Hi one and all. It's good to be back. I have been quite busy changing jobs, moving home and what not and, most importantly, devoting a LOT of time and work to coming up with a new "line" of ribbon mics (which I machine in my garage-cum-workshop, heavily laden with industrial tools I got to that effect). Anyway, as I want to come up with the reasonably most efficient, best sounding, niftiest-looking mic I can concoct (don't we all?), I am currently in the process of putting together a test rig featuring a number of motors and a number of trafos, both switchable, to assess what is the best way forward.
The magnets I am using are neos I've had made, measuring 50 mm x 10 mm x 3 mm, with the polarity running across the 10 mm side. I fugured this shape and thickness should make them pretty good for ribbon use.
One of the motors will be a stamped chassis to which will attach the magnets et al., another is a similar arrangement, only that fitted within a mild steel (EN1A silver steel) frame, another will be like the previous one, only that the frame will be iron proper and another one will be the magnets attached to two square (6 mm sq. thick) mild steel rods as above, but without closing an MRC.
Now, here's the question: I will have access to an electric kiln that can bake anything up to 1300 deg C, which I will be using to harden tools and punches and dies. Can I use this to increase the magnetic flux of the steel or iron frame? I have read in previous postings about how it'd be to bake motors at 1200 deg C in a hydrogen fired oven. This one won't be hydrogen fired but, will that make any difference?
As always, any feedback, ideas and points of view most welcome.
