Hi guys (if there any gals here, howdy to you too).
Found this site a short while ago. I just turned 50, so I have now begun to do the things I wanted to do "later". I think I was hooked already when as a kid I first saw the Wallis autogiro in "You Only Live Twice".
I want to build a Gyrobee. I like the look of open, early ultralight plus I don't think I can afford a more expensive machine (at least the parts I have in stock tells me to build a Gyrobee).
I am by education a Mechanical Engineer (like a B.Sc.) and have been flying R/C planes for a looong time. I was even shortly a member of the Danish EAA chapter and attended a course in composites "the Rutan way".
I live on a small island called Bornholm. It lies in the Baltic Sea, belongs to Denmark but is much closer to Sweden. It's a perfect place to fly around in a small, ultralight gyroplane.
And I already have this:
Skywheels 23 ft. rotor blades with hub. Stored for 18 years, never been used. No damage. I just wish I had bought a 25 foot rotor, though.
Rotax 503 single carb engine, with intake silencer, 2x90 deg. muffler and aftermuffler. Spark plug holes still plugged, engine never started.
Propeller, 62 x 32 mahogany, old 1916 style (rounded leading edge, straight trailing edge).
Some instruments I bought at Oshkosh, altimeter, ASI and EGT.
I believe I can get the usual stuff in Denmark or Sweden like the aluminium tubes and bars, but the exact wheels and special items could be hard to find.
So I'll surely ask around a lot.
I have built a small home shop out in the back, where I have crammed some machine tools in:
Deckel FP2 universal tool mill with (almost) all the accessories there was made for it.
Weiler LZD220 lathe (small).
Boley 5LZ lathe (10" x 20"), which I am now restoring.
Work bench with drill.
Dillon (Henrob) oxyacetylene torch for fine welding.
Migatronic MIG/MAG 180 Amps welder.
Plus the usual collection of hand tools.
Not having much access to aircraft parts in Denmark, I plan on producing as much as possible myself out of 6061-T6 and whatever steel is neccessary. So I'll be a pest asking about where to get parts or if I could make things myself (because I have the lathe and mill). I am looking forward to building a composite tail ;-)
And now to have some fun!:plane:
Cheers
Erik
PS: In the mid-eighties I imported a Rotax 447 intending to build some kind of an ultralight aircraft.At some time I bought "Modern Rotorcraft Design" from Hollman (wanted to use it in a school project) and later discovered the BumbleBe. 1988 I went to the US, trying to meet Hollman and buy a set of drawings, but he brushed me off, which made me miss the start of the Oshkosh week:Cry: . But once there I met someone who had built a Bumblebee (With a Kawa 440). And I called the McCutchin brothers and ordered a set of 23' blades (I saw them on the AirCommand447). I discovered I had gotten the wrong gearbox, so a dealer made a swap, so I ended up with a 503 but with the right gearbox. Eventually I _had_ to stumble over the Gyrobee website, where I instantly downloaded the docs.
