Odd'l Rockets F-104 Starfighter Build, Part 14, Canopy Forming

Relax and take your time on this step! A great fit and good glue bond canopy edge is do-able. 

Wrap some 220 grit sandpaper around the main BT-50H tube.
Sand back and forth in a straight line. Try not to squeeze the sides of the canopy or the edges could end up too high and away from the nose cone.

You know you are getting close when the pen lined sides hang off the edges. Use some 400 grit to knock off the hinged plastic strings.

Use some 400 grit to knock off the hinged plastic strings. It's a little like that thin layer that stays on when you file your fingernails.

Set the canopy on the nose cone. Look closely at the edge contact. There may be some gaps where the canopy doesn't touch.
Sand the areas that are touching the nose cone to reduce the high areas. This should close up the gaps.
When you get close, it takes very few passes with the sandpaper to get the final fit.

The front curve that goes over the front of the nose cone might require a deeper curve. Wrap some sandpaper around a BT-20 or engine casing to make the inside curve sharper.
