Bill, I'll be very interested in what your 6k printer can do.

Yes, HO1:87 on both counts.

Here's the part design, 63 lines of OpenSCAD code.  All the dimensions are actual inches, for an HO scale part.  Still need to put in the piping interfaces and the nut-job on the crown.  I'll also print the mounting bracket, but I think I'll do the piping in some sort of soft-metal wire.

The structures remind me a lot of the old TImberlne Scale Models pre Campbell buy out.  I have the entire Timberline Kit line that I use as patterns once in a while.  I also have their casting which were much finer than the Campbell line and a lot more variety.  Some of the tall window and other detail castings have never been reproduced by anyone.  In addition they had a kit which if you purchased 4 of their regular kits they would send you for free.  It was a wooden turntable kit.  I also have that.  When I was a young teen back in 1962/3 I was purchasing those kits, which were ahead of their time by at least 20-30 years, and were based off "real building".  It kind of reminded me of the wood building town that was made of old building brought together south west of Denver Coloriado.  It was never a real town but the buildings are open with full interiors and even has a Masonic Lodge over the Drug Store.  I found it totally by chance on a drive. "On the edge of Fairplay lies South Park City, an extraordinary museum with 40 historic buildings. It was created in the late 1950s by a group of citizens concerned that the old mining and ghost towns of Park County were being dismantled and destroyed. The group recreated an 1800s gold mining town. Buildings were brought in from the high gulches of the Mosquito Range and from mining towns such as Alma, Leavick, Buckskin Joe and Montgomery. Most of these buildings showcase an array of period furnishings and equipment, and tours take you back in time to South Park's early days".  This is a must for anyone who is building scale old west or mining period modeling.

Glenn,

The 168 project is in HO scale, correct? And the print shown is also in 1:87 scale?
VERY Impressive!!

Quite impressive!  I have high hopes for the Anycubic 6K printer I just
unboxed a couple of days ago after seeing your results.

Just printed the first part of my D&RG #168 project, a rough version
of the compressor.  I was particularly worried about how a 4K resin
printer would resolve the fins on the cylinder; they show up just
fine, although the white in the gaps is due to my failure to
completely dry the part after washing.  I now feel confident to add
other details, as I know they'll show up.  Here's a pic, part posed on
1/4" graph paper:

Or tungsten welding rod which adds a little more weight. 1.6mm (not sure about the Imperial equivalent) fits between the center sills of RailLine cars. Not cheap and not easy to cut either but an inconspicuous weight adder.

Thanks. I will definitely try the rail. It already seems to have a minor bow 


Re: D&RGW Wheel & Tie Car

If that wheel & tie car is the Robb/Grandt styrene kit, you might want to consider gluing a couple lengths of code 70 rail under the floor, between the bolsters.  Either that or go very lightly on the nylon truss rod tension.  Otherwise the styrene frame can develop a considerable bow over the course of a few years.

Jake,

Don't know. Its the 15mm Minebea that has six poles. I've ordered five of this version and as soon as I can rip one apart I'll post the result. Either way it's got be an improvement on the original.

Re: Blackstone K-27 motor wanted/needed

I believe the Bachmann motor swamp has already been investigated and those who have thought to have gotten close have, as you have found, not got there. The truth may be that there is no readily available 'drop in' replacement from Kader otherwise why would not have BS bought up the whole bunch. I recall my conversations with Jeff Johnson at BS that this was a motor designed specifically for the 27.
I wonder having shown us the picture of the chinese and BS motor what have you done to try to adapt the motor to the 27 sabu/ cradle or vice versa? You seem to infer that if it's not a drop in then that's as far as you go  Some suggest a Sagami 1220 as a drop in, I've not tried it and anyway those motors are as rare as rocking horse shit.
Zook, if you find the prospect of remotoring is buggered by the motor being too fast (might be as I don't know the 12 volt rpm of the original - just turn the throttle down) or that the terminals are in the wrong place, I suggest handing the issue over to someone more familiar with the problem.

Thanks for the tip Mark. I bought some to replace on my two Ks that I'm going to rebuild. One already has a TSU2 in it so I removed the chuff cam already but the 1st gen motor is no longer working. I will be rebuilding the other with a TSU2 also and a new motor. 
One thing I couldn't find is wither this is a 6-pole motor. I assume it is.

Re: Blackstone K-27 motor wanted/needed

Mark Kasprowicz
 

I think I am going to stick with the Chinese motors at least until I have tried them. The very basic nature of the originals doesn't urge me to consider a motor from the same source. Fitting the Mashima 1220 was not really a complex business but once you've done one then the rest should follow more easily except in my case the supply of Mashimas dried up. So back to the start. If this latest proves unworkable -the search restarts .

Thanks George!  That's a great idea.  

As for the motor found on eBay, besides the speed being different, the leads are in different locations as well.  The leads on the motor in the Blackstones are offset on the corners of the flat side, not on the end.  The leads on the ends will make for some tricky fitting in the frame.

As always, I appreciate your responses and suggestions.

Something to consider in the search. 
As these locomotives were originally manufactured by Kader in China which is a Bachmann partner the motors could very well be similar.  Bachmann has a parts website to explore for a potential replacement. A good choice to start is diagrams for smaller locomotives and diesel switchers.  I did do some research in this as I have part's out a few Shay locomotives in the past. I have some motors from these in my  collection although they are close but not the same.

Dave,
Read the spec - the rpm at 12 volts is 9900 - the figure you quote is for 24.

Re: Blackstone K-27 motor wanted/needed

The casing looks very similar but the speed is much fsster at 12 volts - 9900 versus 13500 - I would hope that the slower motors' torque is higher but no telling of course.

I have some  of these motors in question that I ordered several weeks ago.  They are not the same in size.  Attached are some pictures of the Blacktone and the Ebay item.
