I've never done rolling stock painting or weathering before and I was thinking of starting with some HO freight cars using acrylic paints in washes and chalks or powders.  What types of brushes (size and type) do you recommend using?

Is there anyone who can give me some photos of street running and some info on how you did it I would like to write an article to send in to MRH if possble.

Thanks for the help trainmaster247

As many of you know, I've been experimenting with 3D printing through Shapeways, trying to learn what is possible and what is practical.  While I've tried (and mostly succeeded with) a variety of models and parts of models, I am thinking that one of the best applications is the ability to create inexpensive detail parts, especially in HO scale.  Not only can I create parts for less than the cost of the same part on the shelf, but I can create custom versions with relative ease.  Take this, for example:

FastCap has a new tape measure that makes squaring up benchwork and fitting braces for shelf brackets a snap! It's called a SquareOne tape... and it automatically calculates the distance of the hypotenuse of a right triangle. So... it you measure out from a corner of your benchwork, say 17", make a mark, then measure out the other direction, mark it, and lay the tape between the marks... you read the other edge of the tape and if it shows 17", your corner is square!
