Where's the chassis



Squire..

So far this is all mental gymnastics.

Why not do a prototype to prove and
debug the design, run it for several weeks to work out glitches, and
do one or two more test prototypes to finalize the design? This
will give you some idea on labor and material costs, and how much
time is needed to acquire parts... assemble... align and test.. etc.

I think at that point you'd have a better feel for what you are proposing.
One thing to think about: why not also offer a kit version? If you do
a magazine construction article, say in Electric Radio, that would
give you a "free" ad for the kit of materials, and some exposure.
