OT Dean I have five O scale RTR bobber cabeese (1 AHM, 4 Atlas) I’m going to redetail and I want to add Type K brake cylinders. O scale is big enough that you can actually see details like brake rigging, but since a toolbox blanks off one side and the Atlas cars have brake shoe and bracket castings, I only feel it necessary to install brake cylinders and reservoirs. I vaguely remember a drawing in MR or RMC, back in the ‘70s, but lost most of my magazine collection in a disastrous move, so I can’t hunt it down. All I really need to know is whether the usual reservoir/cylinder combo was mounted or the two were disconnected and mounted separately—and how they were positioned. At 76, my memory “ain’t what it used to was,” so I’d appreciate any help I can get. Model Railroading is Fun! Deano
if you can come up with a year i have both of them for the 70's, but looking through all of them would take more time than i have at present.
The KC-type brake combined the reservoir and control valve and piston in a single unit, like this...
...while the KD-type used separate castings for the control valve/piston and reservoir...

Thanks, all. I'm using Grandt Line's castings, which has the extra parts to separate cylinders and reservoirs, so that's what I'll do--and put the cylinder near the opening opposite the toolbox, probably with a lever in the piston rod's clevis. The rigging for bobbers was more complicated and compact than house cars, and since you can't see much of it when the car's on rightside-up, I figure that'll be all I need.
This is like cab details on steam locos and interiors of passenger cars: I've done it in the past (in my salad days!), but life's too short to spend it putting in details you can't normally see. (I never built a Pullman with Walthers' interior details, but even in The Good Ol' Days, I questioned the need for adding "hoppers" and corner sinks to compartment "facilities.")
"Model Railroading is Fun" still applies if you're building stuff for your own shelves in a studio apartment!
Thanks again.

j. c., after I saw Doctor Wayne's reply, with his excellent photos, I decided I wanted to see the actual pictures that accompanied the MR Clinic reference. So, I put on my reading glasses and dug out the thick envelope of Model Railroader indexes, which I kept after I lost most of my magazine collection (pardon me while I sob into my elbow).
I did remember correctly, as shown above. It was, indeed, an article in the Clinic, "Brake rigging for old-time 4-wheel caboose," on Page 163 of the February, 1979, MR. Like I said, I think the cylinder from the Grandt Line K-brake set would be seen through the opening in of an Atlas or AHM bobber truck, and I'd cap the cylinder and place it nearby--all painted Grimy Black, of course. I think I remember now where the handbrake chains and rods would go to each end on a simple four brake shoe setup, but I'm still unsure where to put the reservoir. It's awfully tight quarters under a bobber, what with the lever system and the toolbox!
I know MR will photocopy articles for customers, but I don't know how to go about it (maybe Steve Ott could coach me) or maybe somebody will know how to copy it out and add it to this stream. At any rate, thanks again for your help, j. c., "Bear," and Dr. Wayne.
Happy New Year, everybody, and keep up the good work.
will dig that out today.

I believe Kalmbach/MR has discontinued that service now that they offer the all-access pass digital archive of past issues.

Deano got it, the drawing is for a A/B system with no air tank if you pm me your email will scan it and send it to you.
Pardon me, j. c., "PM?" I know there's a way to connect with members via email, but I can't figure out how it's done: all I get when I query is a list of posts.
Can someone clear this up for me? Sign me:
