Estes USS Enterprise #1275, Part 22, Rectangle Detail Prep

Here's the back of the die-cut cardstock piece.

Note the crimping. This side will be glued down.

A before and after sanding with 400 grit on a block.

Any raised edges are rolled over with a burnisher to flatten the top.

The edges get a smoothed bead of glue to seal them.

After the glue dries, sand the sides with 400 grit.

Estes USS Enterprise #1275, Part 21, Intercooler Prep

Note - The front side of the cardstock intercooler piece is shorter than the rear.

The die cutting process has buckled the the centers of the intercooler pieces.

I filled the depressions with CWF and sanding. Here the pieces are taped down for a shot of filler/primer.

After sanding the filler primer.

In this picture, the front is to the left side.

There are small die-cut inconsistencies in the length of the inside cuts. All four dowels were cut to fit each individual intercooler piece.

The pairs were pencil marked 1, 2 3 & 4.

The dowels also got a shot of filler/primer and sanding.

Note the tall overhang of the front end cardstock.

This was trimmed down to fit the diameter height of the dowel.

Estes USS Enterprise #1275, Part 20, Engine Mount

The engine mount assembly is pretty standard.

The kit didn't include an engine block. I installed one using a Q-tip to apply a glue ring from the top. The block was slid in until it rested in the glue, against the upper bend of the hook.

The "recovery probe" assembly is held by a second engine hook that clips into a slit in the engine mount tube. A slit is made at the bottom of the glued in coupler.

This upper hook is not glued in. I'm checking the slit and position of the hook.

Here's the finished mount.

A bead of glue was applied to the upper bend slit of the tube.

Estes USS Enterprise #1275, Part 19, The Radar Dish

A hole is made in the radar dish center to fit over the sharpened dowel.

Start the hole by spinning a blade tip in the center.

Enlarge the hole using a small rat tail diamond file. By using a file to open it up, you'll end up with a rounder hole.

Careful, it's easy to make the hole too big. File a little and check the fit. 

Glue the dish using liquid plastic cement.

The "ball" at the end of the dowel tip is a drop of white glue. You might have to build up the diameter of the ball using a few applications of glue.

Estes USS Enterprise #1275, Part 18, Fixing The Vacu Form Cracks

HAPPY THANKSGIVING!

   

Wood glue fillets were used to fill the joint gaps.

Here's a picture from a previous post showing the cracks that started in a thin plastic area. 

The same method is used to fill the recessed mold lines in nose cones.

Squeeze out a drop of medium super glue on scrap cardboard. Dip a toothpick in the drop and drag the tip across the crack.

It may take a few applications to build up and fill the gap.  

After it dries, sand with 400 grit.

It's better but could still show a faint separation later after paint.

Estes USS Enterprise #1275, Part 17, The Homing Beacon

The homing beacon is cut off the vacu-form sheet the same way the larger pieces were.

Ball point pen outline, then scoring the edge.

Break away the sides by cutting and cracking off angled wedges.

The sides are a little rough after the first cuts.

Sand the bottom flat until the edge starts to roll off.

The finished beacon wasn't perfectly round.

The instructions say to sand down the overlap seam 3/8" wide, 1/8" from the rear. The pencil marks show how wide that marking is - too long.

On the left, the overlap ridge is removed to fit the actual diameter of the beacon.

On the right, the fitted and glued on beacon.

Estes USS Enterprise #1275, Part 16, The Hull Pylon

The internal pylon assembly was set inside one side of the secondary hull. A pencil line was traced around the bulkhead.

Contact cement was applied on one side at the pencil bulkhead line and at the pylon doubler contact areas.

Repeat for the other side.

Before allowing the pieces to touch - carefully align. 

The pylon assembly was pressed in place.

Be sure to check that the slots line up at the back.

The secondary hull assembly.

Two small hairline cracks occurred on the forward end of the hull. The cracks formed where the plastic was the thinnest. 

I'll fix this in a later post.
