I have an Ekco AC76 radio with an unusual Bakelite case: it’s You can see a photo of one here, if your interested: www.worthpoint.com/worthopedia/ekco-ac-76-bakelite-radio-1935-168542821The 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.

1. Can this case be replicated in resin? Yes, it can be replicated 2. How difficult it’s likely to be if I’ve only ever created small casts before.
Just think of it as a bigger, small cast....the same principles still apply, just more rubber-n-resin involved.....don't let the larger size intimidate you.

Also you'll need to do at least a two piece mold.
