I'll make the cut after the track is glued in position to maintain the alignment.........that's the theory I'm adding droppers to every individual length of track so as not to rely on the rail joiners, I'll have droppers either side of the join connected via a plug of some description Edited May 7, 2019 by chuffinghell 1 Link to post Share on other sites More sharing options...
RMweb Gold Harlequin Posted May 7, 2019 RMweb Gold Share Posted May 7, 2019 You're quite right to take rail expansion into account. I can tell you from experience that it is a real phenomenon! The rails will move where they are least well fixed. So if you fixed them solidly to copperclad (or whatever) at the joint they would probably push inwards and maintain the gap at the joint rather than coming into contact. 1 Link to post Share on other sites More sharing options...
Martin S-C Posted May 7, 2019 Share Posted May 7, 2019 I have read that it is never wise to rely on a baseboard track break as an electrical break as well, for this very reason. 2 Link to post Share on other sites More sharing options...

I have thought about dispensing with the 'orrible joiners, leaving a gap but glue a piece of plasticard in the gap Edited May 7, 2019 by chuffinghell Link to post Share on other sites More sharing options...

I had a 2ft length of (code75) track do that in the sunny weather earlier this year: It is fixed to copperclad at a baseboard joint and butted up against the next length of track further inboard. It solved the expansion problem for itself by breaking the PVA bonding with the cork underlay and becoming bow shaped! People are right to not rely on simple gaps for isolation where the rails are not securely fixed, though. Edited May 7, 2019 by Harlequin 1 Link to post Share on other sites More sharing options...

That's quite a scary thought, especially happening over such a short length Fortunately the majority of the track terminates at a dead end, so maybe I should introduce an additional gap on the return loop to allow for any future expansion?..........it means extra droppers but I do need the extra soldering practice Link to post Share on other sites More sharing options...
RMweb Gold chuffinghell Posted May 7, 2019 Author RMweb Gold Share Posted May 7, 2019 (edited) It's also true that the baseboard material will expand and contract, this is why I used MDF as it expands and contracts in a different way to plywood, however Just like Gremlins don't get it wet The boards have been in place for nearly twelve months so I'm hoping the boards have acclimatised to the room.......this is a far better excuse for taking so long to lay the track especially when the truth is I've spend 12 months changing the track plans Edited May 7, 2019 by chuffinghell 1 Link to post Share on other sites More sharing options...

Martin S-C Posted May 7, 2019 Share Posted May 7, 2019 (edited) North Devon is nice too - Minehead, Watchet, Bishops Lydiard, Lynton, Barnstaple... Just, you know, nice scenery. I think we would all be wise to try and climate change-proof our layout construction as much as we can. I'm guessing palm trees will be at home in Staffordshire in 50 years time.

RMweb Gold Stubby47 Posted May 9, 2019 RMweb Gold Share Posted May 9, 2019 Or put a PW gang on site looking at it. For expansion joints, try cutting the rail at an angle, 45°+. Whilst maintaining the smooth flow of wheels, there is then much more lateral movement available for the rail. 3 Link to post Share on other sites More sharing options...

RMweb Gold chuffinghell Posted May 9, 2019 Author RMweb Gold Share Posted May 9, 2019 The other reasons for doing this is that are 1) I can use a full sleeper without having to modify it to accommodate the joiner 2) If in future I decide to remove said 'orrible joiner it will be much easier cut it out There is usually method in my madness 1 Link to post Share on other sites More sharing options...
RMweb Gold chuffinghell Posted May 12, 2019 Author RMweb Gold Share Posted May 12, 2019 (edited) First length now gluing in place (weighted down with 32mm steel bars) Droppers soldered to each individual piece so as not to rely on the fish plates Ive started with this particular run as it’s a straight length across the join, once dry I will use this fixed length as the datum/starting point for the rest of the track..... I’ve had to start somewhere Its taking me a while but my soldering is getting better Just taking it slow and steady Edited May 12, 2019 by chuffinghell 8 Link to post Share on other sites More sharing options...
