Construction of a Continental Mark II model, scale 1:12

Recommended Posts

Yesterday, I could finish the base wheelcovers. They are polished, ready to be chromed. Only the fins are missing. Now, I have to begin them...

It took about 3 hours to do...OK, it's the first one, I had to fabricate a jig and I must improve the milling process to have less manual work after the milling. I expected to have no more than 5 minutes to do one fin; I can forget this optimistic value.

"Only" 239 to go! (there are 40 fins per wheelcover)

For what purpose are the numerous bits in the picture?

No idea? It's the material needed to do the fins. Each part is good for 8 fins; they will be machined, cut, machined agin until they become a tiny fin. I will show you later all what's needed to do those fins.

Now the fun will begin!

2 weeks of vacation = 3 weeks of inactivity to the model. It's amazing how much paper is coming when you're away!

Now that the most urgent matters are behind me, I could begin the mass production!

It begins with the shaving of the stock (necessary due to the lack of precision of my tool) as shown on the first picture.

The the stock is milled with a dentist tool, giving the section of the fins. The length is good for 8 fins. I cannot do more at once because of the limited length of the vice. I have 30 pieces to work at, giving 240 fins.

Thanks for the update, Roger. I was wondering why there was a delay but I didn't want to give you any pressure. ;)

Now that the profile of the stock is done, it's time to cut the bars to the proper length. As you can see on the picture, the cutted part is held to avoid some vibrations and prevent its ejection from the cutting tool (and the associated search on the floor!).<O:p</O:p

Hi André!

Nice to "see" you here! For two weeks, I was probably still in France; we came back on September 15. Next time you come in Switzerland, please let me know. Reconvillier is at 8 miles from the place my cars are stored!

Is your Pontiac ready? Anyway, the frame is good looking!

Yesterday, I began with the mass fabrication of the vanes. It seems that the month October will be busy with milling!

The first picture is showing the special tool I fabricated to keep the part to be milled at the proper angle.

The second picture is showing the birth of the tang which will be inserted into the cover.

The third picture is showing how I'm milling the sides of the tang. I cannot use the disc used in the picture nr. 2, because the machine is not precise enough and the milling tool is cutting on one side where it sould not. With a small diameter tool, the inconvenient disappears.

Then I'm cutting the vane from the ground material and the last picture is showing the end result. The lower brass part is now scrap. The vanes are not yet ready: the ends have to be trimmed at angle.

I'll let you know, maybe this spring for a hockey trip.

Now, I have to trim the ends. After that, each vane is fitted to the wheelcover; this last task showed me that I have to modify a little bit the position of the tab on the next vanes batch.

After the trimming was done, each vane is sanded and polished. Not an easy task with such small parts, but it can be done.

Then, the soldering of the vanes can begin!

It was finished this late afternoon. Oh boy, what a task! Clearly, I underestimated the time needed for the construction. Each vane needs about 1 hour, from milling the ground shape to the soldering. The wheelcovers of the Toronado and the Avanti were indeed much simpler...

Congratulations on the birth of your latest component, Roger. I hope you feel that the effort has been worth it. That wheel cover looks impressive!

Another task perfectly executed. Well done. The model will weigh as much as the real car with that much detail put into it.

Thank you all! The wheelcover is weighting 5 gramms. The completed model will certainly not be a lightweight; however, like I did on the Avanti, I'm looking that it will not be more than 2 - 3 kg.

It gives me a headache just thinking about doing something like that.

I wish I had 1 10/th of your patience.

Danny, I'm very sorry that you are getting mad about me! In fact, I have the impression that almost everybody, if not fitted with 2 left hands, can do what I'm doing. The huge difference, as you noted, is the patience and tenacity I have.

Not mad at you at all mate.:eek:

What you do impresses the heck out of me. :):)

Doing something like that would send me nutso.

I admire anyone with your skill and your patience.

I have low patience with life size.:P:p

Always looking forward to the updates.

The second wheelcover is done. It's quality is a little bit better than the first one: the dimensions of the vanes are more constant.

"Only" 4 to go!

4 wheelcovers are now ready. Enough for the car, but I still have 2 empty "dishes" requesting their vanes. After the second wheelcover, to mill all those vanes is really boring.

To polish the vanes, there is just one method: to pinch them between 2 nails and rub them on 3 different sanding papers: 400, 1200 and finally on a sanding paper I don't know the grade. I have almost no nails anymore...I'm glad it's over soon!

Outstanding job.

The detail on the Quarter is pale in comparison to your wheel covers.
