Title: Making a K27
Post by: John McGuyer on February 01, 2008, 09:04:01 PM
I mentioned earlier that I was planning work on a Bachmann K27. I said that I would start a new thread when the project began. Well the time has come and hopefully I can get suggestions on techniques to improve this engine. The first picture is the start of a brass plow in place of the molded plastic one that came with the engine. I will want this piece to eventually look chipped along the front and rusted in the corners. It should be engine black with a metallic sheen. The second photo os my first attempt with Pearwood and Silverwood weathering. It was actually done on a mill using normal mill cutters.

I have to make a second post to get all the pictures in. The first is the smoke stack. This is my experiment learning to use combinations of Floquil paint, MIG pigments and Bragdon powders. I'm slowly finding things that work for me. One thing that seems very effective is that I have mixed a little Bragdon light rust powder in some Floquil flat clear. I can dab this into a spot then stipple some dark rust powder into the drying paint. It gives a very good textured rust spot. I've found that the mixed paint gives me far better control than just using straight clear (which tends to run) and either gives much more control than just trying to dab on the powder as in the instructions.

The second photo is just for information. They are the patterns for 1/20.3 glad hands that are on their way to Ozark. They should considerably improve what they presently have. They of course will be used on this model when available.

This last photo has nothing to do with the K27, but I have mentioned that I was making a Southern Pacific GS-4 from a MTH GS-2, so I thought you might be interested in actually seeing it. Here is a shot of the pattern for the dual light nose. If you look closely, the upper light is actually two lights. It also now has all the hinge detail. This piece is now at Bob's to make a resin casting. That will then be finished and used on the model. We'll keep the brass part just in case we want to make more. Also, you can see the proper front wheels which were turned from brass. This picture was taken in progress and much has yet to be done to it.

Yea buddy, the same great stuff as usual John, I'm anxious to see what you come up with for a snowplow for the Bachman K-27.  It would sure enhance the front portion  and make a universal  engine out of it when needed.......Keep up the beautiful detail work, can't get along without you any more.         Mac

  The heat affected area is very well done, looks like real, I imagine the hissing when something wet will touch it.
  Pity it not possible to give it a little glow.
  Your brass parts are beyond me, when I need some, I'll send a mail ;D

Here's a shot of where the K-27 is at. On the front is the tool box we discussed made of brass covered pearwood. The brass parts do look much better than the original injection molded pieces. I am weathering them, then stepping on to the next phase.

Post by: finescalerr on February 24, 2008, 04:33:45 PM
The toolbox and brass work look superb, John. But you need to stop hand-holding your camera for shots in low light. Everything is blurred. Use a tripod, set the f/stop to f/9, push the button, and wait a few seconds for shutter to close after a long exposure. The photo will be infinitely better. -- Russ

I'll try cnU. It will be very hard to get a tripod in where I'm shooting these pictures. I may have to make something that clamps onto my chair.

They moved the electric car that normally sits just behind me so I had enough room to drag a chair over and sit the camera on my little tripod. Really does help. Shot these at F10.

Here's where we are at. I'm learning to use the Bragdon powders as you can see. It doesn't show, but there is now a Pearwood floor in the cab. Worked out very well. Thanks! Also per watching projects here, I'm doing layers of both Floquil and Vallejo paints and am getting some pretty good chipping and wear effects. Only problem with the powders is that I get the effect I want, but it rubs off too easily. I'm afraid to airbrush over it as I might lose the texture the powder gives.

I'm now making chairs for the engineer and fireman as I somehow don't think they are plastic boxes.

Thank you guys. Coming from people like you who know what it takes, it really means so much. I read over and over your posts and go to all the sites you recommend not just once, but numerous times.

!cnU, I hope you are taking notes for future articles in your Modelers Annual. So much of the info here on this site, is just not available elsewhere.

I didn't think the seat in these things was a plastic box, so I made something. Since I don't know what they really looked like, this is my best guess.

It is a turned brass base with brass strip seat braces. The 'upholstery' is pearwood covered with a handkerchief and painted with Vallejo brown. Rubbed it to look worn. The frame was painted with Vallejo Gun Metal and some Bragdon powders rubbed on to age them.

Oh yes, Thank you Chuck for your info in making knotholes. I added some to the wood beams.

  John,

  this seat looks great.
  I don't know or cloth was used as it wears quickly and picks up dirt easy, I recall leather or plain wood being used a lot in Europe. German steamloco,s had wooden seats and in e-loc's the machinist was standing till in the late 30's / 40's.

I figured whatever I did, it was better than a plastic box. I went through all my K-27 pictures I gleaned off the web, plus went through my K-27 book and I could find pictures of the backhead, but not the seats.

Thank you for your comments.

Well, you're getting mighty fancy there John, idle hands are the devils workshop and you are doing some mighty fine looking work, especially since I have seen you engine in person and know how much hard work is actually involved......keep it up  !   Mac

John,

Not to sound/be nitpicky/disparaging.....but since you are working so hard and doing such a nice job on the loco.....re. the seat:

With the wear/weathering shown on the loco, the seat seems a bit stiff and contrived. Instead of pearwood, you might want to consider something like Magic Sculpt for the cushions...this way the could be molded to show the areas of constant wear use...IE indentations, edge compression, etc.

The fabric texture seems a bit "large"/overscale/coarse.....maybe it's just the photo. A thought would be to use something with a much finer weave like a tea bag or sim. Another thing to consider would be to ise the MagicSculpt, and then lightly "impress" a fabric pattern onto it......an advantage again when doing the putty, is that the fabric seams could then be replicated by a small/very fine impressed line along the edges of the cushion box. ("box cushions" such as those you ghave shown generally have seams at the top and bottom edges....some even have "welting" ).

I also do question the "fabric" for this cushion, rather than a leather, which is more durable.


....regardless, it's coming along nicely.


Marc



Title: Re: Making a K27
Post by: John McGuyer on March 11, 2008, 10:49:56 PM
Yes I agree, the fabric is a little course. I considered putting thick paint then letting some fabric show which could look like worn naugahyde which has that course canvas backing. I did file the edges of the pearwood quite a bit to look worn. I also sanded the material a bit to look worn. The fabric just happened to be laying there as I'm planning on making the curtains from it.

I've taken some more pictures but they are still in the camera across the street.

John

Post by: Nurser on March 13, 2008, 12:59:32 PM
May I suggest the finest fabric I know, which is silk screen nylon.  Any T-Shirt printer should be able to sell you a few offcuts.  Provided bloody computers haven't taken that job over too.

This photo of a Cumbres & Toltec cab interior stolen from Flickr may be some use. I think it may be one of the bigger and even more boring than usual varieties of D&RGW loco, but at least it's a weathering reference and it does show a seat.

All good narrow gauge engines need a shovel to dig their way out of trouble. This is sheet brass with a small piece of tubing soldered on. The handle is a wood toothpick

This platform is something I learned from Marc. It was first painted with Vallejo metal paint, then a layer of Floquil engine black over it. It was lightly sanded to look worn through.

With all that bad mountain weather, the crew need some curtains for protection. This is a white handkerchief soaked in very thin paint. You can also now see the real wood floor.

Post by: John McGuyer on April 27, 2008, 12:17:13 PM
Most sound people do not recommend Bachmann's optical switch and opt for Phoenix reed switch. This mount can move in a number of directions to adjust the location of the switch to the magnets.


Title: Re: Making a K27
Post by: John McGuyer on April 27, 2008, 12:45:52 PM
The chuff trigger magnets are in a brass ring around the axle. Pockets are indexed and milled in the ring and the magnets snap in. The ring is then CA'd to the axle.
