Firing pin tool and ejector tool?

[TrxR]

Ive got a Borden BRM action and was wondering if anyone here has ever made their own firing pin disassembly tool? It simply looks like a fixture to thread the pin assembly in and a bolt with a hole drilled in it to accommodate the firing pin? How deep and largevshould that hole be?

Also anyone make anything for removing the ejector?

Thanks
