The best way for re-usable fasteners is to mark the orientation of the fastener, loosen it and then torque it back up to a test figure and see if it reaches the marked point of rotation, loosen again and repeat with increasing torque until you get the fastener back in the same orientation. You won't...

The pedestal grinder in the first workshop where I did any tool grinding had a built in water pot, I can't remember but I think it was part of the stand.

Splinters are always more sensitive when brushed in the direction forcing them into you, I find that and then use a razor to shave the skin in the opposite direction, picking up and dragging out the splinter in the process.

I suspect that car fire statistics show that gas fueled cars burn far more often that battery powered cars.
And yes, SpaceX appears to be our leading space launch company, bar none.
More power to 'm.

But when viewed as a percentage of electric cars in use what do the stats look like?

I make springs that people want to buy BTW.

I have a bowling ball with a flat on it made with an electric planer and tapped holes on the flat. I sit the bowling ball in a golf trolley tyre on the bench and mount the vice or tooling plate of my choice on the ball. I can hold or clamp anything from a dressmaker's pin to a complete pistol with a...

Show your winding technique, not the results!
Otherwise we're guessing, but as a guess I'd say your wire guide is too far from the work and is allowing variable spring at the point the wire is being wound.

Also, if you use a 2-flute cutter, it won't deflect sideways when it is cutting the sides. This to me is a bit misleading, all cutters will deflect. That's why I specifically said "sideways". When the flutes are in contact with the sides, there is no cutting edge in contact with the end of the slot...

The instrument does, yes (unless you consider the standard cell part of the instrument, in which case it has only two). You've clearly confused a Leeds and Northrup type instrument with more general potentiometers which both pre-date and post-date the instrument, your argument that the instrument t...

A potentiometer has 4 connections?

If you want to get pedantic a potentiometer is a device for comparing an unknown voltage to a standard cell.

With how many connections?

That's just the potentiometer. The electronics must be in the motor. No it's not, and no they aren't :D Old sewing machine controllers were a stack of carbon discs which the pedal compressed via a spring to give variable contact pressure and thus variable resistance. A Potentiometer is a resistor w...
