91 forum posts 6 photos | Just looking at my posting, I see that I have missed mentioning a potential "Grey area". Some 3Dviewers, such as Solidworks eDrawings viewer allow you to measure dimensions directly off the model. So some care would be needed when deciding how the models are to be displayed online. Ron |

183 forum posts 20 photos | Good morning all, What an interesting thread. I cannot add to the copyrights issue except to say in the past many of the early LBSC designs, the drawings of which, were either drawn or LBSC's originals redrawn by Roy Donaldson and marketed by Donaldson and Piper, which I seem to think may have been sold on to the then A J Reeves; I have a set of Jennie Deans drawings on which the Donaldson and Piper reference has been lined through and the A J Reeves reference applied. Interestingly, Kennions redrew many of the LBSC designs, which may have been a result of a copyright issue. I have here copies for Molly drawn by both the then publisher Percival Marshall's own tracer and Kennions. In view of the impending anniversary of the old fella's death there may be an opportunity for the present Model Engineer to publish a special LBSC edition. Regards' Bob |

196 forum posts 2 photos | I assume you know of LBSC's book 'Shop, Shed and Road'? It contains some photos of some of his designs. It does not contain build instructions for any complete locos, but it does deal with his standard fittings and approach to design and construction, including: injectors, pumps, gauges, whistles, safety valves, releif valves and snifting valves, motion work, lubricators, North-Eastern compounds and Mini-steam engines. First published in 1929, the version I have is the 1969 version edited by the late Martin Evans.
There is also the book 'MONA: A simple 0-6-2 tank engine' by LBSC. That has drawings and build instructions for MONA in 3&1/2 and 1&1/4 inch versions.
The Gauge 1 Model Railway Association members are familiar with LBSC's gauge 1 designs www.g1mra.com You may also be interested in the copyright position stated here: http://www.john-tom.com/html/LBSCEngines.html What would be of tremendous interest to me would be new sets of drawings, updated to reflect modern safety standards (boilers etc), and dimensioned primarily in metric units. If you want the designs to live on, that's the way to go, IMHO. Your CAD approach is the right one, I think, especially as it would allow easy transfer of the drawings from CAD to CAM and CNC with little effort.

but Dean is from the USofA, that last bastion of Imperial measurements Sorry, I'll take the dog out That's alright sir, I've put them both out this morning. My male was a bit more stubborn than the female was. I don't think it would be TOO much of a problem to convert to metric, but I haven't the slightest idea on how the newer boiler designs would be done. Then again, I have a love hate with metric- it makes a lot more sense at times to use (especially concerning fasteners) but then at others I catch myself thinking "what the heck is this? Why can't XYZ in imperial have a nice round number in metric?!?" I honestly am still scratching my head a little on how I am going to proceed with this. I'm hoping that maybe an established business in the U.K. in the world of model engineering would want to sell the designs- I really honestly don't care too terribly much about the money. For what it's worth my machines are imperial. Curiously I own an American live steam pioneer's (Francis Moseley) personal milling machine. The same machine he invented the power feed for originally, as well as the DRO- the items the fine folks at Servo Products would go on to produce. Literally power feed number one that ever existed (the electric type that bolts to the table) was made on and for my milling machine in the previous owners hands. I joked once I only need Curly's Myford 7 and I'd have a machine tool museum. If a club has a lot of the material for the models of a certain gauge (if not all) I'd do it for them no problem, I would actually love to see clubs maintaining this material to enjoy. If there are any typos in here I'm sorry, this was done on an iPhone.

![]() 221 forum posts | I've actually seen the 2 1/2" gauge association website before. The fact they have Curly's "Ayesha" from the boiler wars almost makes them the bearers of the holy grail- at least in the live steam context. I'm curious how incomplete some of these drawings are- if by incomplete they mean it's the articles with out proper drafts (draughts? I need to put my computer's spell check on proper English) but it has the little bits from the magazine I'm sure I could manage. Granted, I might need drawings of the prototype or some input on finishing up the CAD files. Being the perfectionist I am there is nothing that makes me more uneasy than having to guess at what I am drafting because the originals are missing dimensions. Especially with Curly's work. When I'm at my computer again I'll cite some examples that made me wonder a bit about his drafts.

842 forum posts 56 photos | Dean; Just a comment from a northern neighbour of yours. These are just thoughts, and the only arguing about them I'll do is in person over a pint of beer. My Tich was built in inch measurements, but when moving about NZ and Europe, most everything was metric, as was a lathe I picked up while living in NL. I converted, it was tough at the first, but became really easy. Now, I convert inch plans to metric before machining, even if I'm doing CNC, as, for me, metric is just so much easier. I'm surprised how Model Engineer has adopted metric, it's no where near 100%, but it was about 0% a decade or two ago. Building metric in an inch country; most all of my materials now come in inch form, but a 1/2" round bar of brass I use as 12.7mm, etc, etc. I can remember trying to buy a BA tap when living in NL, and I have the same issue back here. Metric is pretty universal; yes there are some thread pitch differences in older country-specific metric tables, but it is really as close to a world standard. Kids know metric. In the USA, most of the fasteners on 3D printers are metric, as are the spools of filament. Cars are metric, etc, etc. I'd love a little CNC Sherline lathe, but the one major item for me is that the fasteners are NOT metric, so it means yet another bunch of taps/dies/spare screws; like the Whitworth and BA screws on two of my British made machine tools, it is a hassle I don't want. What you choose to do is TOTALLY up to you, and the inch (english, imperial, whatever you wish to call it) system works very well, but the world seems to be adopting metric, so your re-drawing to metric may prove to be more popular in the future, and maybe the "defacto" go-to for accurate LBSC drawings. (BTW, should anyone complain, right now we have a partial solar eclipse going on, so, rather than fire back vitrol, just shake your head at the poor Canadian, and blame the "Eclipse Madness"

The 2 1/2" gauge association had Ayesha on show at The Bristol Model Engineering show last weekend. The show theme was the LBSC 50th anniversary: More unusually, Greenly's rival Loco was also on show, on a different stand:

![]() 25215 forum posts 3105 photos 1 articles | Dean, can I ask what experience you have in building and designing steam locos? My reason for asking is that by adding in the bits LBSC left out, correcting errors, maybe converting to metric then testing them on a Solidworks model is one thing but you will in effect be drawing an untested design which may not work in the real world or be as efficient as it could be. As an example there is another chap who has redrawn a lot of small engines and a few locos and traction engines in cad, converting to metric as he does so. It all goes together on his cad assemblies but in some cases what is drawn just cannot be built or has some very impractical sizes, missing or hard to work out dimensions, etc. So unless an example has been built to this revised design how will anyone know it is going to work? Regarding your comment about the detail on LBSC's designs they were built to be practical to run not display case replicas and it took someone with many years of designing engines to know what could be made to work in the smaller scales and what should be left out. Had he been making 7.25" locos then I'm sure he could have counted the rivits. |

![]() 19226 forum posts 749 photos 86 articles | Dean, Diane and I think the principle fo this is great and we would be happy for you to make 3D models of any designs we have the rights to and put something like interactive 3D PDFs or similar of them this website. The problem is that it is proving almost impossible to identify which, if any, LBSC designs MTM still own the rights to; MyTimeMedia sold all its plans (except the Martin Evans plans, which MTM definitely own the rights for) to Traplet, Traplet have passed those on to Sarik Hobbies www.sarikhobbies.com/ There are also, of course, various designs Curly produced for other magazines than ME and associated Percival Marshal titles whose rights are (probably) owned elsewhere. We think it would be best to avoid publishing full drawings in CAD format, but we could host CAD models here if:
This does put the onus on you to do a bit of research on each design. I hope that helps a bit. Neil |
Russell Eberhardt | 24/08/2017 11:56:23 |
![]() 2785 forum posts 87 photos | Neil, You are confusing design rights with copyright. The plans and the "words and music" are covered by copyright which lasts a long time. However the design rights for unregistered designs are relatively short term and any rights that LBSC had will have expired by now. So anyone is allowed to copy the design but not the documentation. Surely a 3D model is just an electronic copy of the design. If drawings are created from that they are not the same as the original plans. I think you are worrying too much. Russell |
