Ok. so I Think I got a "M" or maybe a "T" tank on the way soon. And I got this lil setup for next to nothin with a Western Model 840 reg. It will only flow 8 lpm so I wanted to convert it to my "refiller" for my E tanks and such. I already took the spring/diaphram out of it. Anyone know what else I need to do? Looks like I could drill the brass orfice out of the number 8 position, but the high flow of o2 might erode at the plastic disc. ANYONE?I figured this lil guy might be cool in the extended cab of the truck. Here a pic. EDIT: I'm gona junk this regulator. I found a really old one like I really need. Simple with threads on one end to connect a hose. PERFECT EDIT: I did drill the number 8 setting on this regulator, and put it all back together. NOW, when you click it up from 7 lpm to 8 lpm, theres a huge difference. Dunno how many lpm shes flowing, but its way more than 8. LOL  has a sound like 15 or more. Don't try this at home..............But it does work
