   I've been toying with the notion of doing something like this to the
craptastic sliding feets  (honestly, it's as they were made out of  Dupont
Teflon) of my Coleman grill stove, which must have been invented by people
who neither camp nor cook.

   How about corner jacks for Westies like trailers have?
