1) Research other clocks by searching the web. Get distracted by clips of funny animals and the people of Walmart.
2) Draw out your idea on paper and leave it lying on the table only to come back to it and find that your scribbled efforts have been put in the bin as rubbish by your beloved.
3) Order the materials you will need from the best sources which means waiting 3 months for that brass tube to arrive from China only to find out that it is absolute crap quality.
4) Plan the build of the clock and proceed in an orderly fashion only to find that the part you are holding in your hand at the end should have been installed at the start.
5) Decide on the type of finish you want to apply to the wooden parts, apply and leave to dry. When you return you will find various flying insects have expressed a desire to have a closer look and have adhered to the finish you have applied.
5a) Re-sand and repeat step 5.
5b) Repeat step 5a and avoid doing step 5a again by closing the door of the workshop when you leave it to dry.
6) When polishing metal parts on a buffing wheel make sure that you keep a good hold on them or you will spend the next 2 hours looking around your workshop to see where they landed.
7) When drilling holes in metal parts always use a sharp drill or you will find that the friction produced generates enough heat to melt your finger prints off.
8) After soldering brass parts together allow to cool sufficiently otherwise, when you pick them up you will experience the same effects that item 7 produces but on a grander scale.
9) When handling the nixie tubes always ensure that they are placed out of harms way otherwise that well known theory of Issac Newton will reduce them to scrap as they hit the solid floor of your workshop.
10) Success! After all of that you stand back to admire you creation and lacerate the back of your head on the metal sticking out of your overhead rack that you did not install high enough.
Now you are a Nixie Clock builder and have the scars to prove it!
Have a beer and consider taking up knitting instead!

A important step for tube collectors:
Buy a rare (nixie) tube from a surplus seller - and recieve your very own radar Beam Power tube! :)
