Track Laying Begins Part 2.....

Make that a half out of three which is a bit of a shocker. We did not complete laying the track for the top yard as we had thought would be certain.

I have built layouts before and worked on many club layouts but that was many years ago. That was in HO while this layout is O Scale. Clearances had to be right as we did not want to have the same problems we had with the garage layout where we had to pull up and relay sections because of the lack of clearances near pointwork.

I had purchased a pack of cork tiles at Bunnings with the intention of cutting these up to use as ballast underlay but we decided not to go with that. I now cut the tiles to act as spacers so as to get the track centres right and to ensure tracks were straight. We found it was very difficult to see a centre line drawn in pencil on the baseboard as with the 54 inch height of the baseboard we could not easily get above the track to ensure the track was centred on these lines. Using the cork as a spacer made the task somewhat easier.

Work continued on this first section through the station yard on Monday night making sure the track was straight as it was spiked down.

Raymond took the day off on Tuesday with the intention of getting us much track laid as possible, the installation of point motors and wiring to allow something to run.

I arrived home at 4:00 pm on Tuesday ready to help Raymond clean up and get ready for Mackie’s Marauders who would be arriving at about 7:15 pm. I found Raymond sitting on the back steps looking rather dejected. He said he had struck some problems and had not progressed as far as he would have liked.

Raymond listed a litany of problems which he had found so frustrating. Installing the Cobalt point motors was OK where he could get at them from under the layout but the three points in a row at the left-hand end of the station loops were directly over a 4 X 1 timber L-Girder which was lying with the 4 inch side laying directly under where the point motors were to go. This did not allow him to get the Phillips Head screwdriver in to fix the motor in place although there was plenty of clearance for the point motor. The heads of the screwdrivers we had were also badly worn and did not easily work with the small headed screws. The Template we had used had located the actuator arm OK but the pilot holes to mount the Cobalt motors did not match. This was not found to be a major problem as the screws were self-tapping and could be screwed into the baseboard relatively easily where he could get at the screw locations. The wiring had also been an issue as there were no drill bits available to give a large enough hole for freedom of movement.

I tried to cheer him up saying one of the Marauders would be able to supply a solution.

We vacuumed the shed and got the supper ready and the tea urn on for hot water.

The guys started rolling in at 7:15 pm and all were pleased that we had made at least some progress. We had a good turnout with eleven present (including ourselves). It was especially pleasing to welcome PeterH from the Sunshine Coast. Peter used to live in the same suburb as but he and his wife opted for a “sea change” some years ago.

As I had predicted at least two of the Marauders came up with a solution (the same in fact) for the fixing of the point motors above the 4 X 1 L-girder.

We had our usual gab fest with the Marauders exchanging ideas and talking about their latest progress about various projects. MikeB is one a senior member of the group and one of the most prolific scratch-builders. He seems to have a keen eye to turn a piece of junk or bits and pieces into an eye-catching model. Raymond and I would like to thank MikeB as he presented us with one of his scratch built models to decorate the scenery on our new layout.

We spent a pleasant evening looking at the latest journals with our copies of Narrow Gauge & Shortline Gazette, 7 mm Scale Journal; On30 Annual 2011 and Narrow Gauge and Industrial Railway Modelling Review available for the guys to look at. We are hoping to turn them to the “Dark Side” modelling On30 narrow gauge instead of that HO Scale New South Wales “stuff”.

Later in the week I purchased a 25 mm and 18 mm spade bits and a couple of Phillips Head screwdrivers on my way home from work.

Track Laying Begins.....

I am sorry it has taken so long to update my Blog but little physical work has been done on the layout so there has been nothing much to report. Raymond and I have had many discussions about how we should do this and that – mainly wiring. We have done some modelling, however. I have done some more painting on my Walthers Cornerstone building and Raymond is building a Slaters 16 mm Scale Slate Wagon kit.

We have not made any progress since my last post with regard to track laying until this weekend of the 19 – 20 February when we suddenly realised there was some urgency involved.

I had ordered a range of Perspex track aligners from Brunel Hobbies which arrived on the 11 January. I wanted these so we could ensure we had smooth curves to the required radius unlike the major issues we had with the layout in the garage. Our desired radius on the main line is to be 36 inches but we can go down to 30 inches. Our fleet of MMI locos require a 26 inch radius minimum.

One thing that I have found very frustrating is the lack of conformity in the descriptions between the various ranges of Peco Turnouts. We are using Peco On30 Code 100 Flex Track. When we were building the garage layout we purchased two of Peco’s Medium Radius On30 Turnouts thinking they would be 36 inch radius only to find to our dismay they were actually 24 inch radius and the MMI locos did not like them. We had no choice but to purchase the equivalent range of “standard gauge” Peco Streamline Turnouts as there were no other radii available in Peco On30 pointwork. We bought the Large Radius Turnouts on the assumption they were 36 inch radius which was what we wanted. This assumption was false. Peco Large Radius Turnouts are 60 inch radius as we discovered in planning the trackwork for The Shed layout. The following Table will give you an idea –
Peco Streamline Turnouts
On30 “Standard Gauge”
Small Radius (Left or Right) n.a. 24 inch radius
Medium Radius (Left or Right) 24 inches 36 inches
Large Radius (Left or Right) n.a. 60 inches
Curved Turnout n.a. 60 inches/30 inches
Small Radius Y Turnout n.a. 24 inches
Y Turnout 36 inches n.a.
Large Radius Y Turnout n.a. 72 inches

We have also had much discussion and soul searching as to the wiring needed for each of the layout requirements. We had searched various web pages and asked a number of our friends. DCC Concepts recommended heavy duty wire for the main power Bus and less thick wire for the droppers and less again for accessories. To “muddy the waters” so to speak some descriptions of wiring thickness was in American Wire Gauge (AWG) while most Australian specifications only state the thickness in cross-sectional area.

We finally purchased our wiring requirements from Jaycar during the week ending 18 February –
2 X 100 metre rolls one each of red and black 12 AWG for the main Power Bus
2 X 100 metre rolls one each of red and black 18 AWG for the Dropper wires from the rail to the Power Bus
8 X 25 metre rolls one each of red/black/white/yellow/orange/green/blue/brown 25 AWG for accessories (point motors etc)
Total cost – $430.

Thanks to SteveM and CraigM for their valuable advice and critique.

Saturday, 19 February Raymond purchased five Left Hand and six Right Hand Peco Medium Radius Electrofrog Turnouts. These are Peco’s newer design which is supposedly set-up to make it easier for DCC requirements. They would also replace all the Large Radius Turnouts which we had so far salvaged from the garage layout and they would take up less space allowing for longer siding lengths.

Raymond spent Saturday afternoon (19 February) setting up the first Peco Turnout with dropper wires and a wire to connect to a Cobalt point motor. He had an increasingly frustrating time to solder the wires to their respective locations on the curved turnout he had tackled. He also soldered dropper wires onto the first three lengths of Peco On30 Flex track. After a few selected adjectives and much grunting and many sighs he eventually got the job done.

I spent Saturday arvo setting up a temporary section of baseboard so that we could get the curve right from this first turnout around to parallel the back wall of the shed. Nothing would be worse than to find our proposed 36 inch radius mainline curve would either run into the wall or go too close to it when it came time to build the section of baseboard and track section, along the back wall of the shed.

Sunday 20 February we started to get serious. We spent a lot of time setting out the location of the first point which was near the back wall of the shed. We had a number of “givens” which could not be changed to meet the track plan we had in mind.
• The radius of the main line entering the first turnout from the back wall of the shed was to be 36 inches
• The first turnout was to be a Left Hand Curved Point (Radius 60 inches/30 inches) which Raymond had managed to pre-wire on Saturday.
• The radius of the track from this first turnout around to parallel the left-hand wall of the shed was to be 38 inches on the outer diverging track and 30 inches on the inner track. It was felt that this would maximise the clearance between the two tracks as soon as possible after the divergence.
• The track along the left-hand wall of the shed was to be 12 inches from the wall. This would allow a station (Depot) to be located between the wall and this track which was to be the main line. The preferred choice for this depot building is Ouray from the Raggs to Riches range of laser-cut kits.

We located the first turnout using the above criteria. We had purchased the DCC Concepts template to allow us to drill the pilot holes for the fixing of the Cobalt point motor under the turnout along with the hole through the baseboard to connect the motor with the tie rod on the turnout. We found the task of using the template very difficult initially. The template would move on the turnout whilst drilling the pilot holes and the 0.8 mm drill was so fine we were worried about breakages. The tiny twist drill was too delicate to use in a standard Bosch 18 v battery drill which was too heavy to keep vertical and the use of a pin vice was too slow doing it manually.

I went off to Jaycar at Underwood and purchased a moto-tool that came complete with a flexible drive shaft (we already have a Dremel but no flexible shaft) and a 10 pack of spare twist drills – all for the princely sum of $58.

With this set up and by using a length of sticky tape to hold the template in position we soon had the pilot holes for the first turnout drilled. We then spent Sunday afternoon laying the first passing loop track.
The first lengths of track have been laid. The track nearest the wall is the main line and the station road. Ouray Depot fits between this track and the wall. 20/02/2011

Sunday evening, Raymond, modified and wired a further three turnouts and another couple of sections of track which we then laid in position.

The reason for this hive of activity? The Tuesday Nighters, alias Mackie’s Marauders, are to come over for an inspection this Tuesday night 22 February. They had decided to come to our place at their fortnightly meeting held on the 25 January. They said they were giving us a month to lay track, wire it up and get trains running. Well, one out of three isn’t bad.
