The 9/32" brass tube was cut with a small hacksaw using the jig made for the PCB plates. The cut ends were smoothed with a file and the burrs cleaned out gently with a tapered reamer.

With all the base plates and tubes cut, assembly of the units could begin.

From the left in the picture are the stages of construction:

1. The PCB plate and the tube were cleaned.
2. Both parts were tinned with solder.
3. The two parts were soldered together.
4. The PCB was mounted on a piece of cork tile giving it a bit of flexibility and bringing it up to the correct height.





I have twenty units to make. I guess I'm lucky I didn't have to fabricate the bolts too! :shock:

As the RFY is a non-scenic part of the layout representing the rest of the railway in Britain (!) it doesn't need to look pretty. It only needs to be functional. To that end the bolts and keepers will be sited on top of the baseboard and table, making it quick and easy to operate. I envisage being able to make several train movements in and out of the station before I need to do a 180 degree turn; most of the movements will just be enough to align the various table roads with the entrance/exit road.

As I fit the bolts and keepers I will take some more photos and post them here. The plan at present is to also do a short video to show the whole thing in operation when it is finished.

If there was anything good to come out of the recent brief unavailability of this forum, it may well have been that I found time to finish soldering up all 20+ keeper bases. :-)

I used a 30 watt electric soldering iron but I think I could have done with something a bit more powerful. The problem was that I needed to hold the tubes in place on the PCBs with the tinned surfaces together. It can't be done using ones fingers 'cos one gets burnt PDQ! I used a large spring clip to hold the parts together and also found that the spring clip would stand 'on end' with enough stability to enable me to carry out the soldering without falling over. (The clip - not me! )

Sounds like the perfect solution, you might think. :?

Unfortunately not. The spring clip, being made of metal, gets gradually hotter and hotter. Apart from becoming uncomfortable to use, it conducts too much heat away from the parts being soldered. Therefore, it works, but it's not ideal.

Never mind. The job's done now. :-)

Thanks for copying this lot across Bob! :D

You really must have the patience of a saint! :shock: :wink:

Much appreciated.

It's no good blushing Perry. :roll: :wink: We can't have our best stuff vanishing into thin air.

On the one hand I too am really glad you have brought this across Bob, because I would like to use Perry's idea one day. :lol: :lol:

On the other I wish you hadn't because it makes me feel so flaming inadequate. :evil: :evil:

I know the feeling Les, and the trouble is this man is only going to get better. :cry: :wink:

Les,

May I just make a couple of slight corrections here;

1) It wasn't my idea. I just adapted it to suit my purpose and location, and

2) It wasn't a difficult build.

I'm no carpenter, mechanic or electrician, but if you break a project like this down into manageable sized pieces, it really isn't difficult. Time consuming - yes, but not difficult.

The planning stage was all-important. I broke the whole project down into single stages, i.e. build the frame, mount the pivot, cut the table, mount the table, lay the track, make the bolt keepers, install them, add the wiring, job done!

Each small stage was arranged with a target I thought I could achieve in a reasonable time - even if it took me more than one try.

When one stage was complete I planned the next one, and so on.

Looking at the project in it's entirety I think I would have been too intimidated to start in the first place, but broken down into it's different stages it turned out not to be too hard at all.

Someone quite famous once said, "Even the longest journey starts with but a single step." I've found that to be true in many ways. Don't be afraid to try. What's the worst that can happen? The first effort goes in the bin? - and possible the second, or even the third, but think how much knowledge and skill you will have picked up along the way! :D

Perry

If you have just read this series of posts and still haven't a clue what I'm talking about (which is highly likely :? ) there is a short video in the Video section (surprise, surprise!) that shows it in operation.

Well Perry, I have just read this all the way through.
I have seen similar objects in various mags but not described as well as you have done.

Yes, it is true that looking at it as a whole, one could almost decide not to do it, but planned in stages, yes , achievable. That is how I am looking at my layout - not as an entire layout but broken down into areas.

Thanks, Ron. :)

It's the only way I am happy tackling most things; lots of planning and breaking down into simple stages.

Are you thinking of building a revolving fiddle yard, perhaps? :wink: :D

Perry, if I had seen this topic back in August 07, I would have considered it to replace my previously small terminal station located in a large aisle.

(I did not join until a lot later)

I have sent your video link to others who are still in some planning stage & if they come back to me wanting to know how to do it, well they will have to join YMR.
