Re: Linear Actuator question

Chuck

It doesn't appear that linear actuators are part of their product
line. I'd assume that it's a solenoid.

If I'm correct you'd have to make some provision for locking the
router in both the up and down position as looking at their website,
many of their products have less than a 100% duty cycle. You'd also
not be able to control the plunge rate, and would have to take care
to accurately position your bits within the chuck.

Alternatevly, you may be able to implement a system to ratchet the
router up or down using the solinoid.

They do produce some pretty powerfull devices though. Some capable of
exerting forces in excess of 100 lb.
