   I'm on various lathe and metalworking groups, and with a whole lot of   
   unfinished projects, so I had no problem. :-)   
      
   BTW. I assume that the cheapest kit I should be getting from Caswell is the   
   "Electroless Nickel Mini Kit (5 Pint)" since I'm a beginner, correct?   
      
   Thanks.
