Water column and inches of mercury are two widely different scale ranges. A stove would barely make an automobile engine vacuum gauge needle twitch off the stop pin. And a car engine would such a mano gauge dry just on the first few turns of the starter motor.

.04 inches of water column equals .0029 inches of mercury.

Cursing speed on a level road for most car engines would equal about 240 - 250 inches of water column.

"cursing speed" ?!? I gave up driving when i'm THAT pissed off yrs. ago

You must be talking about this Steve. They were installed in full size Pontiacs of the early -mid 60s.

that's the one. weren't they diaphram regulated ?

Diaphragm regulated ? Do you mean the secondary's on the four-barrel carburetors, or the vac gauge ?

Most mechanical vac gauges are Bourdon tube type mechanism.

Paul

Can't say I ever remember taking a vacuum gauge apart, so how the needle is "swung", from the rubber vacuum hose connection, I don't know.
Paul, I know the mechanical water temp gauges were Bourdon tube activated, and the mechanical oil pressure gauges took direct forces from the oil sent to the gauge, but are you saying internally, the needle is attached to a Bourdon mechanism?

Joe,
I have a bunch of vac gauges that I use in my work, including the first one I ever owned that came out of an early 60's school bus. All bourdon tube. As are my Gov. surplus lab grade vac and pressure test gauges.

The cost of producing that type gauge for the accuracy they are capable of is why they are so common. I'd be very surprised to find that GM put any other type of mechanism vac gauges in production cars. After all, it was the 60's.

joe I had a 76 full size Pontiac, with a 400 2 bbl, had an indash gauge just like the one you showed. I never paid any attention to it. wilson

yeah, the concept was kind of alien back then wasn't it ?

Hey Wilson, was it factory installed, or did someone chop it into there? I'm not sure Pontiac had that option in the dash those years.

Actually Steve, vacuum gauges were installed in quite a few applications in the 60s, and probably in the 50s too, tho I can't think of any off hand. Maybe you more "experienced" members could elaborate on this. It's todays cars that lack this option. But then again, the digital cars have electronic MPG read-outs, which I'm sure at least one of the signals are derived from manifold vacuum. In earlier years, you could buy aftermarket gauges that they called "motor minders", (which read vacuum). When you stomped on the gas, it would read "poor", but when you let off, and vacuum returned, the gauge would swing up to "good". (Very high-tech.)

Hey friends well Its 42° tonight and 40's tomorrow so Its 1st fire tonight , didn't take 2 hrs to get It going as It was a breeze doing so no problems what so ever! so far I'm running around 240° on the barrel in base mode with the MPD at 3/4 closed ( I have a slight wind going on outside) and I can feel the heat crossed the room ( very happy but It's very early In the game) now come the learning curve with the air and MPD settings begin!
I was playing with the MPD and was taken back on the effect It had on the draft, full opened I was pulling .08 but with It closed 3/4 It went down .05 and when I closed It all the way It dropped to .04, I will need to play with that but for now It will stay at a 1/2 or 3/4 closed.

looking really good KY. Can't wait to get my 111 going, hopefully soon. I only started burning my heater last season, (and still learning), but found the slide damper wasn't nearly as "reactionary" as the MPD. I'm sure it does have some effect, but the MPD was much more responsive for controlling heat output, than the slide damper. Increasing the MPD opening, gave more draft, which resulted in a hotter fire.
Will you try any stove coal in your G8, or does it like nut better?
PS, Is the stove above your 8? I pictured the pot much bigger than it appears. Maybe a ruler would give a better sense.

Joe, I started It with nut but finished the fill with stove, the last load of nut I got was on the small side so I may mix the nut and stove until I'm Into the stove only.
I got up at 1:30 this morning to check on It and the barrel temp was 248° pulling a .06INWC so I closed the MPD all the way, I checked It at 6:00 and the temp was 289° pulling a .04 INWC, never changed the primary settings which Is at a 1/8". I think the size of the #8 was a good choice for my house, It's 36° out and It's 76° inside no fan noise and the stove Is just above idle I am glad I added a second MPD, I think I will be needing It when the colder weather gets here! so far I'm amazed at the controllability of the stove ( I'm sure the seal on the ashpan door Is a big help)

You can get a size reference with the indoor bin( which I'm going to remove and just use a coal hod) It's a plastic 55 Gal drum.

Yep, fantastic stove. I have not even lit mine yet and I am getting inspired.

So glad it is all working out so well for you Barry.

Congrats Keepa. It looks even better now !!!! As William would say, welcome to coal easy street !

Yup, don't hesitate to play with the dampers and watch what the mano does. You'll be further amazed.

If you have the check damper elbow, try adjusting that too. You'll be surprised to see how well it can tame a strong drafting chimney system, yet it doesn't impact the draft negatively as much as some might expect. One of the reasons check dampers were included on so many stoves and ranges.

Keep us posted on your progress.
