I'm looking to buy a mouth diaphragm building jig. This is going to be a hobby only, so I'm not necessarily looking for something top of the line. Feel free to PM me or just reply here with what you might have, or point me in the right direction of something to get started on.
Thanks in advance
Check out Ricky joe bishop on Facebook. Makes a small printed jig that is surprisingly good for its price point of around 50$
