    Help Needed

    All,

    I've been trying to cast some snakeskin. The main issue is that using CA or Elmers turns the skin dark. See photos. The other issue is air bubbles. Even thou I'm pressure potting them at 50psi.

    Any ideas?20200531_114801.jpg20200531_114746.jpg20200531_114730.jpg

    Have you tried double sided sticky tape?

    Don't you use pressure to shrink the bubbles?

    Some probs come from loose scales to be sure double check the skins.

    Are you sure that the discolouration comes from the glue and not the resin?

    It's deffo the glue. The moment I put CA on to the skin (either front of back side) it turns dark. When using elmers on the backside it still turns dark.

    I did think about using wallpaper paste or as someone else suggested double sided tape.

    It's driving me mad.

    That implies then, that it's due to absorption. You could try sizing the back first, but actually I think that Paul has already solved the problem - you need to use double sided tape instead of glue. Next time you cast anything, put a wee offcut of the snakeskin in there somewhere where it won't matter to the blank, to see if the resin affects it without any glue.
