Title: Operating Diaphragms
Post by: WTierce1 on July 02, 2014, 02:28:59 PM
I was wondering about how to add operating diaphragms for some of my Bachmann Heavyweights and full dome cars. I have looked online for some options but wasn't sure about any of them and figured I would ask because I am sure someone probably has some experience. I use 22" radius curves just in case that makes a difference.

No idea on what info you have so far, but the below link might have some useful links to store in Favourites.

I have looked around on Google and found some options and a few that said they were for Bachmann but have no clue how or if they will actually work.

I found these that were amazing but have no clue if they would work: http://www.hitechdetails.com/Catalog/cfm/catalog-htd.cfm (http://www.hitechdetails.com/Catalog/cfm/catalog-htd.cfm)

I found these that say they are for Bachmann but don't know how they actually work but the turn radius looks promising:

I also found these which look good:

American Unlimited puts out a great diaphragm; they go together easily, and function more greater... The one issue you will probably have-and passenger cars, especially heavyweight-is going to be the swing.  you will probably have to keep some distance between cars, which will probably detract from the looks. 
You know, getting access to some good photos of diaphragms and passenger cars in areas of function might help.

I don't think that the swing is going to cause them to have a problem, but I know that they will definitely have quite a bit of slide side to side when they are together. This first one in the cars in a curve.

I also found out one of the links to some of the diaphragms I found took you to the wrong place:

I hope that this is what you meant! Thanks!

No, they are 22".
