Hi, Does anyone know how the square drive on the end of a flexi drive shaft is made? I guess its compressed, but is there a tool available for doing this? Ian |
| awemawson:
The ones on car speedo drives had a ground finish, but that doesn't mean they were compressed first then ground to size. |

I remember using a special Smiths tool for making speed-cable inners about 35 years ago (can't imagine anyone does that any more!) IIRC It was two pieces with three(?) sets of paired of 90° V-notches and some kind of clamping arrangement, to hold the cable while the tool was clouted with a hammer. Frank Ford has a how-to homebrew one here: http://www.frets.com/HomeShopTech/Projects/SpeedoCable/speedocable.html Bill |

Are you looking for a drive shaft for a RC boat? I use to race them for years and a lot of us got our shafts from used weedeaters. Personally I didn't like using the square shafts and used a round shaft with a collet instead. If you need a source for new 1/4" flex shafts with a round or square ends just let me know as I know of some suppliers that sell them for RC boat use. Dale P. |
