I have a set of Grove alum landing gear taking up room in my shop. I would
take a couple of hundred bucks for it and you could cut it up as needed. If
you are interested, I can take measurements and some pictures to send you. I
think it would ship UPS with no problem.

Hey all,
For fun, I'm building an experimental high-mileage vehicle. It'll be a
motor powered recumbent trike type of thing with an aerodynamic fairing.
I'm trying to figure out a simple, low profile front suspension (two
steering wheels in front). The thing won't go faster than 50mpg so it
doesn't need to be great, just sturdy.
I got to thinking of a flat spring aluminum plate that would have some
spring in it, kind of like a Cessna gear and wondered if anyone knew
anything about how to get spring temper in a thick aluminum plate/bar?

| Subject: | steel tube fuselage tacked |
Update on latest progress. Finished tack welding my fuselage today. If curious,
it weighs 33 lbs. Hard to get real accurate weight comparison, at this point,
to the wood fuselage because some steel needs to be taken off and some steel
added.
Need to cut: top longeron where front door goes.
About 1 foot of Tail post. Kept on for ease of
keeping alignment.
Need to add: many tabs for attaching ply, instrument panel...
Finish weld will add weight.
No need for side ply with steel fuselage. Also, fuselage reinforcement of right
side for door adds weight.
How do you think this compares with the weight of the wood version?

hi douwe, mike weston here. if you go into eaa magazine archives and look at ed
lesher's "teal" you will see he used 7075 T-6 plate for gear legs. the dimensions
are shown in the three view drawing. this aluminum can be used as is for
monoleaf type springs.

Thanks Scott. Just remembered I still need to add the "v" back support behind both
seats and a diagonal at firewall.
Also question: on supp plans of wood fuselage it shows 7 7/8 rear instrument
panel width and 6 1/4 front panel width. Is this plenty wide enough for standard
instruments? And should I do the front width same as back if planning on instruments
up there too?

Paul, the deepest instruments are generally radios, Instruments that are
used for IFR conditions tend to be deeper than slip-skid balls and
pitot-static instruments. So the answer to your question depends on what
instruments and radios you want in the front, rear, or both panels. A
simple setup doesn't require anything deeper than what is called out in the
plans. Have fun with this, Ken

| Subject: | A modest proposal |
Hello all. I have an idea today and if it has been proposed already
please forgive me, but I was thinking about the US mail service
transcontinental airmail beacon route which was opened on September
08,1920. The route consisted of huge concrete arrows every 10mi with a
50 ft tower and a bright beacon light to assist airmail planes to
navigate in poor visibility. The completion of this route meant that
mail could cross the continent in from Crissy field in San Fran to
Hazelhurst field Long Island, in about 30 hours rather than 10 days by
pony express. In the 1940's the commerce department decommissioned the
beacons and the steel was used in the war effort but the concrete arrows
remain to this day. It occurred to me that Sept 2020 marks 100 years
since the air route opened and I thought that it would be a good excuse
to make a continental journey in a vintage type aircraft following the
arrows to commemorate the creation of the system. Perhaps a little early
to start the discussion but perhaps not. In any case as a Canadian it
would be pointless for me to try to get some interest and perhaps
financial backing for such an undertaking myself, but if some intrepid
young man to the south of me was to take up the torch I think it would
be very cool and an adventure of a lifetime to tag along in my own Piet.

Any interest? Comments?

i would also like to point out a mistake i made but fortunately caught and fixed
after this photo.
notice behind the aft seat, the diagonals along the top that tie the left and
right sides together should be going in the opposite direction of the diagonals
on the bottom. was easy to fix since they were just tack welded. just reverse
directioned the two top diagonals.
I failed to notice on the plans that the drawing of bottom of fuselage were
viewed from the bottom, and drawing of top of fuselage are viewed from above.
wood plans are identical with the exception of having 3 diagonals instead of 3.
thought it was worth pointing out , looked at those plans many hours and never
noticed.

Paul,
I happened to weigh my wood long fuselage with seats and floor plywood. It weighs
exactly 50 pounds. Once you get those installed you will have something to
compare. I see a lot of weight savings by not having the plywood on the sides.
2'x8' 1/8 ply weighs about 10 lbs times two sides. I plan on compensating for
that with more horsepower, diet and exercise.
Seats weren't finished in the picture but the parts were placed on top fir the
weighing. The are to be installed later.
Sorry about the picture size.

Kelly (and others), thanks. As it turned out, we were fine. Our home sits
on a rise just to the north of a golf course in northwest Longmont. We
stayed dry throughout but had a front row seat for much of the worst
flooding in the city.
The major waterway through Longmont, the St Vrain, jumped its banks and, in
effect, made a new river bed about a half mile to the north. The river was
a mile wide as it entered Longmont. It surged through and across a
neighborhood just west of the gold course that we overlook, completely
engulfing the golf course, and then exiting through yet another
neighborhood to the south of the golf course. Those neighborhoods have been
devastated. I suspect that many of the homes will be total losses. All of
them have serious E Coli contamination from the failure of all of the
upstream waste water treatment facilities and many septic systems.
Friday night during the midst of the flooding we had the windows open and
were surprised at a constant low throbbing roar. It was the water surging
across the golf course. While in a strange way it was nice to have
riverfront views, it was even nicer when the water was finally returned to
its regular channel. The Corp of Army Engineers and the City worked hard
at making that happen. Lots of roads and bridges have reopened. Many,
however, are simply gone. The only means currently for people living
between Longmont/Loveland and Estes Park (e.g., in Lyons, Pinewood Springs,
Glen Haven,Storm Mountain, etc.) to get to the outside world is by
helicopter. No roads are now functional in that area and may not be for
weeks or perhaps in some cases months.
Fortunately, the flood control systems at the Longmont airport worked as
designed, helped no doubt by the fact that the St Vrain chose to shift its
channel to the north. Had it shifted the channel to the south, the flood
controls at the airport would have been overwhelmed. So by a twist of fate,
my Piet project and Pacer stayed dry and safe.
Again we were mostly unaffected except for the many detours and traffic
delays, which seem pretty trivial compared to what many others have been
facing.
Again thanks, Ken

My dad sent me a link about the big concrete arrows not too long ago and I had
the same idea.
However, most of the arrows are gone from civilization... there's still a bunch
of them in the boon docks, mostly out west from what I can gather. I was unable
to really tell if it's documented well enough that the route could be flown
anyway. Of course, much of it transverses airspace that I can't go without
a transponder or radio...
Anyway, I can fix, I can build, I can fly... but organization is NO WHERE to be
found in anything about me... I got nothing. I would be interested in joining
some sort of effort to fly legs, whatever. Help identify parts near where
I live, or something.
As soon as I learned about these things, I thought it would be so cool to fly that
route. Sort of a route 66 for old airplanes sort of thing. Interested to
see if there's much other interest.
