I too watch maidens, and drool, blessed with living 40 m from a boat slip on a clean river.

Written on the back of a fag packet. Vapour to deceive. As for the police. A stretched organisation gets to lose 20% of its manpower, social services offloads a load of Mental Health act stuff onto them cos social services can no longer cope. Then the police bosses go mad. That murdering copper in the met had a nickname, “the pervert”. Now I might just spot that as what is technically known as “a clue”. And they spend time doing vacuous hate crime. Also note Zflyer’s comments. oh, and not a political statement, this government has a fair track record of gaps between promise and delivery. Rant over. oh, just remembered, back in the 90s, I worked for a year or so for a home office organisation, National Strategy for Police Information Services. Home office and strategy is a little like relying on a blind man leading troops towards the enemy. Just look a the codswallop of drone licensing. Ranted out.

I’ve got a pot of that, very good glue, and I’ve used it for hinges . Rubbery glue=tough. But, being a bloke wot has been round the block, you know the answer, 5 minutes to make a test piece, dry it for a day, and break it. Then YOU know, one less fail point.

Arrrr, you get to carry eight times more weigh in the material. Ie your basic wing weight has grown by eight times. That’s eight times the power needed. Airfoils don’t scale, but for practical purposes for small changes like this, they still work. For the structures you are looking at, twice the span, twice the chord, 4 times area, 4 times the power needed, 4 times the weight. So spar size old, changes to new is 1.4, square root of two So the new dimensions are the old dimensions times multiplied by 1.4, wot provides an airframe weight IRO 4 times original. All to get something with the same(ish) wing loading.

I’ve used I use this system (cheap quick, good). I abrade the inside of the tube, so it is grease free. Use a longer set epoxy, mixed very carefully, fill the rod hole with epoxy, (a pin to push apply)and fill the masked threads (same pin). I did a test once. Built a test piece . Nothing fancy for units used in the test piece. When cured, hung a 50 kilo lump, no fails, no fails when I tried push pull shock loading. Got bored. Word of warning. Destroy the test piece. I saw it much later, a half finished rudder control arm. COO goes I. Finished it, installed it, and the penny dropped, why a half finished rudder rod. Chastened, made a new one.

Welcome

Arrrrrrrr, but you have planted a set of memories. Normal for adolescents to change. Do you not remember the time when young ladies became alluring to you, and aftershave rather than eau de diesel, became the smell of choice. But still a memory is still there. And they might one day remember.

Copper sheathing is also nice, can buy on internet. Slide it over the workpieces, pull it longer, so it thins in diameter over the workpieces, and solder on. Neat. Another is take a bit of brass tube, slit it lengthways, and open the slit to nearly the diameter one of the wires, so it can be pushed onto the wires you want to join, using the brass as a spring/clamp to pull all together. Then solder. Trick is to pick the right diamerter of tube so it clamps well.

I can braise wire and retemper, father taught me. Ditto silver solder. Sub 7 kg stuff, wot I fly, 60/40 lead/tin, resin solder, scrupulous clean, helped along by resin flux. I think my iron is 150 watts. No fails yet. Note well Martin’s comment, the solder acts like a glue, not a structural component.

As a guess, they are pinched in and glued, then it would look right. The pinching tool need be no more than a piece of nylon strapping say a 5 mm cable the, or similar.

Noddy, you are assembling a trainer, tool for a job. Now I appreciate pride of workmanship, but you don’t polish a hammer. Tape is quick. It’s reliable. It does not fail, think how you would feel, it’s your only plane, a magnet pulls out.

No, it’s concentrating on the next you do.

I used to coach kids at target shooting, Duke of Edinburgh medals, et al. Standard opperating proceedure for all non strength based skill sport. Tell then how to do it. The girls listen. The boys are off with the fairies. Girls start to win. Patience, no shouting. Girls listen, boys think this is too difficult. Pep talk. Language moderated. To the boys, Are you going to let those young ladies trample all over you gentlemen? To the ladies. You are ahead ladies, mind you stay there. Then they all get learning. Some friends spent a holiday with us in France some years ago. They had 2 kids, 8 and 10 years old, girl and boy respectively. As I had two prisoners for two weeks, I taught them to fly on a HK Tundra. Prize, land my Flair Fokker DVII. They were fascinated by it. The young lady, bit of a natural mind, took eleven days.

I think, think mind, it’s more a pupil trani on a mode and make not used/understood by the instuctors. And they suggest a trani they can grab, or bind to. ie, if you can’t fly it, or program it, how can you teach on it. Hope I’m wrong.

Build a wooden crate, with custom foam and strapping, strong enough to walk on, and drop off a van, and quote to buyer fair actual costs to do the packaging, inc reasonable labour costs. There after if accepted, if you can build the model, the box isn’t a problem. The recipient at least doesn’t get hanger rash thereafter. But I bet it costs more than the glider.

I’ve been (nearly) caught out that way. I started making a written record of every switch use for every model, but it fell by the way side.

Not Newton I think, but Kelvin. Didn’t think “entropy tends to increase in any system” had the same ring to it.

All engines turn all their energy into heat. Efficiency equals wot bit of it is useful to the destroyer of energy, ie the driver. Big, heavy, grunty, fast, SUV s are very poor at energy efficiency. Small, light, boring, slow, gets further down the road. Mind, when I smoked boring equalled you could roll a fag.

As Roy Keane (Man U, Ireland, hard,hard, man said, “sometimes you make the ref make a decision” and live with it.

In fairness, he did ask the camera adjudicator,” I think it was kept up, can to tell me with certainty I am wrong” and was told , “with certainty I can’t.” I personally are intrigued by the logic sequences by which the laws are enforced. But accept the passion drains away.

Just watched that lot. Forgotten what I saw already. Apart from that Scotland disallowed try. Cruel.

Ok, just tax the gas guzzlers

So Erf, subsidise a car that does in the real world, one hell of a lot of miles, and carries a max acceleration similar to a non turbo diesel box, ie efficient and boring, but functional. And recover the subsidy from taxes on fuel guzzlers

The 19th-century French philosopher Frédéric Bastiat concluded, somewhat cynically, that “the state is that great fiction by which everyone tries to live at the expense of everyone else.
