And even more important, wire size of only a bit over 0.001” diameter (1/8” = 0.125”, and 0.125 /87= 0.0014”). Not at all practical. Dan Mitchell ==========

One only needs about 10% hole-to-matrix size to see through something when backlighted. The poultry cars, however are very transparent when FRONT lighted. This requires more like 90% hole-to-matrix

The problem besetting most of us regarding the wire mesh on the poultry cars is not the 1.5” mesh size but the 1/8” wire size. In HO scale that’s only a little over 0.001”. None of the

And I just now remembered that AC&Y had some 33' IL cars I have no details on. David Thompson

I've posted more RPM Chicagoland thoughts on my DesignBuildOp blog. Included are links to resource websites that were discussed in my presentation on Pre-Depression Era Railroading.

All, Thank you all for your input on the mesh! The screen on TWP is really quite impressive and close to prototypical dimension. I did have a chance to look around there a bit yesterday

One thing missing from Kristen’s presentation handout were the brief videos. They are not part of her pdf. I posted links to the videos she used, to this list back in August. Doug

Doug, Dave, et al., Doug said - “In her presentation, Kristen said the mesh on the car at St Louis measured: 1/8” woven wire, 1.5”x1.5” vertical diamond pattern.” Diamond patterns are

Nelson: To get 1.5 x 1.5" openings in HO scale, one could consider ~40 mesh screen with ~0.017" openings. The problem with metal screens for Kristin's application is the wire size -- 1/8" wire in HO

400 mesh specs are 400x400 per in., opening size 0.0013 in. sq., 0.0010 in. wire diameter. This mesh was used for window screed, so it’s smaller than chicken wire. Anyone interested in chicken wire

In her presentation, Kristen said the mesh on the car at St Louis measured: 1/8” woven wire, 1.5”x1.5” vertical diamond pattern In HO that calls for a 0.0172 x 0.0172 mesh Doug

Kristin, I can guarantee that you will be able to find scale mesh on that web site. My 400 mesh was perfect for my horse cars. You could see objects thought it when it was backlighted. I don’t

I downloaded her PowerPoint presentation from the Chicagoland RPM web site. Given that you know the screen size, it should be easy to figure out which mesh size matches. Nelson Moyer

Jake, You can actually get to the complete presentation and handout here: http://trainmodeler.com/clinic-handouts/ Your measurement memory is pretty good. The screen is actually

Nelson, Thank you for the source. I will definitely give them a look. The hard part is getting something with openings small enough to be to scale. Kristin Dummler

Nelson, Where did you she her presentation? I'm one of those whom work kept me from attending. The screen I measured on the existent poultry car in StL, IIRC, is a rather simple welded wire

Thanks to Tony and Ben for your replies. David Payne

Dan, and anyone else interested, I have a copy directly from the Miner organization of one of the 24" hand wheels. If anyone, or any manufacturer, would like a copy, I would be happy to oblige. Gene

I just read Kristin Dummler’s presentation on live poultry shipping, a clinic I couldn’t fit into my schedule in Lisle. It was quite informative and the photos were outstanding. Kristin mentioned
