Vesa Jussila Posted December 25, 2022 Share Posted December 25, 2022 Real interesting way to make these parts. Innovative thinking. Link to comment Share on other sites More sharing options...
Brandy Posted December 29, 2022 Share Posted December 29, 2022 If this works, I'll definitely buy a bonnet set from you for mine! I already have hinges, I was just trying to figure out how to think the panels. The other issue for me is the machine turned dashboard..... I'll be watching! 😁 Ian Link to comment Share on other sites More sharing options...

Noel Smith Posted December 29, 2022 Share Posted December 29, 2022 Would that be a twin cam engine to make a Type 51 from the Italeri Type 35B Nick? I think the dash is a bit different to the 35B as well. Link to comment Share on other sites More sharing options...
nick Posted May 12, 2023 Author Share Posted May 12, 2023 Morning all. Re cunning plan, this bad boy finally showed up:- Theres a bit of a learning curve it turns out. Anyway, after much reading up, heres my first toolpath simulation to try with it. I know we are all used to seeing stills on here, so remember to press the play button bottom left - this is a video! I’ll try not to scare the horses Can you see what it is yet? Problee cant say that anymore. Anyway. Metal next. eek. Nick 1 Link to comment Share on other sites More sharing options...
PROPELLER Posted May 12, 2023 Share Posted May 12, 2023 A dashboard perhaps? What a machine! I do love the emergency red button... Dan. Link to comment Share on other sites More sharing options...
nick Posted May 12, 2023 Author Share Posted May 12, 2023 Heres a quick test Piece made with the laser module And 2D acrylic milling/engraving It is very good in fairness and worth the long wait to get it. Nick 4 Link to comment Share on other sites More sharing options...

nick Posted May 13, 2023 Author Share Posted May 13, 2023 This isn’t my video, but here is a demo of the 4th axis and what it can do. I haven’t tried this in anger yet. My previous post had a non-obvious video in it (the toolpaths) if you want to look again. Link to comment Share on other sites More sharing options...
nick Posted May 13, 2023 Author Share Posted May 13, 2023 It is of course the instrument panel including the elusive machine-turned finish. I’ve still to perfect the right tool for this, but I’m going to try a cork-faced bit and some FFFF grade pumice powder that I just acquired for the purpose. I’m hoping the extreme consistency of the CNC machine will be my friend here. We’ll see soon enough! I’ve got various flat end mills and other weapons to fall back on too, one way or another I’m determined to solve the dreaded engine turned dilemma once and for all. watch this space!

nick Posted May 16, 2023 Author Share Posted May 16, 2023 So of course, it’s not that easy. I made a tool by facing a 1/8th brass rod with cork, this coupled with my pumice powder, isn’t too bad. The issue is wear, so as the tool progresses, it gets fainter. I think I can solve this by forcing a few tool changes, each time the tool is loaded, it gets zeroed, this would allow for wear. the main problem is unexpectedly the cutting out part. I need to get familiar with the machine to get a clean, smooth cut. This is just my inexperience with the machine and feed and speed rates, I should be able to solve this with some testing (of plain aluminium before all the time-consuming machine turning!) So not a COMPLETE failure for version 1, some useful lessons, but most importantly, think I can get this to work! thanks for looking Nick 5 Link to comment Share on other sites More sharing options...
nick Posted May 16, 2023 Author Share Posted May 16, 2023 Some time later... I reckon that's not far off now. 7 Link to comment Share on other sites More sharing options...
nick Posted May 16, 2023 Author Share Posted May 16, 2023 I’m going to experiment with some different abrasives and materials for my engine turning, but I’ve basically cracked it I think. I’ll design and print the instruments next which will bring it alive. I’m thinking of vac-forming the two sight glasses for the fuel system as they have prominent curved brass tubes inside them. In for a penny… I’ve also drawn the Bugatti type 35 instrument panel now which I will use a similar technique for now it’s working. I’m incredibly impressed with this machine, now I’m getting the hang of it. I’ve been playing with the 4th (rotary) axis today, who new this old piece of sycamore that's been lying around in the workshop for years had this bust of Nefertiti hiding inside it all along? ok I could have easily just 3D printed it, but it shows off the accuracy and resolution of the milling really well. And you can’t print wood. 5 Link to comment Share on other sites More sharing options...
Chaoarral Posted May 17, 2023 Share Posted May 17, 2023 Is this the machine you were waiting for to print the Bugatti 35B and Cosworth DFV upgrade parts? Link to comment Share on other sites More sharing options...
albergman Posted May 18, 2023 Share Posted May 18, 2023 So Nefertiti will be driving the Bugatti Nick?? Link to comment Share on other sites More sharing options...
Noel Smith Posted May 19, 2023 Share Posted May 19, 2023 4 axis milling machine as well as the 3D printing machine. Busy man Nick! Lots of tech to get to grips with. Next thing we will hear is that you have a laser machine! Had lots of fun using one when I worked at a high school just before retiring. It used a 2D cad program named 2D design by a company named Techsoft who are based up in your neck of the woods in North Wales. If you don' t know them already they have a lot of interesting machines and software on their website. Their target is schools and colleges in the main, but a lot of their stuff looks very adaptable.

nick Posted May 19, 2023 Author Share Posted May 19, 2023 I’m getting the hang of this now. I still need to refine my cutting speeds a bit, but pretty happy with this. I’m just drawing all the clocks and switches etc to 3D print. @Noel this machine has a laser as well, only low power, but still useful.

nick Posted May 19, 2023 Author Share Posted May 19, 2023 Starting to get a bit more interesting now... The switches have three subtly different types it turns out Nick 2 Link to comment Share on other sites More sharing options...
nick Posted May 20, 2023 Author Share Posted May 20, 2023 Pressing on with all the Instrument Panel Hardware. As usual, I underestimated the complexity of this, so I treated myself to a couple of renders... 4 Link to comment Share on other sites More sharing options...

These ones are Air Ministry but I know what you mean. There’s a back story about the (well funded) Bentley boys buying them all up so there’s none left for the aircraft restorers who actually need them for certification apparently. 1 Link to comment Share on other sites More sharing options...
nick Posted May 21, 2023 Author Share Posted May 21, 2023 Printed nicely, some of the clearances are a bit tight, but a good start. its all a bit fragile though! stay tuned! 3 Link to comment Share on other sites More sharing options...
