ASP Ram B Build, Part 7, Filler/Primer & Planning The Masks

Here's Friday's post a day early - the internet at the campground is not running.

On the left is the CWF filled balsa and tube seams sanded to surface.
On the right is after spraying with filler/primer.
Notice how rough the tube is. Some tubes fuzz up when sanding the filler on the seams. This fuzzy surface will disappear after light sanding.

The gray filler/primer shown here is right after spraying, still wet and shiny. Depending on what brand of filler/primer you use - wait a few hours or overnight before sanding.




Two fins - the upper one shot with Duplicolor filler/primer.
There isn't any visible grain, the first fill of CWF did it's job. They don't always turn out this smooth after the single pass of CWF.

The lower fin has the filler/primer sanded leaving very little in the remaining grain pores. This was some quality balsa.











Looking ahead - 
Here's a page from Peter Alway's Rockets of the World.
The upper transition swells out like the plastic adapter on the Estes Nike Apache.
This is going to be an interesting mask!
