Elevator and interior


in between the busy times at work and with the family I could do some small works on the project.

Still adapting the trailer

Johan finishing the elevator.

The wings are home!
   
Stript the wings to look at the woodwork.

It fits! only a few cm's to spare.


Making the instrument panel. Thanks Didier for your tools and skills!


Fits perfect.

First test in cardboard before making new aluminium panels


Johan almost finished the elevator, what a beauty!

Work work work, a trailer, a wood work speed course and more work.

 The fuselage is totally stripped and Johan is checking the welds before it will get sandblasted.


In the mean while I bought a trailer to transport the Cumulus.
Had a good deal, for only 250€ I found a Ka6 trailer on segelflug. I had to drive to Baden-Baden for it (5h single), but it's better than making one. I would cost more and take a lot more time!


Some vintage gliders in the hanger at Baden-Oos, Grunau baby 2 , Ka2, Ka6.


The Cumulus being delivered to the company Vandermaesen in Tessendelo where it will be sandblasted and later powder coated.

    
Previous weekend and next weekend I will be following a basic coarse wood & fabric works organised by the VHZ (Vereniging Historische zweefvliegtuigen) this is a vintage gliding community from The Netherlands. www.zweefhist.nl/

            These are my first wood repairs, learned a lot! Picture below my attempt of repairing a hole in a ka6 wing. Not perfect at all I know but, I was pleased with my first attempt 


Repairing ribs


Fuselage is sandblasted, Francis and I packed it up to transport it to the welder for some repairs.


We discovered there are some supporting beams missing. These will be replaced according to plan.




Johan is busy on the rudders, removing all the fabric and paint. Inspecting and repairing if necessary.
The 2 ailerons are finished and ready for new fabric, now the rudder is being stripped.

The check up and first work.

I know... the glider was retrieved from the storage place in 2016. So why the long wait until the start of the restoration? Let us say building a house, having 2 kids and building my garage/workspace were the first things on the list. 


Before I start to work on the Cumulus I want to be sure it's worth all the effort.
A master/guru in Belgium if it comes to wooden gliders is Johan Kieckens, and it just happens to be that Johan is a good friend of Harry. 😄 Here Johan is inspecting the wings and fuselage.
The one on the ground is the original left wing with water damage.

Inspection of the metal tubing.

First assembly since 1967-8?

A test assembly with the left wing of the "baby cham", with just a small margin but it fits!


After the inspection and assembly Johan gives a GO! Let's work! 😄
Johan offert to help me by renovating all the rudders, in the mean time I will take care of the fuselage.

Moving the fuselage to my garage, Harry ready for the trip!

Bringing the rudders to Johan, they just fit inside the van.

Fuselage being stripped

Some lost and found in the fuselage

Almost done!

Johan working on the ailerons

The aileron from the Babycham is in very good condition and only needs new fabric.
The original one is glued with casein glue and needs to be taken apart and glued back together.

Inside the aileron of the babycham, looks like new!









 

Busy summer but not for the Cumulus... , interior panels and hinges.

I made some CAD drawings to design the new interior panels. Powerview helped me to CNC cut the panels. Powerview  Due to some repairs we had...
