Spark arrestor source?

Have you checked with P and D Hobby Shop?

Thanks...good idea.  I just fired off an email to P&D with a pic.  I see a couple of "stack, exhaust, EMD" in their on-line detail parts section under Precision Scale, but no spark arrestors.   I also sent an email to Precision Scale a week or so ago but haven't heard back from them yet.

When I wanted some like that a few years ago I couldn't find any - possibly not helped by a lack of pictures on sites such as P&D. Also being in the UK shipping cost from the US could have been very expensive for just a few details, so I scratchbuilt mine in exactly the same way - plastic strips and brass mesh!!

Even a lazy hack such as myself could scratchbuild a boatload of them in one week.

Plastruct or Evergreen Scale Models styrene and mesh from the Lipton Pyramid Tea Bags would work just fine.

Thanks everyone.  This will be a good kitchen table project.  I was hoping to get a few for dimensions, but should be able to figure them out with some reference pics.  

It might be hard to picture, but when I was a kid, I made some spark arrestors using wheels from a Hot Wheels car. I stuck a short piece of stiff wire in where the axle would go. I then set them in the stacks of my postwar switcher. They were about the right size and looked quite good. I still have them some place.

 

I don't have any real close-up pics of the spark arrestors I made, but you can see them on the roof of my Atlas FP7*, here...


*Atlas never made an FP7 ?? Correct; it's made from two F9's spliced together.... :-)

Hey gang- I had a bunch of the bee-hive arrestors cast a few years ago but am out. Sorry I don't have any to sell. Surprised someone at Shapeways hasn't done one in O scale yet? Might be worth contacting someone on that end as they are making quite a few interesting O scale parts.
