Popular Post neilkirby Posted July 29, 2022 Popular Post Share Posted July 29, 2022 (edited) Hi, For some time I have been designing my own SDJR stuff, that I have posted sporadically of various parts of RMWeb. I was making what I thought was good progress when last october my Elegoo Saturn decided to stop working correctly. Months of frustration and wasted resin followed, and the machine nearly went out the window a couple of times, but I have now started successfully printing again. Below are two of my most recent prints, a rivetted version of the Johnson tender top which I designed last year, this is to be fitted to the Bachmann model, so that I can better portray the SDJR 'Armstrong' 4Fs 44557-44561: 2nd is my latest model that I did a couple of weeks ago . This is my take on the Wells no.9 brake van, the chassis is pure conjecture seeing as only the body survives, and there are no drawing that I am aware of: Another stalled project that I am hoping to get going is models of the S&D Sentinels, and Joyce as shown below from when the printer was working last year. I think I now have a viable chassis design to go under them, I have printed to prototypes and just have to assemble them to see if they work!: I have other things on the go including various types of S&D brake vans and 2 road vans, and a G9BS boiler to fit the Bachmann 7f. I am currently at work and may post more pictures when back home. Regards, Neil Edited September 27, 2022 by neilkirby typo 23 1 8 Link to post Share on other sites More sharing options...
stevel Posted July 30, 2022 Share Posted July 30, 2022 Hi Neil some very clean prints you have there, can you share what the issue was for you failures, I am drawing and printing most of my rolling stock and have had some issues myself, which some considerable time to sort out. 1 Link to post Share on other sites More sharing options...

neilkirby Posted September 27, 2022 Author Share Posted September 27, 2022 (edited) Something else I have tried on a whim. A lattice post signal based on an LSWR example but not really dimensioned, other than by eye, just to see if it would print. The lattices are ridiculessly fine, being .2mm x .15mm thick! but still they printed. There is a small 'wobble' about 30mm up from the base, but that could be down to me handling it before it was cured. But not bad for the first test print I will try another one , but will put a frame around the lower half so I can get it into the curing machine without touching it, and will see if that comes out any better Edited September 27, 2022 by neilkirby 8 7 3 Link to post Share on other sites More sharing options...

Hi Steve, My problems started when a small hole in the fep damaged the screen. I got a replacement and swapped it out. Afterwards, I could not get a decent print, I was getting failures every time, with the prints breaking away from the supports. I tried increasing the lift height and reducing the lift speed to try and stop that happening, I also slowly increased my exposure time from around 2.5 secs up to 4+ before I could get it to print at all. Above this time I could get a print but the parts looked awful. I eventually noticed that the 'light off delay' didn't seem so be happening. Investigation revealed that this (rather illogically to my mind) starts from the end of the previous exposure rather than from when the build plate gets all the way down. So the increased lift and reduced speed left me without any effective delay, which meant that the exposure starts while the resin is still moving, causing partially exposed resin to flow to the edges outside the print. I now know this is called blooming, However this is not the whole story. Just before I noticed the lack of delay I saw a really good deal on a Mars 3 Pro ands ordered this. This has printed faultlessly since day 1 with zero fails. So all my recent stuff has been from this. My Saturn 'kind of works' but was always very temperamental and I was not really happy with it before screen swap as I always had a high fail rate, plus I see no good reason why a change of screen should make it so much worse. The upshot is that I now have a Saturn shaped lemon next to the new Mars in my workshop! For the moment am just happy to be getting decent prints on the Mars, once the memory of the frustrating months dissipates I will try again to get the Saturn sorted out.

neilkirby Posted October 3, 2022 Author Share Posted October 3, 2022 (edited) Just a short update showing progress with the chassis for the Sentinel. The gearing works fine, I just need to wire in the pickups and give it a trial run: I also printed off a boiler I drew up last year, to to convert the Bachmann 7f in to the 1925 batch. This is the second attempt, the first on I tried printing with the chimney and dome in place but that did not work well, so I have split them off to print separately. The Chimney came out perfect and fits well. But as you can see in th picture, the dome failed on the very thin edge where it would meet the boiler: I will try another dome tonight, but maybe slightly thicken up that edge first, I will also do another backhead as it looks like I chose just the wrong angle so it shows stepping.

RMweb Gold simonmcp Posted October 3, 2022 RMweb Gold Share Posted October 3, 2022 Your boiler and firebox looks superb, absolutely no visible lines at all. Hope your backhead comes out as good when you reprint it. Link to post Share on other sites More sharing options...

neilkirby Posted October 22, 2022 Author Share Posted October 22, 2022 (edited) Another print, but not S&D, or even 4mm this time. 30 odd years ago I half built a Vulcan 7mm Dean goods. This never got completed as I managed to badly damage a major part and also a number of the tender brake castings were shorts. Below is some replacements for these Edited October 24, 2022 by neilkirby 5 Link to post Share on other sites More sharing options...

neilkirby Posted January 19, 2023 Author Share Posted January 19, 2023 Over Christmas I built 3 Chivers Finelines kits, 2x Diag.1771 (Tunny) and 1x Diag.1773 (Ling) On one I managed to break a whitemetal buffer. I had been using 'A Pictorial History of Southern Wagons' vols 3 and 4 for diagrams and pictures and had noticed that one of these has a very detailed drawing of the buffers needed, So after an hour on the Cad software I had them drawn up, and last night I started the first print this year the results are below , along with a vacuum pipe designed for the Tunny which isn't in the kit: I have got to say apart from breaking one of the vacpipes while removing it from the supports I am really happy with these.

neilkirby Posted March 23, 2023 Author Share Posted March 23, 2023 (edited) Latest 3d print, Large boiler for the Bachmann 7f. There's a little work still to do to get the rear of the firebox to clear the back of the motor, but the fit is pretty good now: **Edit** The smoke box door is now a seperate part, so the layering visible below is not on the latest version. Also a bit of a fail with a Lswr Lattice post signal, based on the up signal in Radstock yard. My usual mistake of going too fine rather than practical. I will have to thicken up the ladder, platform and telegraph supports. Edited April 3, 2023 by neilkirby 15 3 1 Link to post Share on other sites More sharing options...
