Hi Kirk, I have the Contourmaster version of that machine with the 215 to 5650 rpm drive. It was a Boeing machine, then went to a trade school where it acquired CNC via a Russian engineer. I bought it at auction for a good price since everyone was afraid of it. It came with a set of 40 taper toolholders and an ER20 collet adapter. If yours uses the cinci truncated 40 taper holders I hope you have them. Mine uses a large bronze nut to hold the toolholders into the taper. I made different thrust ring so I could also use ER40 collets. On the other hand if you have to build a spindle then you can make choices. Doing a non-tiltable spindle would be my choice ( a bit stiffer). I did implement the W in place of a Z and was not real happy with the result. I used a gear-head servo motor of limited power which may be the reason for my unhappiness. Moving the mass of X and Y to get Z seems like a poor way to do it. I'm implementing a Z on that machine now and it looks like < 50 W of servo motor will do it. My W has a glass scale on to so I can do repeatable setups. Good luck. It should be an interesting project. :-) Dave ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
