Nitrogen "Unsafety" needle first test.

The Fox needle is safe, but it's also expensive and ineffective if used as directed (i.e. with a Schrader valve connection to the gas supply). The volume of an IFP chamber is so small and the pressure so high that you inevitably lose about 80lb of pressure upon disconnecting. When you couple that with the fact that their needle is NOT repairable, making your own begins to make a lot of sense. This one works beautifully and you can still fit the cap over the needle to make it poke proof when not in use.
