The kit supplies one tail cone shroud printed on cardstock. I rarely get a good fit onto both tube diameters with one shroud.
I scan and copy at least three of them onto 110 lb. cardstock. Assemble all three - one of them should have the best fit.
Do plenty of dry test fittings for a smoother final look.
One shroud on the left is a poor dry fit, both ends are a bit wide.
On the right, one of the other shrouds and a better fit. Both the middle centering rings have been dry pressed into the wide end. The second ring is outside the shroud top and gives you an open edge for gluing and a slip fit of the ST-11 main tube.
The lower ring is glued in place, even with the end of the motor mount tube.
I use the flat face of my sanding block to press the ring even.
TIP: There was still a very slight gap in the small end of the shroud. I wanted to increase the outside diameter of the low ring.
I applied a thin line of wood glue. Smooth and even it out using a fingertip on both sides of the glue ring.
After it dries, run a finger around the ring and you'll feel high and low areas. Some 400 grit will take down the high spots.
