Hi,
Here's what I'm doing...
First some history...
I have a HUGE problem with raccoons in my yard due to a large sprawling park less than a 800 feet from my house. They deficate on my pool deck, go for late night swims in my pool, tear up my solar cover, tear up my lawn looking for grubs, eat my vegetables and do other things that raccoons do. Quite annoying.
I have tried everything imaginable and other suggestions through advise like cayenne pepper, mothballs, mint, and other solutions recommended by nature enthusiasts but the only thing that has worked is motion sensor sprinklers.
I have run a dedicated water line around my yard with taps at strategic locations where I setup these devices and control them globally with a water timer, on at 10PM, off at 6 AM. However, these devises are designed to cover a large area, like a lawn not a 10-12' x 25' pool deck and they spray high and far.
So, I have endeavored to make a more suitable 'sprinkler' or 'water application device' triggered by the motion sensor of these devices, that keeps the stream low and confined. (Neighbors complained about sudden streams of water coming over their my fence during their late night parties. Sheesh!) To do this I had to determine the thread used to hold a sprinkler head which is 25/32" - 14 (to my best measurement) which means I need to SP it.
Now here's the reason for this post....
When I set up my mini lathe to cut the appropriate TPI after turning the correct diameter and set the compound to the traditional 29.5 degrees, cross slide to zero after touching off, thread cutting tool bit mounted and set correctly, everything looked good on the scratch pass but, when completed, the threads had a saw-tooth shape rather than the nice V that I was expecting.
What did I do wrong?
PS: apologizes for the long story but the wife found it very funny so I thought you would too.
Michael.
