I have one on a converted Minitrix dock tank chassis (middle wheels removed) but doesn't look as good as yours!

I think that's one chassis that I'm not at all fond of - they wear like hell. The Arnold unit intended is definitely superior (even if it is 45+ years old!).

 :smiley-laughing: I ALWAYS profess to know nothing. It makes for an easier life!!!!

It, like the Caly look ABSOLUTELY FANTASTIC Alan, another 2 wonderfully crafted pieces by your good self!!!

Surely a Zimo mx617n would fit under the cab floor  :o

@thebrighton mentioned the extension of the cab to fit the chassis, is that the little box on the back??

That looks the perfect size slot for a chip  :hmmm:

But I'll say one thing, I never believed I'd be name dropped by the good Dr himself  :o :D

That's far shrewder than it might first seem.

None of the above - the motor is large and takes up all those spaces. The place a MX616F would almost certainly fit is on top of the motor in the cab roof area. Tight, but the chassis surprisingly friendly as the motor is essentially completely isolated electrically from the chassis, wipers (that could be removed) provide the connection.

Alan

Re: Dr Al's workbench - 6202, 75xxx, and EM2

Well after a little breather in posts, it's probably time for an update.

Plenty of repairs on the go in the last month or two, but also progress on a number of workbench projects. The first is the Standard 4 - the tender finally completed on this, after fitting the last handrails. Front end of loco is next for detailing attention and hopefully this can progress to paint.



Second (double) project is an unexpected one (pair). I obtained a rough BH Enterprises kit for the LMS turbomotive 6202. Something I'd get to (I thought) as it was part of a batch of other more rare models. Cue another buy a few months later, and I managed to end up with another similar kit in box! As such I've started on a batch rebuild of both. One in standard, simple, unmodified condition, and one to be done to modern superdetail standards.

The first, looked like this - and the chassis was added from spares of a Farish Duchess, as was the LMS tender (Black 5/8F tender is correct for the real loco):



After stripping, cleaning up, and rebuilding, the model started to take shape. It also has a long wheelbase LMS front bogie from N Brass fitted:



This is in original condition, with domeless boiler which means the only correct livery is LMS Crimson, which has started to be applied:



It is now awaiting decals. The other model has had more of a heavy workover. To use current standards, I found a damaged new tooling Duchess chassis as a donor - this had lost the rear peg to attach the tender, but this has been worked around. This type of chassis offers considerable challenge with whitemetal body, as one side of the chassis needs to be electrically isolated from the other, so only one side of the chassis can touch the body. This has been overcome with considerable grinding, but inside the body, and to the chassis. Tender is the same source as the above loco - a Farish black 5, though this tender had already had the handrails neatly removed and holes drilled for separates by a previous owner, so perfect for this.

The chassis also has had sheet plasticard fitted to the side that needs to be kept from touching, as well as a N Brass bogie, and an older tool Farish Duchess rear truck, meaning the older type tender drawbar can replace that missing on the donor:



The loco with new handrails fitted, dome fitted (I need to move this back - it's not in the right place), the original dome/topfeed re-shaped, and the front end with new buffers:



The chimney is Peco Jubilee, but may be a bit tall.





Final ongoing project is an EM2 3D print build for @BramptonBranch . This has primarily concentrated on chassis to date, as well as clean up of the 3D print (which is a nice standard, but still has layering):

Chassis is derived from Farish 31:



Body is going through the passes of primer/clean up/primer, and is getting there. This is the part of 3D prints I most dislike!

Rough:



Better:



Lots going on!

Cheers,
Alan

EM2 has gained roof gear - primarily her horns and pantographs.

Horns were made up with N Brass turned horns, soldered to some shaped flat sheet to give a viable mount:



Pantographs are Kato. Not quite perfectly scale for EM2, but close enough. These needed a bit of tidy up as they had come off something else previously, and had glue and previous attachment hindering their motion. Some repairs later, they now stay up - always desirable.

Alan

Brings back great memories of my Tri-ang 'Elektra' EM2 with working pantograph and all the catenary bits and bobs I had. I just wish RTR N gauge EM1/EM2s were available.

Well, what a month or two the world has presented us with. Personally, this has, until the last few days somewhat castrated my workbench, with the need to move to work from home and getting instantaneous space to do so, which colonised the working space.

Some rearrangement (and long overdue tidying!) later, the 'office' is now somewhere else, meaning the workbench can return, and at these times it's more necessary to have available than ever!

To start with, I've knocked off a quick and easy project that's been knocking about for a while. This Black 5 was obtained some time ago in mediocre running order. The usual problems (minor valve gear adjustments, the loco-tender drawbar, and traction tyres) were put right, as well as the Farish detail parts added (vac pipes, coupling hoks, draincocks and larger wheeled front bogie). It's a tidy model, but LMS....



...generally I stick to BR era. So a renumbering job, and this showed a couple of interesting points. The new Farish black 5 has actually had the body tooled twice - Farish have done both the earlier 'domeless' boilered variety (this) and the later domed type. I'm not sure anyone's publically given Farish any credit for this!



It does mean choosing numbers needs to be done with care - early locos only had the domeless boilers, and while there were obviously swaps during the locos time, they were in the minority. "The Power of the Black 5s" provided a suitable candidate, 45075 in BR clean unweathered unlined black.

So a quick clean off of the printed LMS numbering and lettering (back of scalpel blade) and a renumbering followed. One part that the LMS loco does not have that was added was the BR AWS reservoir tank. This was added from an N-brass part, with the small pipework soldered on from wire.





This brings it into the running fleet, and it's nice sometimes to get a fast project done to completion. Over the coming time I intend to make much progress on many other more complex projects, and those already started (EM2, Std 4MT, 6202, and several others).

So far then:

Lockdown tally of new projects complete: 1

That one looks really good Alan...very sharp indeed!

So how many more projects do you have in the pipeline? If you get bored, I can always send you a few more locos that need some of your tender care ;)

Excellent renumbering job Alan.  I am very impressed.

Kind regards

The next project was an unexpected one - tidying through stuff to sell, I came back on a Farish Scot that I'd obtained a while back. I've always rather liked this particular iteration, with with its 'weathered' finish. However, I already have an identical one in the running fleet. So sell then....?



Initially I thought yes, and add to the stack for selling. However, a thought occurred when finding parts from a Farish Jubilee. One loco that Farish have never looked at doing is the Patriot. In particular, the rebuilt Patriots are basically identical to the Rebuilt Jubilees, and the Rebuilt Scots, with one notable difference - the cab. The Scots retained their original Fowler style cab, while the Patriots had a Stanier cab replacement. Otherwise they are almost identical locos, with the same boiler, smokebox, deflectors, etc.

So, can we make a Patriot from this Scot? Fortunately, Farish made the cabs on all the Scots, Jubilees as a separate part (one wonders if they conceived doing something similar) - so with a Jubilee cab, we can get 90% of the way to a Patriot:



The cab is held with one screw, so easy to remove once that taken off and the cab tugged off (it clips around the firebox).



One immediate issue were a load of gaps around the base of the splashers, necessitating some filling up:



This gives the cab front looking something like this when loose fitted:

  [/url]

[Some horrible glue marks there on the original scot that'll need cleaned up]. Also, about 1mm of the internal cab floor needed removal to fit the Scot body.

After sanding and painting in just the front cab surface, with Phoenix BR green (which luckily seems a perfect match):



This just leave some minor details to remove (e.g. the tool/sand boxes on the footplate ahead of the cab), and renumbering/naming. One problem here is that most of the Rebuilt Patriots had flat sided welded tenders with no rivets; unlike the Scots. One could replace the tender with that from a Jubilee, but I opted here to change the number to the only Patriot that appeared to ever run with a rivetted tender - 45536. This is a good get out of having to sacrifice a Jubilee.



Now the loco just needs the cab weathering down to match the base loco, and nameplates obtained and fitted when I can get the chance to do so. One area I may change is to file down the angle of the front frames, which were a linear slope on the real locos as compared the Scot which curved down to the footplate at their tips. But this will be awkward to do with the amount of other details in the way.
