sem34090 Posted April 12, 2018 Share Posted April 12, 2018 Nice! I'm glad my idea worked, even though it looks as if you couldn't use the CAD I sent you. 1 Link to comment Share on other sites More sharing options...
Shadow Posted April 12, 2018 Share Posted April 12, 2018 Will these do? IMG_20180412_201924601.jpg IMG_20180412_203028790.jpg Can you do some of those 20p things for me too please. Link to comment Share on other sites More sharing options...
cornamuse Posted April 12, 2018 Share Posted April 12, 2018 No worries at all. I'll get them assembled and stick them in the post to you tomorrow if you give me your address in PM. I'll attempt to cut some motion too, but can't promise it'll be any use. Wow amazing! I have tried to make my files for my 7mm coach work in 4mm... but the cutter isn't happy at the 0.5mm it needs to be. Would your laser cutter do it? Can it read silhouette files?

I don't know what file format your Silhouette works with but I can use DXF files? The beading on the end of my 4mm Stroudley coaches (see my layout thread in this sub-forum) are drawn at 0.5mm - they actually come out at 0.3mm due to the 0.2mm width of the laser beam. What material are you cutting? The laser cutter doesn't work with plasticard... Edited April 12, 2018 by Skinnylinny Link to comment Share on other sites More sharing options...

I have seen the 7mm card model; it's really very special: http://www.rmweb.co.uk/community/index.php?/topic/90804-gainford-spa/?p=1605770. I'm cutting card- and could maybe make the files PDF if that helps? Likewise available to anyone else on here.. not much use to me at that scale! A scale drawing would be welcome, whether or not it can be laser cut in 4mm. These are what we're talking about: Link to comment Share on other sites More sharing options...
Skinnylinny Posted April 12, 2018 Share Posted April 12, 2018 The only things I can really work with are SVG and DXF I'm afraid. I don't know if the SIlhouette software will output in either of those formats? Meanwhile, I've had an attempt at some rods for Derwent too - they're not very strong but they might last a few laps. If they work, I could see about using the laser cutter to cut masks to allow me to etch rods for a longer-lasting model in the future. 2 Link to comment Share on other sites More sharing options...

And translated from 'Saarf Lundunn': How much would you charge, good sir, for a four-millimetre scaled version of that fine model? it might scale up roof and under-frame would be your problem I had thought of trying one to offer as a part of T project but thought it may be to close to a Jesuit mission however at the moment the laser is poorly so would not be for a week or two for info it is based on the Royal coach that ended up on the KESR as to charging I would expect a local worthy cause to have a couple of quid in their coffers ( Hospice or food bank) a sheet of ply is a <£4 the electric is pennies the files drawn but helping someone down is priceless Nick 3 Link to comment Share on other sites More sharing options...
sem34090 Posted April 13, 2018 Share Posted April 13, 2018 That would be very good of you Sir, and a noble gesture to boot. I would be willing to pop a few quid (maybe more than a few) into a local charity, and that would be a very good incentive to do so! 3 Link to comment Share on other sites More sharing options...

Devo63 Posted April 13, 2018 Share Posted April 13, 2018 (edited) MRC published seven plans in the late 60's of early Parliamentary carriages which may be suitable for a quick scratch build. Unfortunately the attached scans have come out the wrong size (experimenting with a new scanner) but they do have a scale rule under the plans. Edit - just noticed the last one doesn't have the scale. Dave R. Edited April 13, 2018 by Devo63 6 Link to comment Share on other sites More sharing options...

If they work, I could see about using the laser cutter to cut masks to allow me to etch rods for a longer-lasting model in the future. Now this sort of thing, especially the wheel centre masks, is where using new technologies starts to become really interesting. Link to comment Share on other sites More sharing options...
RMweb Premium Compound2632 Posted April 13, 2018 RMweb Premium Share Posted April 13, 2018 Beware the Airfix Rocket - it must be nearer H0 than 00 as the boiler has to fit between the back-to-back of the driving wheels. 4mm scale carriages may dwarf it. Some brilliant models coming out of the woodwork (yes!) here - marriage of the earliest prototypes and the latest technologies. 1 Link to comment Share on other sites More sharing options...
Edwardian Posted April 13, 2018 Author Share Posted April 13, 2018 Haven't seen on set of driving wheels since I put them on the scanner! Or the packet with the axles! What am I doing!!!! Link to comment Share on other sites More sharing options...
RMweb Premium Andy Hayter Posted April 13, 2018 RMweb Premium Share Posted April 13, 2018 You are suffering from modellers' amnesia. If I had £1 for every time I could not find a kit, a set of wheels, a set of couplings etc., I could afford for someone else to build my models and losing bits would be their problem! 2 Link to comment Share on other sites More sharing options...

sem34090 Posted April 13, 2018 Share Posted April 13, 2018 I meant to ask, how hard was it to remove the backhead piece to access the hollow inside the boiler? Link to comment Share on other sites More sharing options...
Edwardian Posted April 13, 2018 Author Share Posted April 13, 2018 (edited) I meant to ask, how hard was it to remove the backhead piece to access the hollow inside the boiler? Not hard, I just inserted clippers and clipped it off. Fitting it will be a challenge given the cylinders, but we'll manage. The coal tender axle boxes do not exactly align with the motor bogie axles. I assume your arrangement is correct and the motor bogie w/b is fractionally off; you did not have the motor-bogie when you designed it. This might be a future refinement. As I mentioned, the material probably isn't up to very fine surface detail like the name and number, but it sanded up well, using fairly gentle lady's nail abrasive sticks. Having applied ink to show the level of surface detail better for photographs, I realised that the polyamide takes acrylic paint well, and I think that the assumption that I need to undercoat might be wrong. It will save some time if I don't. I think that there is scope to add a lot of fine detail, including rivets, that necessarily had to be left off the print, but given the time restraints, I do not propose to 'super-detail' it; I'll just be grateful if I can get it to run! Now, where did I put that wretched wheel set?!? Edited April 13, 2018 by Edwardian 5 Link to comment Share on other sites More sharing options...
