I'm looking for some help with a 180 degree pneumatic hammer design
Would you say this is the best/usual method to achieve what I am planning:
This just uses a crank to convert the linear motion to rotational. I've read in a few posts and on other sources that a rack an pinion system can be used with pneumatic linear actuators to create hammers/axes, but I can't visualise how the pneumatic ram connects to the rack to push/pull it.

I am considering a hammer for my middleweight design, Creep, ideally being able to invert and strike in front and behind the robot (think of a pick axe head). The bot design thread is here: https://www.fightingrobots.co.uk/thr...266#post477266

Any help would be greatly appreciated!
