Im hunting for some sawmill blades for my mill project but really having trouble finding something hat doesn't have a 6mm hold in the center (dremil blades ect) Anyone got any ideas? Im looking for 42" or larger scale blades.

You can see a video of my layout(before expansion) here, and photos and a track plan here and here.

I recently purchased a Paasche VL airbrush as an replacement for my Paasche “H” airbrush. The new airbrush came with three needles and tips (#1, 3, and 5). My question is for general airbrushing (locomotive shells, buildings), which size tip should I us to obtain best results?

Dear C&O Greenbrier Branch fans,

Ok, here's some for the brains trust:
- On the Greenbrier branch (Ronceverte to Durbin, via Cass), was Brill railcar 9055 _typically_ shuttled back/forth (and therefore did some running "tail first"),

OR

Was 9055 _strictly_ turned at each end of its return-runs (IE 9055 _always_ ran "head/cab first")?

- Was 9055 ever (however commonly or otherwise) run with a sister Brill coupled "tail to tail"? (IE run with "a cab at either end", thus avoiding any need to be turned?)
