Two inches in diameter on the wonderful set of Paddington drawings we collected today for buffer heads. Wow and what a set. I got to sheet 6 and had to have a rest. Dear Ron from the Oxford club even included a sheet by sheet list and a copy of British Railways Illustrated vol 2 no 6 August September 1993 which has eight pages devoted to our little dears. Called The Odd One Out...The strange case of the 1500's and starts with a photo of the USA tank one of which lurks on the Bluebell, I saw her during the Summer!!!
Katie enjoyed her 00 gauge modelling and the way she arranged the rocks on her Diorama gives me hope for small bolts inside a Rob Roy smokebox. On 00 nights we can now call ourselves Pendon modellers. Yes the lovely Museum has a web site. No the plastic weld has not gone to my head?

Hi DAVID--------- next time you go to Pendon ask for Mr. Martin Parsons-------he's my Brother-in-Law....tell him you're the guy I met on Didcot Station recently.....http://www.amazon.co.uk/Ill-Take-That-One-Dispelling/dp/1901292037 -------------------- www.amazon.co.uk/Ill-Take-That-One-Too/dp/0954722957

Another book you can get that has a 1508 on the front cover is The Pannier Papers No 6 and has some lovely photos of the class. At £11.95 a nice publication from Irwell Press. ISBN 978-1-906919-57-3. You have to Wade past the 1366 class first. (Well they did do the Weymouth branch and I spent my youth driving Keith Wilson's model most weekends!!! Finding they have a power classification of 4F shows there power. David.

Ok, I'll admit it, I'm jealous of those plans, but too tight to flash out on them myself. If I can find a set for a reasonable price I'll have them but they're so expensive.

You look after them during the first three weekdays and every second friday, and they stay at mine for the first two weekends of the month so I can take them to the park?

Sounds like a plan.... sorry, couldn't resist that. But seriously, I would only need them to make the models of the parts. The boiler won't scale so that's of no interest besides the overall dimensions. I'd be happy to share them while we're building and you could have them when we're done. By that time I'll have a fully documented metric version in 3D CAD so I won't need them.

I'm wondering what the legalities are behind redrawing and re-scaling plans. Do the original copyrights apply, or are they considered different enough that they're new work?

To be honest, the whole issue of copyright when a design is scaled from full size is debatable. You could argue that you can't copyright Paddington drawings because it's just a scaled 1501. Who knows. I would think it's a bit of a grey area. The closer to the original, the weaker the argument that it's your work. If someone scaled something I'd designed and claimed it as their own then I'd say that wasn't their design.

I hope Mr Churchward won't be chasing me over The Bear's copyright LoL !---------- However I could claim some copy regarding my time put in to do research, scale down and produce plans in 5" gauge I suppose ??

i dont think the GOM will be worrying too much as very much deceased! if he were still around i think he'ed be very chuffed as he had a soft spot for No.111, and was upset when Collett scrapped it. he had a workshop at Newbarn with quite a large lathe installed and if around today might have made a miniature No.111 for his local club track! he built one of the first steam cars pre 1900 with a miniature style steam loco fitted - it still survives and is still in running condition. the only other CME who had a 'model engineering' type workshop was Col Lawson Billinton last CME of the LBSCR (and built a miniature version of his own K class loco now owned by station steam ex Oakhill collection). Marsh's assistant Basil Field was also a keen model engineer. cheers, julian

I love that fact that these locomotives live on even when their creator passes away, not many other things are like that. That's another part of the appeal of building SPEEDY, I dearly hope it will become a family heirloom.

Not too many pictures for this update, but I do have one screenshot: Making CAD drawings of the frames is coming along, I'm trying to put in all the additional holes left off the frame drawings so I can put them all in at once. I think I've found about 75%, but there are a whole bunch that are still eluding me, such as the gear frame bracket support holes and the tank support holes. In non virtual reality, I've made up six temporary spacers from thick walled tube and three blocks that tightly fit inside the hornblock jaws ready for erecting the frames. I've also made a start roughing out the axle boxes to size.

Hi Rob, Just a couple of things to note. I don't think you can have those buffer beam holes there if you're going to fit gussets like the real thing. I've extended the bracket on the rear to the full height of the buffer an added more fixing holes for that. You could do something similar but allow for the gusset at the same time. I'm not sure what can be done at the front. You'll have to look at whether you can tap into the back of the gusset. That's given me an idea for mine. I reckon I could live with a thicker than scale gusset flange on the frame side and just tap into that. You'll also find that the position of the bush for the valve gear is in a slightly different place if you're going to use Don Ashton's valve gear arrangement. I've also moved the pivot points for the brake hangers because I didn't think the angle of those looked right. You might want to model those and see what you think. Speedy's plans on the hangers and brake blocks are nothing like 1501. The pivot on the brake block is the other way round ie the tongue and slot are reversed. I'm yet to model that. Be sure to mark the axleboxes and their matching horns, it's easy to lose track of which way they all go. I'd also make sure that you hold the axlebox against the front of each horn slot, don't assume the hole will be in the middle of each one. Take a look at my Album here and let me know if you'd like to borrow the jig I made for holding the axleboxes in the lathe. You're more than welcome to do that if it would help.

On the big plans there are 9 holes for bolts for the gusset castings and wonderfully makes the more to scale version easier. Flat plates of different sizes for the buffer beam and no need to spend hours cutting the 4 slots for the frame in angles as per Titch, Rob Roy etc!!!
Though the absence of leaf springs worries me?
David. Now I am going to paint the ceiling.

David. Now I am going to paint the ceiling. I wouldn't worry about the leaf springs, on 1501 you can't really see them. Take a look at my album and you'll see what I mean. It's a nice detail to add if you can be bothered but it's a lot of work that isn't really going to make much difference to the final locomotive in my opinion.

The more you replicate original, full size items the more you'll inherit any difficulties, problems etc. that they contain, only more so due to your loco's reduced size and lack of accessibility.....Working leaf springs are a very good case in point............When "Weighing" a loco it's a job done standing down in the pit, spanners etc. to hand working on grease-covered parts..........At least with coil springs you can access the adjuster nuts fairly readily via a socket, extension and t-bar..........

Hello chaps!
With regards to the buffer beam angle bracket holes, unfortunately I already have them drilled in my frames as I originally made them with the old style buffer beams. The castings for the gussets are far too thin to drill and tap, so my thoughts were to use countersunk screws instead from the outside of the frame (similar to LBSC's original design), and then fix the gusset over those, most likely through from the buffer beam either with the buffer stock mounting bolts, or if those are in the wrong place, perhaps with some rivets. I can then add some dummy rivets on frame side of the gusset to at least make it look right.
I had also thought about perhaps soft soldering them in place, so that they're easily removable should the frames need to be disassembled. Thoughts and opinions on that method?
I hadn't realised that Don's modifications moved that bush, which is a shame, as I had already drilled that one too. Will have to work out how to get around that one. I suppose I could always make it more prototypical and move the bush to the gear frame instead, and use the frame hole for clearance only.
That's very kind of you Roger, I have been fretting over how to get the axleboxes and their holes accurate now that my hornblock jaws match. Would the fact that I'm using imperial axleboxes and yours are metric affect the jig/fixture?
I'd reached pretty much the same conclusion with the leaf springs. I looked at the photos and realised they weren't very prominent, so I think I'll stick with coil springs.
Cheers,
Rob
