This month (OCT 2001) we have been concentrating on fitting the aluminium tail to the fiberglass fuselage.


First fiberglass fill-in.
 

Making & fitting the angle plate to the horizontal stabilizer, which attaches the front of the vertical stab.


A thin strip of aluminium (above), gets nut plates and sits behind the fiberglass angle. This ensures the front of the tail is firmly attached to the fiberglass fuse.

 

All the bits have been primed. Either side of the the fin attach plate are two brackets (remade from previous photo) attaching the stab to the fuse.

All bits firmly bolted on, first time we don't have to hold them there.
 

Second stage of fiberglassing to fill in the large gap from where the horizontal stab sits to the bottom of the fuse. Also strengthens the plate the stab is sitting on, considerably.

Putting on a strip of fiberglass to hold a piece of flat aluminium containing nutplates. The stern post of the vertical stab will screw into this to hold it in position.
 

Because our fuselage is not as deep at the back as Van's, the elevators have moved up to where the original fiberglass fin was, which is much narrower, so we have had to add extra skin to fill in this gap.


Extra skin being shaped and clecoed.


Countersinking the holes made quick and easy with this neat tool from Avery.

 

Another handy tool this drill stop. Oh boy, does anyone build an al plane without the Avery deburring tool. We need a second one.

Voila, finished.
 


Riveting on the skins.


Reviewing the situation.


Now comes the unusual fill we need to do up front to make the air flow around the tail without to much turbulence. Here we have cut some flat pre-cast fiberglass and sticky taped it to the fuse in approximately the shape we want. This is to contain the expanding liquid foam to a rough shape.
 

Filling with the liquid foam, here showing it already expanding.

The foam expands to roughly 2 1/2 times its original size. Here is the result of that. As you can see some of the sticky tape has let go from the pressure of the foam.

Peeling away the fiberglass.
 

The foam on this side has finished being carved into shape. Once the other side has been carved and a few more bits of foam added in places then we will be able to glass it over and have nice compound curves for smooth airflow.

This is the first time we have had a chance to fit the elevators and rudder.

Well there is the progress to October 2001, See below to October 2003


Riveting up the first aileron...

...with the second along the way. By now both are complete.


Lish juggling all the pieces of the wing spar.

Doug using the planer on the dash to make the correct angle to fiberglass the front of the plane.

Lisha's back at the wings cleaning out the holes. They're all primed and ready to rivet.


Making a support bow out of fiberglass tto locate the dash.


Using a pre-molded piece of fiberglass we take a look at it draped over the front of the fuse and see if we like it.

We took a piece of foam cut to the correct shape of the front of the fuse and fiberglassed one side. Here Doug is cutting slits part way through, so we can curve it over the fuse.

Draping the piece over the fuselage.

Gluing the piece on with a slow setting fiberglass glue.

Doug in action pounding away at the spar.

The piece is now glued on and you can see the locating support bow that the dash bolts onto.

My Chikita cleaning up the second spar.

Filling in some of the dips to get a nice smooth finish.

At last the Ah Send of the fuse has been closed up

And we have made access holes to connect the elevators.

Most of the Dash details are firmed up now, might put a larger pic next update.

Lisha lining up the wing tie down mount.

Fast action riveting of the angles onto the spar.

Team effort rattling those rivets.

Bought some Azusa wheels the other day, so here was a first test of looking at where undercarriage is going. Note the faithful cradle the fuse has been sitting on had to grow.

There we see 2 ailerons hanging on the wall, on the opposite wall we have the two flaps which look similar.
