Before I got all tied up in teardrops I started playing with tiny houses...

Here is a 10x10 simulated timberframe home model I was playing with...



Now that I have a little more free time I'll have to model up a couple ideas I have...

You guys have a nice collection of photos and ideas!

Welcome to the forum.   :)

Do you mean Teardrop trailers or the h20/NaCl kind that come from the eyes?  :'(

That is a good looking model. What did you use to build it?

Before I had enough courage to start my framing project,
I built a few scale models of the walls I had in mind.
Because I wanted to try a couple of different framing techniques,  I scaled the plans down to make 1/8" thick balsa equal the thickness of a 2x6.
Doing this gave me the insight I needed and made me not so afraid of cutting up $2000.00 worth of lumber!

BTW,

A lot of teardrop technology can be applied to tiny houses also, as you probably already know. Things like electrical, solar, propane, 12v appliances, light weight construction, fiberglass, uniflex 255, etc

Consider this another good place to ask questions... very fast and responsive group of people...

I figure I'll have a teardrop parked in my back yard of my tiny house, for guests...

Yes! I've always toyed with the idea of a tear drop...now I have a place to explore....after the house.

Definitely the first... teardrop trailers...

Oh, and typically when I say I am going to model something, what I mean is I'm going to make a CAD model. CAD models go together faster for me than little models made out of wood. (Although the wood thing is fun from time to time, and therapeutic too!)

What I'd really like to come up with, ultimately, is a tiny cabin in the woods that is off the grid, and can sustain itself indefinitely. I thought I could achieve that with a trailer, but due to size, there are all kinds of problems. But hopefully those can be overcome with a stationary design.

I started with some 2x4's and cut them down on the table saw to represent 1/4 scale studs. I have both 2x4's and 2x6's represented in that model.

I plan on building another scale model someday, one of the ones I saw on this forum btw... It was that 199 sq foot tiny house, I think it won a prize here on this forum... Incidently, in my town the largest I can build is 120 sq ft.  :(

Oh, I forgot to mention, here's a list of over 150 teardrop albums that you can look at...

and with that I'll focus my discussions on tiny houses...

Does anyone have any solid models of windows and doors in either parasolid or acis format?

A few years ago I wondered about building a teardrop trailer for a guest house--no wheels, just the body set on blocks.

I had never heard of a teardrop trailer before today.  Maybe I'll just buy a house and build a trainer.   ;D  Those are really neat.

The teardrop shape must have its own allure.

As I understand it the idea is based on a 1930's concept of streamlining for a less disrupted airflow at high speeds. Chrysler built cars during the era that followed the basic shape. Turns out that when the real science was done, a much more blunt shape performs far better. Here is a new Mercedes design - the most slippery so far.

Now, I have to ask, why would someone want to build a low speed structure (like a house) based on a failed attempt at streamlining? Is this like the "sphere house" that was posted a few weeks ago - totally impractical but also totally unique?

That's the Chrysler Airstream.  Neat looking cars for their day.

In it's purest form the deardrop is the most natural shape for the least amount of drag from air.  Watch a drop of water fall in slow motion or still of said drop and you will see a tear drop about 1/6 in diameter as it is long.

I have a far fetched application!  Build a streamlined house that would rotate into the wind like a weather vain in Hurricane conditions.

LOL... I have visions of things getting flung off shelves and things getting turned over from sudden changes in wind direction.  You would have to slow the movement down somehow.

Sure would be different.

I can see you and raise you 10...

I have a plan for a generic benroy, completely free, with all the detail of the kuffelcreek plans, and maybe more...

you can view it here... http://www.mikenchell.com/forums/viewforum.php?f=34&sid=4b236f88ba56ec48fe9573ad0ff42949

Enjoy... and if you really are interested, save it to your harddisk...  ;)

Mike...

P.S. This is what the generic benroy looks like...


P.P.S. I am reloading my CAD software as we speak... so I can start modeling my tiny houses...  8-)

I have the plans.  great guy great plans

Hi John,

It's nice to meet you... you're doing a wonderful job here...

You have to clarify your question though. Are we talking about houses on wheels that we only move once every few years, or houses that we drag from campground to campground every few days?

The teardrop is awesome no doubt...But let's not forget that gravity plays a huge part in the shape of the teardrop...And that the water is accelerating at 9.8 m/s squared.

The shape of the tear drop is the combination of the density of the liquid(with the forces of gravity working on it) and the resistance of the air against it as it falls.

It is different when you move a solid object  horizontally and  the effects of gravity on the object are of no consequence.

Still pretty useful to observe and learn what you can from the teardrop. I just think people overestimate that shape when thinking of aerodynamics.

We do not drive drops of water from space towards the earth...Occasionally we like to drive horizontally ;)
