    David,
    What is the mirror wax used for in that photo of the aft section being molded?
    Peace,
    Tom

    Typically I use the Buna wax as one-half of a two-part GRP part-release (wax-PVA) system when employing hard-shell type tools.

    In this particular case I'm casting RTV silicon rubber tools that feature porous foam blocks -- they reduce the volume of the flask to limit the amount of expensive tool making rubber. The wax is used to fill the surface of these rough surfaced displacing blocks in order to ease removal of the RTV tool once it's changed state from liquid to solid.


    As silicon rubber will not stick to anything but silicon rubber -- meaning I don't bother with a mold-release when casting a tool -- you still have to reduce the 'tooth' of anything you want to later part from the hardened rubber.

    Thank you for explaining that to me

    David, when you cast a metal shaft or rod in a piece, what do you do to the metal rod to keep it from sticking to the hardened resin?

    No part-release is required for mandrels/inserts used to produce a bore in cast resin parts.

    However a mandrel used in metal casting must first be coated with silicon grease to make it an easy task of removing the mandrel from the frozen part.

    Sometimes I'll used a preformed RTV silicon rubber mandrel, such as here:

    What I've presented so far in this thread (pictures with no text) is a teaser. By the end of the year I hope to have finished a proper construction article, chronicling the work from concept, masters, tools, parts, to completed model.

    However, any questions put forward here will be answered to the best of my ability (which is considerable!).

    Thank you, sir.

    Just passing on the things many in this game shared with me. We all are the sum of the things those who came before us shared. We either pass it on, or it will be lost. There are no secretes to this Craft, only fools who think there are secretes.

    Once robot (CAD, CNC, 3D, etc.) produced models become accepted by all, the chain of knowledge-pass-down will be broken. And another Craft will be lost to the world -- the only remaining reminders of hand produced models in the form of the yellowing pages of ancient model magazine articles.

    I've lived too long!
