I'm building some 3D printed PRR E-44 shells and need some fine brass screening for some inlet areas. My supply is gone and my source no longer exists. Any ideas out there for a source and what mesh I should look for ? --- Thanks, Ken

I would look at Eduard. They are well-known for high-quality military model kits, and they also have a number of etched detail upgrade kits for 3rd party models. They are basically the Plano Model Products of military modeling. This square mesh has .4mm cell spacing, which is about 1.3" in HO scale: www.eduard.com/eduard/mesh-4x4-square-steel.html?cur=2&listtype=search&searchparam=meshThey also have different shapes like rectangular and hexagon; I would check out their website. Eduard is based in Europe, but I found this product on eBay too, so you can get it in the US. I'm assuming you are trying to make those grilles up near the roof on the long hood. 1.3" may be a bit oversize, but I think it will be difficult to get anything much finer than that, and you risk clogging them up once you primer and paint the model. |

The source is Shapeways. Designer is CMS workshops. They sell the basic body kit, two separate sides , a roof and a detail kit. If ypu order the parts get them in the clear ultra detail material not the tan plastic as it is very fragile don't ask me how I know. The parts require a Bachman E-33 drive and walkway. Also needed is a horn and pantographs. Builds into a pretty nice looking E-44. I will look into the Eduard screening thanks for the tip ! --- Ken

Six listings for one shell? Bruh.
Why are the sides and roof listed as separate products? Just mold them into the shell. This guy added like $30 to the price of the model just for doing that. I'm assuming the reasoning is to have all detail surfaces pointed upward to avoid any printing support artifacts, but the benefit is negligible since the details are so low-relief anyways. If they were big overhanging panels? Sure. But doors that protrude 1 scale inch? Basically price gouging at that point.
Even if there were defects on the vertical surfaces, some sanding and polishing is pretty easy to do here. The design of the shell seems really wasteful and inefficient.

“Weird, Shapeways' own search couldn't find it...”
That you could not find it using the Shapeways search function is not surprising. The Shapeways search function is useless. You either get nothing or many thousands of items few of which have anything to do with what you are looking for.

You either get nothing or many thousands of items few of which have anything to do with what you are looking for. DavidB The Shapeways search function is driven by the tags attached to the product. Below the description of every product, the tags are listed. In the case of this E33 shell, the tags are the options in the search tree (options like HO scale, the era, or the type of locomotive). When listing a product, Shapeways makes you choose these tags so the item ends up in the proper category. Designers can also make additional tags by typing phrases or words. The reason the E33 shell is hard to find is the fact that the creator didn't add good tags. The name of the product isn't even a tag, so 'E33 shell' brings up no results. I don't think creators understand the function of tags or how critical they are to being able to find a product on the site. Shapeways also searches using an 'or' command, so if you type in "HO Scale", it brings up items with the 'HO' tag OR the 'Scale' tag even if the product doesn't have both, which is why you get other scales like N scale or military model scales. It really should be using an 'and' function to narrow it down to listings that match every word in the search bar rather than only one. |

Forum users here are fairly search-impaired. You can read countless threads over the years that devolved into searching issues they had. Even back when it was Atlas running it.
And Mr. Trainiac is correct in how to use Shapeways search.

I agree. I was speaking in general terms. It's pretty prevalent here. Forum users here are fairly search-impaired.

Hopefully the clear resin is decent. The last thing I bought from Shapeways was the SW1001 and that shell cracked up on its own like it had zinc pest. |

/Not to hijack this post but does anyone know where to get screening material that is already shaped like what athearn and i think scale trains used on the tunnel motor intake grills? It was kinda like /\/\/\/\/\ mesh.

It was kinda like /\/\/\/\/\ mesh. Years ago, Overland sold what they called V shaped screening in a few different sizes. Good luck finding any though. If you find a current source, I'd be interested in some too. |

What about a corrugated sheet tool like this: www.greenstuffworld.com/en/texturing-tools/357-corrugator-tool-for-corrugated-metals.htmlThe corrugations look a bit coarser than you need, but the concept makes sense. I've also seen some that are press-based, where you sandwich a sheet between milled metal or acrylic blocks. If you find a mesh with the correct hole pattern, you might be able to build some kind of device to make the corrugations yourself. |
