Bugger, broken drill bit...
--If you can, weld something onto the end and work it out that way.

Bugger, broken drill bit...(now: Coin deposit shopping carts)
Stormin Mormon wrote: I've seen the coin release carts at Aldi's, but not any where else. It's a deposit, not a fee. You get a quarter back when you leave. I know that, but it requires a second trip to the store to return the cart. That doubles the trips from my truck to the store and back to four trips, and the chances of getting hit by some asshole talking on a cell phone or texting while they drive 20 MPH past the entrance to the store. I can't move that fast with a cane, and I doubt the police would approve of me shooting the assholes for making me fall to the ground when they hit me. I've had too many close calls while buying food, including one SOB who leaned out the window and screamed at me to 'Get the **** out of his way', because I was 'Walking too ****ing slow' to suit him. Then he switched to Spanish and continued to curse at me. I was so sick & weak that day I needed a cart and my cane to walk. I wanted a M-72 to fix the crappy flame job on his jacked up pickup. -- You can't have a sense of humor, if you have no sense. |

The Aldi's chain has been doing it for years. Save-A-Lot started 'testing' them a month ago, and chose our area for the tests. None of the others are doing it, and Publix Supermarkets and a few other chains offer help. There are only a few things I buy at Aldi's, simply because no one else sells it. I will only buy what little I can carry, and only stop if I am within a few blocks for some other reason. I used to spend about $200 a month at Save-A-Lot. In the past month, I've spent about $40 there. -- You can't have a sense of humor, if you have no sense. |

No need to weld to the end if you've got enough drill sticking out; you can weld a lever to one side too. I have only a tiny angled piece sticking out, and I don't want to affect the heat treat on the part or cause any problems for the eventual anodizing. |

Thanks, * * * * Pete C. I have had some luck using a small high speed tool like Harbor Freight item 47869 and dental drills. It is not too fast, and I would not recommend it on any tap bigger than 3/32 ". The tap gets hot and loses its hardness to some extent. i have also kludged up a electric discharge machine using a drill press to hold the electrode. It was pretty simple. An isolation transformer to a voltage doubler. Then through a light bulb to a oil filled capacitor and on to a finishing nail in a dowel in the drill press. The light bulb acts as a resistor that increases in resistance if there is a short. The distance is critical . We ( I did this for and with a friend. ) set the stop on the drill press and could get a very slight movement by leaning on the down feed. We used kerosene and had the part immersed in it. Since the sparks all occurred in the liquid below the surface we did not have any fires. I do not recommend this unless you have a reasonable background in doing stuff like this. Lots of ways to get shocked or cause a fire. This is also not very fast. My friend had broken a tap off in a .45 slide. After doing all the playing, he took the slide to a machine shop and had them burn out the tap. Dan |

I would MIG weld a nut on the tiny bit of bit available. If looks is critical, I happen to have some copper tape that I would put on the part with the drill sticking through. |
