    Do people ever show you a draft of a print and have you give input on tolerances?

    I have a machinist friend I can bug (don't worry, I do his electrical) but many people don't.

    Mainly since when...

    I don't have a hard spec on exactly how clean the hole needs to be. I suppose clean enough that I can cleave and lap the fiber without breaking it off below the surface.

    The minimum thickness is...

    How large of a spot size would be needed? I'm hoping it could be maybe 0.003" wide so I don't have much chamfer at the entry. The exit doesn't matter at all, but sharp, clean corners on the entry are...

    I could farm it out if I need to. I just don't have a perspective of dimensions in this range so I'm not sure what approach to take, though this thread has certainly helped.

    Straightness only needs to be so so. I would like to use aluminum but I don't know if I can lap the fiber flush to it without contaminating the fiber. I do know stainless is no problem.

    I will...

    Drilling 0.005" hole

    I'm getting into fiber optics and would like to make a ferrule with a 125 micron hole (0.005" or so) for coupling the fibers. Once secured in the ferrules the fiber will be cut and lapped flush, and...

    Those high capacitance small size caps pass a lot more current and have higher resistance, so dissipate an exponential amount of power. (Assuming his capacitors are physically small).

    Be aware that the higher capacitance a single capacitor has the more heat it is dissipating. If you have high capacity, physically small capacitors they'll have a worse service life.

    The voltage rating isn't great, but I think the amount of starts per hour is the bigger issue. It's passing too much current for too long for it to handle. How much capacitance does a single...

    Why would you ever do that.

    Our supplier accepts pretty much any bottles for exchange. We "own" our bottles but that just means we can keep whatever ones they exchanged indefinitely without paying.

    Where did you point the torch? If they were both in the hot gas from the torch the small parts will heat up far faster than the big chunk of outer metal.

    If it was heated solely through the outer...

    Anecdotal but I like 220 grit aluminum oxide for finishing aluminum prior to clear anodizing. It gives a nice smooth finish and a uniform dull gray color for minimal effort.

    I bet that would be a...
