How to build a pressure tester for your Bob Long Vice or G6R:
For many owners of the Bob Long Gen 5 and 6s, we acquired our markers used, or could simply not get our grubby mitts on a pressure tester for our LPR. With some patience, minimal skill (can you tighten a bolt?), and some used parts most of us have in our parts bin, you can have your very own pressure tester!
Gauge (0-100psi should be plenty, 1/8 npt threads)
1/8 npt female-female coupler
Straight or 90 degree macroline fitting
At least 6" macroline
Connect the female-female coupler to the gauge ensuring a snug fit. Use one drop of blue loctite on threads of the gauge before screwing together to help prevent air leaks.
Now apply a drop of blue loctite to the threads of the macroline fitting and screw snugly into the other end of the female-female coupler.
Push your macroline into the macroline fitting.
The macroline takes the position of a factory pressure tester, fitting snugly in the ram tube. Now this is the part where it is nice to have a few different types of macroline handy. If air leaks out around the tester when doing your adjustments you will need to change out for a thicker OD macroline. I have always had luck with the softer, thicker walled macro as opposed to the thin, stiff stuff.
