    Fortunately, the Earth is not a closed system. We are bathed with a constant supply of free energy. Ask any plant.

    Too bad the misunderstanding doesn't work in the other direction. Where are my nobels and genius awards?

    Air conditioners work by recirculating inside air. The condensation comes from cooling the air inside, not outside.

    Traditional wheel cutting engines used a large brass plate for indexing. Watch & clockmaking are very different things. What are you trying to do?

    Seems to me that the op was being generous with his knowledge and time. Nothing wrong with that. I have benefited in my life alot from the generosity I've received.

    Burn the fing thing and forget about it. All the previous post are about employment and contracts. This is a trap.

    Whatever you do, DO NOT sign anything.
    Sounds like some crazy scam/legal trap.

    MDF faceplate?
    Mount a piece of thick MDF to a faceplate and turn a recess that the gear fits into snugly. Take light cuts.
    I do this when making new clock wheels. After cutting the teeth, cut a...

    Sigh,
    These are exactly the kind of stereotypes and misconceptions that have stigmatized hemp and cannabis. Hemp is an incredibly useful plant and we have cannabinoid receptors in our brains,...

    Python? I would rather figure out how to use a slide rule instead.

    This is hardly even a trig problem except knowing the Pythagorean theorem. Draw a diagram and apply a little algebra. It took...

    Yeah, thanks i just realized that's what the op meant. In that case ,

    Check out the Spica mechanical fuel injection system used on US export Alfa Romeos from about '68 - '74?. I had a 72 GTV with it and it was a spectacular example of mechanical engineering. Based on...

    What i want is a #4 with the horizontal mill on the left side of the headstock. I have a regular #4 which is a beautiful machine, but with a mill and dividing head it would the bee's knees for clock...

    Note that much of the efficiency of LEDs is wasted in having individual power supplies for each LED. There is no need to run mains power to every light anymore, rather use a constant current DC...

    What color is the ceiling? I would use a combo of upwash lighting and spotlights. Bright upwash lighting ( pointed toward the ceiling) can provide nice uniform background illumination. Use LEDs and...

    It's probably called pinion wire as a holdover from the days when clockmakers used it. It was made in module sizes using drawplates. Not modern tooth forms, however.

    Interesting. What i thought were pin vices are also cutters. They look as if they were made to only cut to a certain depth, so maybe cutters for watch jewel settings? What you have doesn't look...

    What is the width of the base and center height? My guess is that it was made to fit an american pattern watchmaker's lathe. Looks like watchmaking tools to me. I see some adapted pin vices, 2...

    Does the origin of the word 'dog' in machinery have to with teeth like a dog clutch on a lathe?
