A question to those that build their own moulds.
Hi all:

A question has come up from my building about how the lines in the various moulds are produced. How do you make the indented lines that represent the various panels or joins in the bodies? Do you carve them, cut them, or build up over tape with sanding primer? Thanks.

Thanks for the idea, Tony. But I should really be doing a hand slap to the forehead because of forgetting about Darrell, lol. Thanks, Emile.

I use 3M chartpak tape and high fill primer... Then highlight over with a scribe tool (micro mark sells a great one).Home of the "Sea Cobra".....

Hi Jim:

I have heard of that method and have seen that it produces some very nice lines, indeed. The method requires spaying and in my condo, there is no place I have access to, except the balcony, for such a job. It is now a deep freeze so outdoor work is out for now. I might use that method for creating a raised panel edge once the weather breaks as I do have some 1mm tape. Thank you for the suggestion.

I did get a couple of more suggestions via the phone and they are all good and "easy to do" methods. Using a #11 blade, but the wide part rather than the cutting edge, makes for a very simple cutter. I can create a hooked cutting edge with the use of a Dremel grinding disk. Using files to soften the edge will help keep the line from deteriorating by being nicked but items catching on the sharp edges of the indentation. I remembered that I have a complete set of checkering files which will define the lines without cutting much lower than the upper layer of resin or just into the gel coat, whatever is left where the lines will go. Thanks to all.

Hey Don, go to micromark and get their scribing tool. It really works well and makes kind of a "V" groove ...Home of the "Sea Cobra".....

Hey, there's some really nice hand tools available from that company. I will keep an eye on the current progress and if my work looks a bit dicey, I'll get a few tools to make the shipping costs worthwhile. Thanks.
