THOU SHALT / THOU SHALT NOT

[SteamKit]

Oh!

Thou shalt not mix water with molten metal. Kaboom!

Thou shalt abate thine instinct to catch unfragile items that one has dropped, if they are hot.

Thou shalt consider the accumulated pressure when applying heat to thine workpiece.

The latter's happened to me personally, used the bottom of a popcan as a mold while melting some lead, and the can kept melting so I got the bright idea of filling it with water first, and capping it off. Heated it, and woosh, in a gush of scalding water it shot into the air, crushed itself, and burnt me badly because I did not obey...

Thou shalt wear a shirt when working, especially with hot things for like grapefruit to thine eye, hot things shall seek one's nipples.

-Kit

[Haizea]

Thou shalt be wary when brazening metal together with a blowtorch, for frequent pops and sparks will land in thy lap, and burn holes in thy trousers.
Thou shalt NOT carelessly brush thy hand against the soldering needle, for even unplugged thou shalt burn a hole through thy flesh, so that the bone is visible.
Thou shalt generally avoid any form of soldering if thy name is Haizea, for thou will inevitably injure thyself...

[Mad Maxine]

Thou shalt:

• NOT apply spraypaint inside the domicile;
• Close all cupboard doors immediately after opening (lest your co-worker smack you upside the head);
• Learn to cuss in a fluent and efficient manner so as to efficiently, by catharsis, diffuse all pains acquired while tinkering.
• 
  

[George De Vraic]

Thou shalt:

> Count of the fingers before and after the holding of the fiddly bit and the adjusting with the heaviest 'adjuster' in the shope.
   
> Extingush and remove the head torch before retiring to one's bed chamber or co-adventurer shall mistake this false dawn and will crow merrie hell and take the peace.

>Learn thyself not to use the sticking out of thy tounge, whilst apllying the cutting tool. (Though verily, one should be left to be one's own master in one's own Laboritory-  even if one looks 'simple' or 'touched in the head' and the co-adventurer takes the peace.)
 

[Commander Obadiah]

Thou shalt lay a drop cloth over thine freshly painted motorcycle frame before painting said motorcycle's bodywork.

Commander C. Obadiah

[von Corax]

Thou shalt bear in mind at all times that cold brass is indistinguishable by sight from that which is burning-hot.

[Commander Obadiah]

Thou shalt have a minimum of one beer in the fridge ready to be served BEFORE thou shalt attempt the job at hand.

[SteamKit]

Thou shalt have a minimum of one beer in the fridge ready to be served BEFORE thou shalt attempt the job at hand.

Thou shalt also partake in moderation, for drink can steady the nerves but unsteady the hands, and fool the eyes into thinking thine thumb is a nail.

-Kit

[Marrock]

Moderation?

Isn't that a town in Pennsylvania?

[SteamKit]

Yes, yes it is. A quiet little Amish village. Ever been there?

-Kit

[Marrock]

Nope, because according to Ernie Kovacs there's "Nothing in moderation."

[Alexander Edmund Clough]

When thou art turning down an lenght of aluminium rod to a known diameter, thou shalt always ensure that the finishing cuts are made very very very shallow indeed, and thou shalt take frequent measurements, lest thou turn it down to 0.2mm too small.

Thou shalt marvel at the amount of swarf is produced when thou dost clean thy lathe.

[Sir Nikolas Vendigroth]

Thou shalt marvel at the amount of swarf is produced when thou dost clean thy lathe.

But shalt not brush it up with thine hand   

[Armored Rah]

Thou shalt make many divine rules, but remember few, so it is written..

[Dr Flonker]

Thou shalt make every effort to appease Murphy in thy planning and try not to freak out too much when He shows up.

[Jennette Haber]

Murphy: god of projects

[Dr Flonker]

Murphy: god of projects

Thou shalt not sacrifice thy neighbors to Murphy, no matter how much they richly deserve it...

[Jennette Haber]

thats what the blood offerings mentioned earlier are for

[SteamKit]

Thou shalt not sacrifice to Murphy at all, for he chooseth his own sacrifice from thine projects!

-Kit

[crazy eyes]

Thou shalt keep an icepack, large magnet, butterfly bandages, superglue, and tweezers together in a obvious place. For they will save thee many doctors visits.

[Sean Patrick O-Byrne]

Thou shalt speak proudly "Stitches are for sissies!"

[Haizea]

Thou shalt therefore acquire many injuries, and thus many gory stories to tell freaked out/fascinated people later.

[Hektor Plasm]

Thou shalt speak proudly "Stitches are for sissies!"

Therefore:-

Always make sure you know where your superglue is....

[Herr Döktor]

Thou Shalt take notice of how much gas is in your workshop heater; Thou Shalt Not continue working as it sputters and gives out noxious fumes.

Still, the headaches going now.

[Ben Hudson, Esq.]

Thou shalt not suck vigourously on small deep stab wounds, for the suction is prone to make internal fat layers become external until they are poked back in.

That said, thou shalt always suck on cuts (not each others')
