The small questions you've never asked.

Absolutely true, but I don't recall anyone actually stating actual facts back then. It was more a common idea that the more regs on your setup - the better. I mean, you must have seen the Classic Intimidators of the time with four regs on them, since they were the easiest markers to simply cram an agg-worthy amount of regs on.

Oh, and the four regs of course being a SP Maxflow on the tank, the OG Intimidator front block with dual front mounted LPR/HPR - and swapping the front grip for yet another HPR.

However, suppose you have 1% variation per reg. The first reg could be off by up to 45psi from a full tank to an empty tank. The second reg would then be off by only 0.45 psi.

Prior to pressure compensation (like the Pi and 2L regs) this would be a really big deal, especially for smaller pistons (like the Myth regs!) or sensitive guns.

[Olsson]

if you can regulate the tank pressure, why not just use the tank reg only instead of a tank reg and a HPR.
hell, why even have a tank reg/HPR and LPR. in the 1st place.

im sure there would be an easy way to make an externally adjustable tank reg if that were the case.

Yep, regulating the pressure directly from the tank, thereby eliminating the need for an HPR was a thing back in the day. As was having a whole plethora of regulators, with some idea of where the perfect gap between pressures was - but that's a whole different can of worms. Anyway, the initial run of both Impulses and SFTs were sold with a gas through, rather than an HPR as a grip.

Was Dye making a joke when they named their "throttle" HPA bottles the same word you would use to deprive someone of air by placing your hands around someone's neck and squeezing?

If they only made this fail/joke once, I would probably put it down as a tounge in cheek kind of joke. However, Dye also marketed their top of the line paint by proudly boasting in ads and on the very boxes "Perfect cylinders". Yes, really.

Well then which type do I have? The valve is after the fill nipple but, before the high pressure gauge. I found a manual online for the what Smart Parts calls the second generation, but that clearly has the fill nipple and gauge on different sides of the tank and the on/off on the other side after both of them (which makes more sense to me as then you can take off the regulator to work on but still see pressure in the tank). Is there like a generation 1.5 tank?

[DocsMachine]

The original Max Flows had the valve on the tank, so everything was depressurized once it was closed and the reg bled out.

Doc.

Mags were first used by an AGD sponsored team in the fall of 1990. I don't think they went on sale to the general public until early 1991, if memory serves correctly.

[glaman5266]

I have no constructive idea & no experience with a MaxFlo, so I'm just spitballing here- maybe it was simply because HPA systems weren't super refined back then?

[XEMON]

You have a point 👍
Might fit better/more compact?

[Euphie]

but surely if you were to degas your regulator for storage, it would seem dangerous for the tank to read 0 PSI in it, when it in fact has 4.5K right?

[XEMON]

Well, you don't really want to keep your reg pressured up during storage if you don't have to ...
Also if you have reg creep or a leak, you can close at the tank and degas the reg to not drain your tank.
This way you can keep playing and don't have to rebuild right aways ...

[Euphie]

On the original 4500 PSI maxflo, the on/off valve sits between the fill nipple and the gauge. This means that when it is off, the 5k tank gauge will drop to zero once the pressure in the regulator is lost.

Is there a reason for this? Was this a common thing to do? I can’t fathom why there is an on/off valve at all in this spot. It would make sense for an off on the actual output, but to be between the tank and the tank regulator seems such a confusing choice. I know the Gardeners weren’t stupid though so I figure it has to be done for a reason.
