The Scalefour track and wheel standards shows the gauge to be min of 18,83 and maximum for gauge widening, at a radius of 528mm, of + 0,22. The trouble is there is no tolerance up from the 18,83 for straight track as this is stated to be achieved using construction gauges. It seems to me that if the variability was no more than say 0,10 or even 0,15, it might be achievable. Comments? Jeff Wayne's product uses the same cast common crossing (which by design is a bit short so that it is not handed) one crossing fits both left hand and right hand turnouts and also EM and 00SF gauges. Simply 4 products can be built from 1 casting, when diamonds come in then 8 products per casting can be produced To keep this product within a budget then a few compromises have to be accepted, plus is there a market share to break even let alone make a profit ? If a P4 turnout was introduced those interested will want full length handed common crossings, which equates to 2 castings per turnout size, then you have the question of inbuilt manufacturing tolerances in keeping with P4 standards Lets run with the first few products and see how the market accepts them, 1 Link to post Share on other sites More sharing options...

Yes you can. 11 hours ago, Philou said: If the answer is 'Yes', can I make a suggestion that once all the leaflets have been used up and/or the tooling become worn, then it would be an opportunity to alter the instructions to reflect the making of the set? A Mk1 and then a Mk2 version if you will. After all, despite compromises that have to be made modelling in 00, should we not be striving to achieve as near to prototype as is practically possible? It's what most RTR loco manufacturers seem to be doing. If a set can be achieved by means of a tap of a hammer on a simple jig by those that wish to, why not? Please refer the post above by Gordon S, this really sums up my thinking very well. 2 1 Link to post Share on other sites More sharing options...
hayfield Posted April 5, 2021 Share Posted April 5, 2021 2 minutes ago, RBAGE said: My point is that the vast majority of 00 gauge modellers never consider course scale or finescale. They would consider that getting replacement wheels as an unnecessary and unexpected expense. As you say, that part of the hobby is catered for. This majority of modellers would never consider checking back to back dimension, thinking the industry will have taken care of that. Not an unreasonable assumption. If it is considered necessary for 00-FS, as some well positioned contributors assert, why is that if measurement and adjustment is not necessary? My comments are not based solely on the advice of the great and the good but that advice isout there. Anyway, this is not the place to discuss gauge standards. Apologies to Wayne. But is this product for the vast majority of modellers who are happy with what they have got, its not !!! Its designed for the modeller wanting something better than what's available, the choice is "Finescale 00 gauge" or the ability to migrate to EM gauge. Neither of these two options is designed for the vast majority of 00 modellers, many of whom are happy with "set track" in code 100. As Gordon has said its designed to move the hobby forward !! 3 4 Link to post Share on other sites More sharing options...

Hi Keith, No. But they don't claim them to be models of a prototype, or use prototype terms to describe them. It would be interesting to see the reaction if Hornby did the same thing, supplying locomotives in Small, Medium, or Large size. It's strange that a completely different mindset is applied to track. But Peco have prospered mightily from it. Martin. 3 1 1 1 Link to post Share on other sites More sharing options...

My issue with the ultra-finescale brigade is they obsess over things that can only be examined in the static sense, but things on a model railway are supposed to move. And that's when the problems start because models do not - and cannot - have the mass and inertia truly represented. Small example, a three link coupling swinging on a hook does not - because of basic physics - move like the real thing. (That has nothing to do with mass btw, that one is due to the period of swing being proportional to the length and we don't scale down time either.) 9 Link to post Share on other sites More sharing options...

It just needs to be long enough to avoid any short-circuits from wheels on adjacent rails. Wayne has got it just right. Let's not distract him with another quibble. Proper P4 modellers will solder the connecting rails direct to the casting, and make the isolation breaks in the prototypical fishplate locations. That way the connecting rails can be as short or long or curved as needed. e.g. for making regular or curviform (or other) V-crossings. Lesser P4 modellers will no doubt make them up exactly as supplied. cheers, Martin. 5 1 1 Link to post Share on other sites More sharing options...
Wayne Kinney Posted April 7, 2021 Share Posted April 7, 2021 Hi Guys, Regarding timescales on releasing the kits. Since the EM Gauge Society are supplying me the code 75 bullhead rail, I am first prioritising fulfilling their order for EM B7 kits. EMGS members will be able to order direct from the EMGS store at a discounted price. This is going to be my first time processing a batch order, and I am still finding my feet in mass production, but it's looking good so far This will push the Standard 00 Gauge release to the end of this month. Thanks for your patience and support, everybody! 10 1 2 6 Link to post Share on other sites More sharing options...

Hi, I am currently processing the EMGS order. All bases are now printed, 40% of switch blades are milled. Need to finish and despatch their order before the end of this week. Production so far has gone very smoothly, but I have been a little delayed by other work and family commitments. I am then away (caravanning) over the Bank Holiday weekend with my wife and little boy. On my return, I will be concentrating on releasing the EM gauge kits on my website, followed by the 00 gauge version.

RBAGE Posted May 6, 2021 Share Posted May 6, 2021 Will you be limiting orders for 00 gauge turnouts from the initial production run? I expect they will sell like hot cakes. Let me know when you expect the 00 gauge items to hit the market so that I can make sure I'm near a computer. 2 1 Link to post Share on other sites More sharing options...
