Dear John and Stephen, many thanks to both of you for your help. Stephen, sorry I didn't find that myself.

I also discovered something else. I was getting a bit of bumping approaching the common crossing. It turns out that the C8 chairs are for outside of the rail, so assuming designed for the wing rail to run as far as the C timber, where as on my Templot plan the wing rails finish between the B and C timbers. So I have shaved the tops and on future builds will have to find some chairs suitable for the inside of the rail for the C position. I will check the D ones.

Thanks again for you help. Tom

Thats because as I understood it, Exactoscale's configuration of the common crossing differs due to production requirements of their kits. As I don't use the kits myself I follow the Templot positioning on this as I think it is more prototypical..

Once all the timbers are laid its the common crossing I fit next, with the crossover I fit both at the same time

Initially I fit the straight roads using solvent ensuring the tip is in line with the plan, by looking from all sides. Then once set I use gauges to set the turnout roads, then the special chairs.

Here is a close up of the chairs, there are enough chairs for a 1 in 5, 6, 7, 8 &10

 

Now I thread the stock rails, you can see the  two turnout roads being gauged with each other as well as the check rail chairs

I thread one of the additional switch rail chairs prior to fitting the stock rail

A close up of the additional switch chairs, there are enough chairs to make a left and right hand turnout and both can be either A, B or C switches

 

I have missed taking a photo of a bridge chair which are also used in a standard turnout, will take a photo later to show them

 

I hope this shows those of you who are either unaware or not too familiar of these items. I may use Martin Wynn's Templot plan of a Peco size turnout given a scale make over, just to show what can be achieved

 

These are much better than chopping up standard chairs, pity they are not available in 7 mm scale

John

I am just about to embark on building EM turnouts using ply sleepers and glued plastic chairs.

 

I have purchased (I think) the necessary chair mouldings - C&L mouldings supplied by the EM gauge society. The mouldings have small numbers by each chair moulding. What do these numbers relate to?

 

Thank you 

Paul

Sounds like you have some of the special chairs either for turnouts/crossings or slips. What description is on the packets?

I have packs of :

E4CH 501A - A,B and C switches

E4CH 502A - common crossing chairs

 

I also have slide, bridge and check chairs but these are not numbered and are not as bemusing!!

 

Thankyou

Easy, here is a link to the chair details. Just study the plans and the numbers become relevent

 

https://exactoscale.com/track-components/chair-positions/

 On the common crossing the center part of the 2PL chairs are missing as in the kits there is a link between the switch and stock rails. Also on some of the block chairs on both the switch and common crossing chairs need a 0.5 mm packing under them

 

Look on the check chair sprues CCL is the left hand end, CCR is the right hand end. Always looking from outside the stock rail

Dear John, you invited me to post work in progress on your thread occasionally. I would not have attempted anything like this if I hadn't worked my way through your previous builds so many thanks to you and to others that have posted helpful advice.

Please forgive the loose bits of copper. They are just temporary as I am experimenting with a different tie bar arrangement and I want to test it before the slide chairs go in.

Do feel free in posting what you like, tiebars are the bane of most folk, The 3 way turnout looks very good

 

A big heads up. Exactoscale are going to stop supplying their products directly from the end of the month, in 4 mm scale they will be available from either the EMGS of Scalefour Societies. & mm from the Scale Seven Society

Just thought I would show the new 3 bolt chair sprues which will be available very soon from C&L which will be followed quickly by a new 2 bolt sprues. Cannot remember if they are test shots or 3D prints

The new sprue will have 10 x standard chairs, 2x S1J chairs, 2 Bridge chairs plus one standard H shaped fishplate and one reinforced version

Bridge chairs still work in progress on the tool but as you can see on a standard sprue 4 extra chairs

 

873.jpeg.af1c5ad02d3b066ae6482de1d8157ba3.jpeg

 

At the other end a choice of functional fishplates

Couple of close ups

In many instances at the end of  panels (where there are 12" sleepers and at the ends of turnouts and crossings and some rail joints in between the S1J (large) chair is used. Just a larger chair for added strength at rail joins

 

On reflection I am surprised these were not included in the Exactoscale range.  They have been available in 7 mm scale for some times from Off The Rails on the Shapeways 3D printing site
