Stock Car build for my cattle line.

I have plenty of photos of the ones Puffing Billy use, and from an appearance point of view I think your on the right track.

I know I took measurements as I was going to make some, but can't find them. Probably scribbled on a piece of paper that ended up in the bin. I was up there today could have checked if I had known.

Yep! That's what I'm going for. Thanks.
I reprinted at 100% "G Scale" , and it fits between the needle beams quite nicely.

Looks good - but why does it remind me of a sausage dog wearing a bobble hat?

I managed to dig out a drawing of the VR ng 25' underframe that Grant showed in his photo. The VR used that underframe on all their ng goods stock and fitted it with a Westinghouse 6" combination cylinder.

Overall length of the assembly from the piston rod gland to the triple valve works out to about 62mm in 1:20.3 scale.

Hope that helps. I've never gotten around to fitting brake cylinders on my bogie rolling stock, although I've got the drawings and a pattern stashed away. The VR tucked the brake gear up under the floor and on the low slung ng underframes it isn't very visible from normal viewing angles.

It does help, thank you. 62mm is exactly what the cylinder that I printed at 111% came out as. Although the regular print at 100%, which is 1:22.5 scale, looks like a better fit between needle beams.
Hmmm.. more decisions....

If you scroll to the bottom of the page on this link, you'll find three photos of the sort of brake arrangement you are talking about fitted to a Labelle HO wooden kit of a ng freight car. The photo you posted of the 1:20.3 cylinder looks about right.

There's some useful online references on brake systems listed as well.

Thanks Graeme. I was also looking at an old Railine stock car kit in HOn3 that I forgot I had. Very similar.
Not sure how much detail I'll put into the brake system but it needs something up under there. I'm building simple brake beams for my trucks as well.
Thanks for the help.

I didn't like my choice of the brown paint for the Series 300 Stock Cars, too chocolate. I changed to my own flavor of Tuscan Red. The 200 series box cars will be a little more red than this.
Making a little progress on the prototype, mostly with the trucks. I'm finally getting the printer up to speed w PETG, my aftermarket stand alone bed heater made a world of difference.
I'll sand and add a coat, then the decking needs to go on before the body gets mounted then finish the ends with 1/32" scribed sheeting.
I've also been playing with some printed 4' passenger trucks for the railways 26' passenger equipment. They're a Jackson and Sharpe converted from 32mm to 45mm gauge. I also had to re-scale them to 97%, they wouldn't quite fit the printer bed. I hope that it's not too noticeable.
I was hoping to have this prototype finished by now, but between the fencing and other homestead chores, I only get an hour or two a week to be a railroad tycoon.

Coming along nicely.

Those bogey frames look great, I wouldn't worry about it.

Thanks. But I'm afraid I didn't explain that very well lol. The frames that you commented on are my 3'7" freight truck frames, they're a full 100% to scale. The frames that I had to reduce to 97% are the passenger trucks here in this attached photo. I haven't had time to get them cleaned up all the way. These print with a coil spring but I cut them out with a jewlers saw, didn't like them.
The second photo is a comparison between the freight and passenger frames. Sorry for the confusion.

[Old Man Aaron]

Ah, now that I go back and read it again, I see my mistake. I should stop reading the forum last thing before bed!

I see printed coils on those frames would be impossible to clean up. Your handmade replacements look very good.

Thank you sir. Now, to clean up those passenger trucks . They print sitting upright instead of on their backs like most other trucks, so they are support HEAVY. I'm not a programmer but I'm sure there's a reason for it.
The freight trucks, like the ones for my box and cattle cars, print on their backs and clean up pretty easily.

Got some time last week to get the decking on and done. Needs some cow weathering.
In the mean time I'm going to get going on the underside before I glue/screw the body on.
While I'm working on the underside of frame, I may start my next build. I'm deciding on starting either a Combo Baggage/Coach car, or box car or possibly a functioning drop bottom ore car. The ore car has a lot going on and I really need to work the bugs out of it. The Javelina Gold Mine requires several of them, I'm thinking their length will be somewhere around 20 footers. But then again I've been staring at all the passenger equipment needed for regular service too. Either way, I'll start a new thread for whichever route the shop decides.
Bottom pic is just a test fit.

[Old Man Aaron]

Hard to know where to start, I find it best to just pick one blind.

Floor's looking good.

[LNR]

You will be able to do a lot with that floor weathering wise. Did they use lime wash for cattle trucks in the States?
Nice job so far.

Thanks. And I'm not sure what they used. I just look at pictures and imagine/ wing it.
It will need a lot of poo weathering though,

Yeah! very grey from constant hosing out would be a starting point.

Had a few hours today to knock some things out on the prototype.
-I touched up the underside paint and installed some threaded inserts (#4-40) into the bolsters so there's something substantial to screw the trucks to. Also, clearance drilled the bolster pads that sit between the trucks and the bolsters. They'll get glued in place, should be pretty ridged once sandwiched with the 4-40 machine screw.
-Located the queen posts, which consist of a 1/16" brass eyelets and 1/16" X 1/2" cotter pins. Drilled and test fit.
-Also, bent the truss rods to mate the queen post assemblies together to the frame.
Next I have to assemble and mount the trucks to the frame. They were also primered today for final sanding. Once that's complete the end beams can be notched for the couplers once it's determined on final ride height.
Question, I was thinking of flat black, plus weathering, for all parts underneath. Including all brake hardware, truss rods and trucks to keep the model from looking a bit mundane?
Anyway, hope to have some more time this weekend, want to get going up top.

Coming along nicely.
I always squash my split pin eyes in the vice to the size of the wire I'm using, just a small point.
