Michael,

I not up to speed on your point making project.? What material will your point bases be made from?

I have uploaded a fresh drawing of the points I am currently working on. It can be found in my folder:


The file name is points-N5-76in-ME83a-1.pdf. It should print out full size on A4 paper.

The points are designed to use Micro Engineering code 83 rail which scales out to 45lb/yd, although the head is a bit narrow. They use a #5 frog and have blades 6'4" long. All feedback is greatly appreciated.

My next set of points will have a #6 frog and will include fishplates. Who knows, I may even include bolts and spikes.

Regards,

Michael Milway

Just to let the group know I will be waving the 0-14 flag tomorrow with The Brickworks at the Dorset Narrow Gauge Model Railway Open Day at Colehill Memorial Hall, Cannon Hill Road, Colehill, Wimborne BH21 2LR from 10.30 until 3.30. Entrance just ?3, families ?4. At least 8 layouts of various scales/gauges with several demonstrations plus support from the 009 Society Sales Stand and the 7mm NGA Secondhand Sales. Hope to see some of you there.

Regards

Arthur

Hello Micheal,

Today is the 10th birthday of the O14 group. Technically the group was started by Mark K in October 2004 and I joined a couple of weeks later, but 10 years ago today several members joined and the first post was made.

O14 will probably always be a quite niche of the model railway world but I would like to think we have all played a part in gaining a degree of acceptance and encouraging kit suppliers to accommodate O14.

This group may be a bit quiet at times but when it bursts into life I feel we always have useful and entertaining discussions. We had some problems with the group website which meant very few updates over the last couple of years but thanks to Steve we are now back in control so if anyone has new contributions they would be very welcome.

Best Regards to all
John

Hi Michael,

Re the joints in the stock rail. I suspect (purely based on observation) that switches were produced as a pair of planed blades and stock rails which, together with crossings, are assembled on site using plain rail to join them up. Hence the joints near the hinge - and also just beyond the blades. I too have seen photos with the joints opposite the hinge which as you say this was probably to aid transport and lifting - especially appropriate for the WW1 field railways. However, I suspect this is a much weaker arrangement. In model form I think all these joints should be cosmetic, i.e. use continuous rail with fishplates added and a notch in the rail head if you are really pernickity like me.

As to Sn3 I used it very successfully for the hidden track (all 15m of it) of the PLR at it's recent outing. I believe others have also used points - perhaps with some filing of the check rails.

Finally I'm sure many would welcome a to scale plan. If you are willing we could host it on the main group website with supporting info as per your original post - send me the info direct if you are OK with this.

Regards
John

Thanks for your kind words John.

I have seen lots of points with the joints in the stock rails as you describe. My personal preference is not to have any joints in the stock rail as this is the strongest configuration. If I need a joint then I would prefer it halfway between the blade and the frog to give the best staggered joint.

I have seen light weight sets of points that had joints in the stock rails opposite the blade hinges. This allowed the set to be split into two parts for easier transport and lifting. The photo on page 3 and the engraving on page 4 of the WDLR Album shows a set of points that can be split into three sections. this would make movement and assembly in the field much easier at the expense of long term stability (not required in this case).

The last set of points I worked on had a joint in the stock rail part way along the checkrail - an awkward position but dictated by the existing formation before that set was built in situ.

0.3mm gauge widening would certainly assist the passage of longer wheelbase locomotives. 0.3mm scales out to 13mm or 1/2" in full size. Definitely not an excessive amount for a model or a prototype. I have heard of much more severe gauge widening on a very sharp curve on a sugar cane railway.

This raises the question of the use of Sn3 track for modelling 014. It has a design gauge of 14.3mm. Does anyone use it for plain track?

In my previous post I neglected to mention that I use 3 way planed blades from

I use the 11ft code 83 ones. I am also looking at using their etched spikes,

The longer, .015”, spikes look dead on for a scale 5/8” spike which should be adequate for most 2ft gauge track. However, they are very fiddly.

Finally, the plan drawing of my points in the files section is not to scale. If people are interested I will publish a fresh drawing which is to scale and has both left and right hand points.

Michael Milway

Hi Michael

Well done for all this prototype work and producing a superb design which I think will be useful to many. I remember our founder member Mark sending me several photos of the Illawarra trackwork some years ago and I would have dearly loved to have visited it when we were down under last year.

Some suggestions if I may:

1 There is usually a fishplated joint in the stockrails soon after the hinge - obviously cosmetic for us modellers.

2 I have found a bit of gauge widening (0.3mm ish) added during construction in the curve between the hinge and crossing/frog helps with longer wheelbase locos. The crossing itself is best kept to gauge.

Best Regards
John

After reading all the replies to my original post and measuring up every set of points at the Illawarra Light Railway Museum, I have come to the following conclusion:
"They made it all up as they went along"
I have not been able to find any Constancy in checkrail length, wingrail lengths, blade length or anything else. Not that I would claim that the points at the ILRMS represent a reasonable sample of the real world.

I have designed a set of #5 points and placed some drawings of them in my folder in the files section:


I believe the design is quite reasonable. Indeed I would happily run real trains over a full size set of these points. The following design criteria that I used may be of interest to others on here. I have used imperial? units as I am looking at points designed pre-metricification and the numbers tend to make more sense:

The points are designed for Model Engineering code 83 rail which scales out to about 45lb/yd.

Checkrail length = 6ft; spans 3 sleepers for stability
Checkrail is centred on the nose of the frog

Wing rail length = 3ft from the nose of the frog

Trailing end (Vee) part of frog is = 4ft; allows for fishplates

Leading end of frog = 3ft from the nose; matches check rails and ensures the track is straight for the whole length of the checkrail.

Sleepers are 8" x 4". This is a reasonable size and I got some H0 scale wood that measures this size in 7mm scale. Cut down standard gauge sleepers are also a sensible choice.

One sleeper is placed under the nose of the frog, Other sleepers under the frog are spaced at 2 ft centres.
Sleepers under the blades are spaced at 2ft centres.

The blade pivot is on the centre of one sleeper.

Blades are 6'4" long so the toe end is level with the edge of the first sleeper (actual geometry moves this around slightly)

Heel offset is 4". This matches the heel blocks that we got from Victoria sugar Mill in Queensland.

Slide chairs are used on 3 sleepers and an solid steel plate is placed under the pivot.

The blade angle should be about 3 to 4 times the frog angle. The above blade length and offset gives a blade angle of about 1:19 which is within the range for both #5 and #6 frogs.

Blade opening is 3.4" = 87mm = 2mm model size. This is within the range of blade openings at the ILRMS and just happens to be the thickness of a paddlepop stick.

The distance between the end of the blades and the start of the frog has been set to give a smooth curve. This maximizes the radius of the closure rail. Changing this distance results in the curved closure rail having a sharp curve and a straight section.

Sleeper spacing for wooden sleepers can be 2'6" except under the frog and blades.

I had a lot of fun doing the drawing in 3D, especially extruding the rails. Life is too short to add all the bolts, spikes and fishplates. Maybe next time.

I hope everybody enjoys my drawings and I look forward to any comments/improvements that are offered.

Regards,
Michael Milway.

Hi Marc. This sounds promising. Will the specific carriage bodies at Hulme End be in the range? They had been bashed about with new 'shed doors' and missing panelling so I thought it might be easier for me to scratch build. I was going to start them around Christmas time, but if you are going to have the right bodies all done then I will wait and do a 'kit bash'.
