    Remember reading an article in the old Tripod Graysubs site about David Jacques HMS Resolution with a rather unique ballast system employing bellows from a car steering wheel. It was mentioned that there was an article posted here. Does anybody have a copy they could possible share?

    David will be "chuffed" about your enquiry!

    The article was in a special issue of "In Depth" the AMS magazine in 1990.

    I've just uploaded this to our Facebook site where you can download it from the Files section.

    (Let me know if you have any problems.)

    David Jacques has just let me know the following (Magazine available in the Files section of our Facebook site or will be when I have uploaded it in the next few days. Still at 2002 at the moment!): (Later edit: NOW POSTED. It is very ingenious method of adding proportional control to piston tanks etc. )

    "The magazine with the proportion control Bellows article is Volume v1 No4 1988 . Regards David."
