the edge of the tube is still depressing the corners of the balsa shoulder. More rounding is needed.

After the shoulder is fitted,

The sides of the nose cone will probably still overhand the tube.

Round the sides and block sand the flat side surfaces until the balsa is even with the sides of the tube. 

To somewhat match the Red Max nose cone,

The top and sides of the nose cone are rounded.

On the left, I've just started to round over one side of the nose cone tip.

On the right is the finished shaping. Just a bit of the sides have been knocked off with 220, followed by 400 grit.
