I polish the copper first with a fibre pen just to ensure it is clean.

Thanks guys, that's a big help.

Time to lift and bin some track I think.

Cheers

@Carl L.........instead of using flexi track which naturally wants to straighten up when curved could you not use a standard large radius curve across the joint which you would still solder to screw heads or copper clad sleepers......this track will stay curved when cut at the join and make the soldering easy.......HB

Or if you still want to use flexy, slide the sleepers off the rails and gently pre curve the rails a bit so they are not naturally straight.

Thatís a good point HB.

On my OO layout all the joints are deliberately at 90deg to the track but I do have four curved tracks crossing a lift out section on my N layout and yes, alignment was a challenge when I first made it using the brass screw method.

However when I made some changes to the layout I relaid the track using flexi and copperclad sleepers but refined the way I carried it out. I started by laying the track across the joint and connecting it up to the rest of the layout so it was set at the right length and position.

Then I removed the plastic sleepers where the copper-clad would go and slid the pcb into place and pinned everything in place with track pins. I did pin the plastic sleepers either side of the joint every three or four sleepers for an inch or two.
Now I tested that locos would run even though at this stage I hadnít soldered or cut the track.

Finally, I soldered all the rails to the pcb, cut insulating slits in the pcb surface and lastly I cut the rails with a slitting disc - and tested it all again. It may have helped that I used OO scale copperclad sleepers which gave a longer soldered area. For OO track on a curve I would use wider pcb sheet from an electrical supplier or two copperclad sleepers each side of the joint.

I found that doing it this way there was no movement in the cut rails at all.

Thatís what I did Steve. Made sure everything was flat, fixed, firm and working before cutting the track.

HB - Never thought about fixed curve track. That would certainly make things easier.

Steve - thanks for the detail of the method.

Before I saw HB's reply a visit to Maplins saw the acquisition of a big piece of copper pcb. Nice price as well. So we'll see how it goes.
