Craig Saunders, President, LUNAR #890, NAR #76743
Over the last couple of months, I have encountered a number of
discussions and incidents relating to rocketry vendors. These
include:
• At another rocketry club, there was an argument about
how many on-site vendors at a launch were too many.
• Yet another rocketeer got burned by a rocketry vendor
whose customer service is so bad that folks have filed
fraud charges against him. Stories abound about how it
can take him years to ship orders.
• I was asked if it’s more important to be loyal to vendors
who come to launches and order on-line from them or
to go to a local hobby shop.
• Recently I ordered from 3 rocketry vendors and 2 nonrocketry vendors at about the same time. The rocketry
vendors lost my orders and I had to call to get them
shipped. (One still hasn’t shown.) The 2 orders from
non-rocketry vendors showed up on-time and without
any problems.
Now I know that most rocketry vendors are one-man businesses
and many of them have full-time jobs that really pay the bills.
So I appreciate that our hobby isn’t large enough to support
many vendors. And I’ve gotten to know many vendors and all
of them have the best of intentions. And most of them are really
nice guys.
So this isn’t a personal thing in any way. But why do we as
rocketeers put up with such crappy customer service? At a
recent lunch with rocketeers, when the conversation turned to
rocketry vendors, there were many horror stories. Yet most
rocketeers continued using the same vendors.
The only way that we will get better service from rocketry
vendors is if we stop using the ones who give us crappy service
and shop at the ones who do.
Here’s what I have in mind regarding rocketry vendors:
• HPR launches must have vendors to be successful. . In
today’s regulatory environment, on-site availability of
HPR motors and reloads are the only way for many
folks to fly. So when I’m at a launch, I shop (at least
look at) all the vendors. I’ll be sure to buy from the
ones who provide good service and not buy from the
ones who don’t.
• Okay, so that doesn’t address how many vendors are
too many at a launch. Frankly, from any perspective
other than the vendors, there isn’t any such thing as too
many vendors. None of the vendors stock everything,
so more vendors means more selection. And
Volume 15, Number 3
May 2008
competition usually improves both customer service
and prices.
• Yes, that’s tough on vendors and some of them will go
out of business. But it’s usually the ones with worse
service and higher prices. And if they go out of
business, that will leave more business for the ones
with better service and lower prices. Which is good for
the rest of us.
• Local hobby stores are a necessity for our hobby to
grow. This is where folks new to our hobby go to get
their first kit or more motors to fly the rocket that they
built at one of our outreach activities. And it’s where
you can get glue or paint or balsa or whatever you need
to finish your rocket so it can fly at the launch the next
day. So I always buy my CA and epoxy and paint at
local hobby stores. And when I’m there, I often pick
up other stuff that’s interesting. And it’s where I
recommend newbies buy their first rocket.
• Before buying from an on-line vendor, I check with
other rocketeers before ordering. While I know that
others’ bad experiences may be an exception, I’m not
really up to proving the rule.
Thanks for letting me bend your ear about this. Now… “Let’s
fly rockets!”

Launch Site Search Report
We’re working hard on finding LUNAR a new home for LPR
launches in the Bay Area.
Most of our energy right now is being spent with NASA Ames.
Dave Raimondi, with a little help from me, is currently working
out details of how to conduct the launches and co-ordinate with
the Control Tower and NASA officials. If things continue to go
as they have recently, we may start having monthly launches
there in July or August. Currently, we’re talking about rockets
with A-G motors and a ceiling of 1000’.
The July LUNAR launch will be at Quail Run Park in San
Ramon on July 19th. We’ll be able to fly A-C rockets to 900’.
I’m still working on details with the Park District and Fire
Department, but I do have the permit. More details will be on
the website and on the email lists in a couple of weeks.
We’re still working through the school district bureaucracy to
fly at Monte Vista High School in Danville. (The site should
allow A-G rockets to 1500’.) At this point, I’m trying to see if
Page 2
LUNAR’clips 2008
Volume 15, Number 3
May 2008
we can fly there in August. But I haven’t gotten a commitment
from the school district yet.
•
I’ve spoken to Patterson Parks Department about conducting
another launch in September at their Sports Complex. But
haven’t heard yet if they’re interested.
•
•
Jack continues to work with Alameda County and we are still
working in Livermore and with LARPD.
I want to thank Bill Woodruff on his work on the Alameda NAS.
This is a good opportunity but represents a fair amount of effort
to get approved. So we’re going to work on the other candidates
before pursuing this one.
Oh, and I continue to get requests from folks interested in flying
in the Sacramento and Monterey Bay areas. If someone wants to
be a hero by finding a local launch site in either area, I’ll be
happy to be your sidekick. ☺

LUNAR Board Meeting Report
Dave Cummings, Secretary, LUNAR #450, NAR #78453
Minutes from the April 24, 2008 Board
of Director’s Meeting
April’s BoD’s meeting conducted a full agenda with all board
members attending. Present also was one LUNAR member just
interested in the club’s business. Anyone is welcome to come to
the BoD meetings to sit in on and listen and participate in the
club’s business.
The first topic for the evening was equipment:
• The new trailer is now at Bill Orvis’ place. He now has
both trailers there. Bill is working on the new trailer
getting it set up for use sometime this summer. The old
trailer will be sold off for $750. This will make the
total effective cost of the new trailer just over $1000.
• Craig Saunders brought in the prototype high power
pad. Each new pad will cost about $120. There are
still some details that need to be worked out before the
prototype will be ready.
• Some discussions for an equipment cleaning party were
talked about but no definite plans on that for now.
Club’s financial status:
• Bank account at end of 2007 about $3100 and currently
at about $2300.
Some recent money making events was the auction at
SR that brought in $309 and donations for the trailer
was $357. Thanks to everyone who donated.
Membership drive starts soon.
There’s plan for Snow Ranch T-shirts sells for next SR
season which is a good fund raiser.
LUNAR business cards were suggested as a means of promoting
the club but the board didn’t approve the expense of any
business cards at this time.
Maker Faire is coming up soon and preparations are under way.
500 kits will be donated by Estes and motors will be provided
for free. A $2 donation is suggested per rocket to help cover
other club expenses. Volunteers are needed.
The NAR Newsletter trophy and box will need to be returned in
the near future. The club needs to determine what to put in the
box but nothing definite was decided. Any suggestions would
be welcomed.
The on-going discussions for a new launch site and up-coming
launches were talked about. Briefly: July launch in San
Ramon, a couple of launches planned in Patterson. Watch for
more details on those launches. No progress was made in the
Livermore area. Talks are on-going with NASA Ames in the
South Bay area.
Club meeting agendas are scheduled with the following topics:
• May 22: Dave Raimondi, Launch Safety Risk Analysis
• July 24: Dave Cummings, CFD/Aerodynamic
Software
• September 25: Build Session
• November 20: Eric Norris, NASA Ambassador
• January 22: Elections and Gene Engelgau, Packing
Parachutes.
With the plethora of topics and speakers, it was suggested that
having a Rocket Day during the Fall season. This could be on a
Saturday and there could be a couple or more sessions during
the day on rocket related subjects. Stay tuned if more develops
on this.
LUNAR Club Meeting Report
Dave Cummings, Secretary, LUNAR #450, NAR #78453
Minutes From May 22 Club Meeting
The main topic of the meeting was on launch safety analysis. A
risk assessment of model rocket launches was put together by
the BayNar club back in 2004 for NASA Ames. It was updated
by the LUNAR club and David Raimondi was going to present
the assessment to the club for review and to critique it. Dave
Page 3
LUNAR’clips 2008
was not able to attend the meeting so Craig Saunders led the
review of the risk assessment.
There was a total of 32 items on the list stating a potential
failure, potential cause, and a control method along with the
severity, probability of occurrence, and a probability of
detection. The club members reviewed each item and gave
inputs to the improvement of the safety risk analysis. This risk
assessment will be presented to NASA Ames as our club works
with them to obtain the privilege to hold launches there in the
future. Dave Raimondi has done a lot of work with NASA to
get a launch site there and there may be a dry run launch there in
the next month or so. Thanks Dave for all your work.
Other club discussions for the evening were on the Maker Faire.
The Maker Faire was a big success and a good source of revenue
for the club. We are looking forward to next year there. The
new trailer is now loaded with all the club equipment and the old
trailer is being sold to Stanford. There will be a cleaning party
on June 7 to clean up the club’s launch equipment. Next launch
is in San Ramon on July 19.
Trailer Cleaning Party
William Orvis, LUNAR #309
I want to thank everyone who came by my house for the
LUNAR Equipment cleanup day, June 7th. In about 2 hours, we
did what would have taken me the whole weekend to do alone.
Unfortunately, as the LUNAR trailer was done, Julie let me
know that there were some other things that needed doing, so I
didn't get out of any work, I just did different work.
Richard Hagen's magic cleanup solution made the launch rods
and rails sparkle. It is kind of amazing as they have not been
silver for a long time. Screws are tightened, launch clips are
replaced, and the new trailer has a shine to it.

Thanks again to all who helped: Bill Orvis, Richard Hagen,
Daryl Paris (wasn't there but built the cleaning trough
contraption), Jack Hagerty, Craig Saunders, Tony & Crystal
Cooper , Steve Kendall, Charlie Wittman, Steve Kurlinski, Paul
Pittenger, James Marino, and Eric Kleinschmidt.
Note From the Editor
Cliff Sojourner, LUNAR #1212, NAR #82864
LUNAR’clips won the 2007 “North American Rockwell
Trophy,” (also called the LAC Award ) given annually to the
NAR section with best newsletter. LUNAR Past President Jack
Hagerty brought the trophy and secret box back from 2007
NARAM (NAR Annual Meeting). All year, the LAC trophy
has been proudly displayed on a nice teak cabinet we have, next
to our teak China cabinet. The trophy is impressively sized and
has lots of shiny fancy stuff and is topped by a silver cup with a
rocket poking out. It impresses every visitor to our house, even
my mother-in-law.
It’s been fun, but NARAM 2008 is coming soon, so now it is
time to pack up the trophy and secret box, and send it back to
NARAM with Jack Hagerty. First, I took the plate to get it
engraved with “LUNAR 2007”. Second, after a year to think
seriously about it, I’ve decided what to put in the secret box. No
I won’t say here, but LUNAR members can ask me any time.
Last, we think the best contribution LUNAR could make is a
good carrying case to protect the trophy and secret box during
travel. This is a bit like Frodo returning the Ring to Mount
Doom, or maybe more like Indiana Jones returning the crystal
skull to the alien chamber. I will buy a sturdy travel case with
wheels, so Jack and future transporters can take it through the
airport without getting suddenly possessed or accidentally
tearing the fabric of space-time.
As always, I feel good to finish this issue and send it out. Now,
to get through
the pile of
mail that has
accumulated
and send in
my
membership
renewal! I am
looking
forward to
another great
year of flying
with LUNAR.

LUNAR at 2008 Maker Faire
LUNAR exhibited at Maker Faire (May 3rd and 4th) and
conducted a Make-It/Take-It/Fly-It activity with the kit building
indoors and the launching outdoors.
LUNAR again shared the Rocket Room with TRA prefecture
AeroPac (http://www.aeropac.org). Elsewhere at Maker Faire
were the Mavericks rocket group
(http://www.rocketmavericks.com) and the X Prize folks.
Our exhibit went well – the rocket room was always full with
builders and folks learning about model rocketry.
Because of Estes’ contribution of kits, we were able to keep the
participant cost at $5 for the kit & glue & Kevlar & streamer,
one A rocket motor, and launch.
AeroPac was able to conduct static firing of HPR motors for
first time.
This year was the most successful LUNAR at Maker Faire.
Fairegoers built 527 kits, which is 60% more than last year.
Thanks to Estes for contributing the kits.
We flew close to 85% of the kits. Last year, only about 66%
flew. This year we had the launch area all day, so folks never
had to wait long to fly. This was a major improvement over
fixed launching times, as last year.
We relied on our many great volunteers from LUNAR and
AeroPac. Not in any order, and sorry if I didn’t list your name
here: Craig Saunders, Jay Bryon, Stu Cobb, Susie Cobb,
Richard Hagen, Dave Risher, William Kellerman, George
Thym, Emily Thym, Charlie Whittman & Jason Chambers, Cliff

Thank you all so much for creating the tremendous success that
was the Rocket Room!

With our current launch site problems, Maker Faire 2008 was a
great opportunity for outreach effort – we got to talk to lots of
people (80,000+ faire attendees), show off our rockets and help
folks build and fly their own. We have already had 3 people
contact us about when we’re launching.

Tribute To The Rat Fink
William Orvis, LUNAR #309
The Rat Fink
In the 60s Ed “Big Daddy” Roth was known for his elaborate
chopped cars. He made some of the most unique hot rods that
had ever been seen. His cars brought people from miles around
to car shows to see what Big Daddy had cooked up this time.
Rat Fink. They
drivers generally
featured bulging,
bloodshot eyes,
toothy grins, and
muscles poking
out all over. The
cars always had a
huge melty
looking engine
and a gear shift
knob that stood
as tall as the
driver.
One of the Rat Fink models.
As a kid, I built Rat Fink models, sometimes modifying them
to suit my own needs. For example, the Football Fink had my
dad’s college numbers and colors, which pleased him to no
end. And, while I have not made a Rat Fink model in many
years, they have all held a special place in my memory. So,
this year, I put my imagination to work and created the
Tribute to the Rat Fink rocket.
A Rat Fink chopped car. Creating wonders with fiberglass.
Big Daddy’s trademark was the Rat Fink, a stylized green rat
with a toothy smile, big ears, and a bright red R.F. muscle
shirt. Every kid knew who the Rat Fink was.

Designing the Tribute to the Rat Fink
Rocket
In the 60s Revell took some of Big Daddy’s designs and made a
series of Rat Fink models. These models featured an elaborately
chopped car being driven by a demonic looking guy or by the
To fit with the Rat Fink tradition, the Tribute to the Rat Fink
rocket needed to be very car like. It had to have an internal
combustion engine, a steering wheel and a gear shift knob. It’s
Page 6
LUNAR’clips 2008
Volume 15, Number 3

not clear what you would shift with the knob or what the engine
was for but they must be there. It also needed to have a cockpit
near the back for the driver.
To build this rocket, I used an 18 inch piece of BT-60 tubing
with a 24mm engine mount in one end. The engine mount
reached 4 inches in from the back of the rocket and had no
engine block so that I could use different sized engines (I wasn’t
sure what the final weight would be so I didn’t know what
engine to build for).
At 5 inches in from the back, I added a bulkhead with a BT-20
sized hole in it. The hole was not in the center but was offset as
far as possible to one side of the rocket. A second bulkhead was
placed at 12 inches from the back and a piece of BT-20 tubing
was glued in place between the two bulkheads. This created two
chambers, one in front of the engine mount and one near the
nose, linked by the BT-20 tube. This arrangement allowed me to
create a cockpit in the middle of the rocket and still have the
ejection charge pressurization delivered to the front chamber
where the parachute is stowed.
A view down into the parachute stowage chamber showing the forward bulkhead
and the BT-20 tube.
The cockpit was cut into the side of the tube just in front of the
fin location. Bits of tubing were used to create a chair back and
the instrument panel. After the rocket was painted, a piece of
plastic

the center of the rocket.
The fins were made from 3/32 inch aircraft plywood. Plywood
was needed because of the elaborate warp drive that would sit
on the vertical fin. Balsa wouldn’t be strong enough to hold the
drive. Each of the fins has a tube at the end (actually a piece of
copperhead storage tube). The tiny nosecones on the end of
these fin tubes were made from balsa.
The vertical stabilizer has a balsa cross fin and the warp drive
engine. The warp drive engine was made from the seal of an Old
Spice deodorant stick and two pieces of BT-5 tubing. The
junction between the tubes and the seal were smoothed with
automotive body putty and Bondo glazing.
The warp drive engine on the vertical stabilizer.
The 12 cylinder internal combustion engine (I don’t know what
it’s for but Rat Fink models must have an engine) and the pipes
are all made from Sculpty clay. Sculpty clay is like regular
modeling clay but if you cook it for 15 min at 150 Degrees, it
gets hard. For things like the exhaust pipes, you can harden
them using a heat gun (used for shrink tube) while they are still
attached
to the
body tube.
An Old Spice
lid formed
the front of
the warp
drive and the
small split
piece of wire
loom was
used to cast

disposable camera and the windshield of the cockpit is a piece
of packing for Kiwi fruit.
The right side of the rocket showing the 12 cylinder engine with a blue blower at
the front.
The turbo charger on the front of the engine is a piece of an old
speaker (left over from building the Bull Horn). The cylinders
were made using a short split piece of wire loom. Wire loom is
corrugated flexible plastic tubing used in cars to protect the
electric wires. It gets its flexibility from the corrugations. By
taking a piece of wire loom and splitting it down one side, I have
a mold for the cylinders. Stuff the mold with Sculpty clay, open
the mold along the split side, and you have a melted looking
cylinder.
The Rat Fink in the cockpit. The steering wheel is made from parts of a
disposable camera and the windshield is a piece of a Kiwi fruit packing case.
The decals on the rocket were made by jet ink printing. The
inside of the warp drive was printed on a clear label while the
Rat Fink picture and name were printed on photo paper.

and then glued to the bottom of the rocket.

beads. One bead was ground flat on one side so it could be

lose his ears if I kick it too hard. Hopefully, it will hold together
when it is launched, because with rockets, if it doesn’t fly it
doesn’t count.
Flying the Tribute to the Rat Fink
The Tribute to the Rat Fink was flown at the last LUNAR
launch at Robertson Park. Kind of a tribute to the park as well as
to the Rat Fink.
The grid on the inside of the warp drive was printed on a clear, adhesive label.
The Rat Fink decal was printed on photo paper and glued on the side of the fin.
Will It Fly?
This is a very odd shaped model with masses in inappropriate
places for rocket stability. I modeled it in Rocksim using blocks
for the Rat Fink and the internal combustion engine, and mass
points to get the CG and the total mass to agree with the finished
rocket. Rocksim indicates it is overstable. However, Rocksim
cannot reliably model things like the warp drive. It will
definitely be a heads-up flight just in case Rocksim is wrong.
The Tribute to the Rat Fink on the pad ready to go.
I loaded up the Tribute to the Rat Fink with a
D12-3 and placed it on the pad. I got a lot of
interesting comments when I started loading it
up. Such as, “Will that thing fly?” and, “You
aren’t really going to launch that are you?” I
kept repeating to everyone that, “If it doesn’t
fly it doesn’t count.”
The Rocksim layout of the Tribute to the Rat Fink. It shows a total mass of 380
gm or about 14 oz without engines.
The simulation indicates it should reach 130 feet on a D12-3
engine, which is more than high enough for a model of this type.
I could use a bigger engine, but I am afraid the Rat Fink might

he didn’t lose his ears. I recovered all the pieces so with a little
glue and paint, it will be good as new. In retrospect, an E18 or
F20 sized engine might have been a better choice to get the
Tribute to the Rat Fink moving and stable. I still believe it will
fly stable so maybe this winter at Snow Ranch it will fly (or not)
again.
The Tribute to the Rat Fink made it into the air but wasn’t going fast enough to
be stable.
OK, I should have kicked it a little harder. The launch went fine
but the D12 just didn’t get it going fast enough to be stable. It
arced over and flopped on the ground, and then ejected the
parachute.

Surprisingly, the Tribute to the Rat Fink didn’t sustain that much
damage. The front of the tube got a little bent, the pipes tore off,

Who We Are...
LUNAR is the Livermore Unit of the National
Association of Rocketry, Section #534
LUNAR is located in Livermore, California, about fifty miles
southeast of San Francisco. We are organized to supply a safe,
educational and legal means of furthering the hobby of model
and high-powered rocketry in northern California, to aid and
encourage the development of all club members’ knowledge and
expertise in the area of rocketry, to promote youth education and
community involvement, and to engage in scientific, educational
and related activities. LUNAR is open to rocketry hobbyists of
all ages to further the sport and science of hobby rocketry within
the NAR (National Association of Rocketry) and Tripoli safety
codes. These codes have allowed hundreds of millions of model
rocket launches by hobbyists since the late 1950s without
serious injuries.
LUNAR also supports assorted rocketry activities of community
youth groups. We have hosted launches (and in some case
building sessions) for the Boy Scouts, Girl Scouts, 4H, YMCA
Adventure Guides, the GATE program, and LARPD Science
Camp.
Launches
Section launches are usually held from 9:00 a.m. to 1:00 p.m. on
the third Saturday of the month. Generally these are sport
launches, although we occasionally hold sanctioned contest
launches for points in the NAR national contest standings,
theme launches where we focus on a particular class of rocket,
and night launches.
LUNAR’s Snow Ranch launch site accommodates all rockets
from 1/4-A to M motors, with a 15,000 foot maximum altitude.
The LUNAR Board requests notification of L and M flights a
week before the launch date. Contact the LUNAR Members At
Large directly, or post a message on [email protected].
The LUNAR Hotline - (925) 443-8705
The Hotline is available to provide up-to-date event information.
It’s a good idea to call our Hotline to verify the date of the next
launch or meeting.
On launch days, the Hotline recording is updated by 7:00 AM to
reflect the Go/No-Go status of the launch. On launch days with
questionable weather, it is especially important to call the
Hotline to get the latest information. You can also leave
messages on the Hotline.
Meetings
Section meetings are held bi-monthly. These meetings cover
general section business, and typically include presentations by
club members or other experts on some aspect of the hobby,
ranging from simple building tips to advanced science and
engineering principles. Officers’ meetings are held bi-monthly,
alternate months from the section meetings, and typically
concern administrative details.
The LUNAR annual meeting is held during the first quarter of
the calendar year at a time and place announced to the
membership. At this meeting, officers are elected and other
club business is conducted.
World Wide Web site!
LUNAR maintains a Web site at http://www.lunar.org

example, you’ll find our latest launch and meeting calendar,
directions to our launch site, a gallery of photos from past

newsletter), our section bylaws, pointers to member rocket
