Linear Actuator remote location
(OP)
Hey all, I am trying to build a scotch yoke system with multiple sliders positioned along a single rocker arm. The issue that I am running into is finding a good way to elongate my electric solenoid shaft.
I can get a solenoid that will give me more than enough stroke length to rotate the cranks where I need them, but I would like to hook up multiple cranks to this system and have it span about a 1.5 foot length. Any suggestions on a reliable way to attach a longer shaft to the end of a linear solenoid would be greatly appreciated.
I have thought about adhesives, threading both components, and clamping the longer rod on, but I have no idea which will hold up to loads the best and take the least amount of effort.
Thanks

For a simple tubular solenoid, you don't need anything real fancy; low alloy steel, shaped like the OEM solenoid plunger, annealed and nickel plated, should be sufficient.

You haven't given enough detail to assess whether a solenoid actually is a good choice.
At some levels of mass, a number so far not in evidence, other alternatives exist, e.g. door lock motors.

@ itsmoked: I will be using an AC solenoid, but the duty cycle shouldn't be an issue. Thanks for the heads up on that though.
I also just looked into the car door lock actuators, and those seem like a pretty decent alternative. Any idea what sort of stroke length I can get out of a standard one? Also how well would they hold up to the load of an elongated shaft?

The door lock actuators are well adapted to running exactly one thing.
So use a bunch of them and forget the mechanical selector mechanism.
