Hi Mongo Bill,
Thanks for the recommendation on Randy's PA nva. I certainly will try it when I use it for it's intended purpose!
One of the things I use the ST NVA for though is as a spray bar for my combat engines. There I just remove the needle
and clamp nut, and solder the end closed. So how well that clamp nut and needle work together isn't important. But knowing the position of the hole in the spray bar is.
Thanks,
Chris
