Estes Great Goblin, #9724 Build, Part 5, Two Piece Fins

Mentioned in the last post - 

You should sand and square up the edges. Sand enough just to remove some burnt ash. 

On the left is a fin piece right off the sheet showing the laser cut ash.

On the right is a sanded, squared fin edge.

This shows another angled laser cut. 

On the right the edge was sanded.

This is a root edge TTW tab and doesn't really need sanding like this. I use it to show the laser cut diffused angle. 

You will get a better glue bond when some of the dark brown ash is removed. 

Here's a 90 degree sand. 

Using a sanding block makes it easier to visualize.

Sometimes I'll look at an edge like this to ensure things are square.
