  I cant find the 2" insert coupling anywhere. One i ordered from plumbingsupply.com is to short. No Lowes in the Phoenix area has it and they will not mail order one. Please tell me where I can find one.

  Looking at the article in print for the first time, I notice that they swapped out the 3" repair coupling that I used in the original. (Note to those interested; Make rebuilds at least SOME their projects, to verify them, and sometimes takes new pictures).
  
  A simple 3" coupling works fine to attach the air reservoir, nothing fancy needed.
  
  Also, the parts list (edited by me to introduce this particular mistake) lists two 2" to 3" reducing bushings, and there are actually three used in the body of the article (two modified around the valve, and a third that attaches to the air reservoir assembly).
  
  I think.
  
  Too many parts!

  You need to think outside the {big} box. Even bright shinny ACEs don't carry the 3" parts. However, try an dingy, old ACE with 1' wide aisles piled to the ceiling with goods, often in a mall void of other stores,... like at 51st ave & Thunderbird.
  
  They have all the 3" parts (3 newer ACEs didn't have any). Not only did they have insert couplers, they had them in every size. And there were 4 or 5 of the 2". The only part you cannot get there is the 2" o-ring, and that is because they only had 4.
  
  Oh and they cut the tubing so you don't have to buy a 10' stick.
  
  What they didn't have I was going to go 3 stores East to the Homeowner's Plumbing supply. Failing there would have been Sprinkler World up on Bell then SAN plumbing. Otherwise

• O-Rings and PVC Glue

  Two things I've discovered since the article:
  
  1) 4mm O-Rings work better than 1/8" O-Rings; they are slightly thicker, and you don't have to monkey around with filling the slot the same way. I used 4mm x 42mm rings, which worked but leaked a little bit, due to the excessive stretch I think. I want to try 4mm by 44mm, which should be nearly perfect (if they exist).
  
  2) The PVC glue used inside the sliding valve, binding the PVC pipe to the Schedule-80 PVC core, fails after enough use, causing the piston to come apart at inconvenient times (e.g during a photo shoot). I recommend filing all mating surfaces and using a strong epoxy instead of PVC glue.
