Funny, I feel exactly the same way. Never done anything like this before and thoroughly enjoyed it. Learnt so much about machining, injection moulding, laser cutting, argon cutters, cnc, aluminium construction, gaskets. 
  
I actually went into te factory of the anodisers as mentioned above, very interesting..... 
  
Oh and guess what..... 
  
  
They anodise the bolts for Pro-Bolts. This is to our advantage as I'll be following the same colour swatch for their bolts so that anybody who purchase Pro-bolts will have an exact match.  CLASS!!! 
  
Ooooh I could crush a grape!! 
 
Nice one buddy, hope it all works out well for you
