I thought the threads on my Mvp went bad so I bought a ego to 510 connection.I find out I apparently buggered the first thread on several of my aerotank bases. The mvp is fine I found this out by screwing a kayfun to my mod and it was fine. My question could I repair the aerotank threads with a 7mmx.5 die?Or do I have to buy new bases? Thanks, Dave
