comment Cutting structural steel
Okay, but how would you combine this machine with a horse such that they are both on the right height?

Nice thing except it requires a large table for dealing with long beams.

comment Cutting structural steel
Grinding can heat steel and cause tempering. I wonder if that can be a problem for structural beams.

Btw adding expanded clay may well help you save a lot of money on cement.

comment How can I lift buckets of mortar to second floor?
With 20 square meters and 100 buckets it's ten buckets per square meter. That's quite a lot of mortar and the layer will be rather thick. You could perhaps save a lot of weight by either lightening the material or by using two layers. One option is that you add expanded clay to your mortar and use the resulting concrete for everything except the upper layer and the upper layer (made of just mortar) can then be like 20 millimeters or something. This will save you a lot of labor - easier to mix, easier to lift, easier to handle.

comment How to diagnose an electrified refrigerator frame?
@skybreaker: That happened a lot and happened to me too. The shock strength greatly depends on other conditions - if you're staying on dry floor with dry slippers on your feet it's almost never strong enough to feel it yet a voltage indicator will light up no problem.

comment How to diagnose an electrified refrigerator frame?
@skybreaker: It depends. If the device has "double insulation" accompanied by a square inside a square pictogram somewhere in the spec - then it is guaranteed to work just fine without grounding. Power tools such as drills typically have that. Otherwise you have to ground the appliance to prevent being shocked when touching it. That's not specific to new aplliances - old stuff had to be grounded too but 50 years ago people didn't care about electric safety as much as they do now.

@skybreaker: I'd say "yes", most likely.

comment How to drill a minute hole on a wooden pendant without a drill?
I have to add that the black thick thing on one of the ends rotates freely so you can simply place the drill bit where you want to drill and then press it with your index finger and use the other fingers to rotate the rest of the thing. This makes drilling a straight neat hole much easier compared to holding the bit with pliers of needle file holder.
