Mossys 3D Models

Tom, brilliant thanks but that's going to take an awful lot of figuring out - tomorrows job. I was aware of the compression being in a cupboard on the left side and I am building this Class A in that, the original state. The curved element to the splashers I didn't know about.

As built do you think they were fitted with screw reverser, lever reverser or a combination reverser. Looking at the GA it appears to shows only a screw reverser which sits below the window line, which suggest the right splasher had an intermediate lever on which the screw reverse sat, am I right?

As always you provide a great service - many, many thanks.

Straight water tanks it is (as drawn), hinges still to be drawn. 'All the elements are shown on the GA but will take some deciphering' - Your not kidding more like un-decipherable or severe brain fade. Just trying to understand things the screw reversable must be sat on a shelf on the righthand water tank, that's the only way the GA makes any sense.

 

Given all the discussions on internal water tank in the posts above, this morning I set about modifying the left hand tank. What should have taken a few minutes became over 2 hour. More practice using pattern on a path required, I could have drawn and extruded them all in the time it's taken. The righthand body in the photo below is the actual tank, the left is a mirror image to show the internal bracing that will be deleted . The doors in the end and top are to gain access to the Westinghouse pump which was positioned in the cab and by all accounts very noisy, which is why a few years later it was moved to the front of the lefthand external tank.

Rob pointed me to a posting on WT primarily about secure ways of bonding brass to 3d prints but also using internal bracing to prevent warping of open resin structures - all very interesting and useful and hence the internal bracing. Next battle is the two step right tank.

 

Right hand tank completed same brace structure as the left with screw reverser plonked on top- I think I am pattern on a path and riveted out for now.

 

With the Westie brake still to do, the front of the cab looks like this:

A very good point that I didn't spot, do you think the screw reverse is stood on the floor, that's the only way it could clear the water tank.

 

Tom,

I find understanding the GA a real &^%$£*. Modifying the right tank to the same height as the left is an easy but boring task, similarly a two handed regulator. If I drop out the existing screw reverse (copied from the Gladiator J21) there is a reasonable gap between the back head and the tank to fit the reversing gear through, which if you are right suggests my tanks aren't wide enough. As your suggesting the only way I can see that the reverser is a height 'to hand' is with it being side mounted on the tank. I will make your suggested changes and lose the existing reverser but hold off any other changes until you have had a chance to review your photos.

All of which suggests 90% cab interior of the Gladiator J21 interior fitting are generic and not accurate for an NER class A. Oh what fun when it will barely be seen!

Tom,

I’m not even going to ask how you found these in amongst the 1000’s of photos in the archive but thank you. As you say plenty to mull over.

As to your notable features

Westinghouse controls, a bulge at the joint between the wheel splasher and the water tank, an oil pot on the splasher side also one of the cab sand boxes – I can see all these and assume the bulge and oil pot would be replicated on the firemans side.

Lever for the cylinder cocks attached to the part of the frames visible within the cab – is that the lever attached to the bulge mentioned above and immediately behind the oil pot also would that be replicated as well?

I can see the fire guard but don’t know the difference between that and a fish fryer, are you implying this was a later fitting.

A couple of other things I can see.

From the top photo.

The shape of the sandbox lid confirms what I understood it to be.

From the bottom photo.

The pipe run on the righthand side of the backhead I assume is the water supply to the clack valve.

Taper buffers, the photos I have of 72 and 490 both of the 1889 batch have parallel buffers, that of 1580 from the 1891 batch has tapered buffers. Does this imply the loco is one of the 1891 or 92 batches?

I did a bit of thinking myself,

Do you know the date of the accident? The other engine involved 1867 is clearly a class O and was built in 1896 so it post dates that and both are in NER livery which would imply a date pre 1923 although I assume these little tank engines scrapped from 1928 onwards were low in the pecking order for repainting to LNER livery indeed did they ever get repainted. Most interestingly of all if all 60 were scrapped post 1926 then despite all the damage this engine was rebuilt and put back into traffic.

 

Hi Tom,

I'm still working through the changes from your early posts but from studying the photos there are a couple of supplementary questions.

What's this pipework taken from the lower photo



Taken from the the top photo, I assume the item outlined in read is the westie, but can you identify the item attached to the backhead and the pipework attached to the tank side, both circled in green?

Cheers 1 down 2 to go! Just out of curiosity I'd love to know more about the accident as it seems to have destroyed the entire back end of the loco but it's unlikely we will ever find out.

 

Been catching up on some of the various bits of cab furniture that Tom has been pointing out and I have seen. The back plate hasn't really changed except it now has rivets all over it. The regulator and westie brake are still to do. The left side tank has been riveted to death but I have spotted more that I haven't don't, doh! End and top cabinets for the Westie have been added and finally the extension cut out has been done, other than rivets done (for now). And then on to the right tank, all the rivets done including a row of 3 I spotted this morning along with what look like two nut heads which have also been added. Most of the morning has been been spent working on the tank extensions, the basic shape and small oil pots were easy, the rear sander levers have taken a long time a combination of ineptitude, guess work and photo interpretation. I'm still not happy with it and may well have another go. Studying both crash photos it seems to start as straight bar which is curved to clear the lower extension and then transmogrifies into rod and finally into tapered rod. All this for something which will be barely visible, I must be mad - tannin, nicotine and food needed before any more is done.
