The case is a large, hollow Bakelite shell, it’s fairly simple in design but it’s large, or rather it’s large enough to make casting a copy of it difficult for me to imagine.
Can anyone tell me:
1. Can this case be replicated in resin? 2. How difficult it’s likely to be if I’ve only ever created small casts before.
The case is about 16” diameter; 6” deep and 1/8th inch thick.
The back is simply thick cardboard so that’s easy to copy; the knobs are very easy to copy too and I’ve had great success with them.
My reason for wishing to replicate the case is mainly because I want to create a Bluetooth version of this radio, but I don’t want to mess with the fully working valve original as it’s a reasonably rare radio.
If I can create a decent resin copy of the case, I can modify it however I like and not worry if I damage the case or have to cut bits out of it while experimenting.
If anyone can talk me through how I might make a mould for resin casing this shell, I’d be very appreciative. My main sticking point is the fact that it’s a hollow, rounded shape that’s circular; I just can’t visualise how I can make a mould that will produce a hollow shell of his size, although the Bakelite original must have, I assume, been cast too...
I did try vacuum forming a copy but that did work at all well. Also the Bakelite, while sound and strong, is probably brittle so I don’t want to stres sit too much.
