MISSING 160 h.p. GNOME
As of the date of this notice, 22 Feb 2006, a very rare GNOME ROTARY ENGINE (crankcase S/N B11559, cam housing S/N 55015N, cheek plate S/N 11370) has been missing from the Rhinebeck Aerodrome Museum for nearly one month. It seems unlikely it was stolen as there was no forced entry into the locked carriage house where it was stored. To arrange for its return or to provide information leading to its recovery please contact WW1 AERO.
----------------------------

Let's hope it is recovered. WW1 AERO may be contacted about the engine by calling Leo Opdycke at (845) 473-3679 or by contacting me at cfg@carrollgray.com

Thank you and we appreciate any asistance. Now keep on building those cool tri-planes!

Well gents..on the subject of making these brackets, shock boxes, etc...
I simply used a hack-saw,..with flat AND round blades, file, and a torch. Add a few gallons of sweat and presto!...
No secret, no gimmick.
Sometimes you end up spending more time trying to find an easy way to do something when you could have it all done just by getting in and doing it.
Sometimes..its just not easy.

....getting one line of activity going in parallel with another may get you where you want to go quicker. and if it brings some of us into more frequent contact with each other as a result, there is an added benefit.

[vongrube]

Agreed..
There is always more than one way to do something...sometimes better, sometimes not.
I know there are times that one definitely needs a machinest, but most items on this aircraft do not. Most of us do not have access to a CNC machine, laser cutter, etc. My point was try not to let that bog you down on this project. about 99.9% of this aircraft can be built with hand tools, and a healthy understanding of aircraft building techniques ; thats where this site comes in real handy, and is appreciated I'm sure.
One can easily run the cost of this project sky high if you are having others do your work for you. Now..if money is no object..well..have a blast then! But most of us can't afford a $100,000 aircraft..maybe thats why we are building this plane for ourselves.
The post that perked me up was the one on the cost of ferrules.

1) $9.56 per ferrule with .063" wire (x 100)

2) $9.61 per ferrule with .080" wire (x 100)

3) $9.59 per ferrule with .071" wire (x 100)

Are you kidding me?

Could you share with us how you achieved certain problem tasks during your fuselage build, e.g. flanged control surface hinges,

Thanks

i totally agree with the reaction to the eye-popping ferrule prices....

today, Fritz Kempf and I used a Delta Planer to whack off that critical 1/8" off the webbed up spar ladders. What a relief to have that done- we were able to run through 2 at once, as there as a biting cold wind going on here in Connecticut. Anyway, now we can focus on the internal hardware for the spars prior to boxing them in.

Jim,
Is that planer a hand-held unit or a floor unit?

[vongrube]

Dogtail,
Well, I actually used extruded rectangular 4130 steel for the hinges. These were simply cut in half lengthwise, and then bent over the sleeves and welded. Nothing to it. There is no reason to go through all the effort on these that the plans show. Most of the triplanes and aerobatic aircraft aircraft I have seen simply have a flat steel belt wrapped around a sleeve. Most other homebuilts have a piano hinge. Argghh!
It works..and is a strong hinge.

[Jeff Brooks]

that was the price a spring manufacturer quoted me!!! and after being turned down by 3 other spring makers, I know that is expensive ... but it was the only offer that seemed to materialize. now since then people on this site have offered the ferrules from anywhere between $1.00 to $2.00 a ferrule. just waiting on a followup!

[Jim Bruton]

VonGrube, it was a tabletop unit- and i recommend using this method!
