Unless 1) our labor is worth only a few pennies per hour or 2) you want to reinvent the 
wheel, or 3) you want to turn this into a science project, I STRONGLY suggest that you 
proceed as follows. 1) STUDY the Fair-Rite catalog. 2) Choose the parts that will do you 
job. 3) Do a search for distributors on their website, and ask for a quote on some 
reasonable quantity (20-50 is a good start). I strongly suspect you will be quite surprised at 
how cheap they are when you don't try to buy onesey-twosey. And if you have chosen the 
parts well, you will find lots of other uses for them both in your own home and those of your 
friends.
