What's the best way to replace raised panel lines? Is it best to use them as a guide for rescribing, then remove them after? Or is it better to remove them and then rescribe?

My problem is that I find it difficult to keep a straight line when scribing - the tool seems to keep sliding about on the plastic whenever I've tried it, regardless of whether or not I use tape as a guide.

I'm worried that the first method would results in panel lines that are offset slightly from where they should be and therefore look weird...

Personally I sand the original panel lines off first. You quite often can still see a line to use as a guide once they have been removed. I then use some Dyno? tape for the edge or a thin metal template to guide the scriber along. Trick is to do several light passes and not try to create the panel line in one go. This will reduce the slipping of the tool.

Hope this helps,

Nige

Thanks Nige, I'll give that a go. I was perhaps being too heavy-handed in the past.

I've never tried scribing panel lines exactly, but when I was trying to scrape out the vacuformed diorama pieces on a miniart diorama kit, I noticed that unless I had my knife completely perpendicular to the plastic it would go off on it's own even though I had a clear guide along which to scrape.

Will Pattison just put a really good video on scribing. He also mentions going at the first pass quite easy.
Might give you some more ideas.

I recently re-scribed the raised lines on an old AMT Tempest kit.
And I learned after painting that I made them too deep and wide in most cases.
Some people hate scribing, but I found it relaxing.

I sanded all the lines off first, but next time I might try leaving them.
I don't imagine that will work all the time, like when the raised lines meet or cross.

Thanks for the link to the video. I was just thinking about this issue earlier, as I tried rescribing some lines and it was a disaster! I went easy and it slid around, despite using the existing raised lines as a guide. I tried with a bit more pressure and it slid again, only with a deeper line.

What tool are you using? I bought the UMM Scriber.

The hook end is really nice because you can pull it toward you, and it gouges out a small curly-Q of plastic as you pull.
I have A LOT more control pulling than pushing.

I'm using the Tamiya scriber, it's probably much the same thing.

Probably, and Tamiya usually makes great tools.

Make sure your blade is straight up-and-down. If it is cocked left or right, it will want to travel the other way.
Try keeping your wrist stiff and imagine a string tied to your elbow drawing your arm backwards.
That will give you more control too.

In the old days.... we use to stretch some sprue! Then cut to the appropriate size and length; tack one of the ends and line it up and use thin cement to hold in place. It used mostly on small areas that were damaged by sanding... light sanding to match.

Good luck with the scribing! sounds challenging.
