Another thing that occurred to me, since I have the HF gauge set too, is that the HF gauge set seems to be intended for someone who is doing home servicing of automotive air conditioning. The standard fitting on the end of the hoses (for automotive AC) is what is known as an "Acme thread". The long time standard in home and commercial HVAC is 1/4" flare fitting, which I usually hear being described as "standard fittings" or "regular fittings". There even seems to be a different fitting for systems that use R-410a... I think they may be 7/16" Acme, but I'm not completely sure of that. I do know it's different.
My local HVAC supply shop has every conceivable fitting adapter imaginable, and they aren't very expensive, so it's no problem adapting "regular fittings" onto Acme thread hose ends.
The manifold body on the HF gauge set has male Acme threads without through-holes so that you can 'park' your hose ends there when you're not using the gauges, and keep crud from getting into your hoses.
It all seemed like too much bother to me, so I replaced the non-through hole Acme thread fittings with regular fittings and ditto the hoses. It ended up being more expensive than a regular R-22 gauge set with regular ends, but that's the way it happened.
Short story: you'll need Acme to 1/4" flare adapters if your Schrader valves have 1/4" fittings.
BTW, I got some of these handy ball valves for my hose ends:
... they're nice but not necessary.
