    I needed a SINGLE ball bearing to fix a capacitor on an antenna tuner. Just ONE little steel ball to go on the end of the shaft where there was a little divot for the purpose. I went ALL OVER TOWN to find anyone who had a steel ball. You can still find a radiator cap for a Model A in this town...but a steel ball? No way.
    Well, I found ye old sports store was selling flagons of BBs in the handy 2500 BB size. So I thought I'd give it a try...they were ABOUT the size I needed. But I only needed one, not 2500. So now I have 2499 copper clad BBs excess to my need. I guess I need to re-acquire a BB gun again.

    Now you know.

    I learned a long time ago, when I take "stuff" like that apart, to put it in a cardboard box with the top removed and work thru the opening.

    ESPECIALLY antenna rotors, those ball bearings don't get away.

    Well, the ball was missing when I inherited the antenna tuner. I'm pretty good about not losing parts. Most of the time. Occasionally.

    ABSOLUTELY!!! Same here - anytime I take stuff apart that potentially has "small easy to lose bits" I do it over a plastic tub that's way bigger than the item. ANYTHING can fall down but will be caught.

    The folks that do the spacewalks in the ISS and such use similar techniques - "capture devices" to keep bits from falling up, left right down or wherever in the weightless of space. We only have basic gravity to deal with :)

    Oh, and a really important lesson I learned - NEVER EVER EVER take anything apart with tiny parts over a gravel driveway :eek:

    Like the magnetic trays that come in various sizes. When taking a rig apart it's great for the nuts, screws and other hardware. Assuming they are magnetically attracted. Harbor Freight often has them on sale.

    Get a magnet, wrapped in in kitchen towel, n get down an yer hands n' knees. Now, ya wondering why I said wrap it in kitchen towel eh? Ya' could tie it to piece of string and drag it along.

    Well when I'm on mi' hands n' kness I usually pick wire clippings, nails n' screws up - everything but what I'm looking for...!

    Removing the towel is a darn site quicker than picking em' off one by one.

    A "flagon"???:D

    For many years I really enjoyed restoring small Japanese diesel "rice tractors". One was a great little 4WD Hinomoto painted orange and sold as an Allis Chalmers. One of the front wheel 4WD pods/ball joints needed a new seal. It was about a 4-5 inch cast iron two piece globe. I got it open and a couple of hundred ball bearings spilled out. They were not in a bearing race. They resided in a very shallow channel between the top and bottom hemispheres. I think the service manual listed 200 balls in the assembly. After replacing the $2 seal, I filled the channel with heavy grease to hold the BB-size bearings as I pressed the upper and lower units back together. I put as many of the BB size balls back in the channel as I could find. It was only about 100. It still worked perfectly for at least another two years before I sold it.

    I'm sure the owner of my old workshop is still finding little ball bearings whenever cleaning the slab floor.:confused:
