Is it safe to screw into a single support beam holding up an entire house?

First that post is not carrying the load of the whole house. The beam is and the beam is attached on both sides. The post's job is to keep the beam from sagging and act as a point load. I would ...

Can this 1930s box support a ceiling fan?

No. The bar isn't meant for this. It is attached to the bottoms of the joists, probably with small, rusty old nails. The box is probably attached to the bar a little loosely. Looks like rivets, ...

How do you mount conduit to a wall so that it stands off a standard box distance?

If you don't want to get a conduit bender, you can use conduit hanger clamps like the one shown below from Home Depot. The clamp fastens to the wall and holds the conduit away from the wall.

How can I temporarily support a ceiling with embedded heat tubing?

It's just not necessary to support the framing from above. Temporary walls are put up under drywall all the time, and the gypsum doesn't crush. Actual plaster certainly won't. Just use a 2x6 or wider ...

How do you mount conduit to a wall so that it stands off a standard box distance?

If you're using EMT and if wall-to-box offsets are the only thing you want to do (which is unlikely) and if you really don't want to learn to use a bender (or you're getting there, but slowly, and the ...

Is it safe to screw into a single support beam holding up an entire house?

At least in the area where I live, that type of support post is used when a house is modified (wall was removed, to prop up a sagging beam, etc). If the house was designed to have a support post ...

How do you mount conduit to a wall so that it stands off a standard box distance?

1\2" EMT lends itself to bending very easily. And incorrect bends are easy to "adjust." A little practice with a bender will have you making great box offset bends in no time. I will ...

Is it safe to screw into a single support beam holding up an entire house?

Notice the post is not just supporting the beam, it’s holding up ends of the boards that make up the beam! Would strongly recommend consulting an engineer ASAP and having the beam supported correctly. ...

Contact surface between subfloor and joists

Just add (nail, screw, and/or glue) additional framing material to the side face of the joist to provide more bearing area for the subfloor.

Can I use fine-thread drywall screws with wood framing?

It's fine. They are primarily intended for metal studs but they will work fine in wood. Think about the force required to physically pull out one screw - even a fine threaded screw. Now given the fact ...

Choosing the correct LVL beam size

Nope, a 2 ply 1-3/4" x 11-7/8" LVL can't span that long with this much roof on it. With a 19' span (and completely guessing on the roof span and live loading for your area) you're looking at at least ...

When confronted with that situation, I resort to a conduit bender. You can put a couple of small bends in the EMT . It takes a bit of practice, but it's really not all that hard.
