This is going to be fun!!! I do not have too much information on this car. (And I don't want it, so even if you have the original blue-prints . . . )
I think that I will make a paper model (Cardboard is in the paper family), make a plastic model, and brass. All will be in 1/12th scale.

I hope to have fun and learn or re-learn some techniques!

I wasn't sure where to post this thread? It seems exotic?

To All Paper Modelers! I'm Sorry! But I can't do it! My significant other says that my techniques are losing the "Paper-ness" of the model! -And I have to agree! -I can certainly glue up the cardboard as I had planed, coat that with resin or glues, to stiffen it and give it some stability, but then I might as well be working in fiber-glass or plastic or metal! I could make the tires as indicated in the "kit" but why?, why accept a compromise that I don't need to? I have several lathes, a mill, drill presses, basically I have a complete shop to make almost anything, so why tie my hands? I was hoping to have a quick modeling distraction, but I realize that going THAT basic won't satisfy me. -So? So, I've decided to take what information I've gathered and go for a simple wood/metal build.

Today I cut up some sections in oak, tomorrow I'll continue to dimension the wood, and cut out the wheel wells.http://www.scalemotorcars.com/gallery/data/959/IMG_5058.JPG

. . . for my two cents? I used to sell Pocher kits, about twenty years ago, when they were $200 to $300! And I never sold one without first explaining that they were not "state of the art" models. That they offered a great foundation to work upon, and that they were the only models available (at that time) of the cars that the customer wanted to model. And to this day are the only large scale models of those subjects.

Obviously, judging from this forum, Pocher kits offer some satisfaction, (shared trauma?)(misery loves company?) and I think more? I think that there is more satisfaction from working on a larger scale. The subjects are of some the most beautiful cars made. And when you gentlemen are through with your builds, I think that you'll have something to be proud of!

I used to sell them too. My favorite technique was to ask how much they spent on a hobby in a year. It was always more than the cost of a Pocher. So, it will take a year to finish it- it's a cheap hobby! It usually worked.

And when they asked about tools that were needed the answer was - a small screwdriver-and a good psychiatrist 😁

Hello! This is the best photograph in profile that I have found. Based on this photograph, I've redrawn the silhouette of my model. The plans in Model Racing Replica News #13 are closer than the paper model, except that the seat and cockpit is rendered as a "church pew", (very up-right). The paper model gets the cockpit right, however is, I believe too short over-all.

Using the above photograph, I've redrawn the profile. I hope to every day or so make some progress on this model.

Some questions about the exhaust? How is it routed? On the "Hill Climb" version of this car, the exhaust looks to terminate right in-front of the driver!! (probably just to his left?), but on the "Racers" the exhaust must drop down from the engine and exit?

-Another question is about the "Clover Leaf" access panels? How do they work? In one photograph you can see one on the bulkhead above the seat back, and on most of the other photos, the seat back continues all the way up the bulkhead.

And a final question is regarding the drive shaft and brake lines that run straight back through the rear seat's lower cushion, making one continuous seat back with two seat cushions.

I've just checked my database of specs and sources and found only two:
Racing Car Pocketbook (Jenkinson)
Wheelbase 106 in
Model Car Prototype Parade 220
Wheelbase 106 in; front track 56 in; rear track 28 in

I hope this helps a little

​THANK YOU! David!

The design maxim for this car seems to have been to embrace the unconventional wherever possible!

To All Paper Modelers! I'm Sorry! But I can't do it!

When I was a boy, I had a "Meccano" which of course, offered very limited possibilities to make a car body. I used some cardboard which, by nature, can be bent in one direction. Later, I tried to do a '63 Chrysler but this time, I noticed that, when the cardboard is humid/wet, it possible to have compound curves.
For the model you choose, this technique is not required, but cardboard offers limited properties. Good luck with your project!

Thank you Roger! Was the Avanti (your original Avanti model) was it cardboard?

I like working in wood, especially oak. (I have a very long list of woods that I like to work with.)(not poplar) . . . (it has its place.)

No, Don. It was a big departure for me as I did the body with fiberglass and polyester. I had no experience with these products, I had to learn quickly!
It seems that you are well equipped to work with the wood, I'm not...
