Big 'Keef at Beck Bridge

Salty Seagull looks on as the Keef K30 poses on a Kato 11-109 chassis giving an idea of how this loco could look if used in O9...

With a few tweaks and extras such as the front grille, bufferbeams etc it would make a quite passable O9 loco, certainly for a modern tourist line. In freelance form, not trying to claim it as a genuine Keef product you could perhaps try a different power source, such as a Bandai short bogie chassis or even the Farish outside framed 08.

Big 'Keef

I received this new Alan Keef K30 print from A1 Models a week or so as John Flower felt that it might be suitable for O9 use. With a few provisos it isn't bad for a maximum-width O9 loco, 28+ mm wide and 43 mm tall when sat on a Kato 11-10. In fact I think my green Knightwing bash might have been a similar size a few years ago. 

It is difficult to see in the pictures in raw form that it is print with a rough finish (it is incredibly difficult to photograph in this form too!)

I thought I would show the stages of finishing the print to a ready-to-paint state. Firstly the raw print was bathed in white spirit to degrease, then washed, dried, and the surface sanded with 400 grit. Then washed and dried again.

(Note: All sanding used home made sanding sticks  made using wet and dry stuck to lolly sticks/coffee stirrers and was carried out wet.)

Red plastic primer was sprayed onto the model - this tends to highlight the surface and the print looks really rough and gritty.

More sanding followed, this time 800 grit sticks, then washed and dried.

A coat of yellow filler primer were applied, then another sand with 800 grit, revealing that a second coat would be beneficial. 

After the second yellow coat I sanded with 1200 grit to the state seen here. Washing and drying occurred again after each sanding session (of course!).

Finally, grey primer has been applied to my satisfaction, giving a smooth finish with only a few minor imperfections. I have managed to achieve this with no loss of detail on the print, luckily it is mostly flat surfaces and angles, with no fine detail.

In all I think about 3+ hours of work went into finishing this 3D print to this state, broken up over several evenings and waiting for paint to thoroughly dry before sanding. I ask myself if I could have built it in less time from scratch, and no, I couldn't.... at this stage I think that it may stay in grey primer, it isn't really the locomotive I need at the moment, but at least it is making me think about what is...

Homeward Bound

With the passengers long gone for the day, and the light fading fast, a short works train formed of an Alan Keef K12 and one wagon heads back to base over the Beck Bridge...

(in reality I've fitted a new, more appropriately clothed driver to the K12 and re-fitted the original generator load to my 1-plank wagon.)

2020 Hindsight

With the end of 2020 in sight the O9 Keef has had a few jobs completed on it and to all intents and purposes is considered "complete" enough to be sat in the display case. Since the last set of photographs I have added (and weathered) glazing, lightly weathered the loco and fitted MicroTrains couplers. These were the first set of couplers I had assembled for some time, I had forgotten what I was missing out on...!

One thing I haven't made any attempt to do is secure the body to the modified Bachmann chassis, it will likely be a blu-tac job. A reminder that the basic 3D print for this loco it available from A1 Models on eBay - and that I have made several changes to model, especially around the underframe.

There is an air of indecisiveness about the future of the model, it almost, but doesn't quite fit with my plans. A bit like 2020 really... I'm really happy that I have been able to continue modelling throughout the year but with hindsight, what has emerged is something of a mixed bag, a collection of individual models that actually achieve no real collective "whole". I started in this vein with MG Models 'Classic' loco, two paint jobs later and whilst it looks OK it might not be what I really want it to be.

Of course 'Beck Bridge' had a makeover to include a backscene, as seen above, which whilst successful it has still not found a real home for display!

At Easter, with time on my hands I started a micro layout based on Julian Andrews brickworks plan, this has never got beyond the initial phase other than a few tweaks as I searched for a suitable aesthetic for the rolling stock, and failed to get the result I wanted using KB Scale kits (nothing against the kits - just how I wanted to use them), and then some doubts over alternative scratchbuilds.

Not everything has been inconclusive, a Meridian Models Ashover coach kit received as a gift actually led to the one completed project of the year, the 009 diorama 'Humberston'. What started as a plain Manilla build of the coach in original condition turned into a customised rebuild of the coach to represent the LCLR modifications and a Simplex scratchbuilt to match, along with a suitable display base with platform and signal.

I hate to admit it but the other real success story was also 009, although the door is open for an O9 reworking for next Christmas!

Don't worry, I'm not about to rename the blog, plans are slowly coming together to revive the O9 micro layout and the locomotive and rolling stock aesthetic might also be resolved. Watch this space in 2021!

Happy New Year to our reader(s)

Alan Keef K12 in O9 - Everythings Gone Green...

With a dry spell of weather over the weekend I managed to get a coat of varnish over the ever-so-slowly painted Alan Keef K12.

The green is Halfords 'Meadow Green', but you might have guessed that! Black and red areas were brush painted, red first over red oxide primer and then the green and red were masked off for the black to be painted.

Grilles are some old etched fencing panels cut to shape, blackened, painted and added in between painting and varnishing. The cab side panel has not come out too badly in the end, although this is somewhat helped by the very flat finish the Humbrol varnish creates.

There are a few jobs to complete such as glazing and I think it will definitely need some weathering to hide the ropier parts of the paintwork. It might have to wait though...

Alan Keef K12 in O9 - 3D Print Manipulation

I haven't managed to get much modelling done over the last couple of weeks, but I have managed to tweak the 3D printed K12 a little to better reflect the prototype. 

Having removed the original axleboxes and smoothed away the remains I added 20 thou styrene behind the frames cut to the correct shape, and then 40 x 30 thou strip to build up the depth below the axlebox positions. The bottom of each buffer beam gained a 60 x 60 thou strip. Once set in place these items were shaped to suit and Milliput used to fill any gaps.

New axlebox and spring detail is formed using various sections of styrene strip, the springs being much thinned down rod. I did try to scribe a spring effect onto this before cutting but it remains to be seen whether this will actually show up.

The grilles caused some fun and games as I initially thought I had no suitable square pattern material in stock. In the past I have used old sections of A1 Models chain link fencing etch for this but had nothing the right size in the usual place. Thinking that I had some fresh pieces in my 4mm scale scenic stash I was stumped when I couldn't find them, it was only when locating the diamond pattern etch I'd used on my 1/24th Lister that eventually found the spare length of fence!

The coupler blocks that I created a few weeks ago by laminating together styrene sheet and strip have been located at a height to suit MicroTrains couplers. They are drilled to allow a 1015 coupler to be secured with a screw from underneath. Bolt head detail is from EDM Models

On the front end I have added slithers of Plastruct hex section to represent the bolts at the top of the bonnet front. 

At this stage rather a lot of paintwork had been rubbed back, and I did have a concern that in places the primer had not adhered to the rubbed-down factory finish. Several edges saw the paint chip away all to easily... After a good scrub down I applied a very light coat of primer as a proof coat and also in the hope that it dried better as a thin coat. After a few more adjustments another coat was added and the end result was this.

 

It's a bit rough in places but it will have to do, and hopefully painting and weathering will distract the eye a little. I've now given it a rub down with 1500 grit wet and dry in preparation for a sprayed coat of green, I've chickened out of Keef factory applied orange!

If you fancy an O9 K12 yourself, A1 Models have the print listed on eBay here...

Alan Keef K12 in O9 - Take 2

"I have a bodyshell I have adapted from a commission job that may be of interest." So began an email discussion from John Flower at A1 Models, in a later reply he said "The body I am sending you was done for a customer in 7mm scale for him to fit a chassis. He isn't doing O9 but it would be used in these gauges." The resultant parcel that arrived a few days later was opened with a mixture of excitement and trepidation, as John had described how the vendor he is using for printing now offers the prints ready-sprayed in a semi-gloss finish.

There it was, instantly recognisable as an Alan Keef K12. Those with long memories may well remember that I scratchbuilt one of these nearly ten years ago, then regretfully exported it to the other side of the globe! 

I'll have to admit, that on first impressions the finish didn't really grab me, but after about 3/4 hour of smoothing using 400 then 800 grit wet and dry, I had flattened off most of the finish. Certainly different from finishing raw prints with cycles of filler primer and smoothing, but with hindsight I would perhaps rather have that level of control. It is worth noting that the print is actually in a black material, apparently this is unpopular with some customers, are they conditioned by what Shapeways churns out? Personally I cannot see anything wrong with it....

Getting adventurous I marked up and scribed in the lines denoting the upper edge of the frames and buffer beams, and the panel join towards the front of the bonnet using an olfa (style) cutter. I also created some extra clearance inside to allow the body to sit on a much modified Bachmann Plymouth chassis.

When I say much modified, I mean filed and cut to within a millimetre of it's life, and converted to 4w in the process.

Compared with the drawing in the Alan Keef book, reduced to 7mm scale, the print is about 5mm too long and 3mm too wide, understandable as it was intended for a 16.5mm gauge mechanism. The other main area where the print differs visually from the drawing is in the bottom edge of the frames and the axleboxes.

A coat of grey primer allowed me to better judge the finish I had achieved. Unfortunately the printed bolt heads on the cab side panel didn't look as happy as I had hoped they would and I will be looking to reduce these considerably before going much further.

I'm also looking into modifying the bottom edge of the frames, as I would really like to add the correct shape by adding small fillets at the bottom of the frame and also to add depth to the bufferbeams. This will also mean that I need to alter the axleboxes. As printed the front one is not the same distance from the front as the back one is from the back (and they should be the same), altering this will actually make it match the power unit and better reflect the drawing.

More when some progress is made...
