Sprat & Winkle couplings on Hornby Gresly coach


Recommended Posts

A recent convert to S&W, I'm slowly having a go at fitting my stock with couplings. The layout is not yet operable, so I'm doing this in fits and starts.

I recently purchased a couple of ready made S&W coupling packs, just to get started. The thinking was that if ready made, they would be right, and I could make mine afterwards to match their sample. Having worked through my 1st train - a rake of horseboxes (permantly coupled with simple hook and loop), I have reached the Tail End Charlie. This is a Hornby Gresley corridor brake (actually one of those split from the N2 1948 pack, in BR Brown, if it matters).

My coupling is a full, ready made, S&W loop and hook coupling. I have set the height as recommended, which in simple terms is mounted level with the lower edge of the bufferbeam in most cases. (And yes I do check with a jig).

I have turned over the coach in a cradle, removed the bogies, removed the NEM "swivel" coupling. Plastikard has been used to pack the underside of the floor level to the bufferbeam, giving a flat surface to mount the coupling on. The wire loop of the coupling is about level with the face of the buffers, maybe a tad proud. This makes the outer edge of the baseplate level with the face of the buffer beam. So far so good?

When the bogie is replaced, & the coupling in the "uncoupled" mode (ie dropped, with its tail horizontal and touching the base - fine.

However , in the "coupled" mode (hook horizontal, tail now dropped), it fouls the bogie.

 

What am I doing wrong, how do others get over this? I presume that with other coaches, this fouling is likely to occur. I am following what I believe is the right guidance, to mount the couplings on the body rather than the bogie.

 

Thanks in advance, Stewart.

Hi Stewart,

 

I've had this problem as well on bogie stock,

but they are all a bit different, depends on the length of the bogie

/position of swivel point/and overhang of buffer beam.

 

2 of the options I have used (with varying degrees of success) are:-

 

1) shorten the length of the 'paddle', but don't forget to increase the

weight to compensate (trial and error I'm afraid)

 

2) straighten the paddle, so that it is level when coupled. This does

mean you have to have a longer staple (mounting/swivel point) that

is set higher behind the buffer beam, also you might need to make

a hole in the coach floor. [you also need to put a second/wider staple

to restrict the paddle from dropping down]

 

The third option is to mount it on the bogie, not ideal I agree, but it

might be the only option.

 

Good luck, Jeff

Or mount all your couplings higher, mine go through the bufferbeam, this stps them fowling the bogie on all stock, wagons are set this way too, it sounds unsightly but it is really not to the eye at normal viewing distances. The issue then becomes on r-t-r wagons as some have a false lower floor, but it is easier to cut this away than muck around on the bogie stock. It also makes mounting the wire very easy as it is secured through holes in the buffer beam rather than stuck below it

I built a pair of D & S coaches for the next Ely layout and our S & W maestro fitted couplings to them.  The bogies are right at the end of those with very little room above them.  This is how we did that:

Derek has always put the couplings through the buffer beam and as someone has already said it isn't at all obtrusive.
