Title: Dufaux 4 in 1:32 scale
Post by: Des on September 07, 2015, 11:41:52 AM
I have decided to scratch build a model of the Dufaux 4 biplane from 1909, here is a short history of this aeroplane;

(https://lh3.googleusercontent.com/-9vP8RH-oias/VdO1DHL1L9I/AAAAAAAAShM/phJTrXd1idg/s1024-Ic42/dufaux%252520x%25252010.jpg)

Dufaux 4 - the ancestor of Swiss powered flight.[/b]

This machine was the fourth constructed by brothers Henri and Armand Dufaux from Geneva. The first was a 17 kg model helicopter, the second an unairworthy monster with eight wings, and the third crashed on its maiden flight.
It was only with the Dufaux 4 that Henri, a painter, and Armand, an engineer, achieved the success they had been striving for. On 28 August 1910, Armand Dufaux flew the length of Lake Geneva from St. Gingolph to Geneva in 58 minutes and 5 seconds. A masterly performance that won a prize of 5000 Swiss francs. The same year, they founded an aircraft factory. The improved Dufaux 5 was bought by a 17-year-old Ernest Failloubaz, at that time the youngest Swiss pilot. In autumn 1911, he demonstrated it to the Swiss Army, flying reconnaissance missions during a manoeuvre. Although the experiment ended with a crash landing, it still marked the start of Swiss military aviation.

Technical data.[/b]

Original                      Dufaux 4 biplane
Year of manufacture    Around 1909
Wingspan                   8.5m
Maximum speed          78 km/h
Power plant                8-cylinder ENV piston engine

I found and downloaded some good drawings of this aeroplane on the net, I then scaled these drawings to 1:32 scale using my drawing progam on my computer. I printed out several copies of each plan onto A3 paper using my inkjet printer (I'm glad I purchased a printer that not only does A4 but A3 as well)

(https://lh3.googleusercontent.com/-t9nsXau_3J0/VdO1Nfr9pJI/AAAAAAAAShk/Wr3JCiUR3vw/s800-Ic42/plans%252520x%2525202.jpg)

(https://lh3.googleusercontent.com/--sSLHCWWNUs/VdO1RTfEVcI/AAAAAAAAShs/vCpfr_1oW4k/s800-Ic42/plans%252520x%2525201.jpg)

As the engine for this model is quite complex I have decided to built it first. I started by making the bases for the cylinders, these where cut from 0.5mm styrene sheet with a 4.5mm hole punched into the centre, I also drilled 0.5mm holes into each corner to take some bolts. I cut short lengths of 4.5mm brass tube and CA'd them into the centre holes, the bases where then aligned into two banks of four.

(https://lh3.googleusercontent.com/--xbHo3Y_3So/VekIQZXXpoI/AAAAAAAAS3o/Ibe_XlkrwrE/s800-Ic42/dufaux%252520x%25252016.jpg)

(https://lh3.googleusercontent.com/-9wzIwUQsVww/VekIPG43L1I/AAAAAAAAS3g/kd2QtorHx7E/s800-Ic42/dufaux%252520x%25252017.jpg)

For the crank case I started with a length of good quality 16mm Aluminium solid rod. The first job was to turn this on my lathe down to 15mm. I then did quite a lot of filing and sanding to obtain the two flat surfaces for the cylinder bases to sit. I also cut from a sheet of aluminium the top centre section of the crank case, this was CA'd in place. I turned up another piece of aluminium to a size of 7mm, this was tapered toward the front and glued to the front of the crank case, I drilled a 1.2mm hole into the centre of this to take the prop shaft. The stregthening ribs are made from 0.8mm aluminium while the engine mounting flanges are made from 0.3mm aluminium. The rear of the crank case was filed to produce a mounting area for the magnetos. The entire assembly was rubbed down with 1000 wet and dry paper then buffed with 0000 steel wool.

(https://lh3.googleusercontent.com/-z_iaFfZF21c/VekIYsSizHI/AAAAAAAAS4o/UDpGdYNLtXA/s800-Ic42/dufaux%252520x%25252026.jpg)

(https://lh3.googleusercontent.com/-FXq7ly97_p8/VekIZ7ZHM0I/AAAAAAAAS4w/n7DDv8wEDzg/s800-Ic42/dufaux%252520x%25252027.jpg)

(https://lh3.googleusercontent.com/-8mVVlCp5hPM/VekM-M5pCQI/AAAAAAAAS5g/owzO4irt7Ng/s800-Ic42/dufaux%252520x%25252029.jpg)

I mounted the two banks of cylinder bases to the crank case, these are held in place with 5 minute epoxy, using this glue allowed me time to adjust the position of the bases and when set gives a very strong bond. The two banks are slightly off-set to each other, one set sits at the front edge of the crank case while the other set is slightly toward the rear. The cylinder bases were sprayed with Mr Metal Colour Stainless, when dry it was buffed to give a nive metallic sheen.

Yahooooo! Des is scratch-building again!!!! Now is the time to pay attention and learn some more tricks.

Never heard of the type Des so thanks for the background information. The engine is as usual wonderful - makes my efforts look positively amateurish. I can see the making of another wonderful model here.
Title: Re: Dufaux 4 in 1:32 scale
Post by: IanB on September 08, 2015, 02:45:57 AM
Bob, A4 is the standard size, close to "letter" size. A3 is twice the size of A4. (A5 is half the size) I'm sure there was logic applied somewhere....

those remind me of curtiss ailerons suspended in between the wings. neat looking plane des and your engine block is looking sweet.
Title: Re: Dufaux 4 in 1:32 scale
Post by: Des on September 09, 2015, 08:47:49 AM
Thanks Scott. You are quite correct about the ailerons, having just completed the Curtiss Hydroaeroplane the ailerons are very much the same. At that time there was a huge court battle going on between the Wright brothers and the rest of the aeronautical world regarding copyright for their wing warping. Inventors were coming up with all sorts of ideas to get around the copyright and this is one of those ideas, this was a very successful method.

yes you're right.the sad thing is Orville and Wilbur or so worried about anyone copying them that they lost initiative on new design and ended up getting passed up by everyone in the long run
Title: Re: Dufaux 4 in 1:32 scale
Post by: Des on September 13, 2015, 01:10:32 PM
I had some difficulties sourcing 3/16" (4.76mm) brass rod for the cylinders on my engine, I finally located some in South Australia so hence the time delay since the last post. In the mean time I made the top section of the fuselage frame, this was made from various sizes of Evergreen styrene strips, this will eventually be painted a wood colour.

Post by: Des on September 13, 2015, 01:14:39 PM
The brass rod finally turned up. I have started to cut the length of brass rod to 4.5mm lengths, I am doing this with a razor saw which does a fairly neat job, I tidy the ends up on my lathe. This photo shows the first 4 cylinders just sitting in position but bear in mind that there is a lot more work to be done to each cylinder. Each completed cylinder will be highly polished. In the photo the cylinders tops have not been cleaned up as they will need to be shaped, so plenty of file and sanding work ahead of me.

Des, your work is really unbelievable, but yet there it is.
I was just curious, other than it looks really great, why did you use aluminum for the block rather than styrene?
Again, just curious.

Mack
Title: Re: Dufaux 4 in 1:32 scale
Post by: Des on September 17, 2015, 08:07:50 AM
Thank you Mack for your kind comments. I use aluminium for the crank cases simply because I like working with metal, it polishes up very nice which makes it look lke the real thing, no painting required. It also adds a little weight to the model which helps to keep the model balanced. CA (super glue) bonds very well to aluminium so attaching accessories are no problem. At the moment I am working on the eight cylinders, these are being made from 3/16" brass rod and will require a lot of filing and sanding, all very time consuming but very rewarding. I have a small clock makers lathe which comes in very handy.

Post by: Des on November 08, 2015, 08:27:51 AM
Thanks Scott for your post.  The build has stalled for the time being due to various reasons. First off sourcing the correct size material has proven difficult but I am on top of that now, secondly life has been throwing me some issues lately which needed my concentrated attention, and thirdly my right shoulder has been giving me curry lately, I had a cortisone injection last week so hopefully this week it will kick in and give me some relief. Apart from all that, life is good  :) :)

Post by: Des on November 22, 2015, 02:41:57 PM
Sorry for such a lengthy time between updates but life has been getting in the way of my modeling.

I have added the eight cylinders to the crank case, also made and added the intake manifolds. The exhaust pipes were made from 1.2mm brass tube and RB Motion aluminium nuts, once fitted they were painted with Mr Metal Stainless and lightly polished. I also fitted the push rods and valve springs. Next up will be the water pipes (I'm waiting for copper tube to arrive) and spark plugs (waiting for them to arrive from RB Motion), the engine is now getting close to completion. Because the engine is made mostly of metal it is quite heavy.

I finally found time to finish the engine for this scratch build. I used as much real metal as possible to make this engine hence the slow progress. The spark plugs are from RB Motion which are turned from aluminium, a brilliant product, I added the ignition leads today. I also made and fitted all the water pipes which are made from various sizes of copper tube. Because the engine is metal I sprayed the entire engine with a few coats of full gloss clear, this will stop it tarnishing. There are still a few more smaller pipes to be added but these will go on when the radiators are fitted.

Des.

Des, sorry you're having to go through all this, I know it can be very emotionally draining.  I've been through it with both parents, they are gone now, but what I found most exhausting was all the decisions that had to be made and trying to make sure I was making the best decision possible.  Especially with deciding what to do with their things, things they acquired over a lifetime.  Now you're having to decide what to do with "things" but there are so many emotional ties to a great deal of them it can be extremely exhausting.

I wish you well, my friend.

Thanks guys for all your kind words regarding my father and the Dufaux 4 build.

I have been sitting at my model bench for the past three days going over the information I have for my scratch build Dufaux 4 but unfortunately I just don't have enough information to complete the project. I have written to the museum where an example is on display but I have had very little response from them, internet info is pretty sketchy and very basic so I sadly have to say that this project has now ended, at least I have a completed engine for another project.

   That's a real shame, Des, you must be somewhat frustrated by the lack of response you've received. Hopefully someone might be able to visit the location and get more info, which Museum?
   I hope this works out for the better, you put a lot of work into these Builds.

Thank you Thumbs Up and Lance for your suggestions. The museum is the Swiss Museum of Transport, I don't want to bother anyone by asking for photos of the display aircraft, in the past members have gone out of their way to photograph particular aircraft for me but it takes them a lot of time and effort and in most cases takes them out of their way. I will leave this scratch build and now call it defunct.

This is indeed sad news Des. You always choose builds that are really interesting because they are so esoteric - usually a type that I have never heard of and I suspect that many others have not done so either. I sit in anticipation that you might be able to finish it, but if not I will be in the front row for your next project.

Hello Des,
I hope you are doing well and that the morale holding good.

There was a project in Switzerland to crate a replica of a Dufaux 4N aircraft (if I'm right). The goal was to repeat the flight of Dufaux over the Lake Léman.

The team have a website
http://www.hepta.aero/faux/fr/index.html (http://www.hepta.aero/faux/fr/index.html)

If you tell me what you are looking for (drop me a PM), I will be glad to contact them (I live not far from Lausanne) to see if they are "open" to share some documentation and information.

Moreover this you can go to this website
http://ba.e-pics.ethz.ch/ (http://ba.e-pics.ethz.ch/) and put Dufaux in the "search" window there are some nice pictures that could maybe help you.

"Official Museum" are for the most in the German speaking part of Switzerland, and it could be, unfortunately, very difficult to obtain something if you don't speak german.
Cheers
