I think I would use a couple of those boomless sprayer nozzles instead of building a long boom if i did it again. I was worried about drift and wanted to get the boom as low as possible to the ground and still cover the area. I took many trips up and down the driveway experimenting with different nozzles and boom heights.
I want to upgrade the pump to a 3gpm pump sometime but it works rfor now.
Here are somer pictures of my setup.

I have a FIMCO 55-gallon sprayer with a three section boom, and FIMCO recommends a nozzle height of 17" - 19" above the stuff to be sprayed. They also recommend a pressure of 20 - 30 PSI. However, my sprayer uses a 6-roller pump. I mounted a tennis ball to a piece of rope and hung it to the end of each boom. It sure makes setting boom height on the fly easier.
