In BC we have only recently found archeological and geological evidence of phenomena and practices that First Nations have maintained as oral truths for thousands of years- imagine how much was erased with disease, other murder and cultural erasure.

Ancient Comox fish traps, sunken undersea gardens….

Clay liners are typically just stacked and laid in place while brick goes up surrounding them. I’ve done a few stainless liners- the upper termination just sits on top of existing chimney. The pain in the ass part is getting into the side of the flue down low- you need a good hammer drill with chisels to slope the flex liner up and to mortar around the liner, setting a termination ring in place, you need your wye fitting to the two appliances to be at a safe height above both appliances and you should not use appliance with powered vent when the other is natural draft- ask a plumber if they will let you snake the liner and have them do everything in the basement.

By one of several possible originators, this information is being carefully curated for our consumption. Ma could be long dead and there’s a need to make him “live on a little longer;” he may be in Vegas playing blue whale; Japan may have agreed to help obfuscate a vacation to Cancun with the fam; he’s still getting premium re-education at Camp Hunny; nobody knows where he is but he’s given Japan et al carte blanche to troll his minders… Statecraft is fun for the whole family.

I mount machinery to walls- similar situation. We drill the mounting holes, insert the anchors and then use Devcon Plastic Steel as a bedding compound to evenly distribute force. For something like a pullup bar, PL Premium or Premium Max also makes an excellent bedding compound and has the compressive strength, workability and ease of application you want.

The old fashioned solution is Rockite- it's used for bedding machine tools but it's not perfectly waterproof.

Boilers should fill automatically with makeup water. You do not fill them by other means.

Read the boiler manual- if you bled the rads, did you just open bleed valves at each one until there was no air? Or did you see water pouring out, it slowed down and then stopped, indicating zero pressure? If the latter, the boiler may have sensed a leak/low pressure and shut down so you have to restart it- it may have closed a solenoid that shuts off the line to the front-mounted gauge on the boiler. Did you lock out or shut off the boiler when you did this? There should be an automatic spirotop-type bleeder and you shouldn't need to do this at all; there is almost certainly one in the boiler- Viessmann boilers tend to accomplish every feature within them. But these things can get deposits in their vent and become blocked- a plumber needs to tend to that. Don't monkey with a fancypants boiler like this.

The grey hose and corrugated line all leads to drain- that's where excess pressure/condensate, etc. goes. You have 7 bar of pressure in the supply lines- did you close that angle stop handwheel when bleeding the rads and forget to open it?

Some gauges are not reading all the time and need to have a valve before them opened to read pressure. Does this boiler heat your tap water via a pump and heat exchanger in another tank and also feed your radiators? are you sure there are no other lines coming out of the boiler?

Lashed to the pilings. That’s why the traditional timber versions of these vessels are so regionally-specific, with a keel and ribs strong enough to support repeated drying, broad enough abaft the beam to to rest upright on grounding, hold her catch and be able to surf home in a following sea but still with enough deadrise to keep way and break sea to prevent her from pounding herself to bits.

This is a conventional two piece toilet. No wall-mount whatsoever. Upper tank to base uses two bolts, two nuts, two spongy big fat washers twixt the two porcelain parts , two harder washers under the nuts and sometimes one or two spacers to prevent tilt as well as one Very Big Spongy Washer that does the actual water seal twist tank and base.

Yes. The only constructive consensus for healthcare is that every person is an individual with unique strengths and challenges. There cannot be a universal solution for nor should there be over- broad categorization of individual struggles.

It's the levers you use to wind the springs or the wrench you use to tighten the 2-3 locking setscrews that cause the most common injuries. The spring is wound on its shaft by a capstan with radial holes and you wind it by putting two levers in the holes- one to hold it and one to advance it. if the capstan's light aluminum casting breaks or your lever slips, the next one comes around and takes out your head or impales you- the same thing can happen if a lever slips while you are locking the bolts and the wrench you are using takes your hand off or winds up inside you. All compounded by the fact that this typically happens to a DIY amateur standing on a ladder.

I've seen the springs unwind unexpectedly a few times but I've only seen two springs break and one of them just violently unwound on the shaft as you suggested but the other one threw a section of itself through 2 layers of drywall 60 feet away. I'll never touch another one.

Tracks are for rollup or torsion spring doors- tilters and floders use pivots counterbalanced by tension springs.

You have the door up, you arrange a rope each side taking the load each spring holds and you use a pulley at each rope so you can safely raise and lower the door and hold it anywhere you want with the ropes.

With the door secured by ropes you can now remove the redundant and relaxed springs. Usually a clip, cotter or hitch pin pulled to remove a pin or link and then the spring hangs free. Not dangerous as long as there is no load on the springs as they store no potential energy.
