[PSUBS-MAILIST] home made actuator

[Alan via Personal_Submersibles]

Hank,
my first thought was satellite dish actuator.
This one is claiming 500lb capacity.

But you wouldn't need that with horizontal travel. Any idea what force it
takes to pull / push it? I assume it is external.
Just wondering why you need 400lb!  
Cheers Alan

I am planning to either add a oil filled trolling motor to a trailer jack or mount the trolling motor to a satellite dish actuator.  I have not dismantled the satellite dish actuator yet to see if it can handle the job.  I think it can but I will see.
