Hi Gary,

How it took in hours is an good question. The last 3 years I work about 5 hours each day, 7 days a week. Sometimes more, sometimes less. That´s round about 1825 hours. The 5 years before (when I was in job) it is not so easy. On sundays 5 hours like above, ok. But not during week and on saturdays mosly in fall and winter.

So if I say

sundays: 52 weeks x 5 years x 5 hours = 1300 hours

and the saturdays: 26 weeks x 5 years x 5 hours = 650 hours

total: 3775 hours for build up the model (less or more)

To that you have add the hours for CAD engineering, for searching in the www and documenting. Because at the end I create a litte book to the model (like I always do) with it´s emergence.

If I´m done with the model? No, I think that should take a while. There are a lot of points that do not fit.

The joint from fender to hood is not parallel, the rhd door could open a bit more, the substructure of the bench ist not like origin and the coating must wait til spring til the weather is optimal for coating under the carport. Little bit warm and dry.:nabble_smiley_beam:

greetings, :nabble_anim_working:Tobias

Man, that is a LOT of hours! But probably similar to what some of us put in for restorations or transformations on the full-sized vehicles. So it makes sense.

And the idea of a book on the results is a good one. In my case I use this forum to document what I've done, but a book that you can display at a show is good. :nabble_smiley_good:

to create a book is fine thing. Totally other stuff than a model of course. But I like to have it in my shelf. And in the case the pick up will be sold, I still have book with report. :nabble_smiley_beam:

Hi Guys, thank you all for your comments :nabble_smiley_good: Obviously there´s still no big error happen in the buildup otherwise you had told me...

@ Jim: yes, you are right. It would be a lot more difficult without CAD, precisely because I am a CAD-guy. Before starting sth I need the data. And, of course, it´s even easier to modify sth.

:nabble_anim_working: Tobias

so, the electronics. My favorits - lol -:nabble_smiley_wink: All i know about electricity is that it exists. So you can imagine that it was hard work for me to create a circuit diagram :nabble_anim_crazy: and the cabling. But in the end everything works and I am 5cm taller :nabble_laughing-25-x-25_orig:

the purchased parts

Power distributor with 6 connections. The left one with connection with the grid.

The flashing electronics. The timing of light and pause can be adjusted on the two potentiometers.

LEDs with 5mm and 3mm diameter. The color of the light is 3000K warm white.

For the wiper a gear motor with 30Rpm. This is a Radial fan from PC area.

good speed for a wiper. Unfortunately still big.

It was to decide: build up the engine compartment like the origin or should I use the space for electronic equipment? The first option entails to have separate box for the electronics outside of the car and in my opinion, that is bad option.

The 6V mains connection was placed behind a flap on the right-hand side of the car. If necessary, the power can then be easily connected.

assy group 31 / sealings

I looked for different profiles from the window area. It should be a profil with a tube in best case, otherwise I would also take a lip-profile.

In the end none really fits well and I remember (dark and far away...) when I was still in job (it was in company for car sealings) I had already organized a piece out of waste that is good enough for my model and that suits well.:nabble_smiley_beam:

Now, there is only one assembly group to report left. the number 29, the steering is still in work and I report when it´s done. Also when further steps will be finished.

see you here :nabble_anim_working: Tobias

Very impressive Tobias!

Before beginning this kind of project, do you list all the assembly groups you're planning to proceed with?

If so, I am curious about that groups list, how many of them do you need for a model that kind?

I think placing all of the electronics under the hood was a good idea. I don't know where else you could have put it, and there you can easily get to it. :nabble_smiley_good:

But that sure is a lot of connections! And a lot of LED's. :nabble_smiley_oh:

Hi Jeff,

this project was running out all boundaries. It was planned as model of the body with all closures and some highlights and the purchased chassis (XC-CC01 from Tamiya) you see in the first post from me. However, the XC-CC01 chassic does not fit - it has another scale although they sell body and chassis as 1:10. But the body is 1:13 if you make the trouble and measure it.

And so one thing leads to another. One day I realized, it will be better to have a part list and so it grows step by step.

My projects do have a "headline". Two examples: one model stand under the headline: "can I combine these different materials and what happens?" There was a PE foil, ABS plastic, brass, cyanacrylat glue, aluminum-filler and aqua-paint. An interesting mix.

Another was a HERPA car model. Do you know HERPA? It´s for the model railway H0 1:87 very tiny. The headline was: "is it possible to build a retractable top for this and when yes can I cover it with fabric?"

And so the Ford pick up stands und the headline "is it in scale feasable (for me) and to witch conditions?"

To your question how many groups I need: there are 32 assembly groups. Eventually you can add one for the colors.

Hello guys,

yeah - the steering is done!:nabble_anim_confused:

It was bit tricky, the devil was in the details. I started with the tie rods and the lower steering shaft. The steering tube can be pushed in to compensate the deflection of the body.

Bild_1.jpg.864110ec7f12a0e4a1ce0af6abd345dc.jpg

Bild_02.jpg.4c1e212a4b64e3ecdb4caa92171c89ff.jpg

The steering gear box witch should have a scaling faktor from 1:3. More was not possible, the box would become too big. And it must have 3 gears, 2 for the scaling, 1 for change in direction. After all I thought, if the steering wheel is turned left, the steering shaft must turn left too :nabble_smiley_cool:

Bild_03.jpg.1fa5c6f4528923310eebafb870d9b3ed.jpg

Bild_04.jpg.178261e5a582f8545bd5933b4f90446a.jpg

Bild_05.jpg.f1038289f5c667b60f27365beae2bccf.jpg

The gear box is screwed to the floor after it´s fastening to the upper steering shaft.

So far so good :nabble_smiley_beam: and then everything got out of hands...

1. the steering wheel broke into pieces

2. the gear box has an gear too many

3. the cardan joint did not work correct

4. the fastening of Allen screw on flat shaft did not work :nabble_face-with-open-mouth-vomiting-23x23_orig:

This is always a good time for a break and an extra coffee...

1. The steering wheel was soft and weak plastic part and when turn it with your fingers through the open door you need some energy. So I have build it up out of brass.

Bild_12.jpg.607f6560981c00ed45131d6d0174aabf.jpg

2. The gear box... I had thought and thought but not thought through to the end. If the hook at the end of the lower steering shaft swings to the right, the car turns left. So the 3rd gear is useless. That means the box can be built smaller.

Bild_06.jpg.814c29d1d7f8982d278971f50611a4ab.jpg

Bild_07.jpg.4cda0797d7ad284f6605be4b07901182.jpg

Bild_08.jpg.d28eca3dcaa7728544caf70293c986e4.jpg

The bracket for gear box is bent about 10° (arrow). So it isn´t necessary to use a cardan joint to the upper steering shaft.

3. The cardan joint needed some special screws and threrefor some special cut outs.

4. The Allen screw attachments on the flattened shaft didn´t work right. It had to be screwed a little way into the shaft so that it could be guaranteed to be carried along.

Bild_13.jpg.bacbc5e5e79cbccba2b3166aef82319a.jpg

Bild_14.jpg.1a055e6f9586b773c30ac113270d655b.jpg

So that the steering can work, a guide must be installed. The elongated holes must be very close to the steering shaft.

neutral position for driving straight ahead

max left steering angle

max right steering angle

You can also see the angle-difference of the inner wheel to outer wheel. Obviously the implementation of the steering harness was sucsessfull :nabble_anim_handshake:

At the end, it works. Greetings, :nabble_anim_working:Tobias

I'm still gobsmacked! :nabble_anim_claps:

So, did you rebuild the steering box? I think I missed that. Either way, it is impressive!

And that steering wheel is awesome. It is obvious that it is for a Bullnose. :nabble_smiley_oh:

Hi Gary,

no, you did not miss something :nabble_smiley_good:

I reported it only in that one post that there was first a 3 gear box that then had been modified.

Tomorrow, I start the automatic transmission box.

have a nice day... greetings :nabble_anim_working: Tobias
