Re: syncing 2 16mm projectors

It all depends on your budget.

In the old days, selsyn motors were commonly used to sync multiple
projectors. These days, it might be simpler to use stepper motors
and a stepper motor controller card on a computer -- you'd need to
disconnect the internal motor and attach the steppers to the inching
shaft with timing belts. You have to be careful not to turn on the
lamps until the motors are running.

This isn't rocket science, but it's a fair amount of work -- perhaps
someone has an old rig available that is already set up.

If the projectors are next to each other and can be bolted down,
there are other ways of doing this, but it sounds like you need them
to be separately installed. Selsyns, steppers or servo motors are
the way to go.

Expect to spend some money on this, unless you are good at hardware
