Subject: [Scaleroc] CAD Model of D-Region Tomahawk



The D-Region Tomahawk has been one of my favorite scale models. It is
a simple single stage vehicle, but it can be modeled with full detail
including all external fasteners. The vehicle also flies extremely well.

As a fun exercise, I've created a CAD model of the full-scale vehicle
based on the dimensions and color information in the article by Howard
Kuhn. I've uploaded the CAD model and related information to a new
folder in the ScaleRoc "Files" area. Two CAD formats (IGES and STEP)
have been uploaded. I did not upload the native SolidWorks format due
to file size concerns. If you would like the SolidWorks files, go to
http://sites.
<http://sites.google.com/site/chrisflaniganrocketry/Home/scale-models-and-da
ta.> google.com/site/chrisflaniganrocketry/Home/scale-models-and-data.

I've also uploaded a few .jpg files to illustrate the CAD model.

There were a few issues that were not fully defined or had
inconsistent dimensions in the HRK data. If anyone has any comments
or suggestions for the CAD model, please let me know.

Very nice Chris!  I did not see the SWX files at the link

http://sites.google.com/site/chrisflaniganrocketry/Home/scale-models-
and-data

I d/l the step file and opened it in SWX with no problems.

I believe those 100 deg screws are a special aerospace spec--I posted
a link to SPS Technologies and some of their brochures here
somewhere...

nice job!

Hmmm -- you're right -- the .zip file with the SolidWorks files has disappeared.
I just tried to reload the file (~9.5 MB).  The file appeared momentarily, but
then it disappeared again.

I might be bumping into a file size limit with Google Sites.  To get around
this, I've divided the SolidWorks files into two .zip files:

1) D-Region_SolidWorks_Assemblies.zip
2) D-Region_SolidWorks_Parts.zip.

So far, these files have remained visible.  You'll need to download and extract
both files to have a complete SolidWorks model.  Please give it a go.

I'm not sure. It is funny though, because to me at least, in my repost it is

Mine is an html message though and not Rich Text or Plain Text. (My Outlook

Hopefully selecting html does not mess other people up too much because if

I judged the r and d project- its a great system! very effective, and
remarkable that no marking or damage at all from the "blast" on the
model was evident. I wonder if  light duty compression springs or a
pieces of silicone fuel line tubing could be used to make flexible flame
   tubes. Anyone tried that?

DGH

Thanks, Jim...  BTW, for those who have read the article, Jim is the one who
told me that PVC doesn't show up in x-rays.  :)
 
There was some damage to the Saturn I model at NARAM-50, but that was due to the
fact that the scale nozzles hang down below the base of the motors and got hit
with motor exhaust as it was deflected off the spider.
 
I actually have a lighter weight "staging spider" in the early planning stages--
both a gap-staged and an electronic version.  I've been pondering that for a
couple years.  One day it may actually turn into an actual sport/test model. 
Perhaps an R&D entry at some future NARAM (definitely not this year).

Josh & Jim,

Hmm . . .Has anyone actually "put that to the test" with Airport Security
yet ? ( Not one of you guys ! )

If that is the case, it would be possible to fashion a "Dagger" from
heavy-walled PVC . . .Schedule 80, for example,  and walk it right on to an 
airplane
undetected . . .

Cross post of a message in the Space Modelers Yahoogroup, which seems ot
explain things pretty well. Whatever you were used to with Krylon before, it's
all
useless now, you have to re-learn or perhaps some other paint(s) will be
better for various uses.

- George Gassaway


-------------- "Re: Paint Emergency!!!!!!"

  It's no wonder you are having trouble. To begin with, Krylon is no
longer the Krylon you're used to. This is due to the EPA meddling in
the product. I spent the last two weeks wasting money and trying to
solve a wrinkling/lifting problem (very similar to your reptile skin
appearance), including at least seven calls to Krylon. Desperation was
setting in since I was modifying a large model I built two years ago
for a land developer. Used Krylon at that time and had no problem and
went into this project using exactly the same Krylon paint so that
everything would be compatible. I thought. Boy, was I wrong!

Without making this story way too long, here it is in a nutshell. Up
until a year ago, the Krylon that we've all been used to was an
acrylic lacquer. Dries in 12 minutes and can be recoated without any
worry relative to the previous coat reacting. Unfortunately, the EPA
in their wisdom came up with regulations that resulted in Krylon
reformulating their old, reliable acrylic lacquer into an oil-based
enamel. Not just an ordinary enamel but an oil-based enamel. This has
several very interesting and very bad results where the modelbuilder
is concerned.

You now have a window of application, followed by an extended drying
period before it can be resprayed. The instructions on the back of
the can are very specific and MUST be followed to the letter. To begin
with, spray a light coat, wait five minutes and spray another light
coat. Repeat the process until you have the desired coverage. Keep in
mind that all spraying MUST be completed within one hour or the
underlying coats will wrinkle and lift. Not MAY but WILL. After that
one hour time period, you MUST wait a minimum of 24 hours before
applying another color coat or the previous coats that you thought
were dry will...you guessed it....wrinkle and lift. Do be aware that
24 hours in the MINIMUM waiting period. Depending on how many previous
coats you applied in the one hour time frame, you may have to wait
more than 24 hours to apply additional coats.

Although the instructions don't indicate the need for a base coat,
this stuff is so weird that I would definitely recommend a primer
base. However, even the primer is an oil-based enamel with the same
window of application and drying time. Be that as it may, be sure to
used the Krylon primer so that everything is compatible.

Finally, because you're dealing with an oil-based enamel, plan on an
extended painting session and multiple coats in order to prevent runs.
Because it doesn't have the 'tooth' or grab of acrylic lacquer,
applying enough paint to attain an opaque coat...especially where
white is concerned... white is concerned...<wbr>is guaranteed to result in

Oh, one last comment. According to Krylon, changing the formula from
an acrylic lacquer to an oil-based enamel made the product more user
friendly for the average consumer. I don't know about the average
consumer, but it did just the opposite where the modelbuilder is
concerned.

By the way, if you're still longing for the old Krylon acrylic
lacquer, it can still be found. As an industrial paint. Order it from
industrial suppliers in six-can quantities and use it over Dupi-Color
Gray Primer and Filler that, as far as I know, can only be found in
NAPA Auto Supply stores.

Don't get the idea that you can find another brand of spray paint that
will do the same job with a shorter wait time. ALL of them have
suffered at the hands of the EPA. The window of application ranges
from one to four hours and the wait time to recoat can be as long as
two to seven DAYS. You can also forget picking up pure lacquer
automotive paint that used to made by DuPont and available from
automotive paint stores. DuPont doesn't make it any more. Thank the
EPA for that as well.

Hope some of this helps.

Back when the change was first noticed, I think in a post last spring
by RocketDoctor on YORF, a bunch of us loaded up on old Krylon.   I
mainly got white and black.  So I've got maybe a years worth.

I picked up a can of the new white and used it on a couple of rockets
as an experiment.
It covers MUCH better than the old, and seems to level out just as
well. The pigment is brighter, too. The main problem is the smell.  It
stays for WEEKS.

By the way, the problem is not so much the Federal EPA, as it is
California and a couple of other states who have the strictest limits
on Volatile Organic Compounds (VOCs)

All,

I'm looking into the feasibility of building a 1/48th scale static
model of a Saturn V. The first hurdle is finding tubing for the first 2
stages. EMA used to make 8.25" dia tubing, but doesn't any longer. It
doesn't have to fly so weight isn't an issue, but strength is. Since
the combined stages will be about 5.5' high, plastic would be a
preferred material.

Anyone know if such tubing can be found?

Thanks for any direction/suggestions.

John Pursley and James Duffy have used very thin (1/64") plywood to make their
own custom-diameter tubes, John for a Mercury-Redstone and James for a Little
Joe. It sounds odd at first, but they turned out beautifully, and the technique
apparently isn't as difficult as it might seem at first. John's Merc is 1/12
scale, if I remember correctly, and it stands roughly 5 foot high (and probably
a 5" or so diameter), so it's in the same ballpark that you're talking about.

All,

I'm looking into the feasibility of building a 1/48th scale static
model of a Saturn V. The first hurdle is finding tubing for the first 2
stages. EMA used to make 8.25" dia tubing, but doesn't any longer. It
doesn't have to fly so weight isn't an issue, but strength is. Since
the combined stages will be about 5.5' high, plastic would be a
preferred material.

Anyone know if such tubing can be found?

Thanks for any direction/suggestions.

Try some of the bigger hardware stores I have gotten some that size and larger.
They sell them as foundation molds. and come in lengs over 6' John

The cement forms (sonotube) that I've seen at my local building supply
are in 6", 10", 12" and 16" diameters.  They have 4' lengths and 12'
lengths.  They are not guaranteed to be exactly those diameters.  I
recently got two 12" dia tubes that are actually 12 13/16" OD.  From
what I've seen, you will find the 4' lengths at places like Home Depot
or Lowes, but to get longer tubes you need to go a more "commercial"
type building supply house.  In the Seattle area, "BMC" is the
location I found the 12' tubes.  I'm not sure if an 8" diameter is
common.

FWIW, the sonotube interior cardboard is soaked in wax to allow for
easy release from a cement pier, in case that makes a difference.

Also, I assume you've looked, but just in case you haven't, what's up
hobbies, loc precision, pml, etc... all carry tubing, but 8.25" isn't
a standard diameter.  They may be able to special order some for you.
  But, Performance Rocketry does have some 8" and 8 1/4" tube in
fiberglass.  http://www.performancerocketry.com/airframes.html

All, Thanks for the replies. You have been informative.

Dave, I did look at some of the larger modle recoket online shops,
but managed to miss performance rocketry. While I'm a bit intimitated
by working with fiberglass, that may be the best option.

Thanks again,

Art

Hi Art,

I am not sure where you are located, but there's a tube manufacturer here in
Houston:

  <http://www.yellowpages.com/info-LMS57644847/Johnson-Paper-Tube-Co> Johnson
Paper Tube Co.
3562 E T C Jester Blvd
Houston, TX 77018
(713) 263-8820

I have been there a few times and he has all different sizes and
thicknesses. Give him a call and I bet he can hook you up. He will even make
custom diameters (but it's expensive and you have to order a truckload).

(FOR THE REST OF YOU, THERE WAS NEVER ANY TUBE IN STOCK SUITABLE FOR HPR, SO
DON'T GET YOUR HOPES UP.)
