This is a project in the works. I'm bashing the Bachmann 2-8-0 into a the K-27, RGS #461, including
new cylinders, valve gear and all new running boards. When complete, the loco will be a reasonably
accurate model of the #461. The valve gear castings come from PSC, cylinders, rear frame extensions and
rear truck are scratch made. The loco built with this version of the frame extensions, with the rear truck
disconnected from the external journals, will able to negociate a 2.5ft radius curve. The loco however
will not be run on less than 4ft radius curves! We shall update these images as work progresses.
I've been busy working on the K-27, the front end is done, next the tender..
These photos provide a reasonably clear view of the level of work required in turning the Bachmann 2-8-0 into a K-27, full
bash. Basically, the black areas are the part of the model left untouched! Everything else is new, with the white areas
being made from sheet styrene, 1, 2 and 0.5mm thicknesses. The tender is constructed using my typical Masterclass technique
of thick styrene shell with pipe corners, and detailed rivet embossed wrapper cladding. For more info, refer
Masterclass 2001, Chapter 7 and
Masterclass 2002, Chapter 5.
OK chaps, the parts list in adance is this..all from PSC. You can order form Caboose Hobbies, San Val,
Morgan's Big Trains, or direct from PSC. The parts are:
PS-9858 - Westinghouse Cross Compound Air Compressor.
PS-9859 - Westinghouse Cross Compound Air Strainer
PS-9860 - K-27 Pilot
PS-9865 - K-27 pilot steps - single bar support type. (choose this or PS-9829)
PS-9829 - K-27 pilot steps - double bar support type. (Choose this or PS-9865)
PS-9870 - K-27 main rods (optional - use if you want the correct fluted main rods).
PS-9874 - K-27 Reverse Link Cradle
PS-9828 - K-27 Valve Spindle Guides - Use only with Outward Slant cylinders - not needed on Inward Slant version.
PS-9871 - K-27 Reverse links
PS-9868 - K27 Crossheads
PS-9873 - K-27 Crosshead guides
The new sand dome is an Accucraft 1:20.3 C-16 #268 sand dome. The width is good, but the dome is about 2mm too short.
It is the best I could find and has the right look to it.
Be sure to check the K-27 type you're building to know if you need the spindle guides (outward slant only) or pilot step type.
A cautionary note, this is a model of a large outside frame 1:22.5 scale 2-8-2 built from a small 1:20.3 2-8-0.
In making this scale change we are also going from the correct 3ft gauge to a meter gauge, or 3.28ft gauge. The
negative effect this has on our bash is that the outside frames, cranks and rods all sit wider across the model
than they should be. In turn the cylinders sit further outside the loco than they should. The overall width of
the cylinders on our 1:22.5 model will be approx 12mm wider than they should be. When proportioned against the
rest of the model, the excess cylinder width will make the boiler look a little too narrow, the cylinders will
also appear to sit outboard from the running boards. We can't really fix this problem, it is very much just a
part of the bash. Since Walschaerts valve gear was used on both inward and outward slant cylinder versions of
the K-27, you have a choice of two types of cylinder profile. To help minimise the negative effect of the excessive
cylinder width on our K-27 bash, do consider using the inward slant cylinders. Outward slant will only enhance the
problem further. But you must ultimately model the prototype you want to model! William Hemmeter very successfully
build an outward slant version a couple of months back. The model is very very good, but the cylinder width is far
more noticable on his model than it is on mine.
