I need a team effort here, I would like to produce a Covid related 12 Days of Christmas, to start us off, here are the first four days:

On the first day of Christmas my true love gave to me, a Barnard's Castle eye test for free.

On the second day of Christmas my true love gave to me, two vaccines waiting and a Barnard's Castle eye test for free.

On the third day of Christmas my true love gave to me, three tiers of lockdown, two vaccines waiting and a Barnard's Castle eye test for free.

On the fourth day of lockdown my true love gave to me, four national policies, three tiers of lockdown, two vaccines waiting and a Barnard's Castle eye test for free.

Please feel free to complete the remaining eight days.

Thread: Prandtl Wing FVT-3

I liked the look of the edf wing next to their logo, apparently they will be revisiting it in the new year, too busy to make it available at the moment. Also, will probably order an exodus as I have the recommended motor and esc going spare, any excuse 😊

Ok, an update.

Wings almost complete, a few points of difference from the plan. I have added some TE section to the ailerons as I wasn’t happy that the top and bottom sheet join would be robust enough without it. I have also added TE section to the third rib bay for the same reason and to strengthen the root joint. The instructions seem to show the 4 inch LE sheeting extending beyond the main spar at the wingtip but the illustrations in the magazine article shows it cut off at the spar, I decided to follow the illustration and not the plan, the bonus is that the cut off section fills the gap in the sheeting at the root 😊. There are no details regarding the servo fitting so I constructed a box between the ribs with square section balsa to accept the servo holders (from Banggood).

I will not add the top LE sheeting until the wing halves are joined and I will probably add a centre rib to support the sheeting aft of the spar. Regarding the method of joining the wing halves, it appears to rely on a 3/8ths medium hard balsa sheet in the space between the first ribs and the upper and lower spars, a support for the front wing locating dowel and the leading edge joiner. Nothing extends beyond the first rib on each side which makes me a bit nervous, normally used to a ply dihedral brace extending to the second or third rib. I will probably add a ply brace to the trailing edge and reinforce the centre brace by laminating it with some thin ply.

I treated myself to a new 6 inch steel rule last week, and noticed the label on the back of the protective cover it came in. The thing is, which do I believe? Is it precision made, or are all figures approximate?

I think this highlights the difference between accuracy and precision.

The ruler is precision made, so if you compare lots of different examples of this ruler they will give you the same measured figure, however they may not be accurate So you could measure a piece of wood that is actually 15.0cms long with several different examples of the same ruler and get exactly the same measurement but that measurement may be 14.8cm, so it's precise, but not accurate.

Thread: Oily Areas During Model Stripdown

Assuming that the residues left in the wood are the lubricating oil it would probably be better to use Methanol to remove them, not sure how soluble castor and synthetic oils are in acetone or cellulose thinners.

15/11/2020 14:38:50

Has anyone tried using Ronseal wood hardener to strengthen soft balsa after removing as much fuel residue as possible? I believe that it is epoxy based and would probably act as a fuel proofer too.

Looking at a few others postage for an RTF model varied from free from CZ or £0.87 from ES up to £55 from the CN warehouse so it may depend on where they are holding stock of individual items at the time you order.

The point I was making was that the delivery for the same item from the CN warehouse has varied from Free, to £55 then £80, struggling to understand why unless they are controlling demand to maximise profit by varying the delivery cost.

I ordered some servo mounts/covers from Banggood China and they arrived in just over a week. I also ordered Polaris amphibious plane ( I have the HK Skipper and it's great but a bit small and quick to keep track of so I wanted the larger version). That is taking longer but appears to have been shipped after a couple of weeks. When I ordered it the shipping was free, I looked today and the shipping cost if I ordered now is £55!!!! Glad I didn't wait any longer.

Just checked again and delivery is now £81 what the heck is going on?

Also, the LE and aileron facings are tapered from root to tip, so these were cut from sheet after careful measurement.

After much cogitation, the build has begun with the wings just in time for lockdown 2.

dsc_0489[1].jpg

Many thanks to barryt who sent me details of the wing jig which is one method described to construct the wing, however I opted for the second method which was to pin the sheet TE to the board and build off that.

All rib positions were marked on the TE and sub LE prior to construction, the full ribs were glued to the TE first, then the aileron sub ribs and aileron facings. The sub LE was then glued to the front of the full ribs and the part ribs in front of the aileron were then attached. It appears to be straight!

The only problem I have found so far is that the spar cut outs on rib 1 are in the wrong place, but only a few mm out so easy to fix.

Haven't figured out why the spar slots in rib 3 are a bit bigger than the rest, any suggestion?

Should Doreen been Soreen Malt loaves

I'm Soreen, I didn't mean malt loaf, I meant a good single malt whisky 🥃, however malt loaf is a pleasant non-alcoholic alternative.

The most detailed advice so far on gov.uk does not answer things exactly but it does not sound good.

From that website

To reduce social contact, the Government has ordered certain businesses and venues to close. These include:

  • indoor and outdoor leisure facilities such as bowling alleys, leisure centres and gyms, sports facilities including swimming pools, golf courses and driving ranges, dance studios, stables and riding centres, soft play facilities, climbing walls and climbing centres, archery and shooting ranges, water and theme parks,

The detail at this stage can not be expected to cover each and every case, however, the intent to close organised outdoor sport / recreational facilities is clear, and I expect that we fall under that guise. I fully expect that the exemptions for COVID secure sport will not apply during this semi-lockdown.

Then there is the catch all "stay at home except for essential travel".

I am sure the detail will emerge over the next few days.

Just shows you how badly thought out these instructions are, you can't just close stables, you may be able to not give riding lessons at riding centres but people still have to go there to care for the horses.

Some people replace their standard headlight bulbs with HID or LED bulbs which are illegal unless fitted in a type approved headlamp because the beam pattern is incorrect and in the case of HID require headlamp washers and self levelling in order to prevent blinding oncoming drivers.

Xenon lamps require self leveling and washers (and are over £100 a pair for genuine), not sure it's a legal requirement for HID though?

They are one and the same.

I was under the impression that although all HID work on the same principle and are halogen there is a difference which sub categorises Xenon, hence the difference in terminology?

HID lamps work by striking a high voltage arc through a noble gas, Xenon is most commonly used, no halogen elements  involved.

Quartz halogen lamps heat a tungsten filament to produce light. The tungsten would normally gradually vaporise and deposit on the bulb envelope darkening the bulb and thinning the filament to the point of breaking. However the presence of a halogen, usually Bromine or Iodine and the use of a close fitting quartz envelope means that the deposited Tungsten is hot enough to react with the Halogen and evaporate from the envelope keeping it clear. The Tungsten Halogen compound eventually contacts the hotter filament where it decomposes and deposits the Tungsten back onto the filament. A very neat cycle of chemical reactions.

Clocks have changed so sort your bloomin headlights out. Half the cars on the road either have dead bulbs or they have their lights pointed in all sorts of exciting directions. Usually this means they point straight in my eyes and i cant see anything. How do you even end up with bent headlights anyway? has a bloke been running around all summer tweaking them in the night?

Also, main beams are not for use when there is oncoming traffic. Everyone in my area seems to have forgotten this, along with what their indicators are for and how roundabouts work.

Also, if you have stopped at traffic lights or junctions take your foot off the brake pedal, its just plain ignorant to keep your brake lights on when there are cars behind you.
