Hi Frosty,
I will definitely try ganging up the sinkers to up my productivity since this sinker in particular is a high commodity among anglers in SA and they are quite expensive as well. So naturally I will eventually try to sell them to local fishing shops.
The flashing on the sinker problem started out when my electricity company decided that my printer are not allowed to finish printing. ie. the black spots on the printed mould are actually severed pawn heads from an old chess set I had sitting around. These heads are almost the same as what was needed but this mould still needs some work t ensure a flat contact between the two halves. Meanwhile I printed new hemispheres on the correct size and glued them on. I will try them like this as soon as my melting furnace are complete.(ridgidizer and drainage hole still needed)
I will design a new mould and post it for comment. Thank you for all the advice.
Regards
Kozzy,
If I must say, I`m quite chaffed with the flatness of the adjoining surfaces but I will definitely look into making the alignment pins detachable in order to get the surfaces flattened.
If I can ask, I would like to start using sand cores. Any advice?
