From nothing last month to a lot this one!
Festival of Flight
Well, after a long spell of inactivity I finally got some flying done. I was persuaded to go the BMFA midlands area Festival of Flight, by a phone call from Andy Housden; after all Barkston Heath is not too far away from me.
The weather was remarkable for Barkston, well know for it's somewhat predictable weather pattern: WINDY! It turned out hot and humid, with what little breeze there was dropping in the afternoon. The Midland Area Festival of Flight is like a mini one day UK Nat's without the crowds and commercial aspect. It certainly doesn't suffer for that, as everyone that is there, are either competitors of interested in competition. Only problem I found was a lack of toilet facilities, there seemed to be only one, near the entrance, and not where it was shown on the map, so I missed it first time round. Not being equipped with a male member to point at a convenient hedge, means finding somewhere to squat can sometimes be a somewhat drawn out process :(
The outcome of my flights was a bit predictable having had no practice at hurling a model at a carrier deck since last year, from a locked up hook on the first flight, not judging distances properly, having the lines damaged, to running out of fuel before I could rescue an overshoot landing. Thanks to everyone being allowed 4 flights, I managed to get the last one together enough for a fifth place out of seven entries. The day as a whole though, made up for the sense of frustration. I really must build a decent carrier model without the many vices of the Hellcat; but with four unfinished models lying around, starting another one would be suicide, none would get finished.
During a midday wander down to the speed circles, I tried to photograph a pulse jet being started. It dawned on me at the last moment that at close proximity, this was bound to be a somewhat noisy experience, and my ear plugs were in my handbag back in the car..! Well I can take it; I'm brave, or stupid depending on you point of view. The resulting shock wave, left me feeling like I had been punched in the ears and was suffering with concussion. How sailors coped with firing cannon in years gone by I can only wonder? Mercifully this is only for a few seconds, and I have suffered worse photographing bands standing in front of bass speaker stacks, when I would ended up getting tinnitus that lasted until the next day; hence the habit of always carrying earplugs with me. They are also good for interminably long trips on public transport surrounded by screaming hyperactive uncontrolled children too; the sort that should have been strangled at birth along with the parents, and the afterbirth kept and nurtured instead. I love children; but I couldn't eat a whole one... :)
Back at the carrier circle we spent some time examining a Great planes ARTF 'Corsair', that had been converted for carrier use. apparently with great ease; the only big mod being fitting an undercarriage. Also converted to two line electronic signalling, using an old RC outfit. Apparently old SANWA kit is good for this, as it has large discreet components that are easy to access and solder onto. Lot of food for thought, and very tempting. BUT! I must be strong and not give into temptation until some of these other models are finished: as if I would! LOL
Now having to replace a damaged line, it might be worth showing the performance I have to go through to make them up to length.
Please excuse the appalling state of decoration in my flat, a result of me hating decorating, having no money, and no physical strength to move furniture about to get at walls and floors; when you live in a confined space there is just nowhere to move things to. None of this has been helped by living with a succession of partners that just fill up my space with junk so I can't move, causing me to loose all desire to do anything about it (got an nice clean pad in SL though. LOL). Somehow, staying sane, alive, and keeping myself clothed and fed has seemed more important. I live in my head (and now the Internet as well) anyway, so it's not difficult to ignore it. C'est la vie.
The are three phases to my line making process, (1) get the length approximately right (as per pic's), (2) make up one set of ends, (3) go to the field and measure the exact length, then make up the remaining ends, marking them to match my colour coding on the existing made up ends, (4) at home make up all ends to a finished state and dip in the appropriate colour paint for identification and weather proofing. As you can see, not straightforward, but I have never had an line end failure, and my lines last a long time, one pair I was surprised to work out, about 35 years and still in regular use. I always use stainless multi strand, the ends are sleeved in either aluminium or brass tube: bound with copper wire or fuse wire (easier to handle), or thread; wound with tissue paper strip impregnated with glue, anything from Balsa Cement to UHU Glue (preferably something that doesn't dry hard like epoxy or cyano'), the tissue is wound past the end of the binding to spread out where the load is greatest at the change in section.
It should be easy to substiture heat shrink tubing for thre paper/glue wrapping, but I always forget to thread the sleeving on before binding the lines. Stupid woman!
I received another email from Charlie Stone in West Australia, more of Charlie's excellent high quality work can be seen on the Friends Pictures page. My jaw just drops at what Charlie gets up to.
Just a quick note to say hello and show you one of the things that I have been up to of late. I am currently playing about with a fairly vintage engine. It is a Westbury Kestrel .29 that was made in 1937. I have plans to put it in the air, but as it was built as a boat motor it had a flywheel rather than a prop driver, so I have yet to make the prop driver and a new set of rings for it. The prop driver design has a 5/8th inch diameter hub, so I will also have to do something about making a prop that can stand having a giant hole through the hub. The engine was built as a spark ignition engine for 3/8" spark plugs, but I want to run it as a glow motor. The difficulty with that is due to the head thickness (I don't want to modify the head) I can't use an adapter to fit standard glowplugs so I have had to make some 3/8" glow plugs (photos attached). I believe that in the early days you could actually buy these, but sadly not any longer so it is up to gadgeteers like me to do it at home.
I seem to have lost part of the text about the use of a re-wound mains transformer, but when I enquired how Charlie had spot welded the element in place he replied thus,
It works as planned and sticks the wire into place. I have made a few normal sized plugs and re-elemented some commercial ones already. It wasn't done for any commercial purpose, but because a self styled expert told me that it couldn't be done.
Nice one Charlie :)
Regarding the Internet I mentioned above, this may be of interest, and, or, amusement to anyone with a broadband connexion. The following is an email I sent to Virgin Media, as comment on their service.
Also during the conversation quoted below, I had the double annoyance of being called 'Sir' every other sentence I know I don't have a particularly feminine voice on the telephone, and it gets worse when I get angry, but the person on the other end is reading a script, with my title on it, so should get it right. Even when pulled up about it, the said person carried on calling me 'Sir' . I have even heard the same thing in supermarkets and shops said to other women, and it is not very complimentary. AND neither is being called 'Mate!', when I am standing naked on the doorstep, dripping wet, struggling to cover my boobs and what little dignity I have left with a towel that's not big enough, having been dragged out of a bath by some idiot trying to sell something. AND you can stick whatever it is the you are selling where the sun don't shine, MATE!
HUMMPH! Well now you know.
for comments, and I have two: first Praise.
As a result of that email I received a phone call acknowledging there was a problem with the call centres, and I was not the only one complaining, and I also received £25 of my next bill in compensation for not having the full speed for the time when I should have.
So it does pay to complain.
