    Website distraction yesterday in a good way.  I had found some details of the two kites that were raffled in aid of the Bristol Kite Festival 2009.  They were in the original JMH design from 1991 but in the 1.5 format, one yellow, one blue.
    After a bit of further research I found some images by Laura Berg from Long Beach WSIKF 2009 and Laura was able to send me higher resolution versions for the web site.
    It was good to pin down that episode and to be reminded that Rich Comrass who Jake and I met in Miami 2013 was one of the winners of the raffle.
    It may now be possible to fly kites individually depending on the interpretation of the new rules that are coming into effect during this week.

    Cervia would have ended today and the lilac bush in the Hackney garden here has begun to end its glorious spring show.  Still haven’t started the Tetraeder exercise but the weather has not been great this last week.
    The 1992 Rev 1 re-make project is now in hand.  Martin Lester will sew the sails and Revolution will finish them as has been our practice.  They may be finished in time for any surviving Autumn events but probably will only really get used next year.  Something to look forward to, anyway.  It is quite likely that we will also get the fourth Rokkaku made as well, to complete the set.  Not sure that my sewing skills are up to that yet so probably get ‘someone else’ to do it!
    I have laid off the JMH kite repair works in the last few weeks and intend to pick up on that soon hoping for a slight lifting of restrictions over the summer.  One issue that I have encountered is figuring out how to remember what needs to be done and to keep track in some way.  Getting spares organised and ‘in place’ is also needing further attention.  That is a useful reminder that JC may also have some Rev SLE spares that could be very useful for some of the JMH kites, notably the early 7m Delta which needs replacement for broken bamboo spars.

    So, that is the sixth week with no flying.  Berck would have completed and Cervia would be well underway!
    Further work on the website through the week so there are now 29 event pages and 25 kite and banner pages.  I have set up an entry page with a copy of the introduction page from about 1992 along with the storyboard I prepared in February 2020.  The index has been reduced to five headings, some of them toggling with context.
    The good news this week is that JC has located the Blue (Ultramarine) Rokkaku from the 1992 set of four.  That means that only the Red one is missing now.  He also confirmed that he has the Flexifoil sails.  They are illustrated on the c1992 page.  Not sure what we would do with them but great to know that they are also not lost.  We’ll certainly get them photographed when the opportunity arises.

    Another diary entry for my benefit as much as anything else.  Further work done on the Decs web site during the week and it now seem that a further re-build is needed to reflect an emphasis on the visual elements of the events recorded and the kites.
    I’ll probably look for a visual splash screen and take it from there.  Some elements may be condensed…
    The easterly winds persisted all week so it would have been quite a challenge at Berck but at least mostly sunny!

    I was completely preoccupied yesterday with web site updates using images that Davide Baroni had kindly sent.  They are from Cervia 2014-2019 so plenty to be configuring with a few of my own images for context.  Today Marian Linford has sent a whole set of images from Cervia 2016, so more to do!
    Light wind yesterday which would probably have meant an onshore sea breeze at Berck.  Today and for the rest of the week it looks like easterly winds will prevail so it would have been quite difficult for kite flying.

    12-22mph SSE with clear blue sky would have been a perfect flying day so that is one day down to the lock down, rather than the weather.
    I did do my normal weekday 10 miles on the bike, except, of course, going around Victoria Park rather than through it!  There were quite a lot of cyclists and runners in the parts of the ride where I do not usually see anyone at all.
    I had thought that I might do some Tetraeder building today but did not quite get to it!
    On the web site I ended up scanning colour prints from a group of early festivals so I now have some images of the kites to work with as well.  Too many of the early digital images were just too small for the storyboard idea.

    Strong NNE wind with wintery showers would not have been particularly enticing for kite flying on Blackheath today.
    So, some more imagined launches and thoughts about further material for the web site.  I have looked at some of the notes I made at or after events.  It can be a strange shorthand for what was a very focused activity over periods of days in some cases.  The routine in Cervia 2014 is a case in point particularly as Davide Baroni is posting images from his extensive catalogue on Facebook.
    I’m thinking that a ‘storyboard’ pdf of the JMH Rev designs would be a simple solution given that we do not have many high resolution images of the older designs.  Just about getting geared up to do it alongside the various little bits of maintenance needed on JMH kites!

    While taking the air, going for a walk, run or cycle ride may not be prohibited in London just yet it seemed appropriate to show restraint hoping that more stringent rulings will remain distant.
    So virtual kite flying only today after another week of consolidating records on the web site.  The accumulative record is much more impressive than the constituent parts.  I like the idea of gradually being able to populate the records of past events, maybe only with a couple of images but also with written memories.  Interesting to have a record of weekly notes over the last 10+ years to hand as well!
    If the weather remains fine I might start on some back yard Tetraeder training.  There may just be room to get a flyable unit built even with zero prospect of a launch.

    Another breezy day, 15-30mph SSW, mostly cloudy but with the odd flash of sun and blue sky.
    RSS sails were comfortable and today, even with only three fliers there were some called moves.
    We put together the JMH Flare Kite 1986 as it is almost the last kite to have a page set up on the site.  (Once done I will start on the Rev designs.)
    The wind was outside the comfort zone but it was useful to try adjusting the bias that appeared in the stronger gusts.  The adjustment required is less than a dowel peg so I started to shift the bridle line.  The first step in this respect was not enough but the line was marked for future reference.
    I have been considering making plans for a Malinski Tetraeder session but that will depend on weather conditions and if outside activities are permitted in the coming weeks.  A slightly desperate prospect really!

    Having been watching the forecasts closely I managed a circa 10:00am arrival on the ‘Heath’.  After a short wind check stroll I set about preparing the JMH Della Porta 8 Rhomboids for another ‘strong breeze’ test.  The intention was to use a secure anchor as the kite was walked into the middle of the wind window before launch.
    We were almost successful at the first attempt but the pulling power of the kite was somewhat more than I had anticipated.  It really needed a ground anchor in flight.  For the second launch I used a longer flying line and was happy for assistance in getting the line onto the ground anchor.  Once launched the kite did occasionally wander with the shifting wind and the indications were that it did need the actual wind speed available.
    We did keep the kite flying long enough for me to feel confident to leave the ground anchor and check the kite from underneath.  The spars were certainly under some stress!
    When we ended the flight we waited for a slight lull in the breeze, unhooked the flying line from the ground anchor and walked forwards.  The kite floated elegantly to the ground and tipped over to lie flat with the bridle lines on top.  The windward edge was secured and we wrapped as planned.  Thanks very much to Martin and Maggie for your assistance today!
    After all the excitement we then flew RSS sails until the forecast thundery showers closed in from the South West.

    Finally got out on Blackheath today in bright windy conditions.  RSS Rev for a while getting a feel for the breeze which was often as little as c12mph but also sustained gusts probably well over 25mph.
    I decided that although the conditions were a bit extreme I would try to fly the JMH Della Porta: 8 Rhomboids 1993.  Apart from anything else learning the set-up can only be achieved by doing it.
    There was a moment of anxiety getting it out of the bag as the elements did not fall free, seeming to be inextricably tangled.  Fortunately appearances were deceptive and the ‘unfolding’ resolved the apparent tangle leaving the bridle lines free to the comb.  In windy conditions the windward ‘edge’ needs to be secured at all times.  I had set a ground anchor at almost right angles to the kite and the wind direction.  Once the spars were set the kite was held up on its edge allowing the bridle to be combed out completely.  The kite was then held flat on the ground with a ‘pin’ through the top centre join point while the tails were attached.
    At this point I made a ‘mistake’ and as a result a spar was broken and no flight was possible.  In lifting and turning the sail in ‘high wind’ the bridle needs to be secured statically, that is, to a ground anchor.
    Wrapping the kite was done with the ‘pin’ through the top centre; removing the horizontal spars first but leaving the centre of the top one in place until the verticals were split in two and the lower sails folded over.  The loose bridle lines were wound around the sails up to the comb and remaining plaited bridle lines.  The kite was put in the bag followed by the plaited bridle and finally the loose spars.
    I’ll fix the broken spar during the week and maybe try again next Sunday, subject to the weather of course!

    So, it was the third weekend where conditions were simply not conducive to ‘kite flying’.  20-40mph was forecast and it certainly sounded like it in Hackney!
    I was planning to set about repairing the JMH full vents but got distracted by the new line of development on the web site.  In addition to having started to set up pages for the individual JMH kites I have also set up some event pages as follows:-
    https://www.felixmottram.com/decorators/eventpages/Cervia_2018.html
    https://www.felixmottram.com/decorators/eventpages/Cervia_2019.html
    https://www.felixmottram.com/decorators/eventpages/Cleobury_Mortimer_Shropshire_2019.html
    I do have sets of images for a couple more events and have established a reasonably straightforward workflow for the future.
    Maybe we will get to fly kites next weekend.

    And then it was wet.  High winds had been forecast but did not really materialise.
    So, preventative maintenance on the 2007/8 Rev 1 stacks today.  All leading edge mesh edges oversewn with a three step zig-zag stitch.  There were not as many actual breaks as I had anticipated.  Maybe there are more on the 1.5 stack?
    We managed to get a peculiar wrap in the stacking lines of one four set.  Not yet resolved but shows that it can be done!  After un-tangling the JMH Double Malay stack anything is possible!

    The synoptic chart from the Met Office on Wednesday 5th February was clear that the isobars would be tightly packed today and so they were.
    No thoughts of kite flying but a bit of weather spotting via the webcams at Lyme Regis, West Bay and Polzeath.
    The day did start though, with a bit of knot tying, roping in a rotten fence post in the back yard…

    Brisk WSW breeze 17-30mph so 1.5 RSS kite for me today…  Out of the comfort zone for anything else really so no SLKs today.
    Terry Riley’s album Assassin Reverie track Tread on the Trail proved to be an interesting accompaniment for two fliers.
    Having completed the rigging for the Peter Malinski Tetraeder earlier in the week thoughts turned to configurations.  Having done one initial drawing it became apparent how versatile the system is and just how many variations are available.  It will be fun translating back into the configuration of the spars and connectors as they are one step removed from the sail shapes.
    The team will be doing the first four days at Berck this year to leave days available for Dieppe.  I am thinking about Fanø but suspect that it would be best left until we are more familiar with the JMH kites.

    There was low dark cloud and some drizzle leaving Hackney but the low cloud had broken south of the river with a bit of sun breaking through occasionally.
    Steady southerly breeze probably about 10mph so full vented 1.5s with green race.  A bit of Bersarin Quartett to get ‘in the mood’ and then I was intent on putting together the JMH Double Malay stack.
    I had a dim recollection that it had been put away hastily ‘the last time’ but had not fully appreciated the consequences of that!  It took almost two hours to get to the stage that the individual pairs of bridles could be addressed.  At that point the forecast rain was approaching fast and despite a hasty wrap it was on us before we got to the vehicles.
    It might be a bit frustrating when things don’t quite go as smoothly as hoped for.  The image posted this week of the Double Malay stack flying at Fanø in 2009 was an inspiration.  We’ll get the flying images and video in due course!

    Just enough breeze for Zens with green race but not much else today.
    I had taken the Peter Malinski Hex stack pilot copy as more work is needed on the bridle.  It was not to be!  Yesterday I had been working on the connectors for the Malinski Tetreader.  40 or so still to do so that is 120 knots to tie before starting to fit them; 4 to each of the 35 sails.  The line I was using was being re-cycled from the 2007 JMH design Rev 1.5 bridles.  I do have a reel of bridle line somewhere!
    I was travelling light today as my normal vehicle had been hit by catalytic convertor thieves during the week.  Not all cars are kite kit friendly.
    Still waiting to get final confirmation for Berck and Cervia but plans are mostly in place.

    There really was a brisk SW wind this morning despite forecasts suggesting otherwise up until about 24 hours previously!  While there were quite extended periods of 10-15mph it did blow c30mph quite often during the time we were there.
    So RSS Spiders 1.5 were just right!
    In the circumstances I was not ‘brave’ enough to attempt to put up the JMH Double Malay stack 1994.  We have flown it before but not with a good sunny backdrop such as we had at times today.
    We flew the RSS kites for a considerable length of time, silent mode only with accompaniment from Terry Riley, Steve Reich, Kronos Quartet and Bill Frisell/Thomas Morgan.
    The approach to the northbound Blackwall Tunnel was stationary so I took the long route home.

    A bit of a grey day again but there was some SW wind and the drizzle I saw driving towards Blackheath held off.  I.5 full vents with green race were comfortable but mid vents would probably have been fine.
    I had hoped that Jake would be able to join us today for the first un-wrapping of the JMH Asymetric Kite Stack 1995.  I had brought the kite along with some 2m lengths of dowel in case of breakages and as the ground was not wet and the wind speed felt low enough we did go ahead with assembling the ‘structure’.
    I could not quite feel the ‘lift’ of the stack initially and while we did get two launches there was something amiss.  On reviewing the video it was clear that there was a configuration issue with the front set.  We had a similar issue with the Triple Malay stack on our first flight of that composition.
    We have received the formal invitation to Cervia and some of us have opted for the early flight out of Heathrow this year as there was a significant price step already.
    Scarborough is not happening again so we are looking at other options now to fill out the years events.  Billing near Northampton is a possibility even though it is the week after Portsmouth.  We might consider other events in the West!

    Southerly breeze, some sunshine and blue sky in parts today.  The forecasts were about right with a base speed of about 4mph - 8mph.  Full 1.5 sails with race rods and a mid-vent, just because!  Nothing called as is usual but we did get to discuss events for 2020, just a bit.
    We put together the Peter Malinski Flare Kite (ex Hamburg) with its substantial tubular frame in c120cm units, so c240cm high in the four vertical sleeved pockets with press stud closures and the c360cm horizontal secured by loops at the sail edges and substantial ties at two further points at the back of the sail.  The sail pulled tight very neatly and looked very flat overall.
    The kite felt heavy on the ground but as soon as the windspeed threshold required was reached it took off like a rocket with a very smooth linear trajectory.
    I very much like the ‘kite shaped’ (Eddy) graphic of this kite.  It should look very good with the early JMH Delta kite…

    A fairly consistent Westerly breeze, about 10mph so full vented with green race again.  The stronger winds stayed to the south of the UK this weekend.
    A short fly with accompaniment today and then we set about putting up some sections of the JMH Rhombus shaped kite train from 1985.
    I have re-strung the fifth and sixth sets with 4mm polyester braid as the 3.5mm had been overstretched.  We only got as far as the three top sets today but even they needed an anchor point really.  The Eddy kite that I had made as a pilot for this train worked fine even if it did dive vertically down on one occasion.  The stack oscillated in its own rhythm with the pilot mostly taking a different line.
    I have uploaded a short video here:-

    SSW at about 12mph so 1.5 full vented with green race this morning.  It was sunny and a mostly clear sky so I was hoping to do ‘something’ with JMH kites today!
    After a gentle warm up fly it became apparent that we were not going to get a ‘full’ team by any stretch of the imagination.
    As the overnight rain had soaked in and the steady breeze had taken any remaining ‘wetness’ off the grass it was only slightly muddy underfoot.  We staked out the Double / Single Eddy stack and proceeded to untangle the kites and tails and set the spars.  A third pair of hands would have made things easier but I really wonder how Jørgen managed by himself.
    The stack flew very well indeed and we discovered how to take it to the edge of the wind window in order to untangle tails.  We did somehow lose a spar from one of the front kites but this did not appear to affect the flight of the stack.  There were a couple of issues with the threading of the replacement split rings and one spar pocket requires re-sewing.
    I was able to take a whole series of images and have posted some of them on Facebook.  I’ll update the Decs Collection site shortly.

    WSW 17 - 34 mph but mostly sunny rather than cloudy.  RSS kites were fine, just a little bit noisy in the stronger gusts, merely a sail rattle, not a roar!
    Not the wind for flying trains but we did unwrap the 2 square metre black lifter and fly it from the bridle.  It seemed to be well set ‘out of the bag’.
    I also pegged out the top few sets of the PM Yakko Stack in an attempt to find out how much lift these sails can develop.  They were certainly ready to go but the top sail really needed stabilising.  The pocket sled from Vienna would have been enough but it was folding up in the strong breeze.  (I wonder if a spreader could work here?)
    The 4 and 5mm braided polyester line for the kite trains arrived last Tuesday and two sets of the 1985 JMH train have been re-strung during the week.  The dihedrals for the early JMH kites should arrive during this next week.  I’ll use one of the prototypes to fix the Double / Single Eddy stack 1989 in the meantime.  The on-field fix in Cervia has not actually ever been tested!

    NNE breeze today, fairly steady and probably about 10 mph so finally a change from the Zen Autumn.  Full vented 1.5 with green race was just right.
    The sun was directly in our sightline and there was a slight warmth when the breeze eased.  When there was cloud cover it was distinctly colder.
    I had hoped to fly the JMH Double / Single Eddy stack 1989 but it was a bit too muddy and damp underfoot so we flew the single Eddys that I put together recently that need further tuning.  One of them can be finalised now, the other one was still showing a bias until I resorted to the same fix I used on the field a couple of weeks ago.  As then, completely counter intuitive.
    We flew until the sun re-appeared and I noticed again that the grey fabric stripe can catch the sun and appear to be brighter than the white fabric.  At the same time the shadowed white ripstop appeared to be sky blue.
    The prototype printed dihedrals for the early JMH kite compositions have arrived and I am hoping to finalise an order soon.

    Foggy in Hackney first thing and on the approach to Blackheath from the Greenwich Peninsula it looked as if it was foggy at the top of the hill.  It was grey and gloomy on arrival and very wet underfoot but not actually foggy.
    Wind from the south was light, probably 3mph to start but as the cloud lifted and brightness approached so the breeze increased; slightly.
    So, Zens with green race once again.  We did spend quite some time today meandering in close formations occasionally with Terry Riley as accompanyment.
    I had hoped to look at the Malinsky Yakko Stack that came from Hamburg and as there was eventually a bit more breeze c5mph and some sunlight we did make the effort to switch the individual sails and see what transpired.  There was not enough breeze to launch directly so we put the 145cm Malinsky Eddy in place as a lifter and almost got a result.
    The lifter was only able to move about 15 sails but when they caught the breeze the rest of the train was momentarily, at best, in flight.  Successive attempts were probably significantly weighed down by the wet sails.  A good start, none the less…
    I also tried the Hex Pilot with carbon rods (ultra light) but although there was just enough breeze further work is required on the bridle.
