Thanks to CJ, I now have a copy of Regulator Savvy. I will begin to obsessively pore over it soon. I also recently picked up the 1960 edition of Roberts' Basic Scuba in addition to my well-thumbed through 1962 edition.
Dunno yet about Reg Savvy, but I would definitely recommend Roberts 1962 (second edition) over the 1960 ed., simply because it covers more equipment. If you hide and wait to pounce, one can pick up Roberts at a fairly low price (<$40). I got both of mine <$30 each. Well worth the price.
What books are you all using for reference?

Regulator Savvy is a super in-depth and comprehensive discussion of how regulators work. I have started slogging my way through, and it is probably WAAAAY more than I'll ever need to know. But learning stuff can't ever be bad.

I suppose it depends on the kind of tech you want to be but for me, I disagree. Understanding how a regulator works and the reason the designer picked a certain diameter of a part or durometer of a oring had a big impact on the quality of tech you are. Any monkey can look at a parts diagram and assembly a reg but understanding WHY he can use one oring one place but not at another when they look identical is a totally different matter. A good tech understands why you can use a 70 durometer oring on a LP hose but not on a HP hose. Pretty much anyone can grab a bag of parts, throw them in the proper places and make most regs work but when it doesn't work properly, then they have no clue how to deduce what is wrong. IMO, this is the major reason so many regs fail shortly after service.
When you delve into the realm of restoring old regs or designing new ones, this becomes even more important if you want the regs right. Simply grabbing any old orings off a plumbing counter doesn't cut it, you must understand orings and sealing surfaces to do the job properly....and use the right one. While on the subject, another must read book (at least parts of it) IMO is the Parker oring manual, it is the bible of oring design. It's free at the Parker web site. If you don't understand oring and gland design, you really can't make informed decisions on what orings to use or how to design a seal so it works properly.
It boils down to do you want to be a high quality reg tech who understands what he is doing or a parts swapper who is guessing and hoping what he is doing will work.

Thanks for the heads up on the Parker manual. I'm checking it out!
