Ive made my own scales too but not with epoxy!you need laminating fibre glass resin,again very easy to make.
Thanks for the info. I'll have to give it a go now just for interests sake, although it will have to be with hand tools as its not worth paying a stack on proper tools for this one job; if the Mrs thinks I'm capable of anything useful bang goes my retirement!!! I'm still looking into the group buy as there are so many people who would like them (including me).
As for the Fibre Glass Resin, yes you can use it, it's just most of the searches I have conducted use the term 'Epoxy'. In fact the resin used for production of fibre glass would appear to be a 2-part polyester, vinyl or epoxy substance, so it's 6 and 2 x 3's. The main reason for not using the Araldite type of epoxy seems to be the price, preferring instead to use the Fibre Glass Epoxy-resin/polyester/vinyl substance as its relatively cheap.
Either or, they all seem like nasty stuff when you're sanding etc, so another expense is PPE!
