Hi Edo ,
Panel lines are a challenge for as all but there are ways around them . It really depends on the type of scriber . The squadron one I use cuts a " V" shape channel . The hard you press the deeper it goes making the line wider so the key is to rather make light passes until the width matches the others . Took me a while to learn this
I have PE scriber but I really don't care for them , can't control the width of line needed . The old tried and test method is a sewing needle in a pin vise . Or the back side of the tip in a #11 blade . For my straight edge I scriber along a metal ruler or will use dymo tape . If I make a mistake I will fill that line with stretched spuce form the kit using Tamiya quick setting . It melts the plastic faster . This of course is for plastic kits . On resin kits If I need to redo that line I fill with super glue , sand/polish and start over .
On plastic kits once the line is made I lightly sand it to rid of build up and then run tamiya thin in the line and this will smooth it out .
Rick ,
That is a nice prop and I never seen one cast that way and ..yeah how does one remove the bloke with damaging the prop it's self .
I would use the back side of a # 11 blade on the underside of the prop and score it free , better control then using a saw blade . Resin scores quicker then plastic so care still is needed and only slight pressure . This might be time consuming but will give you less clean up .
Thanks guys
