I'll record the sound of a Geiger counter for you,

 

[denata]

Recorded the sound of different dosimeters. one from the 60-70s years and modern. Listen and enjoy.

The older unit is a tube type ?
It should continue functioning even if a magnatron bomb is set off.

 

[denata]

Yes it is, there are no transistors, everything is on vacuum tubes. It will survive any cataclysm of any magnitude. Even when the machine gun melts and molten metal drips onto the soldiers’ boots, this device will tick and move the needle.

I have two old vacuum tube (I had forgot thats what they are called) radios.
The one is a large model with a turn table and the other is a table top unit.
They both function flawlessly and has several bands including short wave.
I should string an antenna and tune in to see whats going on out there in the world.
Would need a translator though.
I suppose there are voice translator devices that could be hooked to them then broadcast into headphones.
I have also saved the points ignition distributor for the 1959 Dodge W100 318 V8 engine, Just for the just in case.

 

[denata]

I have one too, just in case.
For GAZ66

We know the newer ones are more accurate usually- but there’s just something about that different tone from the old one that makes it feel more serious.

Continued underground concrete work, Filling the floor in parts. Yesterday evening I mixed about half a cubic meter of concrete. Filled a 9x7 foot area. 4" thick. The dungeon doesn't look very presentable now, it will be more beautiful later.

I welded a chimney from 108 mm (4 inch) pipe. The horizontal sections were pitched at 8°. To extend the chimney from the basement and through the wall of the upper garage, I used four 90° elbows. The two horizontal sections of pipe have a drop of approximately 5.5 inches per yard.

Hopefully you can get a chimney brush through it?

 

[denata]

if the toilet brush doesn't fit through, we'll have to use the M-80.

 

[Will L.]

I don’t know chimneys, but wouldn’t it be better to use two 45° fittings?

To help limit creosote growth, an occasional flash fire (once everything is already good and warm) to burn the creosote can work. Same idea as a controlled forestry burn to prevent a larger fire. But, if the creosote is thick, then you will get the equivalent of a destructive forest fire.

So, while a preventative fire can prove effective, there is an art to its execution. If those pipes are not able to handle a brief creosote burn, then it looks like you are stuck finding the best toilet brush.

Or, look around for a gassification burner. Near zero creosote. But it will need occasional cleaning of ash build-up.

In plumbing, this is what they do – 2x45°. A chimney slope is necessary to allow condensation to drain away; much less condensation forms if the outer (street) part of the chimney is insulated. When the chimney is heated, moisture leaves the chimney as steam, but when the chimney is cold, the steam condenses on the inner walls and flows back into the furnace. The amount of this moisture is negligible, but if the slope is not maintained, over time, the condensation, along with soot, will turn into a tar-like mass and clog the chimney.

Aspen firewood is typically used to burn off soot; it produces a lot of sparks that rise up the chimney and ignite the soot inside.
Aspen also produces high temperatures and does not contain resin.

 

[ak diesel driver]

I never used to brush the chimney in my shop. I just let the occasional induced chimney fire clean it. Then I installed a 6" diameter 1/4" wall steel pipe for the chimney. I couldn't get it to ignite.

When the chimney is vertical, there are no problems with it. The problems are with the roof.
