George Dive kit packed so nothing much to do other than ponder... Just checked out the URLs and noticed your 17% He over pump from the "ideal" pressure. Generally, I over pump all the gasses by 10%, O2, He and air in that order. I hot fill and get very good results. On the two occasions I have bothered to analyse the He, when the O2 was spot on, I found it to be 3% higher than target percentage (assuming the He analyser is correct!!!). Not that it matters much as too much Helium is a tortology, but have you analysed the Helium after over pumping 17%? The other curiosity I have mentioned before is that the O2 takes some time to stabilise (often up to 6 hours), but I have a set in the garage pumped 36 hours ago. Either side of the (manifolded) twinset is still analysing differently on O2 - only 18.8% and 18.4% gauge which is neither here nor there and will eventually diffuse. (Sorry John.) However on leaving the shop it was around 11-12% - I only ever get this with Trimix. I've had long debates as to why this occurs and suspect it to be the viscosity of the gasses under pressure acting similarly to liquids rather than gasses. Any thoughts?

Do not write "MOD" or "Feet" or "Meters" or "50/50" or any other nonsense. See http://www.wkpp.org/articles/Gear/equip_gasandmarking.htm for the entire correct way to do all of this, and see the pictures at http://www.wkpp.org/articles/Gear/equip_moreimages_3.htm for examples . In your case, obviously, the numbers would be for meters not feet, but there is no need to indicate that as it is dead nuts obvious. Read the whole discussion on my web site and you will see why this is true.
