K-8b

In 2009 I got the opportunity to get a K-8b glider for free.
This glider had been hanging in a toyshop in the middle of Amsterdam since 2000.
It was still complete including its original trailer and all her paperwork but in need of an overhaul.

It was planned to give her a complete overhaul but I decided to leave all the linnen intact as it was still in a good condition. Still there was lots of work to be done, damage on fuselage, wings, tail and canopy had to be repaired, safety belts had to be renewed and instruments and hooks had to be reconditioned.

A good place to start: restoration of the topdecking

This looks better, no more holes and saw cuts

The first big job was getting rid of all the different kinds of blue paint on the frame and the interior of the fuselage. A neutral gray paint was to replace it.

Not every place is easy accessible

On the wings and ailerons several wood repairs had to be done, which meant hours of sanding and fitting before finally glueing could be done.

Almost time to glue the patch in

The ailerons too were in need of some repairs

During the restoration the open trailer was replaced by a closed one formerly used for a Ka-6, but it turned out that the wings do not fit in unless the roof is heightened. So more work to come, but that will have to wait until the plane is ready.

Just 7 centimeters too low for the wings to fit

A new dashboard was built with a mix of old and new instruments and the new safety belts were installed.

Changes to the trailer came next.
The heightened roof has to be extended for the wings to fit in so a lot of welding had to be done.

The wings finally fit but now it turns out that  the overall measurements of a Ka-6 are smaller than that of a K-8 so the stabilizer won't fit in the frame that came with the trailer. More work to be done. Luckily this could be done at home.

Finished and ready to be mounted in the trailer

Still the work is not finished as the K-8's fuselage turns out to be 40 centimeters longer than that of a Ka-6, so either the rails in the trailer or the transport cart on which the fuselage is mounted have to be modified.
