WildeSau75 Posted January 10, 2019 Share Posted January 10, 2019 Hi guys, I am building the 1/72 Academy Harvard IIb and used some Mr. Surfacer to close some seams which I then sanded. Unfortunately I sanded some panel lines away and now look for the best way to rebuild them. Any tips? Regards, Michael Link to comment Share on other sites More sharing options...
Steve Noble Posted January 10, 2019 Share Posted January 10, 2019 I assume they must be the raised kind if you've sanded them off? When I used to build aircraft I simply used to apply some stretched sprue which I made the same diameter of the original line then glue it into place with liquid cement used sparingly..

dnl42 Posted January 10, 2019 Share Posted January 10, 2019 (edited) Are these engraved panel lines? If so, various plastic scribers are available, or, you could just use a knife/scalpel blade or a pin in a pin vise. The engraver I use for straight or slightly curved lines has a hook tip, so it actually removes a thin strand of plastic from the surface to create a "trench"; repeated applications will deepen it. I do also a pin in a pin vise when I'm using an engraving template because it's easier to scribe curved lines, like a round panel or such. If they're raised lines, you can use a knife blade to score the surface. That scoring action will displace plastic to the side to form a ridge.

HTH -- dnl Thanks a lot - yes, I mean engraved panel lines. I tried with a knife but always slipped off on uneven areas. Which tool would you recommend for rather thin lines? Not sure I understand what a pin in a pin vise is.... Cheers, Michael Link to comment Share on other sites More sharing options...

Thanks mate - the are engraved. When sanding off the Mr. Surfacer part of them came off. dnl42's reply should do it I guess. Again, thanks.

dnl42 Posted January 10, 2019 Share Posted January 10, 2019 You need some sort of template or edge to guide the scriber. When using a metal scribing template, like this one, I tape the template to the model to prevent slipping. You could use any thin metal strip for this purpose if you're doing a straight line. In the US, we can get "Dymo" tape for making "embossed" labels. This tape will adhere quite nicely to the model and provides a good edge for this type of work.

Cheers, Michael Michael, This is one form of pin vice In some cases to get a straight line you need a guide to scribe against, either a flexible ruler or run thick tape (like electrical) along the line you need to rescribe. You could also check youtube for rescibing technique videos. 1 Link to comment Share on other sites More sharing options...
dnl42 Posted January 10, 2019 Share Posted January 10, 2019 As for tools, you could use these tools from RB Productions. He's got some great tools on his site. A pin in a pin vise is a pin of some sort chucked in a small hand-held drill handle, like this Link to comment Share on other sites More sharing options...
roginoz Posted January 10, 2019 Share Posted January 10, 2019 The Dymo tape suggestion in post 6 above is the method I always use, but stick the tape onto a similar length of Tamiya tape [or similar] as the Dymo tape, I have found, often leaves a more sticky residue than does the Tamiya tape. This provides a firm edge against which to scribe. Placed carefully against the panel line, and using a scriber as described above, a clean panel line is [generally] the result. Good luck !

If it's not working, I try to get hold of the Dymo tape Link to comment Share on other sites More sharing options...
WildeSau75 Posted January 10, 2019 Author Share Posted January 10, 2019 I am again and again positively surprised how quick one gets very useful replies from friendly and helpful modelers all over the world. Indeed a great place for modelers BM is! Thanks again to all of you - hope to be able to post some picks of my build with perfect panel lines in the near future.

Steve Noble Posted January 10, 2019 Share Posted January 10, 2019 Ah, so for engraved lines I always use my Olfa P cutter. It actually removes a very thin sliver of plastic rather than just pushing the plastic aside like a needle in a pin vice does. Most useful tool for redoing panel lines I can think of..

bhouse Posted January 10, 2019 Share Posted January 10, 2019 For curved panel lines, a flexible curve (more properly called a lesbian curve) is a very useful guide. Link to comment Share on other sites More sharing options...

Ha - a lesbian curve - there where other things coming to my mind ;-). This looks indeed useful. Thanks mate. Link to comment Share on other sites More sharing options...
