You must be very careful when you are sanding this as the cardboard doesn't like to be sanded and will fuzz up and/or layers will peel off. I'm still not happy with Sarissa's choice on the cardboard, something even thinner and more flexible would have been better in my estimation. I'm also of the opinion that more ribs would have been nice in the tail section.
The extra effort is certainly worth it though and if I do another one I think I would use a wall filler of some kind, something that is designed to be sanded down quickly and easily. Tragically there are three tubs of the stuff at the other house where all the remodeling is taking place.
Here is where things ended up:
|The idea; fill the score lines in the cardboard with the modeling paste and try and feather everything else so its a gradual transition and not an abrupt 90 degree change.|
|Here she is ready to be "skinned".|
|Cockpit section, "skinned" and ready for sanding.|
|The tail, "skinned" and ready for sanding. This was the easiest of the three sections to do and I just didn't bother to try and feather in between the cardboard and the MDF.|
|"Skinning" the main body|
|Everything sanded and ready to paint at this point. Its not nearly as smooth as I want it to be.|
