Okay, here are some additional details and pictures. I wish that there were more to explain about making this but it was seriously simple. First, I bought this item from amazon.com. (approx $25.00)
Then, using appropriate drill bits, etc., I attached the rocket hand pump to the lid of a small cooler I had.
Next, I made a trip to the plumbing section of my local hardware store for the parts to make two nipple adaptors fit to a threaded pipe, etc. as seen in this picture.
A rubber washer held by a metal washer seal the cooler so that water does not leak out. The fittings are identical on the inside and the outside of the cooler.
Then, I simply used some plastic tubing to connect the rocket hand pump to the nipple inside the cooler. I used a good amount of this tubing so that I could coil it up inside the cooler to increase the amount of beer that gets in contact with the ice water - but not too much that the beer gets below about 45 degrees.
On the outside of the cooler, a piece of tubing goes to a beer connect for my corny keg.
Once it is attached, I unscrew the poppet relief valve on the corny to let air in. I have thought about attaching my CO2 tank at about 1 lb of pressure instead so that no air comes into contact with the ale, however, some oxidation of the beer is actually authentic and desireable for many real ale enthusiasts.
That is about it.
I recently made an upgrade of putting a sparkler on the spout. I used a nipple adaptor, a bit of tubing, and a compression cap after I drilled some holes in it. Here is a pic.
