Put a cork in it

October 11th, 2009 David Rickard No comments

Having laid all my track down, and run trains a few times, I found they were a tad noisy. Not only that but the surface wasn’t looking too great. Some of the track was a bit higgledy-piggledy, so I decided I’d attack it in two ways. Firstly, I’d rip it all up, and secondly whilst I was doing that, I’d lay down cork tiles.

I’d looked previously to try and find tiles, but drawn a blank. I was in Wickes a few weeks back and happened to stumble down an aisle where at the end was a pile of cork tiles – they were in a totally random place, next to shelving as I recall. I went back again this weekend to buy some and found they’d moved again onto some other random shelf, albeit closer to flooring than the last lot. I purchased a couple of packs – each covers 0.84m2 and I had just over that, so I knew I’d need a couple. They’re not bad at £7 a pack.

Books to hold down the tiles

Today I pulled up all the track, and started gluing them down. Thing is, I’d gone through all the pain and heartache of putting in my point motors – the arms on some of them will still reach (they were too long) but a couple will be too short. I think I’m going to have to make some sort of extension for them, which could prove fun. I have a feeling in re-laying the track nothing will line up anymore. That’s sort of a mixed blessing, as some of the alignments on the motors was pretty rubbish anyway.

I glued down the tiles with plain old PVA. They were pre-varnished, so I glued them varnish side down. They’re sticking fairly well that way. I was worried if they were varnish side up I’d have a lot of trouble getting scenic elements to stick down properly. I’ve applied a bit of weight using various nice big books. I might not have finished my CCNA, but the study guides have come in handy!

When I start putting the track down I’ve got a few baseboard joins to do, which I’ll do the old-school way with copper-coated PCB. Should work well. Once I’m happy with the track, I’ll finally stop procrastinating and wire up the point motors!

The Green Green Grass

September 19th, 2009 David Rickard No comments

I decided I wanted to have a whack at ballasting, and whilst I was at it, I may as well try out other scenic techniques. In the past I’d made some very bad ‘grass’ areas using the basic scatter material, so this time I thought I’d see if I could do better.

I had a Noch starter kit, which included scatter, static grass, a grass mat, lichen, trees, and other random stuff.

So I took a spare bit of Plywood, and started work.

First of all, I glued down a piece of spare track, and painted it with my airbrush. I used some acrylic Burnt Umber, which was lightened down a touch to make it look more rusty.

Next, I used the age old method of PVA and Water in a 50:50 mix, with some isopropyl alcohol to make it flow.

Next up I laid some static grass. On one side I painted the base first a brown shade. The other side I didn’t bother. I basically wanted to see if it made much difference. It seems it did to a certain degree, but I think the shade of brown I used was a bit too brown, and not sufficiently earth-coloured. The reasoning behind doing it was that it gave a nice base, and didn’t show through as much as just plain baseboard.

I also stuck down a section of Scalescenes road, and edged it up roughly with static grass. Plus I stuck a couple of trees in.

On the whole it looks OK, and makes a good starting point. As it stands, it’s a bit sterile, and needs detail. The details should make it look better.

Not bad for a first attempt though!

Round and round we go

September 18th, 2009 David Rickard No comments

I visited the International N Gauge show last week. There were some nice layouts there, and one major thing struck me – they nearly all formed a continuous loop. I think this makes for more operational interest, and allows for more interesting trains. Freight trains can rumble straight through the station, as can non-stopping express passenger trains. I’d otherwise not really be able to do those in the space I have. So now the track plan looks like this:

Trackplan

Which I’ve done by using a small extension on one end thus:

P1000551Admittedly, since I’ve done it, I’ve re-laid that section of track, as it wasn’t great. It’s now done in two continuous pieces rather than the four I first did it in.

P1000550So now I have a nice continuous loop, and the trains run around it full tilt quite happily.

I think I could do with a couple more power droppers elsewhere, just to give a good supply, but even then there’s no dropouts, and I ran the Dapol 67 round on a fairly low speed with no problems.

The extension won’t be scenic – it’s designed to be removed when not in use, so I’ll hide the edge with a bridge or something. But it’s all good progress.

Annoyed Grunt

July 19th, 2009 Dave No comments

I’ve been having an issue with the double slip on my layout. I’d wired up the Seep switching motors, and followed the leaflet that came with the point, but I had this strange issue with a short. Every time the loco I had got over the points, it’d short out. I’d hear it spark, and the controller would show an overload protection kick in.

I re-wired bits countless times, and followed along with my multimeter but couldn’t fathom it. Then I suddenly noticed what was up:

19072009070

Can’t see it? No, neither could I. Took me a whole week to suss it. Basically, the curved point at the bottom is not set to turn out; i.e. the top blade is touching the top rail, making both the rails leading into it the same polarity! Because there’s insulating joiners between it and the double slip it’s all fine until the loco runs over onto the curved point. As soon as two pickup wheels are on it, there’s a short.

So once I spotted this, I flicked the point over and ‘lo and behold, it magically works! Well, the loco will run until the wheels are all on the curved point, at which point it stops dead, as there’s no power that end yet. I’ve been slowly working along, ‘debugging’ and fixing before moving onto the next bit.

I just need to add more power feeds, then wire up the point motors. Then wire in the CDU. And make the point control panel. But then it’ll be operational, and it’s on to gumming up things with glue and ballast.

Wired for power

July 11th, 2009 Dave No comments

I’ve been doing a little bit of wiring today. Nothing amazing, just getting some power into the rails. I’ve been around with insulating joiners, and I think I’ve got them all into the right places now. I’ve also been following up with my continuity tester, basically checking places where I think there should or shouldn’t be continuity. I found a couple of places where the opposite rail was carrying the same charge due to the electrofrog on the previous point being switched. I think I’ve got them all now though.

After working it out, I realised I needed 20 power connections! I’ve found the easiest way to accomplish this is to bare the end of a wire, and bend it to 90 degrees. Once tinned, it can be attached directly to the underside of the end of a rail, OR a metal joiner. A carefully drilled hole below it takes the wire away. The theory being that once ballasted, it’ll be unnoticeable. I did attempt to fix one to the side of the rail (a technique I know is perfectly valid) but in N gauge it’s just not do-able. In OO perhaps, but N is far too fiddly.

So far, I’ve got power into a siding. Woo! My carefully drilled hole wasn’t so careful though, and as a result the track doesn’t fit properly. I’m not worried though, as I’ll just re-drill the holes.

I’ve managed to knock quite a few random holes into the board, and I’ve decided I’ll get around those just using some sort of filler. There’s a couple of bigger holes which a piece of card would be able to bridge. I’m intending on adding a little bit of undulation to the whole base, so I’ll probably do that with a mix of filler and other fun things.

But there’s still another 18 power connections to do yet…

All change!

July 6th, 2009 Dave No comments

So, the weather has changed, and naturally, so have my plans.

I got rather fed up with the scissor crossings. The wiring was ‘fun’, but no impossible, but that wasn’t the deal breaker. The real issue was that I couldn’t get the point motors to align in a sane way. They either clashed with eachother, or with the board framework. So, I decided enough was enough, and they have now been replaced with ordinary points. The motors for those fit in fine, and the wiring issue is gone; now I just need insulating joiners to work with the electrofrogs.

The joiners ended up costing me a lot more than I planned. It seems Dapol have had a class 67 model coming for a while, and whilst looking around on the web for the joiners, I found the pre-orders for these fine new models. So I’ve got a 67 in EWS livery, and, the one I really wanted, a 67 with MK3 coaches and DVT in Wrexham and Shropshire livery! So that’s pleased me no end. Hopefully it’ll fit in the platform.

Progress overall has slowed a little, but now my issue with the scissors is gone, I can plod on far more easily. I need to solder power connectors onto some more point motors, and re-lay some of the track, but I’m not a million miles from wiring up the power. Next it’ll be onto ballast, and we’ll actually be getting somewhere.

Soldering on

June 19th, 2009 Dave No comments

Now there’s a slightly more definite track plan, I’ve started work on point motors. I read up on some stuff, including this nice article on the N Gauge Society website. I pondered things a bit, and here’s the decision I came to.

Point motors

Going with Seep, as they can mostly hide under the baseboard, they’re very low profile, and they’re simple. Peco’s motors require hacking great big holes in the board, whilst the Seep motors need a tiny hole for the armature.

Wiring

Colour coded, naturally. I found some stuff in Maplin which looks like it’ll do the job.

Power

I’ve got an old controller in the loft (I think it’s a Gaugemaster, or something) which has an accessory supply, so I’ll bring that down and use that for now. Or at least, until I look into DCC. I’ve also got a Gaugemaster Capacitor Discharge Unit (CDU) which will help fire the motors. For the scissor crossings I’m planning on making up a couple of push-button diode matrices, with relays switching the electrofrogs, but I’ll do that after I’ve got the basic points working.

Connections

P6190047 I pondered this for a while. The above article mentioned using terminal blocks, which is a nice idea, but I’m not a great fan of them. I pondered some more, then realised I already knew of a perfectly great connector. The Molex Hard Disk connector! They can take the amperage, and the wattage I need, so they’re quite suitable. Plus, pretty easy to fit (crimp on pins), and it all just pushes together. If I want to remove something, I just pull the connector out. For bigger connections I can use the motherboard connectors, or multiples of these.

I’ve made up eight point motors so far with the female Molex connector on (technically, it’s back to front to how it goes in a PC, but I’m not fussy), and they look pretty good.

P6190045

The screws I bought to fix them on are just the right length – they’re a bit long actually, but with the thickness of the point motor’s PCB, it should almost fit without sticking out the stop. So what if it does though, it’ll all be hidden under scenery!

I might have a bash at screwing one of them in and testing it out. Once I’m happy with all the point motors I’ll move onto the other electrics.

I’ve been working on the railroad, all the live long day

June 7th, 2009 Dave No comments

I’ve been laying some track this afternoon. I spent a while fiddling with the curves, and laying things out.

I started at the back, and slowly worked around to the front on the longer sections. Laying the curves wasn’t too bad, but they’ve taken on more of a ‘D’ shape than the original plan.

P1000539

Not really a big issue, as it means a more sweeping curve, and not only that, it lines things up a bit more nicely for the scissor points.

Notice the slight bodge on the end of the curve though:

P1000540

I should have started with two lengths from either end, and trimmed them down. Then I would have had a nice join the middle. But no mind. I’ve run some wagons over them, and they go over fine. Due to the fact I’ve pulled the baseboard out and sat it on the bed, it’s a little inclined. I was having great fun sending a little wagon round the full length just by pushing it hard at one end, and letting it make its own way round under its own momentum. I figured if it was binding anywhere, or likely to derail, it’d definitely do it then, and it went round fine each time, even crossing the points when I set them to crazy things, so I’m reasonably happy it’s OK.

There’s a light pencil line which marks a 275mm diameter curve; my curves are a bit more than that, so I’m well within tolerances I think.

Unfortunately I need to wire up the electrofrogs before I can actually get anything running around. I think I also need to look into point motors and their fitment before I go crazy sticking down track. The curve is nailed down, but only because I have no plans in ballasting or doing anything with it (you can’t see it anyway). Long term that might change if it moved to a location where you can see it. The fiddle yard at the back has also been nailed down.

I’m quite pleased with the high difference between the code 80 and code 55 track. I don’t envision it causing a problem as is, but if required I’ll file it to fit. So far, so good though. I might lay a bit more track today. At least my little Woolies Dremel-alike drill is coming in useful for cutting the track.

I printed a building!

June 6th, 2009 Dave No comments

I had a go at making one of the buildings from Scalescenes today. I got myself some card, PVA glue, a Pritt stick, and a new knife and cutting board and set about making it. The result isn’t too bad.

P1000538 

Yeah OK, it’s not great. It took me about four hours to put it together, but I was speeding up a lot once I got a feel for how the kit worked, and I was stopping now and then to do other things. One thing I learned was I need to pick up some sort of proper glue spreader/spatula. I was just squeezing out a blob of glue on my finger and smearing it about a bit. Ahh the wonders of PVA!

I intend trying to make some of the bridges in future though. I’ll do a MUCH better job on those.

A plan forms… sort of

May 30th, 2009 Dave No comments

I’ve been playing with XTrkCad and trying to work out how to make things fit. For a while, I was convinced I’d be forced to use Code 80 track to get the turns I needed, and fit in the maximum amount possible. Eventually I managed to find a nice workaround – I’ve extended the base board!

plan

An explanation is required. The blue section at the top will be the back of the layout. That will be mostly Code 80 track (stuff I already have). The scissor crossing is a nicety for two reasons. Firstly, it’ll be the conversion from Code 80 to Code 55, and it’ll give some flexibility in switching on the up and down lines. It’ll serve as a fiddle yard, and stock storage.

The red section on the right is the new extension. It’s a 300mm section which will be bolted onto the end. It’ll also hide under an adjacent shelf, so it won’t really be visible. Hopefully there won’t be too many derailments there. The track will be Code 55. There’s not a lot of difference in price on the flexitrack, so it was easier to extend it up.

Lastly, the main section down the front is the actual ‘live’ layout. The two straight lines down the bottom of the plan are down to the ‘station’. It’ll be a simple terminus. The scissor crossing allows switching across onto the up and down lines, and also up to the sidings. The left hand side should be a depot of some description, and the double slip allows one of the sidings to act as a sort of head shunt for the two shorter sidings. They might end up being some sort of loading bay, or something. Not really sure yet! They might be pulled around a bit more so the run more diagonally. That would give longer running lengths, but it’ll mean more of a twist – I already have a pretty tight radius in there.

The leftover space will have the usual assortment of buildings and other miscellanea. The exit point for the track will be a bridge of some description, and probably a raised roadway along the whole right hand side.

As far as realism goes, I’ve tried to keep to the spirit of things. I’ve had a look at some satellite photos of depots and stations, and I’m trying to do things as well as I can in the space confines I have. To do things properly I’d probably end up with a layout about ten times longer. What I wanted to avoid was a full loop system – I wanted something vaguely plausible. Hopefully when dressed up nicely, any oddities in the track layout will be solved.

The track has been ordered, so I’m committed now. Or should be.

Incidentally, I’ve gone for entirely electrofrog points. Probably going to end up being a really stupid idea, and require a ton of wiring and switching. But hey, that’s what makes it fun!
