Heart Failure Posted November 2, 2022 Share Posted November 2, 2022 Always loved Group C and its iconic cars. I have to build my favourite car of the bunch. Started with the mandatory box photo. I planed to detail the car and give it a bit of life and something to look at. 3 Link to comment Share on other sites More sharing options...
Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 Looking at the kit itself, Tamiya did a very good job of giving you the option to display the engine. I have also committed on displaying the front cowl and both side doors open. These are moulded in one piece so the only solution is to cut it out. Problem is the complex shape of the car and its curved all over. Very tricky and easy to mess up but I carried on, with a very agonising pace. Here it is all cut up plus the kit draw first blood, luckily a CA glue is near by to stop the bleeding. 9 Link to comment Share on other sites More sharing options...
Sabrejet Posted November 2, 2022 Share Posted November 2, 2022 Nice work so far! I built this kit when it first came out and it's all a bit clunky but the shape is good. It really needs vacform screens - not sure if there is any aftermarket? 1 Link to comment Share on other sites More sharing options...
Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 I tried to look around and get some after market for added details but its always out of stock and was not lucky enough and if you find one in ebay, the asking price is too much and postage plus customs. So I decided to make some of it out of some scraps that I have. First up are the brakes, I noted that the restored C9 have a slotted brakes but some old photo shows that its was plane but vented (not drilled or slotted). A lot of discussion about slotted or drilled disc brake around and it has its pros and cons but one thing is for sure, it makes the disc brakes looks nice. Anyway, I powered my Myford S7 PFX and gave it a go. Machining at this scale requires full concentration but happy with the results. The series photo will show how I tackle it and the final results. Here you can see the original disc brake parts and besides it the number of parts I did on my lathe to recreate the rotor disc. Some closer views. Each assembly consisted of 3 rotor disc, The inner and outer side and the central side to simulated the vents (which is done by a knurled part). 5 Link to comment Share on other sites More sharing options...
Vesa Jussila Posted November 2, 2022 Share Posted November 2, 2022 This is really nice kit. And you have done good start. I am afraid that there is no vacuformed available, but those are not too difficult to make yourself. 1 Link to comment Share on other sites More sharing options...

Yes the parts are thick especially the curb side body. I have not really paid much attention to the wind screen but thanks for the heads up. 1 Link to comment Share on other sites More sharing options...
Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 Next series of photo shows the rotor disc dry assembly to see how it looks. That's a 2mm diameter toothpick in the middle to check concentricity. Note that I have to adjust the disc thickness to around 0.035 thousandth of an inch. 7 Link to comment Share on other sites More sharing options...
Sabrejet Posted November 2, 2022 Share Posted November 2, 2022 I think that will look great with a dark wash 1 Link to comment Share on other sites More sharing options...

Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 After turning the central hub carrier I fired up my milling machine to recreate details on this part. Center hub after lathe turning. Note the 2mm toothpick Here is the mill set up. I'm running an Emco compact 5 milling machine for this tiny parts. Dividing plate and a dividing head for accuracy. I used a 2mm 4 flute milling cutter to achieved the details. With my glasses on plus a magnifying lens, I still struggle to see it while I cut so I relied on my calculation and lead screw movement to get it right. Doing this several times and maintaining repeatability at this scale with manual machining is challenging. Closer look at the scallop cuts. That's a 2mm 4 flute milling cutter doing its job. Depth of cut is around 0.5mm on a 1mm thickness part. One wrong move and I can damage my 3 jaw chuck! 4 Link to comment Share on other sites More sharing options...

Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 Results of the scallop details on the center hub. Doing ten precision cuts x4 and calculating the travel mentally is very exhausting. Indexing count, slide movement count and depth of cut. At the end I'm very happy with the out come. 5 Link to comment Share on other sites More sharing options...
Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 This is how it looks together with the rotor disc which I adjusted the thickness to 0.035 thou of an inch for close to scale size. Note the 2mm toothpick for comparison. 5 Link to comment Share on other sites More sharing options...
Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 Now the completed rotor disc and hub assembly. Note the further detailing added to the finished part. Until the next update and thanks for dropping by. 6 Link to comment Share on other sites More sharing options...

If you have the engine, interior and the front end that would be amazing. Just post it her in the thread as this will be a nice discussion also. I’m also keen to see your 1/43 kits. Thank you Sabrejet! Glad to have you on board Link to comment Share on other sites More sharing options...
Sabrejet Posted November 2, 2022 Share Posted November 2, 2022 I do have some detail shots but only period 'race' shots. These are Donington: And Brands: Note the third T-car at Donington. I always preferred the C9 in 'sprint' config 4 Link to comment Share on other sites More sharing options...
Sabrejet Posted November 2, 2022 Share Posted November 2, 2022 These are contemporary front-end photos. I'll post these at full-size so you can hopefully pick up details. Sauber always put the chassis number on the front of the radiator shroud - same with the C11. Not sure why this one is '01B' - Kenny Acheson now owns this car. 4 Link to comment Share on other sites More sharing options...

Heart Failure Posted November 2, 2022 Author Share Posted November 2, 2022 Wow! Thanks so much Sabrejet. It’s so clear. There are a lot of photo on the net but the ones you have are so unique! Love the detail shot you did. If the C9 is in sprint configuration, do they max out the engine power? I’m sure the boost will be a bit higher as fuel economy is not needed for the endurance race? And is the front splitter extended? How about the rear wing? I understand during the endurance race they just used the single aero foil on the rear wing, is this correct? The C9 is such a beautiful car. Link to comment Share on other sites More sharing options...
