Thank you for your replies! I realise that I had mistakely posted the same picture twice rather than posting the other picture that I had intended to post, an error which I have now remedied.

As to copper clad - I have planned the whole scenic section with SCARM using geometary from the British Finescale range, which, splendidly, is actually included with SCARM. However, the flat bottom turnouts are not yet available from British Finescale, so I am contemplating whether to have a go at producing these with 2mm FS kits/parts, which I believe that I may have read somewhere can be made up as N gauge using replacement jigs/gauges (not the Easitrac type, but perhaps the "Versaline" chair type); but I am not sure whether this will be beyond my ability.

Thatís significantly more complex than just building direct onto PCB sleepers, without any of the versatility, I really wouldnít do that.

But without the chairplates, surely one just has blobs of solder between track and sleepers on the turnouts, which do not look like reality at all?

It worked for Peter Denny's Buckingham Branch Lines  :thumbsup:

Quite a few layouts use this approach. The 2mm Scale Association book on track is worth reading, itís got lots on the different methods of construction.

If you get uniform Ďblobsí of solder (like by using solder balls) then it does look like a chair plate, which are so tiny in N anyway Iíd not be too concerned.

Personally for me the cast frog of the Finetrax grates visually far more. Wayne blackens his though, which looks immeasurably better. Certainly makes construction easier too.

I do have the 2mmfs book, which is very good - I can't imagine being satisfied with blobs of solder. I can see the individual chairs on the fiNetrax points very clearly.

I was planning on blackening my cast crossing, too, which otherwise would look very silly.

I have no experience with this trackage system, but to me the cast frog/crossing seems to let it down when trying to achieve something closer to 2fs.

I believe Burton on Trent uses plain PCB pointwork, and that looks stunning to me.

I have slightly modified the plan for the fiddle yard so as no longer to require the SL-U396 that I was missing and to take advantage of one of the extra SL-U395s that I have:



The modifications are visible on the right hand side. This does actually increase the lengths of one of the fiddle yard roads by a few cm, which is a good thing.

As to the trackage, the cast crossing looks silly in its raw state, but should look fine once it has been chemically blackened and the running tops cleaned. I really think that I would notice blobs of solder instead of actual chairplates: the layout is designed to be eye level for sitting down, so the track will be looked at quite closely.

Have you looked at Burton on Trent? You may be surprised what it actually looks like, rather than what you assume it does.

Bear in mind you donít really have chairs on FB track anyway, and how small is a scale Pandrol clip, about 0.3mm maybe? Do what you think is right of course, but I think youíll be surprised.

I have seen pictures of this method of track laying in the 2mmFS book, but I do not believe that I have seen this particular layout; do you  know where I might find any pictures, especially high resolution/close up pictures of or featuring the turnouts?

Short thread with pictures here, with a much longer one on RMWeb here.

Cav's using 9.42mm FS standards on plain track, tapering to 9mm for the pointwork, but I believe it's all just plain copperclad. Chaired is great for BH, but IMO not for flat bottom.

Thank you - I will have a look at those.

It is interesting that you mention a difference between chaired track for bullhead and flat bottom - can you elaborate on the significance of this?

There are exceptions, of course, but flatbottom track doesn't use chairs, it uses Pandrol clips (or similar), which are far lower profile than a chair, original ones were a bit bulkier, but on the newest track they're even more low profile:



Bullhead in the background, with the bulky chairs, and flatbottom in the foreground, with much lower profile clips holding the base of the rail onto the sleepers. Those are actually the older style Pandrol clips too, current ones are smaller.

I understand the difference between actual fixings for flatbottom and bullhead track; but what I meant to ask - my apologies if this lacked clarity - was as to the significance of this difference in real practice to how suitable that model chairplates are for turnouts in 1:148 scale.
