Im the pattern maker and foundryman. As a metal worker making my own furnace and tools was easy. Just had to buy the the rest such as sand,binder,clay,parting dust,flux..etc. im all set up. Im in a tought spot health wise so im left with no choice but to learnthe trade. Ill be 38 tomorrow,i want to have a steady income again when i reach 40. Im familiar with match plates and have 4 pattetns made that way waiting to be casted. That part is easy,where im having trouble is jointing the wood and making it durable after carving. I have my table saw set with jigs for milling and block joints.

that is a pretty ambitious project.
like on your other post with PatternGuy, you need to have two matching plugs
if you are going to cast it hollow in metal (probably aluminum?).
lots and lots of carving and sculpting to have the two correct matching pieces.
I am very familiar with the process and you have quite a bit of work to do to both pieces
to have a workable product.
how thick is your mahogany ??? you can use countersunk screws and epoxy to assemble the boxes.
just try to put the screws where you will not be carving, fill the countersunk holes with Bondo.
any 5 or 30 minute epoxy will work for your project.
[also, it would be wise to check with the foundry that will do your casting to see what percentage
of shrinkage they estimate in your casting and make your adjustments accordingly].
