    The venerable Bentley Blower in 1/12th

    Hi everyone, I’m new to the forum and would like to share some of the CAD/CAM work I have been doing to try and make something of the ancient Airfix kit Over the last year or so.
    some are CAD drawings I’ve done, renders of the drawings and finally actual real-world parts 3D printed and CNC Machined, hopefully you can tell which is which!
















    thanks for looking and the warm welcome.

            Excellent work Nick. Are the wire wheels one piece prints? The dash clocks look superb.

                No its a multi-part jig system I have developed using 3D printed hubs and rims combined with proper wire spokes with 3D printed nipples. The rim has an integral jig that holds the hub and also has a threading guide for the spokes.

                  Very impressive. A glimpse into the future. All this technical stuff is way beyond me though.

                    That is fantastic Nick. Very clever, yet extremely easy to follow. It must be a marketable proposition, especially if ported over to motorcycles……this could well be the future of aftermarket add one right there…..

                      Yes I've already started that, not sure what the forum rules are about self promotion so I wont mention the name, but I do have a micro business selling this stuff. Not the Bentley yet, but Alfa wheels and a few other things.

                        This project has sprung back into life because I ordered an amazing CNC machine on kickstarter early last year and have been eagerly waiting for it to arrive.

                        Anyway, it's here now finally and is even better than I had hoped.



                        It opens up all sorts of possibilities for things I can't do with my 3D printers, such as engine turning, laser cutting and 4th axis milling, heres a 4 axis test piece that came off it that I made with some sycamore I had in the workshop.




                        I'm also toying with dies to make louvres (like Bentley Bonnets for example) and had some success cutting aluminium with a resin printed die set I made, believe it or not. This CNC machine will let me make the new dies in brass or ali, will be better again and last.

                        Heres a test piece, I made using resin printed dies



                        Crazily, the soft resin is able to shear the aluminium to cut the slots in the louvres!



                        The dies don't last though, mainly because I foolishly printed the locating rods and they shear off eventually. If I did it again, I would use steel rods and just print holes in the dies instead of the rods..



                        The thing is, it does seem to work though, so I'm going to have a crack at making bonnet panels next. I can CNC cut the panel outline shapes in ali, with some kind of locating tabs that will pick up on the forming dies.

                        Watch this space :smiling3:

                        I'm still new here, so if this stuff isn't of interest I won't be offended, so just let me know and I'll shut up.

                        Regards

                        Nick

                          My technological abilities dont stretch much past using a petrol pump its all over my head after that but that dosnt make what your posting any less interesting so keep it coming :thumb2:

                            Well I'm interested. carry on sir!
                            I love that louvre idea- who'd have thought it!
                            how thin is the ally?
                            what is your printer and which resin are you using? I have a Mars 2 and elegoo standard resin (although I find it a bit brittle)
