Reader Tip: An easy way to paint a gravel-textured roof

A model of a concrete building features a flat roof with a painted gravel texture.

I have a tip that I think other modelers might like: a fast and easy way to make a terrific roof covering. The gravel roof in the accompanying photo was painted with Rustoleum American Accents Stone textured finish. It went on in one coat and looks even better in person than in the photo. This […]

Ask MR: How do I build tray benchwork?

Steven Otte applies glue to a board as he assembles benchwork on the workshop floor

Q: I have a couple of questions about the benchwork construction of your Spartanburg Subdivision. How large did you cut the plywood sheet? Did you attach the 1x4s to the top of the plywood sheet, or at the sides? Where did the trim pieces go? How large was the sheet of foam you put in […]

A “truck tuner” – a double-ended reamer sized for the job – is used to clean and reshape the sockets in an HO scale truck sideframe assembly

Q: The axles stick in the journal boxes of some of my rolling stock. I tried scraping them out and lubricating them. Any help would be appreciated. – Christopher Kramer, Chicago A: Depending on what tool you’re using, scraping them out might be making the bearing surfaces rougher, worsening your problem. And lubricating axle bearing […]

Reader Tip: Make a simple, precise applicator tool

Three sewing needles with their eyes snipped across, inserted in dowel handles

Recent scratchbuilding efforts prompted me to come up with a simple glue applicator that would put a small amount of adhesive precisely where I wanted it. There are many commercial products to do this, but none were exactly what I needed. I took a sewing needle, measured its diameter, and drilled a slightly smaller hole […]

Ask MR: Should wood running boards be painted?

The roofs of several freight cars are seen in a black-and-white photo of a rail yard

Q: My N scale layout is set in 1933. Several years ago, someone whose railroading knowledge I respect told me that running boards on early freight cars weren’t painted since they would be dangerously slippery when wet. However, all the models I see sold now have the running boards painted the same color as the […]
