Navigation and Position lights

Yesterday and today I have been looking at two aspects of the wing ๐Ÿ™‚ Well things to be build into the wing.

First, I always wanted to build lights into the wing but have now decided that it would be to obvious or visible using my first idea, of building lights into the wing. Might also have been a bit to hard as I would have had to make some acrylic glass window, shaped to the rounding of the upper surface if the front of the wing.ย Have now decided to put wiring into the wing going to the tip, and mount a flat area, not much wider than the thickness of the wing tip, for mounting a PowerBurst Plus 3-in-1 Nav/Position/Strobe light from Aveo Engineering (see below right).

It has a green and red navigation light at the front, a white position light at the back, and a white flashing strobe inย between (see below left).


I am doing it in a way so I can also later replace them with an higher light output version from the same brand if I want to.ย This model here is the entry model, only used on microlight class planes, well in the US they are. Also doing it this way, it means I don’t have to buy them right now, and can install them later when I want. Also saves me quite some time.


Second, thing I have been investigating is the Pitot tube and its hoses. This tube is mounted in the leading edge of the wing and is measuring air speed. It is going to be connected to the air speed gauge. It is based on the air pressure that builds up when you go faster. Found all the materials needed for this, so all under control !
Also thinking of building one Pitot tube into each wing. One to be connected to the “mechanical” air speed gauge” and the other one to be connected in the future to my Aviation Redundancy Instruments on-board computer.

Installing compression struts

Sorry was too busy trying to install a new insinkerator yesterday.

So back to plane stuff today.

With Nicki’s help, holding the spar assembly while on the fuselage, I riveted the compression strut closest to the fuselage to make sure the spacing is “perfect”. All others were riveted while on the garage floor ๐Ÿ™‚

Also here you can see one of the ribs on the spars…….. ( and Ben, our dog, inspecting my work )


Also have a look at the ends of the spars below. Squashed to the size of the tube going along the edge of the wing and at the right angle ( I hope ).


Compression strut brackets

Today I mounted all the fittings (see above right) onto the spars (see below). Then I adjusted the carry through (see right) sticking out of the fuselage where the spar’s slide on to. I now have 2″ sticking out.

Then I cut the 8 compression struts to the right length, so that the 2 spars line up perfectly with the carry through on the fuselage.
Drilled all the holes for the rivets that will hold the struts onto the spars.
Just need to get a few new rivets as the ones I have are too short.

More tomorrow ๐Ÿ™‚




Spar tangs

Finished the last spar, and started drilling holes in the tangs, before mounting them on the spar. A machined piece of aluminium is used see below,that will be riveted into the compression strut, joining the two spars. Two types of tangs are visible here, the thinner ones for the internal (in the wing) drag and anti drag cables, and the thicker ones for the landing and lift cables.

Will show you tomorrow what the fully assembled spars look like ๐Ÿ™‚



Henk van Hoorn, The Netherlands

Henk, did fly his Bleriot in the centennial Channel crossing together with Pascal Kremer, who flies a Bleriot made from a kitset like mine, a few years ago ๐Ÿ™‚
Hi Gert,
Mooi project en veel succes gewenst. De kist gaat er steeds beter uitzien en het gaat vast perfect vliegen.
Mocht je belangstelling hebben voor inside info bv trim en wat je kunt verwachten tijdens het vliegen, mail dan gerust.

(Hi Gert,
Nice project and good luck with it. The bird is looking better every time, and will definitely fly perfect.
If you ever need inside information on what to expect while flying, please email me.

I asked him about that Channel crossing and that was definitely one of his highlights !!


YES back on the wings ๐Ÿ™‚


After building all the ribs a few months ago, I now started working on the spars, that together with the compression struts form the skeleton for the wings.ย What I am doing now (see below) is drilling the 4 holes in each spar, where the compression struts are mounted. In order for all the holes to be in the same direction, I clamped the spar in the middle and basically move the electric drill press around.

At the end of the spar is a small extension that slides into the spar that I squashed, by heating it up a little and using the hammer to deform it. This is done now so I don’t have to do it later when its assembled. The tips are narrower as a 3/4″ tube is riveted in there, joining the leading edge of the wing to the trailing edge of the wing. You can just see one of them on the right side of the photo.


The wing shape I am aiming for is shown in the drawing below. It is part of a drawing of the Bleriot that did the original Channel Crossing in 1909. This wing is a wing warping one. My one will have ailerons.

Very nice shape I think ๐Ÿ™‚


Starting the Engine BBQ day

We had our Starting the Engine BBQ today!
People here were brother in-law Andy and his wife Sally, mother in-law Lesley, step son Sam with his family, Ayden one of my plane friends, 3 of my colleagues Phil, Warren and Andy with his wife Katy and son Bexter, the neighbors David & Ruby, Claire & Nigel and their kids. And last but not least Nicki (the wife ๐Ÿ™‚ ), and Lidia and Rutger (daughter and son).

Here is Lesley’s (my mother in-law) report on her website:

Today was the official “Starting the engine” BBQ at Nicki & Gert’s home. It was a beautiful afternoon – sunny and warm – and a great lunch was served which all enjoyed. There were probably about 25-30 people present for the big event. And then it was time. All the males present were busy asking questions or giving advice while the females stood back and waited for the action and it wasn’t long before the action began. Everyone was most impressed and it all went off without a hitch. I believe there was a minor hitch but that was men’s stuff and I think got sorted fairly quickly.

Here are a couple of photos of the event.



And Nicki’s reply on her website:

Yes – great day – the hitch isn’t fixed yet but easy to do apparently. Gert was pleased with how it all went and I was pleased there was enough food ๐Ÿ™‚
And the sun was a bonus – I had made Gert and Rutger go and find firewood to light a fire outside for people to stand around, in case it was cold but that wasn’t needed. And just after the last person left the southerly swept in. So all good. Thanks for coming Mum and Andy and Sam (the Seadowners who were there).

So yes all went well.
By the way, this hitch is the contacts of the distributor in the magneto’s. Looks I can just unscrew the little nuts out and put new ones in. Hopefully they come out OK, and don’t have to use the “spark erode” people.
Just got a video that Sam made posted on YouTube. Thanks Sam, looks great:

At some stage you see me checking the temperature of the 5 exhaust’s as I am expecting that one of them isn’t firing. And yes I was right. Cylinder #5 didn’t fire. Later we found (with the help of Warren and Phil) that the contacts in the distributor in the magneto had worn a bit and the one for #5 was definitely a bit short. So next little job will be removing the little nuts and replacing them with new ones, or make something that fits ๐Ÿ™‚

Mike Fleming, flies from Rangiora airfield, New Zealand

Hi Gert,
Thanks for seeing to my chocks yesterday. My Eindekker flew beautifully for an hour but the cold was getting to me. I am happy to have an aeroplane to fly again, all three of them were grounded for a while for various reasons. I will tackle the Luton Minor next as that just needs attention on one cylinder head gasket. I do enjoy flying the Luton.
I am very impressed with your web site and the organised way you are going about things. I love your radial engine. Did I tell you that I have a Rotec nine cylinder radial for a Spezio Tuholer that I am working on at home? I note that your house is made from straw bales too. That would be my ideal choice of building material as well but the council I believe does not allow that construction any more. Sad. Knock on my hangar next time you are at the airfield I tend to lock myself away so that I can get things done but would love to catch up with you again. I am glad that you have Evan Belworthy on side he and his father are a fount of knowledge. Alan is particularly good with magnetos and general ignition problems.
Regards, Mike.
