I have an old book from about 30 years ago by an Author , named Jack Lambie. Very informative and practical and provided valuable guidelines to make usable parts the first time out. He authored numerous books before his death in 1999.

Although out of print, you can still find examples of the book on Amazon.

Here's a listing of the Jack Lambie books on Amazon. Do you have one of the ones listed? If so, which one?

Edit...how in the heck did I fergit to post the link?

Deep Thoughts by Jack Handy

The face of a child can say it all, especially the mouth part of the face.

Remember, kids in the backseat cause accidents; accidents in the backseat cause kids.

I can picture in my mind a world without war, a world without hate. And I can picture us attacking that world, because they'd never expect it.

It's easy to sit there and say you'd like to have more money. And I guess that's what I like about it. It's easy. Just sitting there, rocking back and forth, wanting that money.

"It takes a big man to cry, but it takes a bigger man to laugh at that man."



Ohhhhhhh... LAMBIE.

Thanks Frank...!

OK, my "1/6 Scale" VW New Beetle model car came today, and at first look, it looks pretty close to the Tamiya 1/24 model I have. It will be MUCH easier to make various Aero add-ons to try and help the flow. It may be possible to do some simple Wind Tunnel testing.
It is pretty obvious that the car body needs to be lowered, as they must be built for "Cowboys"... they do not take their hats off...ever. Well "almost" never!
In another thread I saw a conversation about streamlining a New Beetle, going in the "Normal" direction. I've got some ideas there too, I can play with.

Instead of chopping and filling the body consider just setting the location of the wheel in the [new] front wheel well and then just rotate the whole body around the axle line, e.g. pie-cut the bottom of the doors. A splitter at the new bottom and you're done.

If you find time,you might be amused at how Volkswagen Group AG 'lowers' their cars on a performance price basis.
Compare:
*Beetle
*Audi TT
*Porsche Panamera
*Audi A8
*Bugatti Veyron
*Porsche 911 GT1 (1996)
*Lamborghini Venemo
-------------------------------------------------------------------------
The more you spend,the greater VW gives you increased fineness ratio,Hucho's recipe for low drag.
*VW's Lamborghini Venemo has a greater fineness ratio than Paul Jaray's Cd 0.13 'pumpkin seed,' Kamm's FKFS Cd 0.12 'pumpkin seed,' and the Aerodynamic Streamlining Template.For $4,000,000 you can have one!
-------------------------------------------------------------------------
Anything you can do the add elongation,whether by cutting down the roof height,or actually lengthening the car will pay dividends with the Beetle.And you can add plan taper,something lacking in all the cars mentioned.

$ 4 Million...Hmmm...where did I put that coffee can?

Here is some small progress I am making on the 1/24 Beetle models, before I start on the 1/6 model. I plan on making a mold from the 1/6 car so I will be able to pour several bodies from it, without destroying the car like I have these 1/24 cars. Also is a piece of rectangular stock I will use to build a scale simulated fiberglass, bamboo, or laminated cardboard, composite frame, for the old Beetle and he final X-Car.

Here is the current stage, of my taking 1/24 VW Beetle models and modifying them into a more aero design. I am calling these NS for the New Style Bugs and OS for the Old Style. When I get the NS 1/24 scale body the way I like it , I will make a mold of the 1/6 scale NS Bug I have, make foam cores, and work on those with a small wind tunnel. This is the body type I'd like to use for the Final X-Car. However, I have decided I would also like to take a Live OS car and make the mods to it, recording the changes as I go. First with a stock good running OS Beetle, then lightening it and aero mods as much as possible, then do the full Aero body with the back forward, and finally go to the full composite frame. I think if the full Aero body worked well, it could make a good kit to sell to bolt on the old pan cars. The model body seems to want to be changed "easily", I don't know how accurate it is compared to the full size car, but by cutting the front off at the cowl, and "welding" the rear seat-firewall section on, it now becomes the Back of the Aero OS nicely. I widened the front axle to better allow the cab forward design I am looking for, it turned out to be a little too wide for the OS car, but just right for the NS.
I hope everyone had a Fine Christmas!
