Never heard that one Darren :scratch: Sounds interesting though. Haven't got the MIG to test the theory though ::) Stot, 2 screws will hold fine in my experience. (1 screw does let go.... Got the T-shirt ::) ) an 80mm ball is huge.... Cool! :headbang: (brass walking stick top/kosh? :wack: :lol: ) Looking forward to the progress pic's :thumbup: Ralph. |

Well Ive ordered the metal from Macc, great price from them and had all the sizes I needed, Thanks for the heads up Jason, all steel and have decided on no bearing. I figure some moly paste on the steel will do the job nicely without introducing as much wear related slop, and the grease/paste can be re-applied during maintenance. Im after as big a radius as possible so I can get some sweeping curves rather than make huge balls. :bugeye: but I may have to make a couple just coz I can... :) Ill take a ton of pics and post up my plans over the weekend ( as long as the metal turns up this week ) as I try and make it. :proj: Cheers Stot |

Hi - you will enjoy the ball turner with or without the bearing. I did the bearing as a improvement after making the BT http://madmodder.net/index.php?topic=1822.0 I would advise that it is definitely not neccesary but it makes the BT so much nicer to use. Main thing I wanted to say was if there is any chance that you want a bearing - do it from the start -as it is more difficult to do afterwards. Gerhard |

One thing you should check before you start is the mounting point location and cross slide travel. While I was planning mine, I came across a few designs that have the rotation axis of the turret concentric with the cross slide mount point. However, when I checked on my machine (a Chester DB7VS), I found that the mount point axis wouldn't line up with the spindle axis before the cross slide came off its lead screw. The up-shot is that I needed to use one of the "turret on a plate" designs to gain the required offset. I used all-aluminium for mine, including the tool holder, and VBMT tips (idea blatently stolen borrowed from Ralph, I think :thumbup:). This was primarily as I needed it quickly and had suitable sizes in stock. If it becomes necessary, I'll replace parts as required. |
