Re: [CAD_CAM_EDM_DRO] surplus pneumatics ( was Re: Sources for beltsandpulleys

Chris,
thank you again.
I also was thinking of a pneumatic brake cylinders for a truck. As Dave
pointed
out , another way of doing is by increasing leverage. The problem is that
increased force implies stronger and heavier frame which I would like to
avoid
at this point, in case I have to ship it somewhere for a tune - up of
software.
Regards, Alex
