RMweb Premium Siberian Snooper Posted February 24, 2021 RMweb Premium Share Posted February 24, 2021 I like track building, once I'd mastered the dark art and having a load of kits to build I decided on EM as it's closer to scale, but has room to fit cross heads and crank pins. If I was a diesel or electric modeller I would have probably opted for P/S4. 2 1 Link to post Share on other sites More sharing options...
Jub45565 Posted February 24, 2021 Share Posted February 24, 2021 The clearance thing is a bit of an odd one - as across the face of the wheels EM and P4 are near enough the same (EM is a slightly narrower gauge, but with a slightly fatter wheel). It comes down to what we want to do, and what we enjoy doing - this is a hobby so we shouldn't really do things due to other people's opinions on how to spend our spare time. I wouldn't personally choose to ruin a walk by playing golf, but will happily meet friends who play golf for a pint afterwards... *misty eyes* I went P4, as when making the decision I was looking at a 108, Ivatt 2 tank and 3F as a base set of models. The 108 was Branchlines drop in sets for either option. Bachmann hadn't released their 3F, so it was a London Road models kit again equally applicable to either, and the Bachmann split chassis for the Ivatt I would choose to replace either way too. I don't mind spending some extra time fettling, and do enjoy that extra bit of detailing - so the choice, for me, was easy. 5 Link to post Share on other sites More sharing options...
RMweb Premium Mark Forrest Posted February 24, 2021 RMweb Premium Share Posted February 24, 2021 I think there is sometimes a misconception that people model in P4 just for the look of the track. For me one of the reasons I changed from EM to P4 was that I was looking for more of a challenge. I started out in EM because it only seemed marginally more difficult than 00, as I had always intended to build my own track. The switch to P4 was as much about the technical challenge of getting it to work as anything else. 3 2 1 Link to post Share on other sites More sharing options...

PenrithBeacon Posted February 27, 2021 Share Posted February 27, 2021 For me it was the missing 2.33mm in track gauge compared with 00. I wouldn't tolerate a boiler being short by that much so I really didn't and don't see why the track should be narrower. Compensation, where needed, is simple for C&W but a challenge for locomotives. But I'm getting there, I've actually managed to work out how to assemble wobble free AGW wheels, a major step forward. 2 Link to post Share on other sites More sharing options...

Anything works - if it's built properly. I've seen some diabolical OO layouts in my time. And some EM ones too................. 1 Link to post Share on other sites More sharing options...

Then I placed the wheels in position Then I assembled the jig in the vice and used a 3" G-Clamp to squeeze it all together using a back-to-back gauge to get the all important back-to-back correct. That's it! It takes less time than it does to write this. Edited February 28, 2021 by PenrithBeacon 2 1 5 1 Link to post Share on other sites More sharing options...
5050 Posted March 1, 2021 Share Posted March 1, 2021 (edited) I've faced mine with 20thou plasticard either side of the sprung 'stubs' - but never thought of taping the wheels in position. Doh! One of my bugbears is the wheel falling off the stub when putting the halves together. Tthis idea should cure it. Thanks David.

PenrithBeacon Posted March 1, 2021 Share Posted March 1, 2021 Your very welcome! I think that cocktail sticks and masking tape are my most used tools. This idea of using plasticard with the GW Quartering Jig seems to have been a very well kept secret. I would have benefited from it if I'd have known! It would have saved a lot of effort developing my ideas illustrated above and a lot of frustration with wobbly wheels. Link to post Share on other sites More sharing options...

Gravy Train Posted March 28, 2021 Share Posted March 28, 2021 I find that EM is the perfect compromise, in all it is only the width of the top of bullhead rail when you look at it. If your exhibiting, EM is much more forgiving, P4/S4 are much finer tolerances and less forgiving and everything has to be absolutely bang on. If you have exhibited a layout in EM and an onlooker asks ‘ is it EM or P4, you start to ask yourself questions and the first one that comes to light is, ‘How come they didn’t know’ Peter A L 2 1 Link to post Share on other sites More sharing options...
davegreenly Posted April 2, 2021 Share Posted April 2, 2021 Some years age, a punter in front of our layout, Manafon Mills, asked his pal, "Is this EM or P4?". His pal replied, "I think it's EM, they seem to be enjoying themselves!" 3 3 Link to post Share on other sites More sharing options...

EM and OO have identical standards and I take your point that if you want fine track then fine scale P4 is the only way but life is full of compromises. Griff I don't think so, unless you look at one of the 00 gauge derivatives (00SF) But as said its easier to work with than P/S4 Link to post Share on other sites More sharing options...

Edit: Now I feel like a total numpty as it’s 4mm to the foot, so of course 1mm equals 3”........... Just never heard it expressed in those terms.......and I’ve only been modelling in 00 for something like 60 years.....

Jeff Smith Posted April 3, 2021 Share Posted April 3, 2021 I like an eye level layout. The track gauge is not so obvious but the wheel flanges are, especially on steam locomotives. It seems such a shame to spoil the appearance of a lovely RTR or kit built loco with large ugly flanges.......TLCs as well, but that's another story! P4 wheel and track standards completely eliminate the wheel drop in points. Regarding getting Gibson wheels on square I use a small press that came with various bits including one with a 1/8" blind hole that securely holds the axle for pressing into the first wheel. Then I use a plain bit to push on the second wheel. 1 Link to post Share on other sites More sharing options...

It's not about levels of tolerance to faults, they genuinely cant see each others viewpoint. I tend to see proportional differences instantly, its not a case of comparing against photos to find faults. I dont think it's just (over) familiarity as, for example, I find it pretty easy to tell two similar racehorses apart from their faces, even if I've only seen them once before. Conversely I really struggle with even simple forms - my visual recognition or whatever part of the brain it is, genuinely just sees a splat of apparently random words and boxes and takes a real effort to "see" what's there whereas others could fill it in barely even glancing at it. I have no idea if this is a real thing or not but it would explain how we get such polarised opinions because it would be less about what you chose to accept and more what you actually "see" (or recognise) in the first place.

I can agree with you on this one, in my golf playing days the best part of my game was the short game (chipping and putting). On 16 of the greens I was deadly, but the topography on two absolutely baffled me. Some golfers would hold their putters up like a pendulum to read the green, try as I may I could never see what they did. In train spotting days I had a friend who would instantly know whether its was a black 5, jubilee or rebuilt Scott from distance, to me they were all dirty black 4-6-0's I think with modelling some see perspective totally different to others. With trackwork many don't look downwards, resulting with a lack of knowing what it should look like 1 Link to post Share on other sites More sharing options...

I did the same thing deliberately with my late EM layout. I used the old Ratio sleeper bases and used EM for the straights & the 18.83 version for the curves. No problem as when curved (both gauges) tended to narrow anyway. Effectively gauge widening - easy. Although I'll admit, I did buy the 18.83 in error. 2 Link to post Share on other sites More sharing options...
