a) metrication in France (the one we are talking about) happened during the revolution, no monarchy left! b) It was defined by the French at the time as a ten millionth of the distance twix the equator and north pole passing through Paris on a line of latitude. To top it all the inch was defined as exactly 25.4mm in 1959, other common units have been referenced to the metric system to, so we all use metric, sometimes without knowing. Back on topic, if using kitchen worktop support it quite well, an unsupported span of a metre (yard, couple of cubits) or so will sag after a while. Great for kitchens where cabinets sit under it. |

Re: Light work bench.
Kitchen (chipboard) worktops are usually either the thick type or the not so thick type, if using the thicker type for heavy work then I would recommend 600mm maximum unsupported span, another thing worth mentioning is if it's going in a damp building/shed or there's a chance of any moisture sloshing around then seal any exposed edges against moisture using an edging strip glued with impact adhesive.
As an alternative run a bead of clear silicone rubber along the exposed edge(s) and rub it in with a cloth, let it go off a bit then rub another layer in, that's the way I did all the edges of worktop cutouts and the back exposed edges of worktops when installing them and fitting drop in sinks etc. Lawrence. |

Re: Light work bench.
TBH if I was in an environment where damp-ingress to the ends of MDF shelves/worktops was likely to be a significant issue I'd be vastly more worried about the overall health of any electronic equipment stored there!

Re: Light work bench.
The 2nd picture, bench loaded up!
You have a collection, that many comm receiver collectors in the states, long for! Ar88, HRO etc. I recognize several in your collection, except for a few. Is the receiver to the left of the BC348, a Hallicrafters? Is the valve tester a TV7? Please post back with the complete rundown of your receivers. BTW, great job on the bench! Dave. |

Re: Light work bench.
TWO AR88s AND a B40 on the same bench?
Light workbench? To make the bench in my garage, I went round the timber merchants and picked up a couple of cosmetically damaged fire doors. Cheep, strong and good looking. They went on a steel frame made from 30mm sq box section. I bounce engines on this bench Ooh, an RA117. David

Re: Light work bench.
Just the one AR88d David, the other AR88 ref is the loudspeaker for it, a good chunk of all that stuff was previously on a kitchen table which I made years ago which was also duty heavy.

Re: Light work bench.
The grand plan was to link the two benches together with another one but the plan changed
I built the building they were in as well specifically as a workshop, the cats have it now along with a pile of my DIY stuff and other general dross, but that's another story. Lawrence. |

Re: Light work bench.
Thanks for posting all the pictures of the real great collection!
It seems to be an unwritten law that vintage electronics collectors, have to have cats, one or more! I have three, that oldest being 19YO. |

Re: Light work bench.
my kitchen worktop bench is a little over 2m. Initially supported at each end, when I tried the 'sit-on' test, it gave a little in the middle so I added a mid-way 45deg brace, from front edge to skirting board.

Re: Light work bench.
The metric system is designed for scientific measure. Makes calculation in decimals far easier. Imperial units are ancient and based on things on the scale of the human body, so are easy to visualise - low tech - a tangible system for daily use. Horses for courses.
