Please be sure to include the following vital ingredients in all of your planning:
3 x adequate quantity spare time
1 x dash of patience (saintly version recommended)
2 x tins of good quality elbow grease (large pack)
1 x clever plan
2.5 kg of bold and cunning nature
1 x understanding, loving wife (if married)
1 x packet of head scrathers
4 x box of "make-a-plan"
Number of a reliable electrician (preferably close by)
1 x fire extinguisher (for those of you making a plasma cutter near the part of your garage where you keep the fire wood!)
