Thread: Thick walled copper tube
11/02/2019 23:44:06

Hi Keith,

I finished off a couple of Tich boilers for someone some years back and had the same problem. I just used ordinary thin wall copper tube and silver soldered bronze ferrules on the ends. One was threaded to screw into the blower valve and the other threaded 1/4 x 40 to screw into the bush in the front tube plate. You could also just silver solder the tube into the blower valve. I did that on my Helen Long boiler.

Not a good photo but you can see the blower stay at the bottom. You don't need the double threaded fitting on the smokebox end. The end of the ferrule is countersunk and the blower pipe just fits straight onto that.

Thread: 3.5" Locomtive
29/11/2018 00:53:00

Yes, definitely a Fayette but whoever built it deviated from the drawings a bit and used some Bonds castings for the trailing frame and the rear truck (the drawings call for built up items for these). The frame stretcher behind the cylinders is also a Bonds casting. Fayette is a nice loco and runs well. Hope you manage to complete it.

Thread: Ayesha 2 and bigger chaps
02/11/2018 18:42:54

I'm probably a bit biased but I get to drive LBSC's Ayesha whenever I want. It's well worn now but has no problem pulling me and heavier drivers.

LBSC was always extolling Ayesha's passenger hauling capabilities and said that he often pulled more than two passengers as well as himself. I'm sure that the old girl would still pull a couple of people given a suitable truck and some decent steel rail for adhesion.

I think of more importance than the power of the loco is having a very free running driving truck. Quite a few of us have changed to the David Hudson design with the self steering axles. These are very free running indeed, especially around curves and take very little tractive effort to pull along.

Thread: What have i got here?????
09/10/2018 12:13:45

Hi John,

I can't find anyone who sells the drawings for Green Arrow but I can let you have a copy of the articles if that would help? All the drawings are in the articles so you don't really need the full size ones anyway.

It looks like you have most of the castings and anything missing could be fabricated.

Model Engineers Laser do some parts for Green Arrow including laser cut tender bits.

You should be able to get drawings etc. for the Project from the G1 Society. I think they do a booklet for it.

Just had a look at the articles. The chassis and probably the castings are for Green Arrow but unfortunately the boiler is not. Green Arrow has a wide firebox coal fired boiler whereas yours is a shorter narrow firebox boiler either gas or spirit fired. Possibly meant for something like the Gauge 1 Project?

John

08/10/2018 21:27:07

I would say that it is the Gauge 1 2-6-2 Green Arrow by Martin Evans described in ME starting In October 1971. Not sure if anyone still does castings for it.

Thread: Convex buffer face
21/09/2018 00:35:56
Posted by Mick B1 on 20/09/2018 21:46:16:

I've never actually done this, but an experienced turner showed me a method using a pointy rod the length of the required radius located in deep dot-punches below spindle centreline on headstock and crossslide chuckside face.

You use the saddle handwheel to keep the radius rod in contact both ends, whilst traversing a tool across the workface. The saddle moves away from the chuck to generate the radius. You arrange the tool so that it reaches centre when the radius rod's parallel to the bedways.

It's fiddly, but it's simple, accurate and I've seen it work.

Edited By Mick B1 on 20/09/2018 21:49:23

That's how I do mine:

The method was described by Tim Coles in ME Issue 4277.

Thread: oscillating disc valves
03/05/2018 08:22:29

It looks to me that the cylinders are actually conventional slide valves but the valves are round instead of rectangular. LBSC used round valves on his Ayesha. The last photo shows the round valves connected to the valve rods.

The round parts that I think you are thinking are the valves are actually the port faces and the ports are curved to match the circular valve. The large central hole is the exhaust port Are you sure that these rotate? It's possible that the port discs were made separately for ease of manufacture and remain stationary once in position. I can't see a reason at the moment why they would need to rotate. Are there grooves under the port face to connect the ports to the steam ports drilled in the cylinder?

The loco may well have conventional valve gear such as Stephensons.

I would say they are definitely for the 3½" gauge Britannia by LBSC.

Thread: Trolley wheel arrangment
14/04/2018 18:14:46

If you want a really free running design for a driving truck or passenger car then look at the design by David Hudson that has self steering axles. He described the theory and construction in ME for 2003. His is by far the best design I've come across and used. Our club driving trucks and passenger cars are to his design and they are very free running.

Our club went to the Burton track some years ago and one of our members took his Hudson design driving truck. At the end of the day, we decided to see just how far it would go on it's own. It was given a good push and did a complete circuit of the Burton raised track and would have carried on if we hadn't stopped it!

I believe that Dave Noble still offers complete kits for the driving trucks as well as individual components.

I'm just about to convert my normal 4 wheel fixed axle truck to the Hudson design as at the moment it has too much drag for small 2½" gauge locos to pull around easily.

Thread: Boiler test info
09/02/2018 10:56:12

Hi Paul,

The boiler would need to be removed and also the cladding so that it can be given a visual inspection. It would then require a hydraulic test to twice normal working pressure to make sure it is sound. This assumes that you would want to run the loco at a club or anywhere in public.

You can usually tell just by looking at a boiler and the soldering whether it has been well made or not.

Thread: What Regulator type.
09/02/2018 08:51:59

For my screw down regulators I make the seat part from a bearing grade PEEK. This gives a perfect seal and the valve never seizes shut when the boiler cools down. I find the control to be very gradual and smooth unlike some of the regulators on locos I've driven where it's all or nothing!

The thread on the one for my Helen Long uses a 3/8" BSW thread and for normal running the regulator is barely cracked open, no more than 1/8 of a turn. Any more than a 1/4 turn and the opening makes no difference as the steam flow is controlled by the valve gear rather than the regulator. The pointy bit has an angle of 120°.

I added the spring to take up any backlash in the thread but found it wasn't necessary.

And yes, the tube is brass but it will probably outlive me! Copper would have been a better choice.

Thread: Steel or aluminium track
10/10/2017 00:48:58

IMHO aluminium track is absolutely dreadfull stuff! I hate it. It soon gets a very greasy film on the top that reduces adhesion to next to nothing. Give me steel track any day!The only advantage apart from cost is that it gives quieter running than steel.

Thread: Off to the races!
03/09/2017 01:04:16

Hi Dean,

As Brian says, you are setting up for a lifetimes work with this!

You will find that a few of the designs were only very briefly described in the magazines - a GA drawing and maybe a boiler drawing if you are lucky. We do have copies of most of the construction articles though if you need them.

Re Lucy Anna - we have copies of the articles in Model Maker and also the drawings.

Re Liberation - I think this is a mistake in Brian Hollingsworth's book. Certainly I can find no trace of it and the article mentioned in English Mechanics does not exist.

Re LBSCR - I think this may be the Southern Region 0-4-4T (2396) which I think is the same loco as Victoria.

Hollywood Annie is an Americanised version of Annie Boddie and was briefly covered by 4 pages in Model Engineer.

Cleopatra was covered by a single page in ME and had just a GA drawing.

Hope that helps,

John

Thread: LBSC's Designs
17/08/2017 20:08:11

Richard,

You will often find that there are more than one set of drawings for many of the LBSC designs. Kennions (as it was then) produced their own drawings as did Model Engineer. Donaldson and Piper also did them. Unfortunately, there are often quite a few differences between them!

Thread: LBSC Memorial Rally
17/08/2017 20:02:52

As it is the 50th anniversary this year of the death of LBSC, it has been decided to replace the usual Curly Bowl competition with a special commemorative rally. This will be held on Sunday September 3rd at North West Leicestershire SME from 10am.

The track is in the grounds of the Hermitage Leisure Centre (behind the 3G court), Hermitage Road, Whitwick, Coalville, Leicestershire, LE67 5BZ. The track is steel, 1250' in length, and has 2.5, 3.5, and 5 inch gauges. Everyone welcome. Refreshments will be provided. Bring your LBSC design loco for a run or just for display.

Thread: LBSC's Designs
17/08/2017 19:30:03

Hi Neil,

That's interesting. I didn't realise that ME only held the copyright for 25 years.

I would hazard a guess that quite possibly no one owns the copyright to the actual LBSC designs as I doubt anyone would have inherited them. He and Mabel had no children so there would be no family to inherit the copyright. He was very close to Mavis Harriet and she inherited several of his locos, including his own Tich and of course, Ayesha (now owned by the N25GA). but I wouldn't think he would have passed the copyright onto her.

The Association has been given quite a few sets of his original pencil drawings for his well know designs in all the gauges. I haven't had chance to go through them all yet to see exactly what we have, but off the top of my head we have the drawings for Virginia, Betty, Pamela, Iris, Petrolea, Miss Ten to Eight, Netta, and several 2½" gauge designs including Rose.

They are all in very fragile condition but I intend to scan them when time permits before they disintegrate altogether. Not an easy task as they are pencil on what looks like lining paper so the contrast is poor.

LBSC always used to say that he was a terrible draughtsman but some of his drawings are a work of art and well worth hanging on the wall. Apparently, he used to send odd drawings to his friends as a present. The drawings for Rose were given to us by a gentleman in the USA and he had acquired them from someone else etc.

We do hold copies of the drawings for virtually every 2½" gauge design that ever appeared but we do take care not to sell copies of those that we know are sold by others such as Reeves or GLR Kennions. We hold a few that I think ME have lost over the years and seem to have disappeared from sale e.g. Nigel Minor.

When Bonds of Euston Road closed they passed all their remaining castings and patterns onto us and gave us permission to use their 2½" gauge designs so I suppose you could say we now hold the copyright to all of the Bonds 2½" gauge designs.

I don't think you will have any problems unless you decide to sell copies of your CAD drawings. Then you probably will be breaking copyright, certainly in the UK.

There are several companies in the UK that sell LBSC drawings e.g. Reeves and GLR Kennions. They would probably claim that they hold the copyright to those drawings. I presume that Model Engineer magazine still hold the copyright to the majority of the LBSC designs as they were published in either Model Engineer or English Mechanics.

There is no danger of the 2½" gauge designs dissapearing as the National 2½" Gauge Association was formed to make sure that all the 2½" gauge designs, not just those by LBSC, are preserved for the future.

One of my 'to do list' items is also to produce 3D CAD drawings for all the 2½" designs, mainly to find and correct all the errors in the drawings and improve the valve gears. I've made a start but there is a long way to go!

Good luck to you on your project.

Thread: TIG welding copper boilers.
07/08/2017 03:33:34

Your biggest problem will be getting it tested if you want to use the boiler in public. The average club boiler inspector won't be qualified to test a welded copper boiler and probably won't touch it with a barge pole, especially if it is welded by a non coded welder. You are going to be looking at having it tested by a relevant professional tester at possibly considerable expense.

Good luck if you do decide to go ahead though.

John
