New Way Firecat 4 Build, Part 5, Fitting The N.C. Shoulder

Here's the before and after fitting the built-up base to the solid nose cone.
On the left is before the top of the pieced base was sanded.
The right side picture is after the top of the base was sanded flat. You'll want the best fit of all the parts so there will be less to fill later on.





There is a short length of body tube at the bottom of the nose cone assembly. A square nose block fits into it.

Holding it up to the light you can see where the sides of the nose block should be sanded to fit the short tube better.







Here I'm slightly rounding off the corners for a slip fit into the short tube.
