Author Topic: Straightening bent intermittent shaft?

I was stold that their entire shop is proprietary and that they have developed their own special machine tools and process over a period of decades. I was also told by them that they do not give shop tours. Will, I've been through LaVezzi at least 4 times. The first tour was so long ago that the tour was given by none other than Worth Baird and it was at the old Elmhurst location. The other three tours were given by Al LaVezzi himself and on one of the tours Dick Prather from Portland accompanied me. SOmeplace I have a picture of Dick out in front of the LaVezzi sign! I can definately say there are ALOT of special jigs and tooling they have developed but the machine tools themselves all seemed to be stanndard run of the mill stuff... mostly CNC. Lots of Hardinge stuff and 2- Studer air beaing grinders that are used to do the final grind on the radius and slots in the stars. Since LaVezzi also does medical and occasional military stuff there may be times when a tour was not allowed so as to expose a proprietary method or something like that. Remember the post that I made a few years back about the rough cut on the Century cams causing the lathe to burst into flames.... Dick and I were told that story by Al.

The use of a Phillips sprocket is a good option for the Prevost since they share the same 10.005mm bore  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 02-02-2007 01:59 PM                     I never had an issue with a pair of prevost 70 machines running interlock 3d we usually got 4 months out of a pair of sprockets  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 02-02-2007 03:44 PM                     quote: Gordon McLeod I never had an issue with a pair of prevost 70 machines running interlock 3d we usually got 4 months out of a pair of sprockets 4 months is pretty pathetic. Thats because they are not hard coated... just anodized... same as the Cinemecanicca 35/70 sprockkets were(gold). Cinemecanicca got smart having that steel 70mm only sprocklet made up by LaVezzi. An alumnium hard coated Century JJ or Kinoton sprocket will outlast the Italian sprockets about 5 to 1.
