Mould improvements

I’ve been getting some interesting cast out of the first mould I made for the waggle pods, but a lot of out-right failures too. It’s been feeling like I’ve been fighting the mould most of the time.

Time to make a new mould.

I managed to get a decent wax cast from the first mould which I dressed to make into a pattern for the second:

I decided to include a pouring hole in the design for this mould – more to assist with cooling and extraction than for the pouring process itself. Also a few extra details like handles, because I’d been struggling to part the two halves of the last mould.

Wow! This mould works a lot better! The first three casts have all come out successfully, so I now have enough to experiment with to try and get a solution for inserting and fixing the electronics…
