Things not to do #41.

[Ian Stirling]

After examining your excellent new concrete works, discover that the flex for the concrete mixer goes through them.

[Roger Mills]

Is that *before* or *after* the concrete has set?

[Nigel Molesworth]

I assume your mixer now needs a new flex.

[Ian Stirling]

Thankfully, before. Last look round the site, to see if there was anything else I needed to do.

LOL you too ?

[Mary Fisher]

I predict a long thread ...

Lol. Well done!

My last mistake was designing a piece of wood to go where there was already another bit, and no neither could be removed or omitted. Quite tame.

When you've cut out a particularly intricate piece of lining paper to go around an obstruction, apply paste to the correct side.

Or when you've designed and etched a printed circuit board with the IC pins the wrong way round, so that you have to bend all the pins the other way up.

[Rob Morley]

Write 'PASTE' in big letters on the appropriate side :-) Likewise mark the scrap side when you're marking a cut in sheet material so you don't forget which side of the line you're supposed to be cutting to.

[John Kelly]

Or when you carefully cut a tile to fix around an awkward part of the sink discover you've cut it from the wrong side.

[Broadback]

Oh you do not know how this has cheered me up! I thought I was the only stupid D-I-Yer!

[Dave Stanton]

Or years ago, built a ZX81 on the wrong side of the pcb !!

Thats easy. Cut the flex and leave it for 'time team 3000' and fit new flex.

[The Natural Philosopher]

Ah,,thats like the classic mistake in model aircraft construction..two left wings...

My last mistake was in not realising that on a mains pressurised water system, although turning the mains off stops the water...flushing a toilet and allowing the ball valve to open will result in a loss of vaccuum and scalding hot water gushing out of the hot water pipe you have just cut off to add a new bit onto..until the tank drains down a bit too..

[The Natural Philosopher]

Actually the thing that gets me is the recursive installation problem.

I need to install the tiles to put in the basin to establish the vanity unit height in order to be able to accurately cut the piece of MDF that sits behind the basin covering the pipes and which has to go in before the tiles are laid...

[Dave Stanton]

LOL

[Mungo]

Is that not just a loop, instead of "recursive"?

Mungo

[Mary Fisher]

That sort of thing happens far too often for comfort :-(

[Eric The Viking]

To understand recursion, one must first understand recursion.
