The basis of this post was taken from my reply on another forum talking about 3D printers and software. Thanks to Michael @ IndyCals for recommending Sketchup to draw up 3D parts, I got this part done in something like an hour including time watching the intro videos. In contrast, I spent hours watching Blender tutorials without still even a clue how to make something like this in that software. Without further ado, here's my wing from SketchUp:  Top is a 3D view of the wing. The bottom left is an interior view (deleted outside of endplate temporarily). The bottom right is the drawing which I based my 3D model off of from an old USA Today article on the Handford Device circa 1998. Upon closer research from race photos, I don't think the drawing has the dimensions right so I took building this 3D part as a learning exercise. I know where some 1:1 cars are being held so I am hoping that maybe a fellow board member can allow me to measure them so I can make some accurate 3D printed parts later this year. All in all, not too bad for a first effort I guess. It is certainly nothing to the level that we have seen out of IndyCals, that's for sure!  Jordan |

This is a whole new world and I have to admit I do not understand it but it will do wonders for us model builders.

Very nice! I might have to give it a try.....it might help in making illustration for my instruction sheets.

Is Sketchup free? I'm looking at the site...I dont see anything about paying?

What's the typical width of a wing end plate? I'm talking the full size car. I'm planning on making some wing end plates of my own but from plastic sheets and don't know what thickness to buy.

Very nice! I might have to give it a try.....it might help in making illustration for my instruction sheets. Might be easier to do it in a 2D program - something to consider. Is Sketchup free? I'm looking at the site...I dont see anything about paying? Yes it is free, there is Pro functionality that is free at first (I want to say first 7 hours of usage) but then you have to pay to keep it. However, SketchUp works fine without the Pro features. There is also a plug-in to export the file for use at places like Shapeways. What's the typical width of a wing end plate? I'm talking the full size car. I'm planning on making some wing end plates of my own but from plastic sheets and don't know what thickness to buy. Maybe someone else can say for sure as there are probably a few guys with endplates in their memorabilia collections. For this test I did the endplates at the kit thickness, to be 3D printed the material used to print will determine how thin the endplates can be. SketchUp makes it easy to adjust the part so I could easily adjust the endplates to suit a particular material. Jordan |

I've used aluminum from pop cans for end plates. To thin?

I'm waiting for our new computer to arrive (Got to update from XP) so I don't want to bother to download anything at the moment. I have a student version of AutoCad (non 3D) and will continue to have it on our new machine. Does anyone know if Sketchup will support AutoCad files?

Great work! Hit me up if you ever need parts...I have tons from multiple years I can just toss you and you can modify as needed. I wish you and Michael would hit me up for them  |

SketchUp will take AutoCAD files. I frequently use 2D drawings as the base/starting point for 3D in SketchUp

Quick public thanks to Michael Portaro, he's given me some good advice that got me to prep this part for 3D printing. It has been a great practice for what I need to do once I have a piece with accurate measurements.
Importing a 2D drawing would be helpful, I have an outline of a part in CorelDRAW that I would love to model in 3D. Importing it would save tons of time getting the buttons and curves laid out correctly.
Anyone have a 1:1 late 90's endplate they could measure the thickness of for Stu Boyle?

Not counting the trailing edge which had a lip, my 1999 short oval RWEP was 0.2" thick.
edit: BTW, does Sketchup offer the ability to overlay an image on a plane for tracing? Solidworks offers that and is excellent, but don't have the ability to get SW for home.

I have a 1991 Lola RC rear wing (off Michael Andretti's cars that season) as my bar...i can go measure the thickness of those endplates. They have to be close to the same thickness. They are about the same as the old Dallara too.

Why not just make a resin copy of the 1/18 Action Lola SW wing? It is one of the few things Action got accurate.

I looked at my Kenny Brack 2001 Lola but it looks like the MKII for the short ovals!? I'm drew this in 1/25 car because that is my personal preference. But, if there was sufficient demand, then I would certainly redraw a piece for 1/18. Jordan |

How is the Brack rearwing different than other years besides the angle of the flap? Seems pretty much the same to me, and Ralph can attest to my pickyness.

How is the Brack rearwing different than other years besides the angle of the flap? Seems pretty much the same to me, and Ralph can attest to my pickyness. AFAIK, there were three iterations of the Handford Device that raced: 1. Superspeedways starting in 1998 (Mark I, MKI) 2. Short ovals in 2000 and 2001 (Mark II, MKII) 3. Superspeedways starting in 2001, an update to MKI with an extension to the lower part that hangs down I think there was talk of a Handford Device for road courses but that never saw the light of day AFAIK MKI  MKII  Original MKI  MKI with extension  I looked at my Brack car maybe two weeks ago as a reference and was sure it wasn't the MKI. It might be accurate to the MKII. I can't say for sure about it being right for the MKII because there is literally nothing out there about the MKII shape. I could eyeball it based off of photos but there is still a chance I could see the 1:1 so to me it is not worth it to guess.... yet If given the opportunity, I'd rather invest the effort and hours to get it as right as possible. To me, the shapes of the MKI and MKII are totally different. I want to do both and fully expect to have to build entirely different cross-sections for the different rear wings. I would welcome more insight and discussion. I have spent a lot of time digging for more information on the various wings of this era but I certainly still have more questions than answers. Jordan |

Jordan I just love your passion for the Reynard! Thanks man, it is a blessing and a curse A Handford decivce would work with Swift, Eagles, Lolas, and Penskes, too! Getting the right measurements is key now and learning how to do more complex parts. I picked a relatively straight-forward first project for a reason! Tons of stuff I'd love to do - just have to figure out how to do it! Jordan |

Any thought to making any 1/18 Champ Car look like this?  |

Post by indy on Jun 2, 2014 15:21:52 GMT -5
Yes, I have thought about doing the last generation Lola ChampCar. I have something in 3D reasonably close to the car's shape. However, it was developed for a different purpose so it needs a lot of time on it spent massaging to make it printable. Along the way, things like naca ducts, panel lines, etc need to be added, too. Additionally, the shape needs to be manipulated to engineer a way to assemble the pieces. I wouldn't expect it to be cheap, either, given the amount of material in 1/18 cars. I really hope most/all of my projects would have an interest in both 1/25 and 1/18. Right now, I am still working on getting some 1:1 measurements for my first few projects. My latest project was ideally a straightforward piece that was only a baby step beyond the above wing, but turned out to be very complex to get the shape right. I do appreciate those that have graciously let me pester them during my process, including (but not limited to) Calvin Sallee, Michael Portaro, Michael Peters, and Stu Benford. At this point, making money is not my first priority. So, I will mostly be favoring making pieces that I always wished were made... and it might be stuff that's not a big deal to other guys!? Still if I want it, that will be enough for me to draw it. I would always like to have finished parts up for printing in small-demand situations and if there was a item with enough popularity, resin copies would be an option (molds and resin pieces poured by someone experienced which is not me ). That's still a ways off at this point - I still have no 1:1 measurements for any current projects and that's a big hold up right now. Oh yeah, I am still pretty new at this....  Jordan |

Some day I'll be saying to you......"remember back in the day when you couldn't figure out how to draw so and so part" Sooner of later you'll be drawing up some really impressive stuff.... Some day you might have your own line of upgrade parts and hardcore resin kits! Jordan's Revell Reynard multimedia high detail upgrade kit $100.00 Jordan's Revell Reynard Superspeedway conversion kit $50.00 Jordan's 1/25 high detail 1991 Rick Mears Penske kit $350.00 |

Jordan In any case, that picture of the white/purple #2 Pacificare Lola Ford driven by Oriol Servia is my favorite Lola-Ford of the 2005 Champ Car Season that I'd love in 1/18. In addition, I don't suppose you'd be able, with your 3D printer, to rearrange the 1/18 Minichamps Sauber BMW F1.08  to look more like this?  |

Haha, Calvin, I'm not sure many (if any) would pay $350 for even a MFH-like 1/25 Indycar. I think I will just do pieces to start off - wings, rims, steering wheels, etc. Pretty easy to see the ideas I have for future project possibilities fall into my three favorite interests - a certain driver, a certain era, and/or a certain race @racingfever the Lola is staying on my radar. However, that Sauber is not something that I seeing me doing, and it might be easier and cheaper to find a diecast customizer if there is a similar car already offered in 1/18. Jordan |

Much quicker, easier, and significantly cheaper. I think there is still a lot of misconception about 3d design/printing and what it is good for. Nobody is going to be spitting out full 3d printed kits at affordable prices anytime soon. |
