Tech Support wrote Is a "scooch" the same as when us Irish say "A Wee Bit"? Whoooah, there. I think not! The only time I've heard "a wee bit" was as in " I'll take a wee bit of the spirit for my cup here, if ye please!" In that case, I believe that did NOT mean a scooch! g -- Jim in NC |

My first thought was to use a brake cylinder hone. They should be available at most good auto parts stores or via the web. Mine has three stones and it wouldn't fit into the rear cylinder of my Pinto, so I removed one and repositioned the other two opposite each other. Then there is the West Virginia Tool and Die hone, a strip of emery paper duct taped to a wooden dowel chucked into a drill. -- FF |

Open to other ideas - MIke How much needs to be taken off? Charles Put the two washers in a piece of threaded rod. A couple more washers, that fit the ID of the tube, on the inside to locate the tube. Go easy with a file, or even a piece of plumber's tape. The chuck out of a burned up drill, sunk into a piece of hardwood, makes a nice live center in a pinch. |

Open to other ideas - MIke If your live end cone is big enough that takes care of that end. A wood dowel forced into the other end takes care of that end. Make your own dowel and LEAVE it in the chuck when you put the tube over it. If you move the wood it will never again be true to you. If you'd rather use a metal dowel/tube you may need to use Locktite™ to keep it from slipping. That's where the fun ends, removing the metal dowel/tube is a great deal of fun since heating everything to at least 300º to soften the Locktite™. Again, leave the dowel/tube in the chuck until you are done working. There is a third way if you have a piece of round stock long enough to go through the tube. The round stock has to be greater in diameter than the ID of the tube. Start by using a center drill on the end of the round stock to put your live end into to prevent wobble. Then turn the round stock down so you have a length longer than the tube and a slip fit. You then thread the end and use a washer and nut to secure the tube. The nut should tighten the tube against the shoulder where you turned down the round stock, not the chuck. Tightening against the chuck will ensure you pull the round stock out of the chuck when you tighten the nut. Again, leave the round stock in the chuck until the work is complete. Hex stock can also be used. BTW, you shouldn't use technical terms like "a scooch" in this group since it is obscure. I prefer "a tad." Dan, U.S. Air Force, retired |
