Seems a few of us are restricted and shed-time is out.
Here's my worst tip: get in a few of those books or mags titled something like '201 shop tips, tricks and jigs'.
I've now got over a 1000 tips and tricks, and they're riveting reading for a while, but can I recall many the next day? Nope.
Some time later I'll recall there was a solution to a prob of interest, but finding it again? No chance.
