    Hmm... if the jaw is for clamping, I guess using a drill motor would be enough but won't have much in the way of crushing effectiveness though I guess that isn't what you are going for. The threaded...

    Thanks for all your thoughts folks! The problem with the Gimson linac is that either the retracted length is too much, or the stroke too small. So either the butt end of it sticks out of the back...

    Are you a bit lighter this time Bad Wolf? ;) As for soldering (again, Sorry!) If anyone needs to go outside, I'll have a gas iron with me that they can use.

    Ahh yeah, 200N is only about 20kg so it's more a lack of power that'll be stopping it. The ones I've had in those situations have been 75kg and above, and that's when things can start to get unhappy...

    As far as I'm aware, you're right about there not being a specific stopping mechanism Jamie. When I've tested Neophyte in the past with the locking bar in the actuator has simply stopped, which I...

    Unless I'm missing something, there's no stopping mechanism in the actuators apart from the limit switches at the end. So if the actuator is not at the end of its travel and power is still applied,...

    That is correct, 205mm for a 100mm stroke. However the actuator will stop itself if it is unable to move to it's maximum extension, so you wouldn't need to worry about making the full 305mm fit....

    Personally, I think the method you suggested would work as per the CAD diagram you posted You'd want a multi-stage spur gearbox to make it work rather than a planetary if horiztonal space is an issue.

    Unless I'm misunderstanding the drawing on the Gimson website, that actuator is mm long when retracted. That means 205 mm for a 100 mm stroke, or 305 when extended, which is still a bit on the long...

    I don’t know about everyone else but I think the most complicated thing to do is actually think of a name for your design. Then once you have thought of one, to find out that name already exists with...
