advanced scribing help ?

[steveo3002]

ive had to heavily modify a part with car body filler , now when i try to scribe into it i no longer get a crisp edge because chunks on the very edge

any ideas how to tidy it up ? a rounded edge would be acceptable

or roar out the filler and use something else?

Can't quite envisage the problem but how about using a different product like Milliput?

I had exactly the problem on my Spitfire rebuild. I gave up and drew the panel lines on after painting.

With my Bf109 model, I had no choice but to re-scribe over a large area of hard filler. The only way I found of doing this without crumbling was to use a "Bare Metal Foil" scribing tool, guided by Dymo tape, and using very, very light strokes until the right depth was reached. The guide is just as important as the scribing technique/tool, becasue filler seems to draw the tool away from any given guide.



I was using Milliput BTW. Re-riveting the filler was no problem either provided light pressure was used.

I've never tried it but I know some people use super glue for filling for this reason - apparently no crumbling.

I prefer to use the back of a modelling knife blade to scribe with. The cut is done lightly and with the blade vertical to the scribed surface, marking away from the knife blade cutting edge.

Make sure the scribing is done along a firmly fixed line guide, a thin steel rule is good if there's room to get it on and hopefully tape at least one end down to give you a true guide line.

With practise (50+ years for me) you can get a very precise scribed mark.

Car filler should be OK to get an edge on, probably much like the effect of using Milliput I'd have thought.

thanks all

its not helping that the shape is a small curve that also on a rounded surface lol

[perdu]

A picture might help

If it is something personal I won't tell anyone

I can keep a secret

But often have ideas when presented with a specific problem, like many in here.

[steveo3002]

okay..im not near the model at the moment

heres a pic of the real car , see the squareish hole in the center , thats been moved and filled , needs to have a line scribed to look like the 2nd pic

[perdu]

Gotcha :yesyes:

if you have the right sized hole to hand why not cut it out of plasticard or even stiff cardboard, locate it where you need it with tape and scribe around within the shape you need?

For a job like that I would probably risk using a round section scriber to allow the rotating motion that will let you go smoothly round the corners. Maybe the spike of a drawing set compass, gently (always scribe gently to remain in control) until deep enough for the look you are after.

As the holes would have a definite 'curved in' look I might even chamfer the finished scribes with a sharp pointed tip of a number 1 Swann Morton blade to give it rounded depth.

Any help to you?

Hope so, I see what you are after, will be nice when done too.

I don't think he wants to scribe the hole outline - he's filled it up. It's the lines he wants to scribe over the filled hole to blend it to the rest of the panel.

At least that's how I read it.

[steveo3002]

the "handle" part was in the wrong place ...i hacked it out crudley and moved it along to where it looked right, glued it in place then made the surface all flush with body filler

so i have a smooth filler door panel that i need to scribe that square shape with the rounded corners ..edit heres a pic

It's too easy to misdescribe on t'internet when you are a bear of little brain like meself

I mean that as he has the shape he can rescribe it where he wants it by making a template of the hole, sticking it over the filled section and the good section, then scribing inside the template to make the new "cut out" section

I could have done it whilst telling you what I mean

Not rocket science just a small detailing issue

so;

Cut out shape

stick the piece of wotever you cut the shape out of (not the shape you cut out, that's for the bin) on where you need to rescribe, work around the edges of the hole to rescribe what you need. Then remove blanking panel and finish redetailing the interior "leather and plastic handle parts" with gentle work with your modelling knife

looks like quite a fun job, nice motor mate

I think I misunderstood it all. Ah well.

[steveo3002]

heres what i was struggling with

hacked this handle out and moved it





heres the result after rescribing the outline, not 100% pleased with it close up but its okay



this area was dead smooth yet the real car has switches and a vent along there
, so scribed some detail in , again not thrilled but better than nowt

[perdu]

Looks fine to me.

I bet it looks better in "real life" rather than as magnified imagery on the 'pooter too.

I think you have achieved something good there.

[steveo3002]

well yeah and the fact you wont see it when the car is assembled

the switchgear will be black once painted , so that will tidy it

If it's not clearly in view, did you consider leaving it solid and using a decal to represent the switches?

[steveo3002]

nah im happy with the scribbing really , if that had failed i would just have painted a black shape in its place

i dont have any decal making skills

[steveo3002]

did that with a scriber made by the bare metal foil company..theyre pretty nice

no havent tried a soldering iron
