The wing is now laid on the supports and weighed down after taping the upper sheeting into place...

Time to rig again...

Well, we are catching up now: this was only five weeks ago... (I remember it well, it stopped raining for 5 whole minutes) Laughing

Chris,

The grass is perfect...... MDR

the glider is beautifull too Wink

If I am not wrong, you use red brick as weight during the sheeting. Do you dismantle your workshop [humm]

.
BTW congratulations for this professional building [clap]

eager to follow it on this forum.

No Pat, I dismantle my neighbour's house Laughing

Attention now moves to the front of the fuselage, where it is always best to get some lead as far forward as possible...

Now we return once more to the car body filler...

We use a bit at a time as it can get very hot...!

Almost there...

All we need now is to make a hole for the brass tube that will connect to the tow release...

Nice, your garden is just big enough to display your glider! Do not build bigger Very Happy

Still very nice [amen]

How fast you build.. Impressive, retirement cannot explain everything for sure..
Your garden becomes well known throughout the years with all the models you built and presented...How is your daughter? Am serious :we all saw her when you presented the Petrel.. in the garden :lol:Nice I must say...

A part from our chap JP Voisin comes to visit us during his holidays. I should have the great pride to count him as passenger tomorrow (weather permitting) in the Duo Discus of the club..

Bravo et bonne construction + my Wink

to Sir Barry..

Where the .75mm plywood joins on the fuselage there must be some 3mm sq spruce strip to spread the load. The slots are cut with 3 blades taped together on the hacksaw...

Time now to attend to some of the electrical jobs inside the fuselage...

Now some more plywood can be added to one side...

Thank you Laurent, but we are nearly in real-time now...!

Aiframe is now nearing completion...

Man behind a camera: "Hey, I can`t capture whole wing on the photo! Go one step backwards, please! "

Hello!

Beautiful Airplane (Jean-Marie doit baver! [baaave]

), beautiful video, .... and great weather conditions too! Wink

Bye, Christian

Merci Swiss Chris...the weather has now returned to normal, so now we must apply body filler to the tail end...

cw · Posté le: 09/09/2008 17:21 Sujet du message:

Attention now moves to the canopy...

Cutting it roughly to size. (The canopy is from my Skylark 4 mould which has fitted many models: 2-32, Minimoa, Skylark 4, Dart small & large etc)

Lining tape is used to mark out where to cut. The rule is: 'cut little and often!'

Pacer canopy glue is used to glue the canopy to the frame. Good stuff, dries out to be practically invisible

Now it is all taped down to be left overnight to dry

More body filler now to match the front of the wing fairing to the rear of the canopy...

Beautiful construction Chris.
And so fast, nobody understands how this is possible!

Questions;
Why the hole on top of the fin?
Why a plastic tube in the fin. You are going to install an altimeter?

Harold, the hole in the fin is to allow the fitting of the tube for the TEK probe that connects to the variometer in the cockpit, which compensates for the glider's speed and is supposed to eliminate 'false' lift tones from the vario.

The hole is to allow the fitting and connecting of the small brass tube in the fin after the sanding and shaping process...

Matthieu, the chien is called Henri, and is glider-friendly Very Happy

The airbrakes are of commercial design and have been recessed into the wing so that they are flush to the surface. To iron the Solartex into the openings, a piece of wing joiner bar is heated up with a gas torch and used to iron the 'Tex into place...

For the ends, a piece of square brass tube does the same job...

cw · Posté le: 30/09/2008 21:00 Sujet du message:

To cope with the undercamber of the HQ profile, the Solartex is pricked through and thin cyano placed over the holes to glue the fabric to the ribs. Then, a strip of Solartex tape is ironed over the holes...

patte de loup · Posté le: 01/10/2008 11:55 Sujet du message:

Chris,

Your tip is so interesting, but one think is not clear for, sorry Wink

Do you perform this action (pricking and glueing) after stretching the solartex on the wing or before? [humm]

Thank for answer
Pat'

cw · Posté le: 01/10/2008 18:41 Sujet du message:

Pat, 1st, you must iron the 'Tex to the rib. You run the iron across the rib with one hand and follow with a cloth pressed down to hold the 'Tex to the rib as the adhesive cools down.
This takes two hands, so no photograph!
Then you continue as I described above...

Bon soir Jean-Claude... There are many different manufacturers of polyester filler, this is the one I use. In this instance for coarse sanding it is best to use 40 grit sandpaper while it is still soft, usually 5-10 minutes at room temperature. Then you can use 80 grit to get the correct shape, and 120 grit for areas ready to be primed...
