Those are rat turds, way too big for mouse. Lucky you.
 
Any hvac experts?

I’d like to wire this to work. Preferably with a slow speed or two.
 
Under the dash of the 40? :rofl:
I'll let myself out now...

Certainly not in a 40… I’d have to remove the passenger seat to make it fit. Might fit in an 80 or 100 though.

Furnace fan for an HVAC setup.
 
Google has answered. Only thing I’m not sure about is the 120/240 wiring. C-1,2,3,4,5 is 24 vac control for five speed choices.
 
Our thermostat has a "circ" function so it'll just run the fan for 20 minutes per hour, with that 24v input you might be able to get something like that to work.

I'd build a box for it so you can put a filter in front tho. Kinda nasty what they'll pull out of the air. Especially with dogs.

Even if you're going straight exhaust it'll keep the vanes cleaner.

Just finished installing a new heat pump and a s*** ton of duct upgrades. I made the returns huge and the difference is night and day to the airflow. It's a smaller fan but it moves more air because it's not restricted like the old p.o.s.

That and the new unit doesn't sound like a car crash. Can barely hear the outside compressor... downright weird.

Job sucked to do, but I managed it for about 10-20k less than the average quote. 🙄🙄
 
Guy accepted my offer and then didn’t respond when I tried to set up a time. When asked if I could come now, he responded someone was coming tonight. He sold them to someone else after access my offer… and then didn’t even bother telling me. Not super impressed.

I had one electrician tell me it could take the tin guys up to a day per vent… at our office I watched them do 3 in less than an hour… go figure.

A filter is a great idea… I’ll have to see what I can figure out. Even if it reduces the crap it’ll be worth it.

A day per vent is a bit much lol




I cheated and used flex for the returns on our system. Found some 16" , and have 3 short runs coming into the plenum, oversized is good. Flex is already insulated so it saved so much time over doing it with tin and then trying to insulate it.

Freaking duct insulation costs more than the ducting itself. I found a bigass roll of silver bubble wrap stuff ( like you put on water heaters) on amazon, and that wrapped and stapled over some thinned out pink fbg looks good and cost a fraction of any other method I could find.

Opted for a hepa filter this time. I'm sure there's all sorts of s*** in our old house you don't particularly want in your bronchi.
 
Just learned about depression era uranium glassware yesterday. Realized I might actually have some and not know it. Pointed my (pet piss detector) UV flashlight in the cabinet and found three items that lit up good. Hard to appreciate in these pictures, but really neat in person. Took the plate to work and it hit 300 counts on the geiger counter (back ground is 10-20)!! Neat stuff.

Try gold. In the 60’s I think the US used a ton of gold for shielding in nuclear experiments then recycled it back into the jewelry markets. I’m told some of it is still radioactive enough cause a rash making some people think they are allergic to gold.

You got some I can try? :grinpimp:
 
OK, here's another thing that will give you radiation nightmares. Lab instructor at work informed me one of the nastiest things is old mantles from kerosene lamps.

So at home last night, I *carefully* collected fragments out of an old lamp/case given to us by my inlaws.

Got a geiger count of 9200+ with the tube up against the material. Through the glass it was 180. So lots of Alphas. You do NOT want to inhale that s***. But if your parents did lots of camping with you and you're born before the 80's, chances are you have already! LOL

Nah the ex cleaned me out of everything of value like that when she left.

Ironic that wedding rings can cause cancer.

Apparently there’s been other instances of contaminated gold getting back to the markets.


Is that lamp mantle radio active due to the gas? I have heard coal has a lot of radio active material in it, coal power plants are a source of radio active contamination, wonder if natural gas in your house is also? I know it’s loaded with heavy metals.

I would think it's negligible, because even though some old sites up here in Northern BC do contain NORMs (naturally occurring radioactive materials), most of them don't, so my guess would be that it would be diluted by the time it got to the end user.
 
Those old mantles maybe made of asbestos? Not sure. Saskatchewan has Radon gas in basements and low areas. I think to a certain degree this kind of radioactivity is pretty common when we heat and burn minerals. I work in upper atmosphere, so I wear a hat all the time. Keep airplane windows covered. I don’t sit out in the sun anymore.
 
@stevebradford @cruiserpilot The old lamp mantles are made of Thorium Dioxide. The string is Asbestos. I'd be WAY more worried about the Thorium than the Asbestos.... A geiger count of 9200 over 6 seconds is not normal.

It's true there are all sorts of radiation sources out there though. My parents tested for Radon in their basement in south interior BC, and hit warning levels. But they also have drill casing on the property from Uranium prospecting....so no suprise I guess.

@cruiserpilot A few years ago I designed an instrument with/for one of our students here in Physics. He was a pilot for Cathay Pacific (big jets) and was finishing his physics degree part time. The instrument logged Geiger Counts along with altitude/latitude/longitude. The counts got surprisingly high with altitude and latitude. I've attached the report (see link below image). Where sea level counts were 10, he was seeing up to 350 on some flights. Like this one for example (image from his report):

When I flew the Lear Jet about ~1500+M higher than that it burned the colour out of my ballcap in one summer. Sitting in
a giant glass magnifier. After 3 yrs the fabric had disintigrated. No protection up there, modern jets fly that high now, but
the glass is much higher technology. So far, fingers crossed, I don't have skin cancer on my face, but I got careful long before
it was cool to be careful. That is a cool graph.
Bust that machine out next summer on a hot clear day.
