Thanks for the vote of confidence Roger.

The £12 fret has enough parts for twenty pairs. Assuming they work well once fitted, I will probably use them on all my goods wagons (which at this stage is not very many at all) which means at least one shunting loco initially.

As for coaching stock, I will effectively use standard couplings to create ‘fixed rakes’ but change the coupling at each end to the new type to allow a loco to decouple in the station, get turned in the yard before leaving with the coaches in the opposite direction.

That’s where some of my trials come in to determine the best position and combination of hooks and loops (I have to re-read the instructions first).
That also will determine where I place the magnets - they recommend electromagnets but I plan to test with permanent ones as well.

To my unenlightened eye these 'bars' seem to be 90 degrees out, as I would have initially thought they would lay flat along the bogie or wagon chassis and be fixed by small self tapping screws or nuts and bolts?
Perhaps Steve can enlighten me
I still have to work that bit out Brian.

I think you are supposed to remove the moulded hook on the buffer beam and push the bar through but Iím still working on it.

Surely they push through a slot where the plastic moulded hook usually is. Through the slot then add a spring then a split pin to hold all in place. Cutting the slot will be tricky.


Like this. Simple!!!

Correct Brian (I told you I would read the instructions).

They do say that they can be held by a spring/pin, although glue is recommended in 4mm scale. The spring/pin route is ideal in 7mm apparently.

I now have a couple of cheap wagons on the bench and I have learnt my first lesson. The wagons I chose were shallow coal wagons from Oxford Rail but I found that they have a large chassis weight moulded into the chassis directly behind the buffer beam.

Drilling the recommended 2mm hole,as there was no slot to push through, was a bit messy. Hopefully the coverplates provided on the fret will cover my embarrassment.

Glue drying time.

Yes the same with dapols chassis, also i would be concerned the coupling height is going to be increased. IMG_5095.JPG

IMG_5096.JPG Im glad to be doing the 7mm version

That weight looks as though it can be removed and a slit cut in each end. The Oxford Rail is moulded in - completely sandwiched by plastic.

Correct Steve its only glued in, i have loads of wagon spares here. ( you may need some before this project ends )

I might just take you up on that Brian.

But we are making progress. This is what they look like fitted and coupled. They simply push together like original tension locks but it is important to get them at the right height and parallel to the underframe. I trimmed the tail on the hooks to achieve this.

Push the wagons over a magnet, permanent in this test, and the hoop pops up. It canít recouple because the latch on the right stops it dropping back into the hook, then just drive the loco away.
But I can see why they recommend electromagnets rather than permanent - thatís the next experiment.

they certainly look well in place
I guess the issue with a magnet is that you will have to shunt the wagons away from the range but then go forward to create a space before going back to hook on as when the hoop drops it wont be on the right side of the keeper where as kadee types would be held open and when shunted back it would close correctly. The electro magnet gets over that issue.
to allow the train to turn will you just fit the same side to the back of the coaches?
