Having got around after 2 years, to restacking the hifi, I needed a
wheeled platfom to stand it on. I went into my stock of castors and
found some nice 8mm threaded castors which seemed ideal. After buying
some 8mm threaded mounting plates from Toolstation, I attempted to mount
these and discovered that my 8mm castors were in fact 5/16 whitorth.
Fortunately in my tool collection I had some Whitworth taps and dies, so
i was able to retap the 8mm mounts to 5/16 Whitworth. Some where over
the years i have lost my thread gauge plate which would have been useful.

Yes the case of an old steel rule was just the right size to stop a cabinet
wobbling in my old garage.

I regularly use some tools that retirees gave my dad, having used them
for donkeys' years, when he started his apprenticeship in 1936.

I still use whitworth stuff. Here's why

I think the only thing I've needed a 1/4W spanner for is to remove the
jaws from my ancient vice, luckily my neighbour has a set.

I needed a 7/64 allen key the other day but all mine are metric (2.5mm
too small, 3mm too large) turns out a T15 torx bit is a pretty good fit.

That's one benefit of being old. I started out with the then current tools
which included Imperial and AF, etc, so still have them. And added Metric
when it came along. Having the larger size BSW/BSF spanners, and AF, and
Metric means I've always got one which is a perfect fit to those plumbing
fittings. ;-)

I believe above above 6 mm the metric and Whitworth threads are identical in pitch. So the 5/16 whitorth would have been ok as it is.

There are some sizes of metric, whitworth and AC or UNC where the wrong
nut may well fit a bolt, etc. So ok for a non critical application.

Same with some spanner sizes.

Unfortunately not in this case, Almost fitted but I had to retap to get
the castors in.
