Delage 15-S-8 Grand Prix (1/8)

[sharknose156]

Gee sorry to read this. i hope all gets back to what you want asap, and as you want. 

[Roy vd M.]

Not being a sentimentalist, your reactions are heartwarming to me. 

 

Thanks my friends! 

 

From the 20th of December I'll be a week in sunny Germany for holiday (planned before we had purchased the house so we can't cancel it... maybe for the better, really! Not bad to get my mind off of things for a short while) and maybe I'll have time to make another video log instalment...  

[Roy vd M.]

I decided to just have a go, putting aside other work and relaxing a bit working on the third video.

Marvelous videos! Would like 50 more laps on the track please - at 7500!

Great to meet you 'in person' too!

[harveyb258]

Another superb tutorial, Roy  

Thank you for taking the time to explain.

 

Cheers, H

[Totally Mad Olivier]

Congratulations, Roy, for this new project. I wish you a big hit on YouTube. A question about the Fusion 360 software: I saw it is quite expensive (60€/ month or 498€/ year...). Is there a way to get it cheaper?

It looks great, indeed, and would probably be the best complement for the 3D printer I will get soon. 

 

Cheers

Mr Codger... I'd give part of my lifespan to see this car go with those revs, ideally in a 1927 setting. Last year the 'Florida car' (=the most original one) raced in Brooklands... had I known, I'd have certainly have paid them a visit. Unfortunately I cannot find any video online (at least not featuring the Delage). 

 

Pleased to meet you too haha. whereas I already knew you vaguely resemble the famous actor Adrien Brody, now you finally know what I look like

Each additional follower (Youtube subscriber) is one step toward these videos going viral, thank you for subscribing Olivier! I do appreciate it.

 

Seriously about this being a big hit though... I think we all know that's not going to happen. I mainly make these videos because this way I can explain all of what I'm doing in a more visual and better understandable way. The more people who join in, the merrier.

For hobbyists it is free to use! Just apply for a hobbyist license and you'll be able to use the software without cost for one year. After the first year if you're still using it, reapply and you'll get another year, et cetera. Autodesk uses this system to create a broad user base.

It even has specific 3D-printing options:

No my young friend, not Mr Brody. My portrait is the late, great Marty Feldman...lovable and inept.

You rightfully indicated a generation gap there! 

 

All the while I really thought you had used an amended photograph of Adrien Brody. This way I learn things! 

 

I googled images and must say I now vaguely remember seeing a movie starring Mr Feldman... but that's been decades!

 

Thanks for pointing it out.

Must have been the one with Mel Brooks, I remember that one and I seem to be sort of your age Roy. 

 

Your Fusion video is very comprehensive, but wow it must be a challenge indeed to master it enough to be able to draw a Delage...

In the US, lovable Feldman was a favorite of Mel Brooks. When time permits, see 'Silent Movie' and 'Young Frankenstein' to see him at his finest.

Now fix your loo and build this Delage !

That’s great, Roy. I think you said it in the video but my english isn’t so good and I wasn’t sure I had understood correctly.

Chaps,

 

Not wishing to continue to push Blender vs Fusion further but someone posted a beginners Blender tutorial using the new version (with a hopefully improved user interface) yesterday. I thought it might be of interest to forward the link:

 

https://www.blendernation.com/2018/12/09/3d-modeling-for-complete-beginners-blender-2-8-part-1/

 

I'd just like to add to my voice to Roy's, if you have any curiosity about adding computer tools too your armory, there has probably never been a better time to dabble.

[Totally Mad Olivier]

Thanks Nick for this link. Is Blender free too for hobbyists?

Did you experience both softwares? 

If yes, a review would be welcome, as I have a no experience on this matter?

Of course, the question is not only for Nick but for every modeler (and especially Roy) who would have used both softwares...

Olivier

[Roy vd M.]

Both Fusion and Blender are free to use. I have never used Blender, due to its steep learning curve. As I understand (but I could be wrong), Nick never used Fusion, so I'm afraid neither of us will be able to compare one to the other. Perhaps some comparative videos exist though (make sure the newest version of Blender is taken into comparison). 

 

I do know there are many users of either software and there's a large online community to answer any questions you may have. 

[Totally Mad Olivier]

Thanks Roy for these précisions. If Fusion is easier to use, I will begin with the latter of course, as I am an absolute beginner. I feel like Christopher Columbus with these new techniques and approaches in model making, I hope I will find out new fascinating horizons. In our "Fiat 806 research" dream team, Nick and you were our specialists on high tech approaches... It is with humility that I will begin this new saga...

 

Cheers

[NickD]

Folks,

 

With apologies to Roy for further hijacking his thread...

While bored on hold, I googled Blender car tutorials. There are many both video and text. There are also formal courses. None of them is going to make much sense until familiar with the basics so my earlier post and other beginning videos are the place to start.

I dipped into the tutorials and particularly liked:

 

http://darkscarab.com/view/43

 

It is only text and it jumps from one piece to another but it is good for establishing the principles and general approaches and should give a good idea of the sorts of skills that will be called on.

Regards

Nick

I don't know for sure if Fusion is easier to use but I can't really imagine any software being much easier to use than Fusion currently is. I felt I had a good basis after some ten hours of studying Youtube introductory vids. I certainly thought Blender was too difficult for me, but as Nick says perhaps the newest version has been improved, making it more intuitive. I'm looking forward to hearing Nick's first thoughts on the new version. 

 

Best thing you can do is, compare both programs yourself. Watch a few introduction videos for Blender (Nick recommended http://darkscarab.com/view/43) and watch some for Fusion (I used this one, the first of three videos for the absolute beginner). I'm sure watching an hour of Blender stuff and watching an hour of Fusion stuff should tell you which software suits you best. Beware, time flies when watching these videos, they are extremely interesting and rather addictive. Whether you choose Blender or Fusion, you're going to have a great time!

Not at all, I'd rather have this thread active and buzzing, providing all sorts of information, than passive! 

 

Fusion 360 for machinists
On another forum a very talented modeller told me he liked my explanations but still thought this was all a bit 'high tech' to him. So I thought I'd make another step plan for the same bolt, more understandable for machinists.

 

So for those who know how to use the lathe and mill, the following provides a better insight as to how Fusion 360 can be used. Basically, the same way of thinking can be utilised: work with rough shapes, cut off a bit here and there (by lathe or mill for example) or add something (by bolting or soldering for example). 

Suppose we recreate ye olde bolt, from a brass cilinder. 

 

First we will draw the basic shape the cilinder is derived from: a circle. 

 

 

 

This circle is made 3D by extruding it.

 

An unlimited number of circles on top of one another thus becomes a cilinder.

 

 

 

 

Now imagine working on the lathe. The blue segment is 'cut away' toward the arrow...

 

 

 

 

But we'll leave the cilinder partially intact. That will become the head of the bolt.

 

 

 

 

Using the lathe, we'll cut the thread. 

 

 

 

 

Then the bolt is mounted on the milling machine. In the next screenshot I sketched the hexagon that needs to be milled. 

 

 

 

 

These are the parts that need to be cut away. 

 

 

 

 

In Fusion 360 I'll select the area between hexagon and circle (resembling 'battlements') which I will use as milling bit.

 

 

 

 

That's another way to draw a bolt.

 

 

 

 

Finally the bolt is mounted back on the lathe. I sketched the lathe in the drawing hereunder: the blade is on the left and the chuck on the right (to be recognised by the arrows). 

 

Suppose the bolt is mounted on the chuck. You can already see that the blade will cut off part of the bolt. The difference with a true lathe is, that in a lathe the bolt turns around its own axle. In Fusion it's the blade that rotates around the bolt. 

 

 

 

 

In Fusion you'd select the left shape as blade. You tell the software 'rotate this along the central axis and remove all encountered metal'.

 

 

 

I'm doing these preliminary explanation efforts just to remove part of the mystery surrounding these 3D suits and to share some understanding of how it works, so that those interested will be better able to follow my progress later on.

QUIZ

 

I like quizzes, especially toward the end of the year.

 

I was just reviewing my photos of the Delage, to prepare planning the order in which the several (sub)assemblies need to be virtually recreated, when noticing this image:  

  

 

The photo depicts part of the Delage's brake assembly.

 

At first sight the encircled handle appears to have a complex shape. However, those who have attentively watched the vlogs (or the step plan in my previous post), might have an idea as to how this part may be designed in Fusion 360. 

 

Hint: you'll need four steps. The first step is, just like in the step plan, to draw a circle. 

 

Quiz: try describing the remaining three steps. 

 

Solutions can be posted in this topic or PM'ed to me, either today or tomorrow. Have fun!  

 

[harveyb258]

Draw circle,

extrude to length,

turn shaft and finally shape the end.

[harveyb258]

Was just admiring that beautiful assembly and flat rivets. Those rivets look like plasterboard nails.

[Roy vd M.]

That's about right Harvey! 

 

Yes the assembly looks really vintage and really nice   

 

Here the full solution: 

 

 

[Schwarz-Brot]

Not sure about fusion, but using autodesk Inventor every single day my approach would be two steps: Draw the outer shape of one side of the "bowling pin" to its middle axis. Make the middle axis a rotating axis. Step two would simply be turning 360° around that axis. This is a very powerful function in inventor, that lets you simply create parts that have complex rotational shapes. Maybe fusion can do this, too. Have to get me fusion and play around a bit.

 

Edit: Great to see this thread coming back to life.

[Roy vd M.]

Thanks for being back in the thread as well! 

 

Yes it's been difficult to find time for the project, with so many things coming up in the realer version of life. 

 

You're right about the two-step tactic being easier and quicker. But I did show exactly that in the video, see from 3:01. My choice of presenting this after the four step-plan was because I think most machinists would find the four step-plan easier to understand as an introduction. 

 

 

 

 

[Schwarz-Brot]

Sorry Roy, I did not bother watching the video. Time is precious in this busy time of the year, a busy job scedule with projects going nuts and a 1:1 house to rebuild.

As I said working with inventor is my job. So feel free (all of you!) to ask any questions regarding modelling in Fusion or Inventor. I pulled the plug and downloaded Fusion to play around at home and crosschecked my method from above. The tools are similar enough to inventor to use without a real learning curve. So if there's anything you cannot figure out, drop me a line. I might not help with freeform- and spline-designs, though. This is something I plan to explore next.
