The diverging track and the straight through are exactly as the Exactoscale A5. The centre track is equidistant between the two tracks of the A5 at it clears the turnout. Hi Jon, Unfortunately that produces a sub-optimal tandem. Equidistant straight exits require the two V-crossings to be exactly o...

Hi Jon, We seem to be at cross-purposes. Are you saying that the first turnout in the tandem has to be an exact match to an Exactoscale A-5 turnout? In which case the second turnout will need to be something like a B-9 or B-10 to get an even spread of exit tracks (if an even spread is needed?). Or d...

I like the idea that I came to this back to front. Actually I had a track plan with a straight though and a diverging A5, but the real world track plan had a tandem at this point. The A5 curve was fixed as was the straight. Hi Jon, If the A-5 is already on a fixed alignment, I'm afraid this tandem ...

This may be a question better put in Templot Club than here (but I'm logged in now so I'll ask it anyway!) - how did you work out the second turnout had to be an A-7? Is it one of those things you just have to know , or am I missing something obvious (I usually do)? Hi David, Short answer: 1. guess...

I printed it out and found it is slightly too large (it comes out at scale 5' gauge, or 20mm) Hi Jon, When you print it from your PDF reader, it is very important to make these settings in the print dialog (which are not the default in most readers): jon_tandem3.png However, now that you have insta...

Hi Jon,

Templot can do that (it's free). For a single-sided tandem you need to start with the 2nd turnout, which in this case needs to be an A-7:




The timbering will need some final adjustments.

cheers,

Martin.

Please can someone point me to the guidance for adding proper links to a post?

Now, I am no engineer, but if Hi-nickel rail has a head profile which is incompatible with the profile of P4 wheels (i.e. too square-headed), would that not make a P4 profile wheel ride up on the root radius of its flange when the wheel is running against the rail? Hi Colin, I don't think that is v...

It's sometimes hard to work out which is top and which is bottom so I find I can only do this in a good light - usually a bright 'daylight' lamp but sometimes the genuine article. Hi Jen, Try pressing the end of the rail into a bit of Blu-Tack. It is easy to see which is the rail head in the impres...

It seems that someone was asking about 3-way tandem turnouts on a Templot demo stand at Scaleforum. The demonstrator didn't mention that Templot now includes some automated functions to create tandem turnouts. If that person is reading this, please see: http://templot.com/companion/3_way_tandem_turn...

hi Monty, Cut one of these, or one similar, into 3 sections: https://i.ebayimg.com/images/g/Do4AAOxyVLNSrnBI/s-l500.jpg https://i.ebayimg.com/images/g/3NQAAOSwXudbDPcz/s-l500.jpg Middle section goes on the fixed baseboard part, end sections give you 2 locators on the traverser/turntable part. Mechan...

DCC Concepts have just released a new system of working point rodding. Or at least I assume it's new, otherwise why have they suddenly sent me an email about it?

It looks interesting, see:

I obtained my Sundeala from Ashford Model supply centre, but it appears they are no longer trading, so not sure what to suggest. Hi Tony, Philip, Cut sizes of Sundeala available delivered from Amazon: https://www.amazon.co.uk/Sundeala-Board-Pinboard-Notice-1220mm/dp/B018IPZC8S/ I don't know how the...

but I run a Mac which gets indigestion with Templot Hi David, Here's a 1:4.5 symmetrical Y-turnout from Templot (radius 1595mm, 63"): http://85a.co.uk/forum/gallery/2/original/2_081324_390000000.png Here's the PDF file to print it: y_turnout_p4_4p5.pdf Any other size easily created. Just ask. ...

I have a stash of Copydex but a number of things put me of using it: 1. The odour 2. Questions on whether it can be and how to dilute it 3. You can't drill into it Hi Peter, 1. the smell goes away as it dries. 2. it can be diluted with water. 3. drilling the dried latex film is no problem if you sp...

From the angle at which the pictures are taken, probably not possible. I would have thought that you would need to see a section of rail end on to see the angle. Hi Terry, That was exactly my point. The only place you are going to see inclined rail end-on is on wing rails -- which is precisely the ...

so it will be very interesting to see if there are any noticeable differences in the running between the different track sections and rail profiles. Hi Tony, And interesting to see if anyone can see the visual difference. Bearing in mind that the most obvious rail ends are on check rails, which sho...

Really not sure what I'm doing ... but following your advice my set bends and knuckle bends are definitely working and I am definitely using Exactoscale chairs and definitely not using ' the proper conical press tools ' :o .... :D Hi Tim, If there is a knuckle bend in inclined rail, the head of the...

I don't need to. It is logic. A wheel with a 1 in 20 cone will touch a vertical rail on a knife edge. If both have the same inclination the contacted area is larger. Which will reduce the contact pressure and make electrical pick-up actually worse. The minimal knife edge contact has a very high con...

An interesting hypothesis Martin .... though it does beg the question as to why the narrowing is so localised? Hi Tim, That question applies equally to any other explanation -- shrinkage of plywood, expansion of rail, etc. Perhaps a section of chairs from a different batch? An interesting finding w...

Interestingly I have found a couple of areas on my track where gauge narrowing has occurred over the last 2 or three weeks that were fine before :shock: I have separated the chairs from the sleeper and re bonded to gauge and all is fine. Slightly confused as to why this might have happened with the...

but trying to reverse engineer an existing Temploted layout accurately, I have found that using X-Y co-ordinates and counting sleeper / timbers the most reliable method. Hi Tony, If you have a scanner, try taking a series of A4 rubbings from the rails, and scanning them: https://images-na.ssl-image...

One observation reading through all the above would be that designing a box diagram by committee probably gets a good result in the end - but it is not necessarily a quick process, and collateral casualties might temporarily include a few friendships! And do you number the levers left-to-right as s...
