Sparzanza Posted March 9, 2017 Share Posted March 9, 2017 I recently resumed work on my 1/48th scale Tamiya Dornier Do 335 "Pfeil", and its wheel wells are absolutely littered with these nasty ejector pin marks in the worst of places, making them extremely hard to remove. At the moment I'm working them by gluing a tiny piece of sandpaper onto a toothpick and "sanding" them away, but it's time consuming to say the least. How do everybody else go about getting rid of these? The marks I'm talking about are probably called something else if they're protruding, but my vocabulary fails me at this moment. I tried scraping them off with an Xacto blade, but can never seem to get rid of the scratches afterwards... so sanding it is. Link to comment Share on other sites More sharing options...
Martinnfb Posted March 9, 2017 Share Posted March 9, 2017 I am using rotary tool with round bit and with gentle circular movement blending the circles into the surrounding area, then with acetone or lacquer thiner smothering the bumps to even layer, literally melting it into submission. But that's just me Link to comment Share on other sites More sharing options...
LSP_K2 Posted March 9, 2017 Share Posted March 9, 2017 Raised or recessed, they're ejector pin marks all the same. Getting rid of them can be a real pain. If it's too awkward, I just grind them away, then cover the area with a piece of .005 or .010 sheet plastic, if doable.

Sparzanza Posted March 9, 2017 Author Share Posted March 9, 2017 The problem is that there's a lot of detail surrounding them, which is why I put all this effort into removing them gently. LSP_K2 1 Link to comment Share on other sites More sharing options...
LSP_Kevin Posted March 9, 2017 Share Posted March 9, 2017 See if you can get yourself a set of micro-chisels, Sparz. The Trumpeter ones are quite common, and pretty cheap, too. And, even better, they're a decent quality tool. I've found them invaluable for precision removal of material. They come with tips of different shapes and sizes, but generally look something like this: Even if you don't use them on this project, you'll definitely find them useful in the future.

dodgem37 Posted March 9, 2017 Share Posted March 9, 2017 If there isn't enough room to use a chisel, you can adhere sandpaper to the end of a wood dowel and use that. Sincerely, Mark Sparzanza 1 Link to comment Share on other sites More sharing options...

TonyT Posted March 13, 2017 Share Posted March 13, 2017 Might sounds silly, but can you not use a hole punch on a thin sheet of plastic card and then stick the punched out circles in them and sand it flat. Sparzanza 1 Link to comment Share on other sites More sharing options...

Yeah, if I had a hole punch thing and a thin sheet of plastic card, that could work for the ones that are hollow. However, these are protruding, mostly. Also tiny.

TonyT Posted March 15, 2017 Share Posted March 15, 2017 Could you in that case not trim the sheet around the hole you have punched to fit over the protrusion and in the space you have? Link to comment Share on other sites More sharing options...
Sparzanza Posted March 15, 2017 Author Share Posted March 15, 2017 Could you in that case not trim the sheet around the hole you have punched to fit over the protrusion and in the space you have? Hmm no, too much detail around it. Link to comment Share on other sites More sharing options...
CANicoll Posted March 17, 2017 Share Posted March 17, 2017 If you can't go for the chisel's try the point of a #11 blade (X-Acto or whatever). Some where along the way I picked up some chisel-shaped razor blades that I use as a chisel for exactly this kind of thing. It is about 3mm wide so might fit. But they do tend to bend so a bit harder to control and now that I know there are chisels that small out there, I'll probably go for the set - they look very handy and easier to use.
