laying curves with flextrack

I finally came up with a simple solution. Just wrap the track in small lengths of masking tape at right angles to the length, roughly one piece of tape every 3". This holds the track firmly and stops it pulling free of the chairs
Once the track is laid and pinned, cut the tape at one side and tease it out from under the rail. Finally got my curves down and coupled up.
If anybody has already sent this, my apologies. I am just so happy to have solved my problem I had to share it:doublethumb

It was in an awkward position and n gauge track seems very easy to unseat, it's not the first time it's happened, just the most expensive, or I can spend many happy hours threading rail back through the chairs (as if I haven't got enough to do)
Top Tip- Masking tape shares will be on the rise until I finish tracklaying

Lucky I never had the grandchildren this week, the air was blue this morning!:oops:

Tracksettas by Peco. They have slots in them, so you can
pin through them as you work.

On my 00 flex - I usually lay both pieces together in a straight line & solder the fishplates, then curve the now 2 yard length of flex.
Then you might have problems with expansion.
The fishplates (rail joiners) do allow the rail to slide in and out a bit.
Even in 'sunny' Stevenage the difference in the gaps can change just
by having the sun shining on the track, so unless you have accurate
climate control in your layout room, you must leave small gaps between
the ends of the rails (within the rail joiner) for expansion.
When I curve a length of flexi, I allow the inner rail to protrude and
then make the joint staggered (by up to 5 sleepers). That way you
don't get the usual kink that happens at the joining point.

I also have a lot of track soldered to PCB sleepers which once ballasted with very fine stone & PVA , does not move.
When I lay track, I pin both sides of the sleepers around every 4" / 100mm to maintain the positioning because ballasting is not done until all wiring is completed & much operating by the crew to confirm the track plan is viable.
My D&S has been known to do many minor changes as operating problems arise.

I have the track seta things as well and the preformed slots never even occurred that they were maybe for the purpose of pinning down the track whilst maintaining the form.
Thick or what

That's what the slots are for Toto but there's always a down side ………………:roll::roll:………………………………..

If you pin through those slots, unless you push/hammer the pins right home, you can't slide the Tracksetta along the track because it jams on the raised pins.
I usually put the pins in just behind the Tracksetta as I slide it along the rail. That way, you can set the curve or whatever a full gauge ahead of your current fixing point. It gives you about 9 inches or so of "sighting" before the track is fixed down.
I tend to avoid Peco pins because they're so thin, you can't get them into anything resembling wood ……………:???::???::???: - but I do pre-drill the sleepers ready to take the thicker pins.

I pre-drill through sleepers & into the wood with a drill around #70 size which allows Peco Pins to be hammered lightly home to hold track without too much problems. Possibly one pin in 20 bends !

The Peco ones I've had are so thin I doubt they'd take a hammer ……… I think the idea is that you push them through the sleeper with either a pin pusher or pliers. They're quite long but probably superb for fixing track to the old "Peco" recommended structure of their track, their foam rubber underlay and Sundeala baseboard.
I've got 2 or 3 packets spare because I forgot Hattons sell that type. I'm blowed if I know who makes my favoured ones but they're shorter and thicker but still that blue/black colour. I can't even remember who I bought them from but NOT Hattons ……………….

Hobby Hammer with Interchangeable Tips work well - I have used them for years pre-drilling into MDF.

I do use a small tack hammer but maybe I should drill deeper ………:roll::roll:

Laying long curves can be tricky.
Tracksetta plates are handy but limit you to fixed radius curves.
I do use them where they suit a plan.
My other method is to use those long drawing pins with plastic handles.
Lay the track flat with one end a short distance before where you want the curve to start.
Push in pins up against the outside of the rail edges on either side between the sleepers, Say 4 pins opposite each other to hold the straight section.
Next start working a curve into the rail pinning again either side as you progress.
You will end up with a nice smooth curve which can be easily adjusted if neccessary if you want to vary the curve radius..
The pins also hold the curve ends for cutting to accept the next length of rail too which you continue with pins to extend the curve.
When happy you can pin the track down tacking the sleeper's.
Or running glue underneath the sleeper ends.
As the drawing pins are long you can gently lift the sleepers and work in some glue. I find a dab of evostick placed onto either a strip of flat plastic or shiney card ideal to use for working the glue under the sleeper ends.
Useing glue on sharp model radius curves in this fashion limits gauge rail closure which can happen if you pin the middle of sleeper,s.
regards,
Derek.
