well i am looking at re powering a set of brass E units, (the A unit is/was powered, bad old open frame motor, the B unit is non powered) using a couple of athern sd frames and running gear. but the athern frames are a bit short, (not even a 1/4 inch) is there a good way to add in a bit of length with out just () up the frames. as would like them to hold together, no flex, etc. need only slight mods, like a bit of narrowing the fuel tanks,(body side step ladder fit here)  removing a bulge on the frame along one of the trucks. (for a flat body fit).

I was only trying to look up the footprint for one of Walther's coaling towers,...and ran across this site and image as a result of 'images'

I have been using a wire mesh filter for some time on my airbrush. I use acrylic paints for my trains. Even though I try to clean the filter after each use it has gradually clogged up. I have soaked it in airbrush cleaner for acrylics but it is still difficult to get rid of the gummy residue. What is the best way to clean the filter or do I need to replace it?

I'm in the process of installing some operator comfort features to the layout like armrests and beverage holders. I found a neat holder online and a friend printed several for me.
