John, See if you can find somebody in the UK that get's Model Engine Builder. In issue #24 there is a nice article on building a simple tubing bender for 1/4" dia. tubing. Bernd |

Thanks guys for the flow of helpful ideas and links. But to be honest Bogs has once again proven his superior engineering skills with his brilliant and innovative solution. (Bogs, it worked very well, the only problem I have now is straightening the drill bit) John-Som |

(Bogs, it worked very well, the only problem I have now is straightening the drill bit) John-Som --- End quote --- John-Som That should not be too hard to straighten. Fasten the shank end of the bent drill bit securely to a light chain. Now get out your heating equipment and heat the bent drill bit up to the point just before it is molten. At this point swing chain with bent drill bit in a circular motion at a high rate of speed. Now centrifugal force is your friend and when you reach the correct speed the drill bit will straighten. Be careful not to swing it too hard or you may cause the drill to straighten too much and you will loose the spiral. Come to think of it, if you do loose the spiral maybe it would work OK as a reamer. In any case pay careful attention to the temperature after it has straightened and you can plunge it into a can of oil to temper it again without having to reheat it. :lol: :lol: Cheers :beer: Don |

There is another very nice tube bender in the latest issue of Model Engine Builder that dropped on the doorstep today. I have a set of external springs that avoid the problems of getting stuck in the tube but they are still quite hard to remove from the outside. You can also get the small record bender that does 1/8,3/16 & 1/4 but I did not find it that good on copper. J PS when melting out the solder make sure you start heating from one end of teh tube, I still have solder stuck to the workshop ceiling where I heated the middle first ::) |
