Welcome to Librarium Online!
Building up my first TK army, and I have to say, I have no idea how to clean mould lines off of plastic skellies. A lot of the lines are easy to clean with a light scrape from a hobby knife, but the mould lines they go over things like ribcages and the spines if horses have me stumped.
Is there a trick here that I can use?
I've never played WHFB, but Necrons present all manner of annoying mould lines in weird places.
My advice: Get a needle file set. Gale Force Nine (I think) sells a five-piece set of diamond files that are thinner than a pencil (hence the name, "needle files"). They're not that expensive, and well worth the investment. You'll find the files come in various shapes, to help get those hard-to-reach places. They work especially well on metal models, I find.
I have a half round and a round needle file, but I find they clog very quickly on plastics, but thanks for the advice.
Honestly, I am only looking at a tabletop level of painting anyhow. I was sort of hoping that ribcages and the like were one of those places that people would overlook a little trouble with mould lines (not to mention how infrequently the two halves of the mould line up properly on something like a ribcage).
You can remove mold lines on plastic just about anywhere with an x-acto knife blade. As you did in the flat areas - gently scrape over the area where the mold lines are. It takes quite a bit more effort but if you do it gently you should eventually get rid of the mold lines.
The key is persistence and gentle handling. Push too hard and you risk digging into the details...
I guess I just need to keep at it then. The raised areas are okay, it's the recesses that are so tricky to clean without, as you mention, damaging the details. Not that there is much detail on a ribcage, but there sure are on vertebrae...
You can gently scrape from both directions and with care you should be able to scrape away the mold lines even in areas such as the rib cages... It is a pain but rewarding once you get it done...
I can't tell you how much better a figure looks with the mold lines clean, vs. ones where a little is still showing...
The cost is a tremendous amount of time though...
Time is a bit precious around my place these days. I'm falling into the 'well those ones online look so much better' trap to a degree here.
Anyhow, thanks for the advice. Sounds like I'm doing it right, I just need to do it carefully and for a longer period of time
Never under-estimate a sharp blade. The sharper the blade - the better the scrape. If you blade is too dull it may not work as good.
