Estes Thor Agena B Build Part 29 Tunnels

Use your aluminum angle to be sure the tunnels are glued on straight.

On the lower right, the section of body tube from the removable fin can was taped in place. The tunnel ends were butted up against the top edge of the sleeve. Both ends of the tunnel will be even at 1 1/2" above the end of the BT-60 tube.





After the tunnel glue was dry, the upper end was sanded flush with the end of the body tube.
220 grit was used on a sanding block.

In this picture the balsa adapter is on the left, the body tube is on the right.

This shows the fit of the tunnel ends before and after fitting.
The lower tunnel was just sanded flush with the end of the body tube. Before gluing, the upper tunnel segment end needed a slight angle sanded on it for a better fit at the joint.
