Some of the show and tell items. There were brought by Beevo. Object in the foreground is a welding stop, aluminum block with cup magnets to hold stuff in place during construction. 80# pull magnets, two of them....
Round object in the back is the displacer housing for the miser Sterling engine Beevo is building.
Green item is a mini tapping tool that uses ER11 collects to hold the taps.
