That turnout sounds a bit long at 10" Nigel, isn't it going to take rather a lot of space up on the plank?

Hi Ed,

One of the things I am pondering. I would like 3 tracks running into the turntable, one out to the fiddle yard, so....

With a symmetrical three-way the length is  8.25"/21cm, if I used an asymmetrical #4 it would be about 14.5" /37cm. The issue with a symmetrical three-way is the requirement for double point blades, which means just the the rail web. With anything less than code 127 this is problematic. I did try it. The Peco symmetrical was in the spares box, their system of  blade pressings works for a three way. I think it's one of the reasons why there are no other commercial offerings of a three-way. So I bashed a narrow gauge one. It may go on the fiddle yard, used in another modue, or stay in the spares box. Next step is to use some track and see what it looks like. I have that #4 wye that could be used instead. And a cunning plan for the turntable that will shave a few inches.

One other way is a three-day stub, I may have a go at one of those as the double point blades would be eliminated. 

One of those cases where less may be better, and best determined before track meets glue. And avoid the consequential "Would you believe it!" And "What did you just say!"

Nigel

Hi all,

I now have the shortest turnout ever. After some pondering and commentary from Ed, I now have a shorty wye as the entry/exit for 2 tracks using the turntable, and room for a third track to one side. I suppose this is actually a stub wye, or almost a truncated crossover. I just need to add the guard rails. I saw some photos recently of a similar truncated crossover in 12' to the foot scale, used as a space saver for tight locations where the primary purpose was turning an engine. For those interested, Bembridge IoW. There will be buildings on one side of the turntable and a track on the other. Not really necessary of course, but I think it's an interesting detail. No throws, blades or tie bars required. That gives me the 3 tracks I was looking for. I can use the wye or the 3-way at the other end and still have around 3' of sidings.The wye works better, with a turnout immediately after on one side gives me the 3 tracks. Looks like the 3-way gets relegated to the fiddle/staging yard for the moment. It was fun doing the build. Ideal for 3 tracks.

I recycled the frog and closure rails from a Micro-Engineering #5 turnout, replaced the ties with copper clad to make it a wye, job done. I may redo with a #4 frog to give a better separation and an even shorter length. This is a 20 minute job, so maybe tonight.

I used some track I bought at a train show Saturday for the fiddle/staging yard to pose the picture. Code 100 Atlas HO at the top in black, approximately 24 feet of flex track for $6, around $0.75 per 3' section, brand new. It's for the fiddle/staging  yard, no point in spending out on On30 track. It usually sells for $5 a 3' section. Lower 2 tracks are (expensive) Micro-Engineering code 83 HO track, I will use the rails for scratch building turnouts. Code 83 rail is expensive, comes from Micro-Engineering in packs of 32 (96 feet!). OK if you build a lot of turnouts. Cheaper for me to buy a section of track, which normally makes 2 turnouts.

Nigel



Edit 1. Forgot to mention, it is 4" long.

Hi Ed,

Thanks.

Well, I had a few minutes during the Premier League soccer half time this evening, so I got on with the MK-II version of the "shortest turnout". I had pre-cut the sleepers/ties earlier on, so this was just a soldering session.This one is more of a truncated crossover (scissors) like the one that was at Bembridge, just very slightly longer and a tad wider at the turntable end than the first one I built. Better separation of the tracks with that #4 frog though. All that is left to do is to cut some isolating gaps for the frog, and the isolating cuts on the sleepers/ties. I used the Fast Tracks $4 filing and soldering frog/blade jig ($$$, ouch, but it's good for a couple of hundred turnouts - as if!) and their #4 On30 wye template (free download), no guess work. Stock tracks through nicely, so job (almost) done!

I prefer the UK style fabricated frog to the frog casting beloved of North American railroads and model railroad track suppliers. The Micro-Engineering frog rails are also a bit skinny. Their frog seems to be a MAZAC/ZAMAC casting, so soldering is problematic unless I use the right Zn-rich solder and that witches brew of a flux.

This really is an easy turnout to bash or build, and a real space saver if you need a couple of tracks going to a turntable and space is tight. In N/HO/OO/O a wye cut down to the frog and a bit of the closure rails would work, eliminates the soldering. Two minutes with the Xurons and a file to conform the track to the turntable well curve. A regular turnout works as a donor, although the sleepers will be at a funny angle. In On30 it's a soldering job unless I use #5 left or right turnouts.

Nigel

Hi Ron,and

Thanks. However, before anybody rushes in hold off until I do some calculations on the relationship between turntable radius and required frog angles. So obvious I missed it. :oops: :oops: :oops:

Nigel

Hi All,

As I said in the previous post pretty obvious if I had thought about angles and not frog numbers. The frog angle for a realistic truncated scissors/crossover arrangement of two tracks depends of course on the radius of the turntable. In my case a #4 frog (around 14.2°)needs a radius of 4". Fine for 4-wheels wagons, not so good for my small locomotives of around 6.5". There is of course an inverse relationship between the frog angle and the radius. For my radius (3.6") the minimum frog is a #6 (around 9.5°, greater works fine). If anybody is interested I can draw up a table of radius vs frog angle or determine the equation. And there I was hoping for a greater track separation with a smaller frog angle. Fat chance. Looks like a bit more soldering tonight. I have a jig somewhere for #6 frogs.

Nigel

Note: My frog tables are in minutes and degrees, hence the approximate decimal.value. Anything between a #6 and a #7 will be fine.

Hi all,

Interesting feature it could be, but I just looked at John Drew's last turntable post with interlaced track, good 'nuff says I. Just did a bit of measurement, only a tad wider than the frog version, not really enough to make any difference (0.1" with a #6 frog angle :roll:).. Interesting exercise though. Probably works better with a larger turntable.

Nigel

Hi All,

Underwiring/electrickery started, plus some track planning on the top. Seems I can use the 3-way and the wye after all.

Nigel


Turntable end. Left had side is the box for the polarity switcher for the bridge rails (Digitrax), middle upper is the feed to the bridge rails, middle lower is the DCC power bus (14 gauge solid copper and terminal block), right hand side is the box for the PWM circuit plus the 12v power supply (ex-electric razor, 12v/400 mA output). Hanging down is the rocker switch for the motor (forward/off/reverse). That will be put in the side wall. The turntable motor/gearbox is taped in place until assembly. There is a corresponding terminal block at the other end of the board. I tested the motor with the PWM controller, 0.6 RPM in both directions and no cogging.




Track plan (subject to change depending on my mood, the weather and next doors cat). Three-way entry from fiddle yard with a head shunt for the locomotives, wye to engine shed, Mix of HO and On30 track until cutting time. Top/RHS track will pass behind the mill to the fiddle yard (which will be in the mill and may yet be a simple traverser). I may put a slight S in that one and get a bit more space for the workers halt and straighten the entry to the fiddle yard. All turnout switches are away from cross supports underneath. Long-term plan is for a scenic extension 5' long on the turntable end going to the sugar cane fields and equipment. Needs to be on an ascending gradient off the module.

 


Coal gondola (wagon) for the steam engines when being turned. Fuel oil for the diesels will be down by the engine shed.




Two road engine shed.(to be built). Basically a corrugated roof on rail supports. RHS will be the exterior wall of the mill.

Hi All,

Time for a fiddle yard. Simple no frills project, plywood base and top, glue no screws, and a sliding "shelf' on top with 3 tracks that accesses 3 tracks on the scenic module. Each track will hold 4-5 freight cars and a locomotive, or 3 passenger cars and a locomotive. I am waiting for some 1/8" thick UHMW polyethylene strip to go on the top of the baseboard and the underneath of the "shelf". This is low friction high density plastic, and should allow effortless movement. I'm planning on keeping the electrics simple. More on that in the next few posts.

For those interested in this sort of thing: Base dimensions 3' x 15", "shelf dimensions 8.25" x 33", track is Atlas code 100 (brand new at $0.80 each at a recent show, retail is normally $5 each), plywood construction except for the poplar strips, base 0.5" 5 ply, shelf 0.375" 7 ply, 1.5" x 0.5' poplar strips at the ends of the board to locate the shelf and 0.375" x 0.5" poplar partitions on the shelf. All butt joint construction, interior grade yellow carpenters glue (I have found screws unnecessary for modules). Some varnish when the glue has had a week to really set. Time to build: 4 hours (including watching glue set).

The reason for the partitions is to allow for drop-in cassettes if I decide to go that route in the future. No plans on motorizing it at the moment, although If I find a suitable slim-line linear motor that may change.Ex inkjets are often suitable. Had to replace the ink in the current one yesterday: $75.00. New one with ink was on special for $45.00. May have a linear motor and carriage coming up when it's time for ink again.
 
Nigel
