Rhombus-Shaped Kites 1985
81 kites each kite measures diagonally 48 x 80 cm
total length of the chain: 158 metres (16 square metres)
Weight: 3.6 kg complete train
after Eiji Ohashi design

Windspeed10mph Blackheath 27/10/2022.

The office at The Japan Kite Association kindly sent a pdf copy of the Eiji Ohashi book which illustrates the basic design.

I wonder if the drawing of variations here ultimately inspired the design of the Asymetric Kite Stack 1995?

Perished rubber bands have been 'replaced' by drilling the rods and then sewing the tails on. (as at 28th March 2019) Some spare long rods are available, ready coloured. Spinning sections put multiple wraps in the line as seen in some of the sets on arrival... Undo top spar pockets, unhook loop and pull twists through to resolve. Eyelets have been replaced where missing using white dacron. (repair tape not sufficient!) 40 spare spreaders made 09/06/2020.

The connecting lines are graded so the order of the colours is partly predetermined:-
Black 5mm, JMH logo printed on front kite.
Dark Green 5mm
Yellow 5mm
Purple 5mm
Pale Green 3.5mm wire like now 4mm 09/12/2019
Pink 3.5mm wire like now 4mm 09/12/2019
Red 3mm
Blue 3mm
Orange 2mm

Jørgen had re-made some of the sets and so preparations are in hand to repeat the process.
The red set are quite a new set so are being used as the model.

February 6th 2022... A template has been drawn for the main sails but the colour strips will be drawn directly on to the fabric.

Sewing in progress.
The nine sets are sleeved in colour marked bags made by Jørgen. The new bag holds all of them and also the Peter Malinski train from the same period plus some pilot kites.

Replacement sails set test flight.

Thanks to Marian Linford for these additional images catching the pilot kite, the replacement Eddy Kite from the Peter Malinski train c1985.

First time out for one section of the 81 kite JMH Rhombus-shaped kites 1985

The kites descend when there is too much wind speed so walking forwards caused the train to ascend
